No. 7964.- Variable Cut-off, regulated by the Governor.

What I claim as my invention, and desire to secure by letters patent, is regulating a variable cut-off valve by a motion derived from and corresponding to that of the governor, by means of a toe or vibrating lever attached to the rock shaft, acted upon by revolving pins or cans, when either the cams are made to vary in position with respect to the toe, or the toe in length with respect to the cams; the whole machinery being constructed and acting substantially as herein described.

HENRY WATERMAN.

No. 7965.-Method of adjusting the stroke of Trip Hammers.

Having thus described my invention, some of its advantages I claim to be as follow:

First. Simplicity and cheapness of its construction; and,

Second. Its peculiar adaptability to water power, while at the same time it seems to combine nearly all the capacities and facility of regulation of the steam hammer.

What I claim as my invention, and desire to secure by letters patent, is the construction of a trip hammer, in which the hammer is raised by cams, not acting directly upon the hammer or the helve, or a projection from the same, commonly called the lifting leg, but by the intervention of a movable joint, so constructed as to grasp or clutch the lifting leg at any required height, the position of the same being governed by the regulator, which may be constructed in the form of an inclined plane or any equivalent contrivance for raising and depressing the joint at the will of the operator; the whole being constructed to perform the peculiar services substantially in the manner herein before set forth in this my specification.

scribed.

I also claim the combination of belts, pulleys, clutches, screws, and screw wheels, with the sway bar and triggers, by which a self-acting, advancing, and retrograding motion is given to the movable roller, each motion changing to the other, when caused so to do, by the hand of the operator, but self-arrested and stopped by the set of the triggers, substantially as specified.

P. G. GARDINER,

No. 7969.-Improvement in connecting Trucks with Car Bodies.

I also claim the arrangement by which the upper box or boxes are held in their places while the one below is removed and another inserted in its place.

Also, the arrangement at the rear and bottom of each box by which the tin slide is removed, thus allowing a convenient opportunity for clearing the bottom of the bee boxes as described.

NATHANIEL POTTER.

No. 7971.-Improved Window Curtain Fastening.

I claim the construction of rack-pulleys for window shades, by fixing the pulley, over which the cord of the shade-roller runs, upon a stem, having a plate sliding on the front outer face of the rack box, attached to a thin plate or fin passing through a slot in said face, extending the length of the box, the said fin projecting upwards, and terminating in a point, which acts as a pall against ratchet teeth made in the bottom of said box, or else the said fin projecting downwards and having a cross pin through it, acting against ratchet teeth in the upper and inner side of said box; the said stem and plate, in addition to the sliding motion along the box, having an oscillating motion on the upper or lower edge of the plate, by means of which the upward pressure of the cord on the pulley holds the pall or pin against the ratchet teeth or the downward pressure of the hand, carries the pall or pin out of the line of the teeth and permits the pulley to be moved upwards when required, substantially as set forth in this specification.

HUGH GUYER.

No. 7972.-Improvements in Steam Drilling Machines.

What I claim as my invention, and desire to have secured to me by letters patent, is the combination of a direct action steam drill, in which both engine and drill are mounted on a frame, which slides in a swinging frame, capable of being adjusted in any required position with the apparatus, substantially as herein above described, which is connected with, and actuated by, the cross head of the engine for causing the sliding frame to move along the swinging frame towards the rock.

No. 7976.-Improvement in Piano-Forte Action.

What I claim as new in my invention, and desire to secure by letters patent, is:

First. Hanging the hammer shank on a hinge or joint, d, at a distance from its end, and effecting its communication with the fly lever or jack by means of a lever, L, which is hung on a fulcrum, i, at a distance from either end, and is connected at one end by a hinged or jointed link with the end of the hammer shank, in such a manner that when the fly-lever is raised by the key, the end of the hammer shank is drawn down, and the hammer thrown up to the string; or by any other means substantially the same.

Second. The universal repeating spring, m, attached to the lever or butt upon which is formed the projection, K, or its equivalent, through which the fly lever communicates with the hammer, for the purpose of raising it, and working upon the end of the fly-lever, in the manner substan tially as and for the purpose herein set forth. This I claim, without reference to the precise form of the projection, or of the spring herein shown, as various modifications may be made for producing the same effect.

Third. Attaching the check-wire to a hanging or hinged butt, Q, operated upon by the key, in the manner substantially as described, so as to produce the same effect as if attached to the key, for the purpose of allowing the key to be easily taken out.

Fourth. Securing or placing the regulating screw, r, for controlling or regulating the escapement of the fly lever, in an arm, N, or its equivalent, upon the lever upon which the fly-lever acts, by which the action of the said screw upon the fly lever is more gradual and easy, and the jarring or concussion produced when the screw is stationary is avoided.
