WHEEL-SHOVEL.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed January 24:, 1907. Serial No. 353,924.

To all whom it may concern:

Be it known that l, OrraltLEs THOMAS Hooxwxx, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful lmprovements in heel-Shovels, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in wheel-shovels adapted to be used for grading, excavating and fills and in other relations where it is desired to expeditiously load and convey limited quantities of earth or other material from one place to another over short hauls.

One of the objects of my present invention is to relieve the horses from excessive strain and mutilation by providing the supporting frame of the shovel with a forwardly extending reach bar and pivoting the front end of such reach bar directly t-o king-bolt of the front running gear to which the pole for the horses is connected in the usual manner for four wheeled vehicles.

A further object is to pass the reach between the upper and lower cross bars of the hounds of the front gear l at the rear of the axle while the pole is attached in the usual manner to the front end of the hounds in front of the axle whereby the downward and rearward pull or resistance caused by drawing the front end of the shovel into the earth produces a downward pressure upon the rear ends of the hounds thereby tilting the front ends of said hounds and pole attached thereto upwardly and thus relieving the horses from such excessive load or resistance and also from the excessive vertical and lateral vibration of the shovel.

A still further object is to provide means under control of the operator from the seat of the vehicle whereby the shovel may be readily dumped without the aid of an extra employee.

Another object is to provide adjustable means for retaining the shovel in its digging position against overturning as the vehicle is drawn forward in the act of loading. l i

In the drawings-Figures l and 2 are respectively top plan and side elevation of a wheel-shovel embodying the various features of my invention, the wheels nearest to the point of view in Fig. 2 being removed. Fig. 3 is a perspective view of the detached shovel and axle showing the detent for preventing overturning of the shovel during the operation of digging. Fig. l is a side elevation of the rear portion of the shovel supporting frame showing the shovel in its dumping position in full lines and in its (ligging position by dotted lines. Figs. 5 and 6 are enlarged top plan & side elevation respectively of a portion of the detent and one of its supporting bars.

As best seen in Figs. l, 2, and 4, the shovel as lfis provided with opposite side straps -2- rigid l thereon and having their forward ends pivotally connected at to the rear ends of the side bars 4 of a main supporting frame having a central lengthwise l reach-bar or tongue the front end of which is i passed between upper and lower cross bars 6l of the l hounds #7# of a front running gear -8- and is pivl otally connected to the king-bolt as -9- of said front i running gear to permit the rear gear as the rear axle y x-l0- and rear, wheels llf together with the shovel 'y --land its supporting mechanism to shift from side to side while the cross bars -G- which engage the l reach-bar -5- at the rear of the front axle as *l2* serves to hold the shovel supporting frame against y undue vertical movement and also relieves the pole as -l3- from the excessive vertical and lateral vibrations and strains to which the shovel is subjected during the operation of digging or loading. i It will be seen upon reference to Figs. l and 2 that i this pole -l3 is connected in the usual manner to i the front ends of the hounds in iront of the axle -12- by means of a pivotal bolt letwhich permits vertical vibration of the hounds independently of the pole and thereby relieves the horses from excessive vibrations and strains to which the reach is subjected during the operation of loading.

Rigidly secured to the opposite sides of the shovel lare upright iron straps or hangers l5- which are securely connected at -lG- at their upper ends to the front ends of a vertically rocking frame -l7-, the latter being rigidly secured to the rear axle l()-. This rear axle constitutes a part oi the frame #17- and its central portion is arched upwardly above the axis of the wheels -llupon which axis the frame -17- swings.

The side bars of the frame 17- are united at the rear of the shovel to form a handle lS- by which said frame may be rocked vertically upon its axis as ]9- which in this instance is coincident with axis of the wheels and owing to the fact that the shovel supporting hangers -15- are secured at -l6- to the front end of the frame *17* in front of the axis 19 and between the latter axis and pivots -3- connecting the shovel to the rear ends oi the frame bars -4, by elevating the rear end of the frame -17- to the position shown by dotted lines in Fig. 4, the front or digging ends of the shovel will be tilted downwardly to the dotted position shown in said Fig. 4 in which l position the bucket is held by a detent or catch 20 which is pivoted at 2l to the shovel -land is connected by a link -22 to the front end of the frame -l'7-, said link -22- serving to rock the catch 20vinto engagement with a stirrup F23 on the main supporting `frame as the front end of the i shovel is thrown downwardly by the upward rocking i movement of the rear end of the frame -l7-. i As a further precaution against overturning of the claim the shovel to engage the innerface of the upper edge of said shovel and thereby brace the latter against upward and forward movement during the operation of digging. I

The shovel is now in position to load by drawing the vehicle forwardly and as soon as loaded the frame-l 7` is returned to its normal position which elevates thev shovel, the latter being held in this position by a detent -26*. v

The general construction of the shovel and its supporting and tilting mechanism hereinbefore described except the detent consisting of the arms M24- and cross bar 25 for holding the shovel against'overturning during the operation of loading is substantially the same as what is commonly known as the Syracuse wheel scraper7 manufactured by the Syracuse Chill Plow Company, and therefore applicant does not herein shoveland its operating mechanism hereinbefore described except as it enters into combination with the connections with the front gear through the reach-bar -5- and also with the gravity detent t25-- and the means controlled by the operator from the seat ol' the vehicle for dumping the shovel as will be presently described. This dumping mechanism consists essentially of a cable -30 having its rear end passed over a sheave L31- on a bracket h32k on the rear axle and connected at -33 to the frame lr/ or handle 18` while its front end is attached to a winding drum `34- provided with a ratchet wheel `35- which is adapted to be engaged by a pawl 3(ion a lever -,37-, the latter being loosely mounted on the shaft of the drum -34h so as to be moved .back and forth in winding the cable on said drum, said lever being located in proximity to a seat -38- which is supported upon a spring arm -39- 'on the reachbar -5-.

The central portion of the cable -30- is guided on an intermediate sheave -40- which is supported upon a bracket 4l on the reach-bar. Mounted upon this reach-bar is a catch 42 having its free end located in the path of the rear end of the frame 17- to engage the latter and hold it in its dumping position.

Assuming that the shovel is in its normal up-position and empty and that it is desired to load the same, the detent `2ois first detached by means of its hand piece as -26- after which the operator on the ground elevates the rear end of the rocking frame -l 7- thereby depressing the front end of the shovel to the position shown in dotted lines in Fig. 4 during which operation, the upwardly arched central portion of the rear axle is thrown forwardly thereby drawing the arms *24%- and connecting cross bar -25- in the same direction until the rear face of the Cross bar drops automatically into the rear end of the shovel forming an engaging shoulder or detent for engaging the inner face of the upper front edge of the rear end of the shovel and resisting any tendency of the shovel to overturn during the operation of locating, which is accomplished byr drawing the vehicle forwardly over the ground to be excavated.

As soon as the shovel is filled the rocking frame 17- is returned by the same operator to its normal position and locked in such position by the detent `26- wh ereupon the load may be conveyed to the desired locality where it is to be dumped.

As soon as the dumping ground is reached the operator or driver on the seat of thevehicle may operate the lever `37- backward and forward to rotate the drum --34 and wind the cable -30- thereon thereby elevating the rear end of the frame 17- and shovel -lto the inverted position shown by full lines in Fig. 4 and while in this position it may be automatically locked and temporarily detained by the catch 42-, until the driver has returned again to the place of excavation.

What I claim is:

1. In combination with the front and rear `trucks of a vehicle, a reach-bar connecting said trucks and pivoted to the front truck, a tiltable shovel mounted upon the rear truck below the rear axle, means to tilt the shovel to and from its digging position, and a detent mounted on the rear truck and adapted to drop by gravity into holding engagement with the rear end of the shovel to prevent overturning of said shovel during the operation of loading.
