useful lmprovements in Rotatable Work-Stands, of which the following is a specification. 4

This invention relates to new and useful improvements in work stands and more particularly to the class so constructed as to be rotatable and especially adapted to beused in repair shops where engines of different types are frequently handled.

An object of this invention is the provision of a work stand, constructed chiefly of channeled iron thus producing a stand. that will prove far superior in strength to that of stands constructed of other material and at the same time producing a stand that will be by far lighter in-weight'than one constructed of solid iron bars throughout.

A further object of this invention is the provision of a work stand so constructed that it may be conveniently moved to any location desired and then substantially secured thereto.

A. further object of this invention is the provision of a work stand, having a rotatable frame so constructed to accommodate and hold thereon engines of difierent lengths and widths, and furthermore,to permit the mechanic to tilt the stand with engine on same at any angle so as to conveniently allow him to work on any part of the machine. He may completely turn the machine upsi e down while secured to the frame and wor on the underside of the engine if he so des' A still further object of this invention is the provision of a work stand so constructed that when the mechanic has completed his work of repairing the engine and is satisfled that the same is now in first-class Working order again, he may be still further assured that the same has -been properly repaired by applying the wires from the coil to the cylinders of the engine and crankcrank l[ have applied at one end of my stand, but which crank can be readily removed if desired.

It is now thought that the above objects fully bring out the fact that my workstand will eliminate the unnecemary labor now. given mechanics, owing to the fact that at the present Specification of Letters Patent.

place the engine in thecar before tesfing it after finishing repairing the same; and

furthermore when repairing the top members of the engine, should he have repairing to do on the underside also, he must undoubtedly turn the engine over, which is a laborious task, and which task is entirely eliminated by using a stand as hereinafter more fully described.

With the above and other objects in view, this invention resides in the novel features of construction, formation, combinations,

and arrangements of parts to be hereinafter more fully, described, claimed and illus trated in the accompanying drawings, in which Figure 1, is a side elevation of my rotatable' work stand, Fig. 2, is a top plan view of the same, Fig. 3, is a front elevae tionof the same, Fig. 4, is a perspective view of the foot pedals and coiiperating members secured thereto when the pedal 37 at the left is depressed, and Fig. 5, is a perspectiveview of the crank handle and plate detached.

Referring to the accompanying drawings by similar characters of reference for cor-i responding parts in all the views, the nu- -meral 10 denotes in general my rotatable ltd suitable means at their lower extremities to a longitudinal bar 14:, which holds the said standards substantially in spaced relation to each other, While secured substantially beneath this bar It at opposite ends thereof and below the standards 11 and 12 are cross bars 15 and 16 substantially braced by braces 17 and having secured to the opposite ends 111 sired, but when in the desired location, the

same maybe further braced and held substantially in the desired locafion by an angle iron 20, secured to the intermediate portion of the" cross bars 15 audit and then to the flooring. The longitudinal bar it has also secured to the intermediate portion thereofbraces 21 and 22, the outer endsnf which are secured to the standards fl and 12 by any suitable means, thus further strengthening the said standards, whilesecured to the mid braces 21 and 22 by means of'angular bolts and winged nuts 23 is a waste pan 24 adapted to catch the waste matter discharged from the frame 13, when in use.

Secured .to thejupper ends of the standards 11 and 12 by means of angular plates 25 are outwardly extended trays 26, further I ,ception'of the bolts 31,

means of bearings 28, secured to the intermediate portion of the horizontally disposed bars 29, which form part of the said frame, together with the longitudinally disposed ba rs 30. These bearings 28 are for the reoperating therein and secured tothe standards 11 and 12 by suitable means, thus it willbe readily understood thatthe said frame 13 is rotatable between the standards 11 and 12. This,

frame'13 consisting of the above mentioned bars 29 and 30 has numerous slots formed therein. The longitudinally disposed slots worked upon,

32 formed in the bars 'tion of bolts or the through 30 are for thereceplike inserted therefrom the base of the engine to be therebv producing a means for .substantially securing the said engine while the length of the slots are produced so that the said. frame. will accommodate an engine of any size and- R tlafmit the same to be adjusted thereto.

These winged nuts I apply for convenience so that It will be noted that the standard 12 is provided with a pair of foot edals 37 made of resilient material as clear y illustrated in 4 of the accompanying drawings. It

- wlll also be noted that the pedals are made substantially from one piece of material,

The standard 12 also has a slot 47 formed therein to permit the tongue 48 of the dog 45 to freely operate therethrough in order that the same may engage the teeth of the toothed wheel 49 previously mentioned and which is rotatably mounted upon the bolt 31, secured to the standard 12 and operating in the bearing 28 and gt is to be understood that the said wheel 4 rotates with the frame 13, owing to the fact that it is substantially secured to the ,bearing 28, which as before stated is secured to a member, comprising a part of the said frame. The standard 12 is also of greater length than the opposite standard 11, this extra length having apertures formed therein for the reception of bolts 49 to secure thereto an extra plate 50, also having similar apertures formed therein and also the customary auto crank handle 51 mounted therein at its upper end, the object of which vwill be hereinafter more fully described as well as that of the customary coil 52 substantially mounted on the opposite standard 11.

The. operation of my work stand is as follows :The stand is first moved to the desired location in the shop and may be substantially secured thereto, if so desired, y means of the angle irons. When in position, the engine to be worked upon, is removed from the car and placed upon the frame 13, which is at once adjustedto fit the base of the said engine, then the bolts are passed throughthe base plate of the engin'e and through the slots in the bars 30 of the frame 13 and fastened thereto by a suitable means, then the engine is in readiness to be worked upon.

The frame is always kept from rotating, when? its rotation is not desired, by the tongue '48 in contact this being due to the fact that the spring cothe said wheel, but when it is desired to turn the engine at an angle, or to turn the same completely over so as to get at the underside, the operator presses the foot pedal, which operates the releasing lever A, which in turn releases the tongue by means of the operating link 44, permitting the on, and secured thereto, to rotate between the standards 11 and 12 until in the desired erewith the toothed wheel,

ment, the operator presses the opposite foot.

pedal, which forces the tongue into positive I engagement as well as strengthens the spring considerably, while applying this pressure.

After the engine has been repaired, in order to ascertain that the same has been pro erly repaired I apply the plate carrying the crank handle to the standard 12 and forcing the same into engagement with the proper member and having the wires from the coil properly connected with. the said engine, I feed into the cylinders a suitable amount of fuel and crank the engine. Thus it will be readily seen that the engine is now in operation while on the Work stand, and should it need further repairing after this test, the same may be: done at once by merely stopping the engine, thus eliminating the extra labor produced by having to eset the engine into the car and then try it out.

ltis now thought that the above description of the operation of my work stand together with the accompanying drawings is sufiicient to give those familiar with this art a clear idea asto the operation of my device. It should be understood, however, in this connection that various minor-changes in the details of construction may be resorted to within the scope of the appended claims, without-departing from or' sacrificing any of the advantages 0 this invention.

From the foregoing disclosure taken in connection with the accompan ing v.drawings, it will bemanifest that I have provided a rotatable work stand, adapted to be used in connection with the repairing of automobile en ines or the like and which will fulfil all 0 the necessary requirements of such a device. 6
