ENGINE-RACK.

iacaeea.

To all 'whom z't 'may concern Be it known that I, CARL REISELT, a citi- '/.en of the United States, residing at Oblong,

in the county of Crawford and State ofl Illinois, have invented certain new and useful Improvements in Engine-Racks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as lwill enable others skilled in the art to which it appertains 4to make and use the same.

This invention relates to metal working, and more especially to work holders; and the object of the same is to redu'ce a machinists rack for holding internal combustion engines while being cleaned, adjusted, or repaired.

Specific objects of the invention are to provide a specially adjustable cross bar within the rack-frame, and a peculiarv form of operating handle and latch therefor. A description of my invention as now made will be found in the following specification, reference being had to the drawings wherein- Figure 1 is a perspective view of this im proved rack with an engine therein. Fig. 2 is a plan view o f the rack complete, with the handle swung outward to a horizontalposition. Fig. 3 is a cross section through the frame and an edge view of the cross bar. Fig. 4l is a perspective detail of one of the clips at the extremities of the cross bar.

rIhe base or framework of this improved machine may be made of stout metal bars, although I prefer tubing as shown. and it includes two duplicate end pieces. Each has a head 1 from which legs 2 diverge downwardly and are preferably bent at 3 and then carried straight downward into feet 4 having casters 5 so that the rack can be moved over the floor or other support; and the legs are connected by side bars 6 whose extremities may well form Ts 7 embracing the legs and held thereon by set screws 8. 'Ihese side bars hold the end frames upright and rigidly spaced, and may be set lower than shown when a large engine is to be mounted in the rack and the frame will be widened as then required. Disposed within the upper portion of this base is a frame best seen in Fig. 2. It comprises two cross heads 10 each having a stub shaft 11 j ournaled in one of the heads 1, two side bars 12 preferably having inturned ends 13 slotted as at 14:, and bolts 15 passing through said slots and through similar Speecation of Letters Patent.

slots 16 in the cross heads. By this means the side bars can be adjusted inward or outward from an axial line through the two stub shafts, which latter support the frame \rotatably within the base. The engine shown in Fig. 1 comprises a casting C having lateral ears E, and a fly wheel F, but this rack is adapted/to almost any type of engine. rllhe ears are laid over the side bars 12, and clips 18 are employed to fasten them thereto. In most forms of engines there are ears E at one end ofthe casting C, but the other end thereof must be supported in some manner by a rack ofthis character, and the form of the rack must be such as to adapt it to the various types of engines.

Referring now to Figs. 3 and 4, it will be seen in the last named View that I provide two U-shaped clips 20, each adapted to pass over one of the side bars 12 and having a bolt 21 passing through the outer arm which is short and through the inner arm which is long and has a slot 22. Next inside these clips are L-shaped brackets 23 having their arms slotted, and their upright arms are secured to the longer arms of the clips by said bolts and by other bolts .24 whereby the brackets may be adjusted vertically. Overlyingthe horizontal upper arms of the brackets is a cross bar 25 having slots 26 near its ends. and bolts 27 pass through these slots and through those in the upper arms of the brackets whereby the latter may be adjusted horizontally with respect to the cross bar. The center of the latter is provided with a slot 28 through which may be passed a bolt or a clevis 29 by means of which the engine is attached to the center of this cross bar. This construction permits the latter to be lengthened or shortened as the side bars of the frame are adjusted outward or inward to increase or to reduce its width, and it permits the cross bar to be adjusted vertically so that its fastening devices may be brought into proper relation with the engine for convenient attachment thereto. It is of course possible to disconnect and invert the L-shaped brackets, which would place the cross bar 25 at their lower ends instead of their upper ends as shown at Fig. 3. vIt is also possible to invert the U- shaped clips 2O so that the cross bar will stand yet lower. Finally, it is possible to loosen the bolts and adjust said clips 20 and the cross bar longitudinally on the side bars 12. These various possibilities render the disposition of the cross bar and its fastening devices adjustable in all directions, or even removable entirely, and therefore the rack is adapted to various types of engines. When an extremely large engine is secured within the frame, it may be advisable to loos'en the set screws 8 and adjust the side bars 6 to lower positions on the legs 2, but ordinarily I would have them stand as high as convenient so as to thoroughly brace the base.

One of the stub shafts is continued through its bearing and provided on its outer end with a fork as shown at 30, and pivoted within this fork is l-a knuckle 31. Swiveled at 32 in the outer end of the knuckle is a handle 33 which normally hangs from the pivot of the fork but which may be swung outward or upward, and its lower end is cranked to produce a hand piece 34. A notched rack 35 connects the legs 2 at this end of the machine, and the handle hangs normally just outside its notches. Loosely Amounted on the handle which is preferably round) is a button 36 having one end turned down into a foot 37. When this button is raised it may be revolved freely on the handle, but When the latter is swunginto engagement with the toothed rack, the button maybe turned so that its foot passes over behind the rack, and then it can be dropped yinto engagement therewith to prevent thedisengagement of the handle from the notches.

In the use of this device, the frame is adjusted in width and the cross bar 25 in position to t the engine which is to be worked on, and the engine is then put into the frame, rested upon the cross bar, and bolted or clipped to these elements With its center of gravity as nearly as possible coincident with an axial line through the stub shafts. parts now stand as seen in Fig. 1, and the workman has convenient access to the upper side of the engine. When he desires to reverse it, he lifts the button and turns its foot lout of engagement with the rack 35, then grasps the hand piece 34 and pulls it forward slightly, then raises the handleto a horizontal position as seen in Fig. 2 and to an upright position, turning the handle in its swivel 32 so that the hand piece projects outward; and then by giving the entire handle a half revolution he can turn thev frame and with it the engine so that the .latter stands in an inverted position, after which the handle is rengaged with the rack and the button dropped into place to hold it. The rack will have several notches The j tions within the shop.

What I claim is: 1. In an engine rack, the combination with a base, a frame whose end bars have stub shafts journaled in said base and whose side bars are laterally adjustable with respect to said end bars, and means .for turning lthe frame on its trunnions and holding it in varlous positions; of U-shaped clips adjustably mounted on the side bars of the frame and each having one short arm and one long armrovided with a slot, a cross bar within the rame having its ends longitudinally slotted, L-shaped brackets having their arms slotted and lapping the ends of said cross bar and the longer arms of the clips, and bolts through all registering slots.

2. In an engine rack, the combination with a base comprising two end pieces connected by side bars and having bearings through their heads, and a frame disposed between said end pieces and having trunnions mounted in said bearings, one trunnion having a fork at its outer end; of a handle pivotally mounted in said fork, a rack on the adjacent end piece with which the handle may be engaged, and a button rotatably mounted on the handle and having a foot adapted to drop behind said rack, for the purpose set forth.

3. In an engine rack, the combination with a base comprising two end pieces connected by side bars and having bearings through their heads, and al frame disposed between said end pieces and having trunnions mounted in said bearings, one trunnion having a fork at its outer end; of a knuckle pivotally mounted in said fork, a round handle swiveled at its inner end in said knuckle and having its outer end turned at right angles into a hand piece, a rack carried by this end of the base and standing just inside the pendant position of said handle, and a button rotatably mounted on the latter and having a down-turned foot for engaging behind the rack, for the purpose set forth.

In testimony whereof I aiix my signature in presence of two witnesses.
