COLLASBLE Application filed August 27, 1924. Serial No. 734.395.

This invention -which relates to a horse for supporting' loads, is concerned particularly with Vcertain features of construction by i y 1 f I winch the device may be folded up tor shipment, storage, etc.; by which 1t may be readily adjusted to different heights, desired; by which its several components may be produced conveniently .from bars, plates, etc.,A

of standard formation; and by which such components may be assembled into a unitary structure having the necessary strength for sustaining heavy loads. Certain exemplifications of my invention in a preferred form are shown in the accompanying drawings in the manner following F ignre `l is a side elevation of the horse erected;

As shown. in thev drawings the major elements of the present horse include a pairV oflegs A and B at one end and a similar pair of legs A and B at the opposite end of the device. rFliese two pairs of legs provide support, respectively, for adjustable uprights C and C between which is extended a load carrying bar D. For convenience and economy in construct-ion and assembly, these several major elements n ay be specially formed in the manner which will now be explained.

According to the exempliflcation shown in Figs. 1 to 8 inclusive, each ofthe four legs is made of angle iron. At the upper end .of each leg is a reinforcing angle piece l5, also of angle iron, and connected therewith as by rivets 16 to provide a channel formation. Each pair of legsis confined at its upper end between a pair of bracket plates 17 with the aid of pivot pins l8,.one foreach leg, each pin passing through-.the two plates, two angle irons, land a spacing sleeve .19, as shown, to `provide a hingedconnection. An addition-al connection between each leg and the bracket plates is also pro.- vided, and this may consist of a pin -20 which extends through a` slot 2l, ,one `in each plate, as well as through the legVreinforcing irons, and spacing sleeve 22 in such a. manner as to having a sliding movement within these slots; Bythe means described, the swinging movement of V each leg is stopped definitely when the pin 2O abuts one end of the slot 2l. As shown. eachzof the two bracket plates. may be inwardly flanged as at 23 along its opposite sides which are tapered in conformity with the outermost position which the .legsare lpermitted to assume. These flanges are adapted to serve as lan additional means for limiting` the outward movement-of thelegs. Y

Between each pair of legs in their lower region is a toggle connection compressing Va pair of links 2e pivoted to each other at 25 and tothe legs atV 26. Abutting shoulders 27 are formed at the rmeetirng ends oit these links (-see Fig. 3)- adapted to .engage with each other only when the 4links have been moved slightly beyond lthe' line of the v:two pivots 26. lt is Vp-referred that the-stop means should so limit the movement of each pair of legs 'that the-toggle linl's vmay be brought to'iinalposit-ion only with the application of an appreciable force, .the result being that these'linlrs will thereby normally be held against return movement.

Each pair of bracket plates provides .support between the legs connected thereto for a guide member here shown as atube having, by preference asquare cross section. These tubes are adapted to receive the two adjustable uprights C. each of which may conveniently be formed of a pair of channel bars 29 arranged baclr to back and united by rivets 30, as shown in Fig. 7 Ait-intervals the ilanges of these uprights are notched as at 8l in such a manner as to receive the upper ends of the legs, each of `which engages within two notches (see Fig. 6), to

provide a secure support for the uprights. rlhe position of vertical adjustment ot these uprights can quickly be changed but only by lirst breaking the toggle connection 24 and then folding the legs inwardly a sul'ricient distance to remove their extremities from the notches. In any ot' its adjusted positions, the guide tubes 2S add such lateral support to the uprights as may be required.

The load supporting bar D is connected with the upper end ot each upright as through the medium ot a gusset plate 32 which may be secured ixedly between the two channel bars Q9 as by rivets 33 (see Fig. 5). Each gusset plate is also extended between a pair of angle irons 34 which together may form the load supporting bar D. A pivotal connection 35 is provided between each gusset plate and the supporting bar D such as to permit of each pair ot' legs being folded inwardly to the position shown in Fig. 2. 'Io lock the legs against'any such movement when the horse is erected, I provide two pins 36 adapted to enter openings 37 and 38 in the supporting bar and gusset plates7 respectively, each pin being shown as attached to a chain 39 having a connection with a lined part of the device. To further make secure and rigid the structure heretofore described, I may also equip each upright C at its lower end with a bracket member 40 to which is pivotally joined a pair of arms il and Ll2 having a detachable connection with the load supporting bar as at 43 and 44, respectively.

The horse shown in Figs. 9 to l2 inclusive which is both 'oldable and adjustable, follows in general the construction already described. Accordingly the preceding reference numerals have been reproduced wherever applicable to the corresponding parts of this modilied structure.

As suggestive of certain changes which I contemplate as within the scope ot this invention, each pair of legs is shown as connected to a single bracket plate 17, and the upright bar C as beinfr formed from a pair ot' angle irons 29. ll eans tor guiding the movements ot each upright is provided by forming the bracket plate with a channel wherein is received two of the abutting ianges of the upright components. In ad dition, a pin 51 may provide a temporary support tor each upright preliminary to proper engagement ot the upper ends et the several legs within the notches hereinbefore described. Instead of providing rigidity to the structure by the use ot arms which connect the load supporting bar D with each bracket plate, I have shown a toggle connection consisting of a pair ot' pivoted links 52 one connected to the supporting bar as at 53 and t-he other to the upright as at 54. In such a construction it is unnecessary to provide several points ot' connection between the links and the load supporting bar, inasmuch as the distance between the two pivots 53 and 54 remains constant irrespective oi vertical adjustments which are etiected. the same manner as the one previously described, and hence has all the advantages oi being compact and easily handled when not in use.

The forms which my invention may take are many, but the structures herein shown and described are representative of two which are particularly advantageous. Besides having the necessary strength for sustaining a heavy load, the several parts are so arranged and connected so as to rein- Atorce the structure as a whole, and to remain set in extended position when the device is erected for use.

I claim:

l. A horse in which is comprised a load supporting bar, a pair otI` uprights hinged thereto, and each oldable toward the other, a guide wherein the upright is slidably mounted, a bracket to which the guide is secured, a pair of legs swingingly connected to the bracket and adapted, when distended. to engage with the upright to hold the same in a given position ot adjustment, and a detachable connection between each upright and the load supporting bar adapted to prevent folding ot the legs, with respect thereto, substantially as described.

2. A horse in which is comprised a load supporting bar, a pair of uprights hinged thereto and each t'oldable toward the other, each upright comprising two united bars having oppositely extended edges wherein are formed notches, and a support for cach upright consisting of a pair ot legs toldable toward and troni each other and adapted, when distended, to engage with certain ot' the notches o'' the upright whereby the latter is supported positively in a selected position ot adjustment, substantially as described.
