in advance. By this means the progress of a train from station to station is distinctly marked, and should any obstruction or accident occur on the line, the position of the signals informs the driver of an approaching train of the circumstance. In addition to these signals, a bell is also provided at each station, which commences ringing on the passing of a train, and continues to do so till it has passed the next adjacent station. Several modifications of the apparatus are shown and described.

The claim is to the combination of parts of which the apparatus is composed, and particularly the construction and arrangement of the cylinders for the purpose of conveying signals or telegraphic communications, together with all modifications of the same.

THOMAS FULLER, OF SALFORD, LANCASHIRE, MACHINE-MAKER, for certain improvements in machinery, or apparatus for combing or preparing wool, or other fibrous substances. Petty Bag Office, August 8, 1841.

These improvements apply to the "double circular wool-combing machine," patented by Mr. John Platt, in 1827. In that machine the teeth of the circular combs were set parallel, or nearly parallel, to the axes of the comb

wheels; the present improvement consists in setting the teeth at an angle of about 150°.

The second improvement consists in placing the usual drawing apparatus of the old machine at an angle of about 40° with the horizon, so as to enable it to draw off the fibres of the material which has been combed from the teeth of the comb-wheel, more effectually than heretofore.

The claim is, 1. To the setting the teeth, pins, points, or broaches, of circular combs, in the face of the comb-wheels, in positions forming acute angles with the axes of those wheels. 2. To the adapting the position of the drawing-rollers to a suitable angle for drawing off the slivers from the comb-wheels as described.

Intending Patentees are informed that they may be supplied gratis with Printed Instructions, containing every particular necessary for their safe guidance, by application (post-paid) to this Office, where is kept the only COMPLETE Registry of PATENTS ExTANT (from 1617 to the present time); Patents, both British and Foreign, solicited. Specifications prepared or revised, and all other Patent business transacted with economy and despatch.

BY CHARLES BERWICK CURTIS, ESQ.

We duly noticed Mr. Curtis's specification at the time of its enrolment (vide our 939th Number,) but as that notice was necessarily brief, and imperfect for want of the explanatory drawings necessary for making it intelligible, we now return to the subject for the purpose of explaining more clearly the nature of this invention, which seems well adapted to answer the purpose inten led; and if applied to any line of railway, to go very far towards preventing those fearful accidents, the frequency of which led to the designing of this, and several other somewhat similar contrivances, which have been recorded in our patent offices within the last six months.

This patent was granted on the 19th of January 1841, and the following particulars, taken from a pamphlet recently published by Mr. Curtis, will, with the drawings annexed, show the nature of his invention.

The methods comprised in the patent, are intended to be carried into effect by means of self-acting apparatus; the distinguishing character of which is, that at every time when a train travels along that part of the railway, where any such apparatus is situated, so as to pass by that apparatus, the same will exhibit a signal immediately on the train so passing by, and will continue to exhibit the signal without alteration in its appearance, so long as there will not have been sufficient time for the said train to have advanced far enough along the line beyond the apparatus, to permit of any succeeding train to follow after the said first-mentioned train, and the signal so exhibited will give information to the driver of any such succeeding train which may happen to come up in sight of the apparatus that he is to stop and not proceed; and which apparatus, after having so exhibited such signal, then, in due time, begins to withdraw the same gradually from full view by the motion of suitable wheelwork, and whilst so withdrawing, the said signal is caused to change its appearance in some marked manner, in order to give information to the driver of any train which may happen to arrive within sight of the apparatus

whilst the signal is so exhibiting in its changed appearance, that such train may proceed slowly, but not at full speed; and the said apparatus, also, after having so exhibited the signal in its said changed appearance, wholly withdraws the signal from view, or withdraws the same into an inactive or resting position, and then the motion or action of the apparatus ceases; and it continues in its inactive or resting position until another succeeding train passes, and the signal in its said inactive or resting position, serves to inform the driver of any such succeeding train which may happen to arrive in sight of the apparatus when in that state, that he may proceed at full speed without risk of collision with the preceding train.

Fig. 1, on our front page, represents an apparatus fixed to a bridge which crosses the line, or at the entrance of a tunnel.

CC, line of railway; D, locomotive engine, to show the manner in which the action is communicated to the apparatus.

a, piece of wood attached to each side of the engine.

b, curved lever-arm, or trigger, or camb, fixed upon a horizontal axis (d,) which extends sideways, in order to reach towards the side pier of the bridge, which axis is sustained by suitable bearings set upon a sleeper of wood or stone.

e, a short lever extending horizontally from the axis (d) towards the face of the pier.

f, upright rod, joined to the end of lever (e,) and carried up the face of the pier.

gg, guides fixed to secure the rod (f)

h, an oblique link, connecting the upper end of the rod (f) with the lower end of the lever (i,) being bent in the form of (i) a goose-neck, whereof the fulcrum is sustained by a centre-pin in a bearing-bracket (k) fixed in the wall.

j, three arms radiating from the centre arbor of an apparatus of wheelwork, with liberty to slide backwards and forwards thereupon, and kept out to its working position by means of a

curled spring; the arms are furnished at the extremities and on the outer face with short pins.

HIK, box or screen fixed on the face of the bridge, partly or wholly over the arch, placed in a horizontal line, or nearly so, with the centre arbor of the three arms (j), projecting a short distance from the wall; coloured in three compartments, black at top, green in the middle, and red at the bottom, the red and black being about one quarter each of the surface, and the green taking up the intermediate space.

Fis a signal at the end of a lever n, p, G, having its bearing at p. The signal consists of a rim of iron, enclosing two pieces of coloured glass, the top piece being red, and forming about one-third of the surface, and the lower part being green, and forming the other part. On the top of the rim, a round plate or pointer, painted white, is fixed by a strong wire, cranked so that it shall work freely through a groove cut in the front of the box HIK, and traversing over the face of the box.

G is the end of the lever to which the signal Fis fixed. J, a counterpoise to balance the signal F. L, the round plate, or pointer. N, the position of the lamp for night-signals, in front of which signal F falls.

p, the bearing or fulcrum upon which the lever n, p, G works. n is the point of lever (n, p, G) acted upon by the pin upon the three arms (j). r, the guide to secure the end of the lever. S, stop for the end of the lever (n, p, G). The action is as follows:

the

Upon an engine passing the spot where such apparatus is fixed, the piece of wood, a, strikes in a glancing direction the trigger or camb b, which depresses it about 14 inch, turning by that depression the arm d, and raising the short lever e, which forces up the rod f, and by means of the oblique link h, drives out the lower end of the bent rod or gooseneck i, which drives the head of the same against the centre of the three arms j, and presses them back upon the arbor of the wheelwork. The end of the lever n, p, G, is held in its resting position, or behind the screen or box by one of the pins at the extremity of the three arms j. As soon, therefore, as the arm is pressed in, the pin is withdrawn from its hold, and the

lever n, p, G, being free, falls by its own weight, and exhibits the glass-field signal F, below the screen, in front of the lamp at night, and draws down the white-painted plate or pointer from the compartment painted black, to the front of the red compartment at the lower part of the screen.

The wheelwork now begins to be in action, and that arm of the arms, (j,) which is next in rotation, moves slowly round, without at first having any intercourse with the lever, n, p, G; at length it arrives at the point of contact, and then commences to press down the short end of the lever, and the signal Frises gradually behind the boxing, withdrawing the red portion of the signal from before the lamp, and carrying the pointer over the red compartment of the screen, or upon the green compartment, showing by degrees an altered appearance of the signal during the day, or a green light during the night, and the white plate or pointer continues to traverse the green compartment, and the signal diminishes at the upper limb, still showing for night a green light until the signal arrives at its resting place, carrying the white plate or pointer on upon the black compartment, and then being withdrawn entirely from view, discloses the lamp in its regular white colour. The action of the wheel-work is now arrested, and remains at rest till the passing of the next train.

The notice which the apparatus exhibits to drivers of trains is as follows: the signal, after being released by a preceding train, remains exhibited motionless for about 3 minutes, and it consumes about half-a-minute for the wheel-work, when it begins to operate, to raise the lever so far up as to withdraw the red portion of the signal, or conceal one-third of its area, and to raise the white plate or pointer from the red compartment on upon the green. A driver, therefore, arriving at the spot, and observing the whole of the signal visible, and the pointer upon the red, or the red light at night, is informed that the preceding train has passed less than four minutes a-head of him, and that it is dangerous to proceed. If upon his arrival he observes that one-third of the signal is withdrawn into the screen, and the
