WILLIAM F. IBONNARD AND SAMUEL E. KLEIN'KAUF, 013' LOS ANGELES, CALIFORNm LIF'IIN'G-TONGS FOR MOTORS, 8w.

Specification of Letters Patent.

Patented Sept. 23, 1919.

To all whom it may concern:

Be it known that we, WILLIAM F. BON- NARD and SAMUEL E. KLEINKAU'F, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Lifting-Tongs for Motors, 620., of which the following is a specification.

Our object is to make tongs for lifting motors and the like, and our invention con.- sists of the novel features herein shown, described and claimed.

Figure 1 is a side elevation of a lifting tongs, as indicated by the arrow 1 in Fig. 3, and embodying the principles of our invention, in use for lifting an engine, parts of the engine being broken away and shown in section.

Fig. 2 is a view in elevation at right angles to Fig. 1 as indicated by the arrow 2.

Fig. 3 is a view in elevation looking in the direction indicated by the arrow 3 in Fig. 1.

Fig. 1 shows a front view of the engine, Fig. 2 the right side, and Fig. 3 the left side.

Fig. 4 is an enlarged perspective of the tongs.

Referring to Fig. 4, the lifting tongs comprise bars 1 and 2 crossed and pivoted together like a pair of shears. The bar 1 comprises a ring 3, an arm 4 extending downwardly from the ring, a bearing 5 at the lower end of the arm 4, a second arm 6 extending downwardly from the bearing 5, and a crossbar 7 rigid with the lower end of the arm 6. The arm 6 is considerably longer than the arm 4, and the lower end of the arm 6- is curved downwardly and inwardly toward the lower end of the bar 2. The crossbar 7 is substantially parallel with the axis of the bearing 5 and is rigid with the lower'end of the arm 6. The bar 2 comprises a ring 8, an arm 9 extending downwardly from the ring 8, a bearing 10 at the lower end of the arm 9, and an arm 11 extending downwardly from the bearing 10 and having a hook 12 upon its lower end. The rings3 and 8 are substantially alike, the arms 4 and 9 are substantially alike, the bearings 5 and 10 are substantially alike, and the bearings are connected by a pivot pin 13. The lower end of the arm 11 is bent downwardly and inwardly toward the crossbar 7 to form the hook 12. Chain links 14 and 15' pass through the rings 3 and 8, and a large chain link 1f) connects the links 14 and 15. The links 14, 15 and 16 form a flexible connection between the rings 3 and 8 so as to allow therings 3 and 8 to s read apart thereby spreading the crossbar and the hook 12 apart, and so that when a rope, cable, or the like is connected to the ring 16 and pulled upwardly the crossbar 7 and hook 12 will be swung toward each other.

Referring to Figs. 1 and 3, the hook 12 is adapted to engage under the end of the head 17 between the cylinder pistons 18 and 19, and the crossbar 7 is adapted to engage under the manifold and valve extension 20 after the manifolds have been removed. The lower face of the extension 20 is substantially straight and the crossbar 7 fits against this straight face and serves to assist in balancing the engine when the engine is lifted bodily from its support.

If the engine were swung between two hooks 12 and lifted it would be practically impossible to balance the engine, one end of the engine would go up and the other would go down.

Various changes may be made without departing from the spirit of our invention as claimed.

We claim:

A lifting tongs for internal combustion motors comprising two bars crossed and pivoted together, a hook upon the lower end of one bar and adapted to engage under the head of the motor between the piston cylinders, a straight crossbar upon the lower end of the other bar and adapted to fit under the valve extension of the head ofthe motor so that the hook and crossbar will swing-to and from each other with the crossbar crosswise of the line of swing, said cross bar being of a length sufficient so that when applied to the head of the motor the hook and the ends of the cross bar will form a triangular base holding the head of the motor from tipping laterally, and a flexible connection between the upper ends of the bars so that when power is applied to lift the tongs the internal combustion motor will be lifted and balanced.

In testimony whereof we have signed our names to this specification.

W. F. BONNARD. S. E. KLEINKAUF.
