Patented Oct. 3, 1950 WAGON-BOX ELEVATING AND TILTING DEVICE Clark F. Walsh, Charles City, Iowa Application December 29, 1945, Serial No. 638,341

The present invention relates generally to a novel and improved wagon box elevating and tilting device, but more particularly to a simple and improved construction adapted to be attached to the conventional type of farm wagon so that the front end of the box carried thereon may be elevated to the desired height to dispense or discharge substantially-the complete contents therefrom by gravitation. i

A further object of the invention is to provide a novel and improved construction of a, wagon box elevating and tilting device in combination with a conventional type of hydraulic jack or lift so that the jack thereof may be easily and quickly attached thereto ordet ached therefrom so that the same may be used in connection with successively elevating and tilting any number of wagon boxes. which are suitably equipped to support the jack thereon.

A still further object of the invention is to provide a novel and improved. telescoping arrangement for supporting therein a conventional post type hydraulic jack and means whereby the jack may pivot and be adjusted with respect to the wagon box so as to support, elevate and tilt the front end of the wagon box for discharging the contents therefrom.

These and other objects are accomplished by providing a construction and an arrangement of the various parts in the manner hereinafter described and particularly pointed out in the appended claims. I I

Referring to the drawings:

Fig. 2 is a similar side elevational view showing the manner in which the wagon box is partially tilted b raising the front end thereof;

Fig. 3 is a fragmentary top plan view showing the construction for supporting the jack thereon, with the jack removed; a

Fig. 4 is a cross sectional view taken on the line :ll in Fig. 1;

Fig. 5 is a fragmentary front elevational view showing the wagon box and jack in its lower most position; and i Fig. 6 is an enlarged longitudinal cross sectional view showing the manner in which the post type hydraulic jack istelescopica-lly mounted in the sleeve-like socket.

In illustrating one form of my invention, I have shown the same in connection with a conventional form of farm wagon which comprises 8 Claims. (01. 298-19) supporting wheels I t and 1!, suitable axles therefor and a connecting .briefiy, front and rear reach !2 between the front and rear axles. The front axle portion of the wagon is provided with the usual transverse bolster or beam 13 to which isv secured the usual forwardly projecting and horizontally spaced stub-tongue members M. Supported on the wagon frame in the manner well understood in the art, is a wagon box generally indicated by the reference character H: which consists of a bottom l6, side walls I! and front and rear end gates l3 and I9. Secured to the lower surface of the floor it of the Wagon box adjacent the forward end is the usual transverse cleat 2il.

My improved unit which is adapted to support a hydraulic lift or jack therein and which may be mounted on any type'of conventional farm wagon, comprises a transverse wood beam 2! which is adapted to be mounted on and clamped to the transverse beam It by means of clamp brackets 22 and clamping bolts 23. Secured to the underside of the transverse beam 2! is a forwardly projecting member or plate 24. Secured to the opposite edges of the forward portion of the plate 24 are spaced apart vertical walls 25 forming a channel-like arrangement at the front end thereof. Mounted in a threaded aperture 28 at the forward end of the plate 2 5 is a threaded bolt 21. The upper end of the bolt '2'! has a hand grip 29. The lower end of the bolt is provided with annular recess and upset head 3| so as to swivelly engage a transverse channel member 30. From the above description it will be readily seen that by adjusting the hand screw 29, the forward end of the plate 24 may be raised or lowered with respect to the transverse channel member for tilting the position of the hydraulic jack in adjusting the same with respect to the front end of the Wagon box. It will also be noted that the transverse channel member 39 rests upon the opposite-stub tongue member l4 and is free to slide with respect thereto as well as pivot about the lower end of the bolt 2? when the front wheels iii are turned with respect to the frame of the wagon. The pivotal movement of the transverse member 38 is limited by means of upwardly and vertically extending pins or bolts 32 which have their lower ends mounted in suitable threaded apertures in the member 3!]. As the member 39 swivels about the lower end of the bolt 21, these pins are adapted to engage the vertical sides 25 of the plate 213 in the turning movement. Pivotally mounted between and to the opposite sides 25 of the channel member is a vertically extending socket or pipe 33. The pipe 33 is pivoted to the side wall members by means of a transverse bolt 34 which extends through a tubular member 35 mounted in the diametral opening 36 in the sleeve 33. Secured to the forward end of the wagon box and embracing the lower side and forward edge of the transverse cleat 20 is a reinforcing angle member 31. Extending through the wagon bottom It, the c1eat'20 and the lower flange of the angle member 31 is an eye-bolt 38 which forms the connection for a hook of a link connection 39 to the jack in the manner hereinafter described.

The units or parts thus far described are adaptable to be mounted on any conventional type of farm wagon so as to form the supporting structure which will permit a conventional hydraulic jack, generally indicated by the reference character 40, to be removably supported therein for elevating the front end of the wagon box for discharging the contents thereof from the rear end. This arrangement permits the jack to be easily moved from one wagon to another when they are equipped with the same apparatus to support and accommodate this jack.

The hydraulic post-type jack, as indicated at 40, is of the conventional type, but is preferably of the form disclosed in the L. C. Nilson patent, No. Re. 21,112, granted June 3, 1939. For further details of the construction and operation of this jack, reference to that patent may be had.

The jack 40 comprises briefly, a vertically reciprocatable sleeve-like hand operating member H which, in turn, elevates a sleeve 42 on a shaftlike member 33. The shaft-like member has its lower end adapted to rest upon the transverse tubular member 35 and bolt 34. Secured to the lower end of the sleeve member 42 is a collar 44 which is adapted to reciprocate or move within the inner bore 45 of a telescoping sleeve 46 which, in turn, is telescopically and removably mounted in the socket 33. When the sleeve 42 attains a certain height, the collar 44 secured on the lower edge thereof engages a shoulder or internal flange 41 formed on the upper end of the telescoping sleeve 46. Secured to the intermediate portion of the tubular member 42 is an adjustable clamp bracket 48 which may be adjustable vertically and securely clamped by a clamping screw 49. Formed on the rear side of the bracket 48 is a hook 511 to which the eye 5| of the link connection 39 may be attached.

Summarizing the advantages and function of operation of my improved wagon box elevating and tilting device, it will be readily seen that by providing or equipping each conventional wagon with a socket or sleeve 33, together with th necessary attachments for supporting it in position,

it is then possible to quickly detach or attach the post-type hydraulic jack 49 from one wagon to another, thereby obviating the necessity of having more than one jack for performing the function of discharging the contents from each wagon box and by providing an adjustment so that the jack socket 33 may be adjusted vertically to accommodate the jack M] with respect to the box. This novel arrangement provides a very simple and efficient means for this purpose at a .minimum cost. If an operator desires to raise the box to an elevation higher than that shown in Fig. 2, suitable blocks or supports may temporarily support the raised box while the lower end of the hook link 39 may then be transferred to a suitable aperture provided in the lower flange of the transverse angle member 31 to elevate the box an 4 additional distance from that shown in Fig. 2 of the drawings. In this connection it will also be noted that the upper end of the sleeve 33 is beveled or tapered as shown at 33' so as to permit the forward edge of the angle member 31 to freely slide thereover in the operation of lowering the front end of the wagon box.

While in the above specification I have described one embodiment which my invention may assume in practice, it will of course, be understood that the same is capable of modification and that modification may be made without departing from the spirit and scope of the invention as expressed in the following claims.
