y SPECIFICATION forming part of Letters Patent No. 281,844, dated Ju1y24, 1883.

Application filed April 5, 1883.

.To all whom, it may concern,.-

Be it known that I, NATHAN J. GUYLE, of Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Excavator and Wrecker Combined, of which the following, taken'in connection with the accompanying drawings, is a full, clear, and exact description.

This invention has reference more particu-` cranevto the axle of the car which carries the crane, all as hereinafter more fully explained, and specifically set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation of my improved crane. Fig. 2 is a plan view of the saine with the boom broken away. Figs. 3, 4, and 5 are enlarged detail views of the jack and that portion of its actuating mechanism which is adjacent there to, Fig. 4 being a sectional view taken on line y y in Fig. 3. Fig. 6 is an enlarged vertical transverse section taken on line x :u in Fig. 2. Fig. 7 is an enlarged vertical transverse section of the upper portion of the post or mast and the sheave-carricr mounted thereon. Fig. 8 is a horizontal section taken on line z 'z in Fig. l; and Fig. 9, a vertical section on line 1 l, some of the figures having portions broken away to better illustrate the invention.

Similar letters of reference indicate corresponding parts.

A represents the platform or main supporting-frame of the crane, mounted on car-trucks,

(No model.)

therefrom, and fastened at the end to the frame A. The lower portion or foot of the post Pis provided with a circumferential groove, a, in which is fitted to revolve a collar, Z), which is composed of two diametrically divided sections, so as to allow it to' be applied to said groove, said collar being clamped together and the turn-table secured to the collar in the manner hereinafter more fully described.

The collar b is formed, on two diametricallyopposite sides and equidistant from the center of the collar, with two parallel rabbets, c c, on-

which rests and issecured the turn-table T, which is framed to form an opening through which the rigid post P protrudes, and with parallel skids or beams on 4two edges of the openings, which beams rest in the rabbets cc aforesaid, and are firmly bolted or otherwise fastened thereto. The forward port-ion of the collar b has firmly secured to it or integral with it two concave sockets or steps, d, in which rests the foot of the boom B. Said boom I prefer to construct of wrought-iron, its foot being convexed corresponding to the step d, so as to allow the suspended end of the boom to swing vertically, and to also transmit the strain directly to the step.

@represents a hollow cap pivoted on top of the postI), and having pivoted to it the usual sheaves, which carry the chains N and O, by means of which the boom B is raised and lowered and the dipper B is operated, said chains being extended to and wound upon drums S and S', journaled in suitable bearings on the platform or frame A, back of the mast, in the usual manner. Said drums receive their requisite motion from the driving-shaft U by a train of gearing, the gears of the drums S and S being mounted loosely on the shafts of the drums, and when required to transmit motion to the drums said gears can be fastened by means of the usual friction-clutches, V V, controlled by suitable manipulating-levers, V V.

In order to properly sustain the sheave-car rying cap C, I prop the forward-projecting portion of said cap by means of diagonal braces D D, extended from the collar b to the cap C.

The collar b, turn-table T, boom B, cap O, and its braces D D all rotate about the stationary post I), and receive their motion in the usual manner by chains rr, attachedto and extended IOC 2 l sensa/1 around the periphery of the turn-table T, 'and wound in opposite directions around a drum, lV, which is mounted loosely on a horizontal shaft, K, journaled in suitable bearings fixed to the platform A back of the driving-shaft U. By means of a clutch, s, connected to the shaft K, and adapted to be thrown into and out of connection with the drum NV, the latter can be set in motion when desired, the rotation of said drum unwinding one chain r while winding up the other chain, and thereby imparting rotation to the turn-table T, which, by its connection with the collar I), carries with it the said collar and parts supported thereon, as before described.

F represents the post or prop of a jack by which to raise the platform A and give it vthe necessary support when thecrane is in operation, said post being connected with the bedpiece I by a ball-and-socket joint, 7c, so as to allow said bed-piece to conform to the unevenness of the ground without straining the post.

In order to obtain a perfect holdbetween the post and bed-piece, so as to allow the former to raise the latter, I make the socket reach above the horizontal diam eter of the ball and embrace the greater portion thereof, the socket being made in two parts, countersunk in the adjacent sides of two timbers, which receive the ball between them, and are firmly bolted together, as illustrated in Fig. 5 of the drawings, four of such jacks (one at each corner of the platform) being generally appliedv to the frame A. In order to operate saidv jacks by the same power which operates the crane, I construct the jacks in the following manner, and employ in connection therewith the following instrumentalities:

To each corner of the frame A, I attach a stout iron shoe, E, vertically through which is extended a prop or post, F, which is adapted to slide longitudinally or vertically therein. That side of the prop F which faces toward the opposite end of the frame A, I provide withA a ratchet, e, and in an opening in the side of the shoe E slides a dog, f, adapted to engage the ratchet e, and thus arrest the upward movement of the prop.

The dog f is provided with a lug which protrudes through the side of the shoe, and with the outer end of said lug is connected one of the arms of a cranked lever, a, pivoted to the cross-beam of the frame A, to which the shoe E is attached, as illustrated in Figs. 3 and i of the drawings. To another arm of the lever n is connected a rod, o', which passes through a guide-block, u, and has its opposite end connected with another rod, o, which is extended toward the opposite end of the frame or platform A, where it is connected with the rod o', which is arranged in relation to the jack at that end of the platform in the same manner as the inst-described rod, o', is arranged in relation to the jack at the opposite end of the platform.

rIhe connection between the rods o and o is made so as to afford a certain amount of slack or longitudinal play between the `engaging parts and allow the rod o, when moved in either direction, to draw on one rod, o, without disturbing the other. 'Ihis connection of said rods is represented in Fig. l of the drawings in the form of a longitudinal slot, t, near the end of the rod o, the end of the rod o sliding through an aperture in the solid portion of the end of the rod o, and being provided with a head in the slot t, by means of which head said rods receive the necessary hold on each other, the slot t being of the requisite length to afford the longitudinal play aforesaid.

Between the guide-block a and cranked lever n the rod 0l is provided with a fixed collar or shouldena, and between this shoulder and the block u a spiral spring, p, surrounds the rod o and exerts an expansive force against the shoulder u, and thereby pushes the rod o toward the cranked lever n. The latter is thus caused to normally hold the dog in engagement with the ratchet e of the jacking-post F.

By means of a lever, c, fulcrumed on the platform A and connected with the rod o, the latter can be shifted in either direction to draw the dog f out of its engagement with the ratchet of the j acking-post at either end of the frame or platform The jacks are operated by the following instrumentalities. The post F is provided with arack, r, on the side facing the platform A, and with this rack engages a pinion, g, situated in a cavity in the shoe E and fixed to a short axle, g2, which projects through the side of said shoe facing the jack at the opposite end of the platform, and has fixed to its outer end a gear-wheel, g, as best seen in Figs. 4 and 6 of the drawings. Along the side of the platform A is extended a line-shaft, G, which is divided intermediately of its length, and has the two adjacent ends journaled in a supporting-arm, w, which is iirmly attached to the IOO IIO

frame A and projects outward therefrom, as A shown in Fig. 6 of the drawings. The opposite ends of the line-shaft are journaled in boxes w on the shoe E, before described. (See Fig. 4 of the drawings.)

The two extremities of the line-shaft Ghave attached to them a pinion, l1., which meshes in the gear g. On the adjacent ends of the respective sections of the shaft G are loosely mounted two miter-gears, il z', back of each of which is a sliding clutch, Z, which is arranged to rotate with the shaft G, the two clutchesbeing operated by a single bar, Z, reaching over the two gears i z', and being connected with a shifting-lever, Z2, which projects above the platform A, convenient for manipulation, said arrangement allowing only one of the clutches to be thrown into engagement with its respective gear fr' at a time. Between the two gears for transmitting` motion to the line-shaft on that side of the platform.

On the counter-shaft is fastened a sprocketwheel, Zt, which, by an endless chain, on, is connected with a sprocket-wheel, Z3, attached to the boom-swinging shaft K, hereinafter described. At the side of the sprocket-wheel Z3 a clutch, m2, slides on the shaft K, and is adapted to engage with said sprocket-wheel, and thus compel the same to rotate with the shaft K. This shaf't receives its motion from the main driving-shaft by a train of gearing, 1, 2, 3, and 4, as shown in Fig. 2 of the drawings.

Vhen it is desired to raise the platform A, the clutch m2 is to be thrown into engagement with the sprocket-wheel Z3, the rotation of which transmits motion to the counter-shaft G by the medium of the chain mand sprocket-wheel Z". Then by means of the lever ZZ one of the clutches Z can be thrown into engagement with the adjacent miter-gear Z, and thus cause its respective shaft-section Gto revolve. The revolution of this shaft transmits motion to the gear g/ by the medium of the pinion h on the extremity of said shaft, and with the gear g revolves the pinion g, which engages the rack r of the j aching-post. When the platform has been raised to the desired elevation, the motion of the aforesaid train of gearing is stopped by releasing the wheel Z:s from the clutch m2, or by throwing the clutch Z off the gear Z. The dog f, engaging the ratchet e of the post F, retains the platform in its elevated position.

When it is desired to lower the platform A,

the dog can bey thrown out of the ratchet e by means of the lever c, which is connected therewith in the manner hereinbefore described. v In order to utilizethe crane-operating power for propelling the car on which the crane is mounted, and to obtain this propelling-power without the employment of additional shafting, I mount loosely on the counter-shaft G two sprocket-wheels, Z, which are firmly united or formed in one piece, a sliding clutch, m3, being connected to the shaft at one side of the sprocket-wheels, to lock the latter on the shaft and compel them to rotate therewith when desired. One of the axles L of each truck of the car has fixed to it a sprocket-wheel, Z2, and the two latter wheels are connected with the two wheels Z Z by endless drive-chains m', one of which is crossed, so as to drive the two truck-axles in the same direction.
