Application filed March 10, 1920.

T a l Quiz-om mag canoe r 12 Be it known that I, Crrnsrnr. Fianna, a citizen of the United States. residing at Seattle, in the county of King and State of Washington, have invented. certain new and use ful Improvements in lVorlcHolding Stands, of which the following is a specification.

This invention relates to stands which are des'gned, more especially, for reversibly holding automobile engines or the like while being operated upon in a shop. The object of" my invention is the provision of a device of this character which will he of inexpensive, strong and durable construction. and which is adapted to be readily adjusted to accommodate various sizes of engines, and is convenient in use.

The invention consists in the novel construction arrangement and combination of parts as vill be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevational view of a stand embodving my invention shown applied.

Fig. 2 an end elevation of the same with the work and bracket supports therefor in positions reversed from where they are represented in Fig. 1.

Fig. 3 is a horizontal section through 3-3 in. l.

n l is a detail transverse sectional view of one of the bracket connections with a side member or" the stand.

5 is a sectional view taken substantially through 55 of Fig. 2, with parts broken away.

Fig. 6 is a perspective view of a rail attachment for a stand bracket.

Fist. 7 is a fragmentary elevational view of one of the side members of the stand.

According to the present invention I provide a stand having two complementary frames 10 and 10 each of substantially the shape of an isosceles triangle formed of sheet steel to provide a central web portion 11 and marginal flanges 12 at the sides and extendingover the upper angle.

To each ot the lower corners of the frame is secured as by rivets 13 the flange element 1-il ot a chambered casting: 15 through which ext nds an axle 16 for a ground wheel or roller 17.

Extending transverselv through the frame webs and the respective flanges 14: are parallel bars. such as pipes 18. which are rigidly secured to the frame 10 by nuts 19 engpecification of Letters Patent.

Serial No. 364,709.

gaging pipe threads at opposite sides of the name as shown in Figs. 3 and The pipes 18 are adjustably connected to the other frame 10 by slidablv fitting in bosses or sleeve elements 20 of the respective castings and secured by set-screws 20 for retaining toe frames at selected distances apart.

Rig-idly secured within the spaces afforded by the frame flanges 12 at the upper angle oi? the respective frames are apertured blocks. as 22 serving as hearing; boxes for screw bolts 23 and 23 which support hanger blocks 2t and 24 one to the inner side of each frame. The hanger blocl: 24 is provided with tongues or projections 25 (Fig. adapted to engage in slots 26 extending radially from the bolt receiving aperture 27 of the adjacent bearing block 22 (Fig. 7) for retaining the hanger blocks in rotary adjustments.

Such engagement of the said tongues and grooves are effected b v means of the bolt 23 and nut 28. This bolt 23 is prevented from turning by soclretinr; its polvgonal head 23 in a correspondingly shaped recess 24 provided in the associated block 22. The nut 28 for bolt 23 is desirablv provided with a lever handle 28 to facilitate the turning of the same. The nut 29 for the other bolt 23 may also be provided with a similar handle, or as shown. he of ordinary construction to be. tightened or loosened through the medium of a suitable wrench.

30 represent angle bars secured to the lower ends 2) of'the hanger blocks 24 and 24 by bolts 31 passing: through holes 32 provided on the bar flanges 30 The other bar flane'es are desirably formed with longitudinal slots -3 to accommodate bolts 34 for clamping plates 35 between which and the adjacent bar flaneies 30 the flanges as A. oi"? an engine block B mav be secured. E or operation. the stand is wheeled on its rollers 17 to the place whereat an engine block at B is to be received and which block is placed upon the bars 30 when the banner blocks 2- l-2at are pendent as shown in Figs. 2.

The work thus supported upon bars 30 is T then secured thereto with its flanges A below the clamping plates 35 by means of bolts 3 Any operations to be done upon the work, such grindi valve seats etc. which may be most conveniently performed with the the worlr upright is accomplished with the Cir work and supporting parts therefor in the positions in which they are illustrated in F 7 When the work is to be operated upon from the sides or bot-tom it may be brought into inclined or reversed positions, as inclicated in Figs. 1 and 4, by rotatably moving the same about the axes of bolts 23 and E23 and secured in selected positions by utilizing the respective nuts 28 and 29. The width or space between the work supporting bars 30 is regulated to correspond with the widths of various engine blocks by regulating the position of the frame 10 with respect to the frame 10 by first loosening set screws 21 and then moving the frame 10 longitudinally of the pipes 18 and,

finally, securing the frame 10 to said pipes by means of the set screws.

The 0 aeration and advanta es of the mvention wlll be understood from the foregoing descrlption. 7 L I lw hat I claim, is-

A worlcholding stand of the character de scribed comprising, 111 combination, a pair of frames, a pair of bars extending through the lower portions of said frames, means for securing said bars to the frames to retain the latter in different positions of ad justment; apertured bearing blocks rigid with the upper ends of said frames, one of said blocks being provided with recesses dis posed radially of the block aperture, worksupporting blocks, means for securing work thereto, bolts extending through apertures of the bearing blocks and the supporting blocks for pivotally connecting the supporting blocks to the respective frames, and a tongue provided on one of said supporting blocks and engaging in selected of the aforesaid recesses for retaining the respective supporting block in various predetermined rotary positions.

Signed at Seattle, Washington, this 1th day of March, 1920.
