GEORGE S. WASHBURN, 0F BELLE PLAINE, IOWA.

BACK FOB VEHICLES.

To all whom it may concern Be it known that I. Gnoncn S. WASH- BURN, a citizen of the United States, residing at Belle Plaine, in the county of Benton and State of Iowa, have invented a certain new and useful Rack for Vehicles, of which the following is a specification.

The object of my invention is to provide a rack for vehicles of simple, durable and inexpensive construction provided with uprights pivotally mounted at its ends and adapted to be swung from upright to de pending position for moving the rack from the running gear of a wagon and supporting it after it has been so removed in proper position for placing the running gear under the rack in suitable position for again mounting the rack on the running gear.

More particularly, it is my object to provide in such a rack side rack members pivoted to the upright members and to provide new and novel means for mounting said side rack members on the frame of the rack near the middle thereof and for locking said side'members in position for holding the end members upright and also for permitting the movement of said side members when the end members are swung downwardly or upwardly.

My invention consists in certain details, in the construction. arrangement and combination of the various parts of the device, whereby the obiects contemplated are at tained. as hereinafter more fully set forth, pointed out in my claims. and illustrated in the accompanying drawings. in which:

Figure 1 shows a side elevation of a rack embodying my invention. the dotted lines showing the positions of the end members when lowered for supporting the rack on the ground and showing a wagon running gear beneath the rack. Fig. 2 shows a top or plan view of the rack. Fig. 3 shows a detail view of the catch device. and Fig. 1

shows a detail. sectional view ofoneof the brackets and the cross member. between the upright members.

In the accompanying drawings, I have used the reference numeral 10 to indicate the ma n long tudinal f ame members of a rack. Mounted above the frame mem ers 10 are transverse members 11 extending laterally beyond the framev members .10. Resting upon the frame members 11 are the Mounted on the frame members 10 near Specification of Letters Patent.

Application filed March 28, 1914;. Serial No. 828,092.

their ends are brackets 13 comprising angle irons having the central portion of one angle cut away, and the other angle bent U-shaped. as shown in Fig. 4 to form a bearing 14. There are at least two of the brackets 13 at each end of the rack and the bearings 14 of the brackets at each end of the rack are arranged in alinement.

Mounted in the bearings 14 at each end of the rack is a transverse connecting member 15. Formed on the member 15 at the forward end of the rack at each end thereof is a normally upright rack member 16 preferably of hollow tubing. Formed on the ends of the member 15 at the rear end of the rack are normally upright rack members 17 also preferably formed with hollow tubing. Telescopically received within the members 16 and 17 are members 18.

It will be seen that by varying the distance which the members 18 are inserted into the members 16 and 17 the total length of the upright frame members may be considerably varied. It will also be seen that the members 17 and 15 and the members 16 and 15 form U-sha ed devices which may be swung around from position where the members 16 and 17 are upright to the position where they extend. downwardly from the main frame of the rack, as shown by the do ted lines in Fig. 1.

v Pivotallv secured to each of the members 16 preferably near the outer ends thereof is .a s de rack member 19 normally extending downwardly and approximately to the trans erse center line of the rack, as shown in Fig. 1. Similar side frame members 20 are similarly connected with the member 17 and extend downwardly and approximately to the transverse center line of the rack on each side thereof.

I have provided the following means for suitably mounting the lower ends of the members 19 and 20 on the side of the rack near the transverse middle line thereof. Secured to each of the members 19 and 20 near its lower end is a bolt 21 formed on and extending from whichis a catch device 22'. Pivotally mounted on the outer members 12 at each side of the rack are a plu ralitv of pairs of bars 23. Assuming that the bars are in the position shown in Fig. 2, which is the position they have when the members 16 and 17 are upright they extend forwardly parallel with the members 12 and have formed at their forward ends extensions 24 extending forwardly and. out wardly as clearly shown in said Fig. 2. The catch devices 22 are pivoted between the free ends of the extensions 24: by means of bolts 25. It will be seen that each of the members 19 and 20 is connected with one of the members 12 in the same way. Mounted on the sides of the members 12 in suitable position are coacting catch devices designed to engage the catch devices 22 when the members 17 and 16 are in their upright positions. These coacting catch devices comprise plates 26 secured to the sides of the members 12 by bolts 27 or the like.

Formed on the plates 26 are horizontal extensions 27 extending outwardly away from the members 12. Formed on the outer ends of the members 27"* are horizontal extensions 28 parallel with the mem ers 12. Formed on the ends of the members 28 farthest from the ortions 27 are portions 29 inclined outwardly and away from the members 28. These coacting catch devices are made of strong resilient material;

In the practical operation of my improved device, assuming that the parts are in the position shown in Fig. 1, with the members 17 and 16 upright and the members 22 engaged by the coacting catch devices, the rack is. in position for use.

Assuming that the rack is on a wagon 7 running gear and it is desired to remove it therefrom, the driver may press against the members 29 and on account of the resiliency of said' coacting catch devices they may be pressed away from the members 22, thereby releasing the members 22-. Thereupon the members 23 may be permitted to swing outwardly and rearwardly. The members 16 and 17 may then be swung rearwardly and downwardly until their ends extend downwardly and rest upon the ground, thereupon the vehicle can be backed a short distance.

Assuming that the members 17 and 16 and the members 18 are of such total length that when they are in a vertical, downwardly extending position, they hold the rack members 10 above the position which the rack members have on therunning gears, it will be seen that by backing the wagon the rack' will be elevated. The height to which the rack will be elevated depends upon the combined length of the members 17 and 16 with the members 18. When the members 16 and 17 reach vertical downwardly extending positions the members 23 will be returned to their original position and the catch devices may be locked. The rack will thereupon be supported upon the members 16; and 17 and the members 18 and the wagon running gear may be pulled away.

-.l7Vlien it is desired to replace the rack on the running gear the running gear is run below the rack and the rack maybe lowered upon it. The advantages of such a rack are largely obvious from the foregoing description. It may be readily and easily removed from, or placed on the running gear of a wagon by one man and without any heavy elevating strain. The parts 23 and 2 k and the coacting catch devices are of simple and effective construction,the coacting catch devices being so constructed that the member 22 engages the member 29 and springs it to position for causing the two catch devices to engage automatically when the members 23 and 2 1 are moved toward the middle of the rack. It will be seen'that the distance between the member 28 and the member 12 is approximately the same as the distance from the line of the engaging edge of the catch member 22 to the portion of said member 22 which engages the member 12 when the catch devices are locked. The engaging edge of the member 22, when said catch devices are locked stands against and parallel with the member 28 and fits close up to the member 27 sothat the lateral pull of the member 22 and the arm 20 or 19, as the case may be, is imposed on the member 28 close to the member 27*.

It will be understood that the members 20- and 1-9 are mounted on the members 17 and 16 loosely enough to permit slight lat-- eral swinging of said arms 20 and 19, as illustrated by the dotted lines in said Fig. 2.

On account of the use of the plates or links 23, the arms 20 and 19 are always con- 7 nected with the frame of the rack and it is unnecessary to provide means for clamping or fastening them on the rack. In other words, all the adjustments of the rack may be made without the necessity ofdetaching any parts from the rack.

On account of the fact that the links or plates 23 are made in parallel pairs receiving the members 22 between their ends, and receiving the members 12 between. them when the engaging devices are locked together, it will be seen that said links or plates hold the arms 19 and 20 against movement in av vertical plane.

It will be understood that changes may be made in the details of the construction of my rack without departing from its essential features and it is my intention to: cover by this application any such changes which may be included within the scope of the following claims. V 1
