COMBINED END-GATE AND LlFTING-dACK- Specification of Letters Patent.

Patented May 22, 1906.

Application filed January 13, 1906. Serial No. 295,974.

To all whom it may concern:

Be it known that I, ORSON BUCKLIN, a citizen of the United States, residing at Marietta, in the county of Lao qui Parle and State of Minnesota, have invented a new and useful Combined End-Gate and Lifting-Jack, of which the following is a specification.

This invention is a combined end-gate and lifting-jack, and has for its object to enable the convenient transfer of the device from one use to the other without requiring any disconnection or complicated adjustment of arts.

With this object in view the invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details maybe made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the inventi'on.

In the drawings, Figure 1 is a fragmentary perspective view of the rear end of a wagonbody having the combined end-gate and liftingjack of the present invention applied thereto. Fig. 2 is a horizontal sectlonal view taken longitudinally through the device. Fig. 3 is a side elevation of the device set for use as a lifting-jack. Fig. 4 is a detail persp ective view of the adjustable lifting-foot.

Similar numerals of reference designate corresponding parts in all of the figures of the drawings.

The present device includes end-gate sec tions or members 1 and 2 of corresponding widths and unequal lengths, which are hinged, as at 3, so as to have the joint break outwardly when an end-gate is fitted in a wagon-body, such as shown at 4 in Fig. 1 of the drawings. The end-gate sections are preferably provided with transverse cleats 5 upon their inner faces to prevent warplng thereof, while the lower edges of the members are provided with metal wear-strips 6.

Rigidly secured to the outer face of the short end-gate section is a bar 7, having a width slightly less than that of the end-gate and of a length to overlap the joint between the end-gate sections. This bar is provided with a longitudinal bifurcation 8 intersecting its free end for the reception of a swinging bolt 9, having its head loosely retained in a socket 10, formed in the end-gate, and its outer end carrying a handled nut 11 and bearing against the outer face of the bar 7, thereby rigidly interlocking the elements of the end-gate when the latter is in use, as illustrated in Fig. 1 of the drawings. Suitable metal lates 12 are provided upon the outer face 0 the bar 7 at opposite sides of thebi- 'furcation 8 to take the wear of the nut 1 1.

To enable the use of the device as a liftingjack, a metallic lifting-bar 13 is mounted in the bifurcation 8, with its inner end pivoted, as at 14,'t0 a flange 15 upon a metallic arm 16, secured to the outer face of the member 2 at its inner end. The free end of the lifting-bar works between guide-

straps

17 and 18, secured to the opposite faces of the bar 7, the guide 17 having an intermediate offset 19 to permit of the necessary tilting movement of the lifting-bar. The front or outer edge of the lifting-bar is smooth, and its rear edge is toothed, as at 20. A lifting-foot 21 has its inner end bifurcated, as at 21, (best shown in Fig. 4 of the drawings,) whereby the foot straddles-the lifting-bar. This foot has longitudinal upstanding flanges 22 at its opposite sides, and a transverse pin 23 pierces the rear portions of the flanges in rear of the lifting-bar, so as to engage the teeth. When the pin 23 engages the back of the lifting-bar and the inner closed end of the bifurcation engages the front of the lifting-bar, the foot 21 will be held upon the lifting-bar at substantially right angles thereto and projecting forwardly through the bifurcation 8. The upper edges of the flanges 22 are toothed or serrated, as at 24, to prevent slipping thereof upon an axle, and there is a transverse upstanding flange 25 at the outer end of tie foot, the outer edge of the flange being sharp or beveled and terminating short of the tops of the flanges 22.

When using the end-gate as a lifting-jack, it is removed. from the wagon and stood in an upright position upon the section 1 as' a standard. The foot 21 is adjusted upon the lifting-bar 13 to engage the under side of the member to be lifted, whereupon the section 2 is swung downwardly as a lever, thereby lifting the bar 13, the foot 21, and the member with which the foot is en aged. When the member 2 has been swung down past the horizontal and into engagement with the ground or floor, the lever and lifing-bar are locked and the member to be jacked up will be supported in an elevated osition. It will here be explained that the anges of the foot produce a trough or receptacle to receive such lubricant as may run off of the axle-spindle, particularly when the foot is disposed longitudinally of the spindle at its outer end. When disposed in this relation, the wheel may be drawn from the spindle onto the foot 21, where it will be supported while the spindle is being lubricated, and the wheel may afterward be slipped back upon the spindle in a prompt and positive manner.

In connection with the use of the device as an end-gate it will be noted that the liftingbar folds into the bifurcation 8, and the foot 21 is capable of being folded upon the liftingbar so as to embrace the same, said bar being provided with a transverse notch 26 in its front edge to receive the flange or lip 25 of the foot, whereby the latter is permitted to fold in flat against the lifting-bar.

When the device is used as a lifting-jack, with the foot 21 disposed longitudinally of an axle, the hub-attaching nut is first removed and then the foot is adjusted so that the lip 25 engages the under side of the small nut on the endof the skein, the lip biting into the nut, so as to prevent slipping thereof, while the flanges 22 embrace the nut and prevent turning thereof. Ordinarily the jack will be applied to the end of a spindle with the foot 21 in longitudinal alinement therewith, as hereinbefore described, and will be employed with the foot under the axle at substantially right angles thereto only when it becomes necessary to remove the wheel entirely from the spindle for the purpose of cleaning the same.
