Referring noiy to the letters of reference placed upon the drawings: i A denotes an adjustable horse comprising a pair of inclined legs B, B, secured togetber at their upper ends by a'divided fixtu re G, consistingof twovop posi'ng sheet metal pianes Cladapted to overlap the ends of the legs and toiem brace a normally ho'ri zontal telescoping member pi com'prising a pair of adjustable rails D ,D ,pivoted1respectively to the legs B, B, at eachend o f the horse by transverse bolt E extending through the divided fixture fitted withia w ns-nu wh eby e'pan may e sidIy" secured t getli r when P bi e y ad: justgd' M h.

other and turned between, and parallel with the legs to which they are respectively secured.

G denotes a plurality of step-fittings secured to the legs at spaced intervals, having an outstanding portion G slotted as at G to receive the ends of a telescoping member H, comprising two rails H H held in coupled relation by a sutable socket fitting H H J indicates in dotted lines one of a series of planks forming a platform resting upon the cross-members H of two horses of like construction.

The upper end of the outstanding portion G is turned at right-angles, as indicated at G to provide a step for convenience in ascending or descending from the horse.

I designates an adjustable bracket fixture adapted to receive and support a plank J". The bracket consists of a triangular shaped strap member secured to a U-shaped element 1 having a bayonet slot 1 which'is designed to engage a bolt 1 projecting from the foot brackets G, whereby it is adapted to be secured to the legs at different altitudes. The bracket has a horizontal foot portion 1 to receive a plank J and an upstanding end I, designed to overlap the edge of the plank to secure the latter against accidental dis lodgment.

K indicates a folding brace member pivoted to a lug secured to the rail D at its upper end and at its lower end there is pivoted a cross-bar K slotted at each end to receive a bolt K projecting from the walls of opposing foot bracketsthe object being to secure the inclined legs in their spread relation and to otherwise stiffen the structure when set up.

To provide means whereby the altitude of the device may be increased, suitable extension. legs L, are fitted with cross-strips L designed to enter slots L in the foot brackets Gr. When it is desired to employ the extension legs, they may be engaged to the lower ends of the legs Bas indicated in Figure 5by coupling the same with any pair of the step brackets necessary .to raise the device to the required altitude.

M denotes a connecting brace bar slotted at its ends to engage the bolts projecting from the edges of the auxiliary legs L,

In Figure 7 is shown other means for increasing the altitude of the device in which a pair of horizontal telescoping bars N, N, are supported upon the top of a pair of horses and secured against displacement by the overlapping L-shaped bracket N attached to the top of the horse and fitted with a thumb-screw N which. when adjusted serves to bind the bars rigidly to the horse. Figure 7 shows a fragment of a pair of inclined legs N N each pivoted to a U-shaped bracket N4, in turn fastened to the bars N, mounted upon the legs'B, B, of the horse A.

Having now indicated the several parts by reference letters the construction and operation of my device will be readily understood:

In setting up the horse the legs B, B, are

spread apart at their lower ends and the 1 thumb nuts E adjusted to hold the upper ends of the legs securely to the horizontal telescoping member I). The cross-bar K of the folding brace member K is then engaged with the bolts projecting from the step brackets G. The brackets I, at each end of the horse, are then adjusted to the proper altitude and secured-the bayonet slot of the U-shaped portion being engaged with the bolts I projectng from the step-brackets. The platform plank J is then laid upon the brackets T-the stepsGr integral with the brackets G forming convenient means for ascending to or from the platform.

If it is desired to raise the altitude of the horse it may be done by adding the extension legs L to the lower end of the legs of the horseas previously indicated and shown in Figure 5a connectingrod M, being engaged to the legs at their lower ends to keep them from spreading.

If desired auxiliary horses may be mounted upon bars secured to the top of the horses proper. This may be done by mounting extension bars N upon the top of the horse-securing them against dislodgment by the thumb screw N- -as clearly indicated in Figure 7. It is of course understood that the bars N are supported by a plurality of horses spaced apart.

lVhen it is desired to fold up the framing for shipment the horizontal rails 1), D are disconnected and turned so as to lie between the legs at the respective ends of the device' as indicated in Figure 8the. legs being in'turn swung contiguous to the bar D lying between them.

The wing-nut engaging the bolt E is not shown in Figures 3as indicated in Figure 2the nut being applied to the bolt on the opposite side oflegs, thus permittingthe attachment of the bracket I to the fitting C if desired.

Having folded the legs, the several ele- L, ments are secured together in the manner between the legs of the horse the cross-bar of the brace rod K is turned on its pivot parallel with the main portion of the brace, as indicated in Figure 6. \Vhen bundling the parts in their knocked down relation as indicated in Figure 4a U-shaped clip Q, is inserted so as to overlap the brace K extending between the brace and the edge of the step brackets of the respective end legsthe flan'ges Q at the ends of the clip overlapping the step brackets, as shown in dotted lines inFigure 6. The device when in.knock down form is ready for shipment or storage.

Having thus described my invention what I claim is: v 1. In a device of the character described; a normally horizontal telescoping member comprising two rails adjustable with reference to each other; neans for supporting said rails in alignment and in fixed relation to each other when adjusted; a pair oiinclined legs pivoted to the outer end of each of said telescoping rails; a plurality of divided fixtures respectively adaptedto embrace the upper ends of each pair of legs and one end of each of the telescoping rails; bolts extending through said divided fixtures to serve as pivots connecting the rails with said legs and to secure the parts in rigid relation to each other when adjusted; brackets secured to the legs at each end of the device and having studs thereon; brace members pivoted to the rails of said first named horizontal telescoping member and to cross members having slots therein to engage the studs on the brackets. I

2. In adevice of the character described including a horizontal rail and inclined legs secured thereto, a plurality of spaced brack ets on the legs having slots therein to receive the ends of an additional horizontal rail, each bracket having an ofi'set portion terminating in a horizontal flange to form steps on the legs.

3. In a device of the character described, a normally horizontal member, legs arranged in pails at the ends of the member and supporting the same, brackets mounted on the legs and arranged in horizontal alignment and having projecting supporting portions provided with recesses, and an adjustable horizontal membr having terminal portions adapted to fit in the recesses of the, horizontally aligned brackets.

4. In a device of the character described, a normally horizontal member, legs arranged in pairs at the ends of the member and supporting the same, a plurality of brackets on each leg, each having a slot therein, extensions for each leg, and a plurality of cross strips on each extension, at least two of which are received by the slots in the brackets to secure the extensions to the legs.

In testimony whereof, I signthis specification.

HARRY ROTH.
