Specification of Letters Patent.

Patented Ang. 5, 1919 Application filed October 22, 1918. Serial No. 259,272.

2'@ all 10km/1. 'it may concern:

. Be it known that l, EowAm) .l filmes. a citizen of the United States, and resident of iewton, in the count-y of Jasper and State of iowa, have invented a certain new and useful Viso, of which the following is a specification.

l It the object of my invention to provide a vise of very simple, and inexpensive construction.

More particularly it is my object to provide a vise of the type which can be used for holding a piston either in upright or inverted pos yion so t `iat in one of said positions the connecting rod may be extended downwardly from the vise with the piston extended upwardly from the vise so as to permit proper access to thepiston rings.

Still a further object is to provide such a device so constructed and arranged ast-o be readily adapted for use in firmly holding pistons of different maximum diameters.

ill/'ith these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed ont in my claims and illustrated in the accompanying drawings, in which:

Figure 1 shows a top or plan view of my improved vise.

Fig. 2 shows a side elevation of the same. Fig. 3 showsl a vertical, sectional view taken on the line 3--3 of Fig. 1; and

Fig. t shows a vertical, sectional view taken on the line 4-l of Fig. 1.

My in'iproved device comprises a base indicated in the accompanying drawings by the reference character 1() and having at its ends bolt holes 11 to receive bolts or the like for securing the base to a table or support. The base has on opposite sides 11p- Wardly extending curved ' ianges 12 and 13. At the lower partof each flange 13 is a portion of the base forming an inwardly extending shelf. The shelf at the lower part of the iiange 12 is numbered 1l and is lower than the Shelf 15 at the lower part of the flange 13.

Between the shelves 14 and 15 is acentral opening 16 to pern'iit the connecting rod on a piston to extend through the vise.

At the ends of the fianges 12 and 13 are lateral extensions 17.

Fixed in the extensions 17 are transverse rods 1S. Resting above the shelf 11 is a curved yoke 19 hayiug mounted on the 'rods lil, 1 and 4.

On each rod 18 between the yoke 19 and the extension 17 of the flange 18 is a coil spring 20.

Formed on the flange 12 is an internally screw-threaded bearing 21 into which is screwed a rod The inner end of the rod 22 is received in a recess 23 in the yoke 15), as illustrated in Figs. 1 and 2.

0n the upper end of the rod is a suit:- able handle it. will be seen that by manipulating the handle 2-l'the screw 22 may be operated for forcing the yoke 15) toward the flange 13 against the pressure of thevsprings 20.

At the lower edge of the yoke 19 is an inwardly entending shelf 25, the upper surface of' which islevel with the upper surface of the shelf 15.

In the actual use of my device I preferably place on the inner surfaces of the flange 13 and yoke 19 segments 2G of Babbitt metal which rest on the shelves 25 and 15.

For adapting my piston vise to be used with pistons of different external diameters, l provide broken rings 27 which fit inside the Babbitmetal segments, as illustrated in Fig. 1. As many of the rings 2T may be employed as desired to make the viste lit the piston.

lilith a vise of this kind the piston may be placed n the vise either end up for holding the piston in convenient position for all the work that. may have to be done on it,

rlhe ril'igs 27 should be somewhat resi-lient to permit their being sprung to some extent.

lt will be noted that one feature of applicants device is the arrangement of the shelf portions '14 'and 15. The upper surface of the shelf portion 15 is higher than the upper face or portion of the shelf portion 14.

This structure is necessary in order to furnish a suitable support for the slidably mounted gripping member 1S), and also in order to permit the shelf member 25 on the gripping member 1S) to have its' upper surface flush or level w'ith the upper surface of the shelf portion 15, so that the' shelf po. 'i5 and the shelf member 25 may pr. 4 f support the split ring 27.
