J. H. STALEY ENGINE AS 5 EMBLY TABLE Filed Mar. 1, 1921 Patented Feb. 1923.

JOSEPH H. STALEY, 0F COLUMBUS, INDIANA.

ENGINE-ASSEMBLY TABLE.

Application filed March 1,

To (ZZZ whom it may concern:

Be it known that I, Josnrn STALEY, a citizen of the United States, residing at Columbus, in the county of Bartholomew and State of Indiana, have invented new and useful improvements in Engine-Assem bly Tables, of which the following is a specification.

This invention relates to tables for holding engine blocks rigidly in either vertical or horizontal position during the initial assembly of its appurtenances or repair afterwards, and the object is to provide means for quickly and securely locking the engine bed in place, and to provide foot-operated means for unlocking the table to allow the table to be rotated to bring different parts within convenientaccess of the workman as his work progresses.

A further object is to provide a more eflicient and convenient holder for tools whereby work on the parts is facilitated.

still further object is to provide a deviceof the above character which is simple and cheap to manufacture, strong and durable, and effective in operation.

()ther objects and advantages to be derived from the use of my invention will appear from the following description and claims, taken with the accompanying drawing, in which Fig. l is a top plan view of my invention with the engine blocks removed. .Fig. 2 is a perspective view of samewith an engine lock in vertical position and another in horizontal position clamped thereto. Fig. 3, is a vertical section on the line 3-3 of Fig. 1. Fig. 4.- isa section on the line 4-4 of Fig. 1., and Fig. 5 is a section on the line 55 of Fig. 1.

Like characters of reference indicate like parts in the several views of the drawing.

The base 6 and standard 7 are of integral cast iron with holes through the base for bolting same firmly to the shop floor. The: top of the standard terminates with a horizontal plate 9 upon which the table 8 is pivotally mounted, and surrounding the pivot in both table and plate is a circular ball race in which ball bearings 9 are mounted, the lower half of the race being in the plate 9 and the upper half being in a circular concentric portion 10. The portion 10 has radial teeth which are engaged by a dog;

11, vertically mounted in a bracket extension 12 from the standard, and pressed normally upward by a spring 18. A stem 14 of the dog is pivotally secured to a foot lever. 15 whlch is pivotedfto cars at the junction of the standard with the base. When the dog is withdrawn by a pressure of the workmans foot the table is free to be rotated by hand and will be easily moved by reason of the ball bearings 011 which it is mounted.

Integral with the face of the table 8 adjacent a straight edge thereof are the

upstanding lugs

16, 16, and inwardly of the table therefrom a distance suiiicient to receive between them, the widest engine block are the like pair of lugs 17, 17. .When narrower engine blocks are placed the unoccupied space between it and the lugs is built out with furniture and wedges in the usual manner. Passing through the table adjacent the lugs 16, 17, are screws 18, for levelling the block before it is clamped tight. Opposite each end "of the rectangle marked by the lugs 16, 17, are the blocks'19 which are integral with the table and have a dowel pin 2) at their upper ends to enter a corresponding socket in the end of a clamp bar 20, having a middle opening in which the eye ofan eyebolt 21 is pivoted. The bolt extends through a hole in the table and through a threaded hole in a hand wheel 22 which bears against the under side of the table. The inner end of the bar 20 is adapted to bear upon an offset portion of the engine block, such as the offset for the water jacket, and clamp the block to the table by tightening the hand wheel on the eyebolt. v

The above described means is that provided for securing an invertedengine block to the table 8, and on the other side of the table I provide the following means for securing' a block in a horizontal position. This comprises a pair of secured to the table in an adjustable manner by bolts 24 passing through slots 25. Inwa-rdly of the table are the

ribs

26, 26, one or the other of which will take the engine flange, in the manner shown in Fig. l, to concentrate the bearing area under aclamp bar 27. The latter hasv a middle hole for a bolt 28 which passes through a hole in the table 8 and has its threaded end received by a screw wheel 29. The opposite end of the bar 27 rests upon a cam on a rock shaft 30

blocks

23, 23, preferably mounted between suit-able ears on the table. The shaft is rocked by a hand lever extension 31.

Slots

32 and 33 are formed through the table 8 to receive the Workmans tools which are hung therein by passing their handles or other convenient and suitable portions therethrough.

The manner of using my invention so apparent from What has been said when read in connection with the drawing, that further description and explanation deemed unnecessary.

Having thus fully described my invention, What I claim as new and Wish to secure by Letters Patent oi? the United States, is

1. a inc-assembly machine, a table, double row of projections thereon receiving the engine block between them, means operated from below the table to level the block, and clamp-means at three points to retain the block in a given position,

2. In an engine-assembly machine, a table, adjustable means thereon to prevent displacement of the outer port-ion of an engineblock placed on its side on the table, a clamp plate to force the inner portion oi the block toward the table, and a rocking-cam operating against the plate to tighten it against the block.

3. In an engine-assembly machine, a table, adjustable block-means thereon to prevent lateral displacement of the outer portion of an engine-block placed on its side on the table, and cam operated clamp-means in- Wardly of the table to engage the block midway of its ends and lock the block to the table.

4;. In an engine-assembly machine, a table,

dj'ustable block-means thereon to prevent lateral displacement of the outer portion of an engine-block placed between them, and a clamp means to lock the block to the table comprising aplate, adjustable means for connecting the plate with the table, and a lever-operated rock-shaft With a cam to 1'' 'se one end of the plate and lower the other end into contact 'ith the'bloch.

5. In an oneinc-assembly machine, a table, plnr: i'ty of lugs in a double row between which brlC engine-block is placed, set screws through the table to level the block and a pair of screw-tightened clamps engaging the ends 01" the block and a cam-tightened clamp engaging the middle and other side of the block from said screw-clamps.
