SPECIFICATION forming part of Letters Patent No. 541,409, dated J' une 1B, 1895.

Application led February 18, 1895. Serial No. 538,828. (No model.)

To a/ZZ whom, t may con/cern:

Be it known that I, JABEZ L. WOODBRIDGE, a citizen of the United States, and a resident of Vetherstield, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Automatic Gallows, of which the following is a full, clear, and exact description, whereby anyone skilled in the art can make and use the same.

The object of my invention is to provide an apparatus or machine by means of which the penalty of capital punishment may be inflicted with certainty by devices that are to a certain extent automatic, but which remain wholly under the control of the public ofcer until the final moment.

To this end my invention consists in the details of the several parts making up the apparatus as a whole and in the combination of such parts as more particularly hereinafter described and pointed out in the claims.

Referring to the drawings, Figure l is a view of the apparatusas arranged in a room. Fig. 2 is a view in elevation of the verticallymovable platform, the weight, and the connected mechanism. Fig. 3 is aplan view showing the arrangement of the several levers and bolts located between the vertically-movable platform and the weight. Fig. 4 is a view in side elevation showing the arrangement of the platform-controlling lever and of the platform-lever. Fig. 5 is a view of the dial and mechanism for operating the index-hand.

In the accompanying drawings the letter a denotes the iioor of a room, preferably raised as shown in the accompanying drawings, leaving a space thereunder in which is located part of the operating mechanism. The letter b denotes the weight guides; c, fthe weight, and d a rope in the end of which the usual knot is made in such manner as to form aloop, the knot being one that will not slip.

The letter e denotes the weight lever that is pivoted in a suitable support with one end underlying and supporting the weight c, the other end of the lever being in engagement with the tripf. This trip f is supported on a pivot, with one end engaging the weight lever e, and the opposite end connected with a trip rod g. A rope or like flexible connection h is also attached to one end of the trip f, the opposite end of the rope passing around the shaft of an index hand i, the hand overlying the face of a dial j. :This dial is supplied with characters, as numerals, to denote the movement of the index hand, in the form shown in the drawings the numbers-in a series of 5 up to 40 denoting seconds, and the parts just described are so adjusted that when the tripf is in its normal position the index hand points to 5, and when this trip has moved to a distan ce sufficient to release the weight from *1ever e the index hand will have been moved around to 35, denoting that a period of thirtylive seconds has elapsed between the conimencement of movement ofthe tripf and the release of the weight lever c.

The trip rod g is connected to afollowerg located-in a valve case g2. Openings g3 are formed in the upper part of the valve case,

and an opening g4 in the lower part of saidv case. Underlying the opening g4 is a valve k, having therein a valve opening lo. VThis valve is located in a slide way, and is adapted to move so that the valve opening 7e will register with the opening g4 in the bottom of the valve casing, the slide ways in which the valve moves being preferably located on a standard Z. A valve lever mis pivoted to the standard Z, one end of the valve lever being also pivoted to the valve la.

A platform levernJ is pivoted to a standard n underneath the platform jp, and a connecting rod o is pivoted to the upper end of the platform lever and to the valve lever mat a point between its pivotal support and connection of both the platform lever and the valve lever, but this rod may or may not be used, it being obvious that its function is the ,same as the connecting rod o and acts merely as an aid in the operation of the device.

To the shaft n.2 to which the platform lever n is secured is also attached a platform holding leverp', a support p2 extending from the vertically movable platform p downward and resting on the platform holding lever p forward of its pivotal support. Stops p3 are located underneath theplatform p in a position to limit the extent of its downward movement, springs p4 being-interposed between the platform and the stops. A platform controlling lever q, see Figs. 3 and et of the drawings,

ICO

is pivoted Vto a standard q', this lever being in the form of a bent lever, one arm of which underlies the forward end of the platform holding leverp, and the other arm of the lever being pivotally connected with the connecting rod q2, the opposite end ofsaid connecting rod being attached to the foot lever r pivoted in the standard fr', a foot piece r2 being secured to the end of the foot lever r.

A releasing lever s is pivoted to a standard s' with one arm underlying the platform holding lever at a point back of the pivotal sup; port of the latter. A connecting rod t is pivoted to the opposite arm of the releasing lever s, the opposite end of the connecting rod z5 being pivoted to a foot lever t pivoted to the standard t2, and a foot piece t3 is also secured to the foot lever t. The general construction of the releasing lever s', the foot levert and the connected mechanism is the same as that shown and described with reference to the platform coutrollinglever, q, foot lever r and connected mechanism.

rlhe movement of the follower g is coutrolled by the pressure on the under side' of the follower. A fluid or solid substance may be used to control its movement. Shot are preferably used, as the operation of the device can be more easily controlled than with the use of less Vsolid substances.

In the operation of the device the movable parts being in the position shown in Fig. l of the drawings, as pressure is put upon the vertically movable platform n, the latter is depressed till it encounters the stops p2. This operation rocks the platform lever n and the valve lever m to a distance sufficient to cause the opening in the lower part ofthe valve case g2 and that in the valve g to partially register each with the other, and Iallow the shot to flow out of the valve case. As the shot flow from the case the follower g is depressed under the action of the weight c and connected mechanism, until the weight lever e is released from the tripf, causing the weight to fall and the rope d to be suddenly drawn upward.

In the downward movement of the trip f the pull upon the flexible connection h causes the index hand ion thedialj to be revolved, and as before stated the time that will elapse from the release of the shot by the mechanism herein described to the release of the weight v lever from the trip will be just thirty-five seconds, as denoted on the dial. This gives sufficient time in which the knot may be properly adjusted and it is held in this position by the attendant until the release of th'e weight. This necessitates that the blow caused by the fall of the weight shall be given at the proper place to effect the desired result.

By means of the platform controlling lever and releasing lever s the movement of the shot from the case can he easily controlled. If it is found that they are running outtoo ,fast to enable the required operations to be performed before the release of the weight a pressure upon' the foot lever r2 throws the' platform holding lever p and consequently vertically movable platform p upward, thus shutting off the flow of the shot. If the required operations are performed quickly and it is desired to hasten the operation of the device a pressure upon the foot lever t will cause the platform holding lever 1J to be rocked farther over, this movement causing the opening in the valve through the connected mechanism between the platform lever n and valve lever 'm to register with the opening in the bottom of the valve case when all of the shot will immediately flow out from the case causing the weight c to drop at once.
