, Specification of Letters Patent. Application fil d November 21,1905. Serial 110.288,.360.

Patented. March 20, 1906.

To all whom it may concern: Be it known that I, FRANK E. FooR, 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 relates to improvements in a tool which is particularly desirable on a farm for pulling posts, stretching fencewires, raising light buildings, leveling threshing-machines and portable engines, lifting heavy machinerysuch as hay-balers, mowers, and binders-and for elevating the axles of wagons and other vehicles for the removal of awheel.

The object of the invention is to provide, a strong, simple, and inexpensive tool which is adapted for the above usesand also to pro- .vlde a tool which can beused as a clamp and vise and as a means for holding the ends of bringing them together splicing.

severed Wires and for can be assembled and dismantled readily, so some of its parts can'be used separately from The ob'ect also is to provide meansfor unlocking the runners or clamps. without danger of injury to the fingers or hand of the opbyv the mechanism illustrated in the accompanying drawings, in which Figure 1 is a pers ective view of a tool embodying the specia i-features of my inven- Fig. 2 is a detail in edge view of the Fig. 3 is a section on the line 3 3 of Fig. 2 looking in the direction ofthe arrow. Fig. 4 is a view in side elevation-and partial section ofthe tool looking at the opposite sidefrom that shown in Fig. showing the in section in Fig. 4. Fig. 6 is a detail in perspective view- Fig. 7 is a i perspective view of the operating-lever, showi ing moreclearly the construction of the innor end and face of the-lever. Fig. 8'isa side view showing theadaptation of the tool for splicing wires, and Fig. 9 is a top view of the base or foot piece removed.

Like characters of reference indicate like parts throughout the several views of the drawings. r 1

is the base, which supports the bar 1 when the invention is used as a jack. This base is removably secured to the bar and is taken off to lighten the tool and render it more convenient when used as a wire-stretcher, as shown in Fig. 8.' The end of thebar 1 is provided with the perforation 3, (see Fig. 8,) and this perforated end is inserted in the socket 4. (See Fig. 9.) The-pivoted lever 5 has a hooked end which passes through the wall surrounding the socket and entering the perforation 3 fastens the base to the bar. The lever 5. is pressed by the spring 6 in a direction toforce the hook into the socket. The base-plate 2 has the claw end 7 for pulling staples and nails, and at its 0 posite end it has "the notches 8 to receive. olt-nuts,- thereby adapting the base when removed to be used as a Wrench, and the notches will be particularly adapted as, to size to fit the nuts of the tool itself, thereby providing a nut-wrench for the tool which is always at hand for convenient use.

9 is the movable hook-head of my device, preferably, made out of iron or cast-steel, formed which the bar 1 is inserted in the manneras clearly shown in Fig. 4. v I v '10 is an operating-lever having a handle at one end andits opposite end bent approximately at right angles and provided with a journal member or pin 11. The body of this pin is cylindrical; but midway of its length it as the two diametrically opposite' lugs 12.

This pin is inserted through suitable openings in the two plates of the through the plate next to the leverbeing shaped to allow the lugs l2to pass through when the lever is in the'p'osition shown'by the dotted lines, Fig. 4, and when the lever is lowered into working positions these lugs form alock to prevent the longitudinal displacement" of the pin 11. Thisconstruction is desirable,'for the reason that it provides an easy means for disengaging the lever 10 from the remainder of the tool when it is desired to use the lever 10 asa hammer, for which it isadapted by the addition ofthe drivinghead 13. The lever lOhas a secondpin 14 on the same side of the lever and parallel The plates of the head 9'are provided, with corresponding arcuate slots head 9, the opening 15, concentric with the openings for the pin 11, and through these slots the pin 14 on the lever 10-is passed in the manner as shown in the drawings. Mounted on the pin 14 is'the pitman 16. The pitman 16 has an eye at its its arm 17.

in the runner by means of the bolt 21 but because of the close fit ofthe pitman in the socket of the runner the lifting strain is taken off of the bolt, which is an important element of strength and durability in the construction of my tool. V

22 is a 'bite member of hardened steel,

i which is inserted in a suitably-formed pocket ner to which the pitman is attached, therebyin the runner on the opposite side of the bar 1 from the pitman 16. This bite member has downwardly sloping teeth contacting with the bar 1, and the weight, which is being elevated by the head 9, causes the member 22 to firmly engage the bar 1, except when it is released by an upward pull of the pitman 16, which raises that end of the runthrowing the opposite end of the runner carrying the member 22 away from and out of engagement with the bar 1. A spring 23, seated on the pin 18 of the arm 17, presses up against the top of the runner, so as to constantly elevate the end of the runner which carries the bite member 22, thereby keeping the latter in constant close contact with the bar 1. The spring will be held in place by a pin- 24 entering its coils from the top of the runner 25 is a second runner of the same construction as the runner 19, mounted on the bar 1 between the head 9 and the runner 19; but it is reversed in position, so as to bring its bite member 22 into contact with the opposite edge of the bar 1, and the opposite end of the runner 25 from that in which the bite member is located is connected by means of the pitman 26 with an extension of the head 9 on that side of the bar 1. The rounded ends of the pitman 26 bear in suitable sockets in both head 9 and runner 25, so as to relieve the bolts which secure them of strain. The pitman 26 has the same kind of an arm 17, with a pin 18 to engage a spring 23, which spring is held by a pin at the top of the runner and presses against the top of the runner in the same manner and for the same purposes as described for the runner 19.

The operation of my device as thus far described is as follows: When the operating-lever 10 (see Fig. 4) is raised to the position shown in dotted lines at the right of bar 1, the lower runner is raised to the position shown in dotted lines, and the weight of this runner and the weight of the head 9 and whatever weight may be resting on the head will be sustained by the middle runner 25. Thenwhen the lever 10 is lowered, say, to the position shown in full lines the weight is immediately transferred to the lower runner 19, causing the latter to grip the bar 1, and the downward movement of the operatinglever 10 causes the head 9 to move u on the bar 1. This upward movement of t 1e head loosens and releases the grip of the runner 25 and draws it up with the head 9. A second raising of the lever 10 throws the weight again on the runner 25 at its higher position, and then the runner 19 is brought up to a higher position on the bar 1, and the step-bystep movement progresses in this manner. It will thus be seen that the bar 1 is gripped upon alternate opposite sides, thereby making the strain more uniform and insuring greater durability and strength to the tool. By pressing down on the end of the runner in which the bite member 22 is located the runner swinging on its pivotal connection with the pitman at its opposite end will swing into a position that will release the bite member from contact with the bar 1.

The runner 25 is released, as above described, by means of a sliding wedge 28, which works between the top of the runner 25 and a lug 29, integral with the side of the head 9. Lateral displacement of the wedge is prevented by the flange 30 from lug 29. The edge of the runner 25 which contacts with the wedge has the projection 31 over the end of the runner to be depressed, so as to deliver the pressure from the wedge particularly at that part of the runner. The wide end of the wedge has a perforation, as shown, for easier grasping in making adjustments.

By the depression of the end of the runner holding the bite member the runner is disengaged from the bar 1 and the weight of the head and load on the head is transferred to the runner 19.

When the wedge 28 is brought into contact with the runner 25, the operating-lever 10 must be held by the operator. With the lever 10 in the position shown in full lines in Fig. 4 the lever may be gradually raised to the position shown in dotted lines in said figure, which causes the head 9 to be lowered. The wedge 28 is next moved to release the runner 25, and then by ressing down on that end of the runner 19 w iich is above the bite member 22 the runner 19 is thrown out of engagement with the bar 1, and the weight of the head 9 and its load is transferred to the runner 25 and is supported by said runner. The lever 10, being 1n the position shown in dotted lines to the right of bar 1 in Fig. 4, is next lowered, and the runner 19 is moved down on the bar 1 by the lowering of said lever 10. This forms a step-by-step movement, by means of which the load on the jack is lowered. The downward pressure on the end of runner 19 required to release it from part of the jack entirely from the handle,

thereby making it more convenient than if pressed down with the fingers, I provide the device which is best shown in Figs.1,12, and 3, in which 33 is an inte ral extension from the runner 19 and 34 a ink-bar connecting the end of the extension 33 with the lever 10.

The upper end of the bar. 34 terminates in the circular head 35, which is introduced between the head 9 and the lever 10 is made of spring metal which is curved inwardly at the middle, as best shown in Fig. 2,

36, the concave lower side of which forms a seat in which the circular upper end of thebar 34 has its bearing during the times when 1 and bears against the runner 25, so as to cause its upper end to press outfirmly against the lever 10. The lever 10 has the curved flange it is desired to press down on the end of the lower runner 19. When it is not desired that the bar be in engagement with the leverflange 36, the upper end of the barwill be pressed back by lowering the handle 10 until a wedge extension 37 from the hammer-head 13 has forced the bar away from the lever. After the lever 10 has thus been moved so the hammer-head 13 is below the bar 34 the lever can be operated to'work the jack without reengagement of the bar with the curved flange exce t by raising the lever abnormally high. In tl ie last position the end-of the bar will again enter the concave bend of the flange and will be capable of depressing the runner by the lowering of the lever. The lateral movement of the bar 34 is limited by the lugs 40 and 40 from the side of the head 9.

A plate 43 is secured to the u per end of the bar 1, and projecting lateral y from the plate is a handle 44. The-lower portion of this plate 43 is provided with a rigid vise or jaw 45 to cooperate with a corresponding jaw 46 on the rear. art of the head 9. Extending longitudina 1y of the bar 1 across the plate 43 is a toothed bar 47, which is overlapped by the plate 48, and pivotally secured to the plate 43 is a cam-segment lever 49, toothed upon its segmental portion to admit of firm clam ing and engagement with a wire introduced liietween the toothed bar, 47 and said cam-segment lever under the flange 48.

The head 9 has the toothed extension 50,

which cooperates with a cam-segment lever 51, ivoted to the head,9 adjacent to the tootlied extension 50. These parts provide means for clamping a wire to the head 9 in the manner as shown in Fig. 8, in which the wire is shown at 52.

Fig.7 8 represents my device as used for a wire-stretcher and shows one end of a wire held by the clamp on plate This bar.

43 and the end of the second wire held by the clamp on the head 9. With my device the ends of the wires may be drawn together and united by twisting while being held by my machine.
