COMBINATION-TOOL.

Specification of Letters Patent.

Patented May 14, 1912.

Application filed April 13, 1911. Serial No. 620,745.

To all whom it may cmwern Be it known that I, F RANK E. F0011, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Combination- Tools, of which the following is a specification.

This invention is for lifting heavy loads such as vehicles and machinery, for pulling posts, stumps, and the like, for holding the ends of severed wires and bringing them together for splicing, for stretching fence wires, and as a vise or clamp for the usual purposes of such appliances.

The object of the invention is to provide a strong, simple, and inexpensive tool for the above uses, which will be positive and sure in its adjustments, and which can be assembled and dismantled readily to permit the separate use of its parts.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a view in side elevation and partial section of my improved tool. Fig. 2 is a detail of same showing the parts in full which are shown in section in Fig. 1. Fig. 3 is a cross section on the line 33 of Fig. 2. Fig. 4 is a view in side elevation and Fig. 5 is a plan View of the spring bar for controlling the position of the pawl in the upper runner and Fig. 6 is a plan view of the base plate of the tool.

Like characters of reference indicate like parts throughout the several views of the drawings.

7 is the main or standard bar of my tool having ratchet teeth 6 along one edge and 8 a removable base-plate which is preferably of the shape of a shoe sole as shown in Fig. 6, to adapt that part of the tool for use as a last in repairing shoes. The soleplate has a lug with a socket therein to receive the end of the standard 7, the standard being removably secured in the socket by a cotter-pin 9 to permit it to be taken off when the tool is used as a wire stretcher. To the opposite end of the standard-bar 7 is a handle 10, having a socket to receive the upper end of the standard-bar. The latter is secured in the socket by a cotterpin 11.

12 is a movable hook-head, preferably of malleable iron, formed with two parallel side plates between which the standard-bar 7 is inserted as shown in the drawings.

13 is an operating-lever having a handle at its outer end and having its other end turned approximately at right angles and provided with an integral journal-pin 14. The pin is inserted through suitable openings in the two plates of the head 12. It has two opposite lugs 15 which pass through suitable enlargements of the pin-opening in the plate next the lever when the lever is suitably elevated and lock the pin against removal when the lever is lowered after such insertion. The lever 13 has a second pin 17 on the same side as and parallel with the pin 14. The plates of the head 12 have arcuate slots 18 concentric with openings for pin 14 through which pin 17 passes, and on the outer pin 17 one end of a pitman 19 is mounted. The pitman 18 has an eye at its lower end and a laterally projecting arm 20 with a lug or pin 21 on its upper face.

A lower runner 22 is recessed to receive the lower end of the pitman l9 and arm 20, a suitable socket being formed to receive the rounded end of the pitman. A spring 23, retained in position by pin 21, presses down against the arm 20 with a resulting tendency of moving or swinging the body of runner 22 upwardly around the lower end of the pitman as a pivot. A bite-member 24 of hardened steel, is inserted in the runner to contact with the standard 7 and the action of the spring 23 keeps the bite member in contact with the bar 7.

25 is a second or upper runner of the same general construction as the lower runner 22, but in reversed position. It has a pitman 26 similar to pitman 19, with an arm 20 and spring 23 for the same purpose. The upper end of pitman 26 has its bearing in .a socket in an extension 27 of the hook-head 12. The essential difference in construction between the upper and lower runners is that instead of a bite-member 24, a pawl 28 is mounted in a suitable cavity in the runner, on a pivotbolt 29, and the free pointed end of the pawl is adapted to engage with the ratchet teeth of the standard-bar 7. This change is to insure stronger and more positive engagement or hold between the bar 7 and runner 25 than is possible with a bite-member 24 as in the lower runner 22.

To hold the pawl 28 in such yielding engagement with the bar 7 as will permit it Then the handle 32 is in notch 34 the pawl 28 will be held out of engagement with the notches of bar 7, which is the position when the runner 2-5 is to be lowered; but when the handle 32 is in notch 35 the pawl is held vyieldingly in contact with ratchet teeth 6 of bar 7.

The handle 10 at the upper end of standard-bar 7 is provided with a vise or aw extension tocooperate with the corresponding jaw formed by the extension 27 of head 12. As the handle 10 and head 12 are preferably made out of malleable iron which is too soft for good vise jaws, I provide dove tailed channels in the two jaws and drive correspondingly shaped bearing blocks 42 of hardened steel therein, to take the wear. This is an important feature in a practicable tool.

Extending longitudinally of the bar 7 across the handle-piece is a toothed bar 44: having an overhanging flange, and pivotally secured to the handle-piece is a serrated cam-segment lever 45, to make clamping engagement with a wire placed bet-ween the bar 4st and cam-lever 45.

The head 12 has the toothed extension 47 cooperating with a serrated cam-lever 4L8 pivoted adjacent to the extension L7. These Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, 7

gage the teeth of the standard-bar, a spring-- bar attached at one end to the pawl and having its other end bent and extending through said slot in the plate of the runner, and said slot having notches to hold given adjustments of the bar.

2. A toothed standard-bar, a hollow run- I ner slidingly mounted on the bar'having a slotted plate with end notches, a pawl' mounted in the runner and adapted to engage the teeth of the bar, and a spring-bar having one end bent and attached to the pawl and the other end bent and passed out of the runner-plate through its slot and adapted to engage the notches in the slot, said spring-bar having a coil between 1ts ends to give it resillency.

In witness whereof, I, have hereunto set 7 my hand and seal at Indianapolis, Indiana,

this, 20th day of ()ctober, A. D. one thousand nine hundred and ten.
