i T all whom it may concern:

Beit known thatI, JOHN A. ABoL'r, a citizen of the United States, residing at Eldon, in the county of Wapello and State of Iowa, have inof the invention, such as will enable others skilled in the art to which it appertains to rnake and use the same.

This invention relates to improvements in combination-tools.

The object of the invention is to provide a combination-tool yconsisting of a nut, a pipewrench, and a drill-chuck.

Another object is to provide a combinationtool of this character having a ratchet-handle for holding the same.

A further object is to provide a combination-'tool which will be simple, strong and durable in construction,adjustable,and readily transformed for use in its various capacities.

With theseand other Jobjects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of the tool, showing the same arranged for use as a nut and pipe wrench. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a transverse vertical sectional view throughv the handle, showing the ratchet connection of the same with the head of the wrench. Fig. 4 is a horizontal formed a longitudinally disposed circular openingl 3.

In the opening 3 is arranged the hollow circular shank or stem 4 of a head 5, said head being disposed adjacent to one side of the upper end of the handle, as shown. On the opposite end of the shank or stem 4is mounted a nut 6, having a milled flange 7. Said nut 6 is provided with a set-screw 8, whereby the same may be rigidly attached to the end of said stem 4. That portion of the vstem 4 which lies between the bifurcated upper end of the handle is squared, and on said 'squared portion is mounted a ratchet-disk 9.

The head 5 is formed with laterally-projecting anges 10, on the inner sides of which are formed transversely-disposed grooves or channels12. On the outer edges of said fianges 10, adjacent to one end of the same, is formed an outwardly-projecting block 18, in which is formed a V-shaped recess 14, whereby said block is adapted to formthe iiXed jaw of a nut-engaging wrench.

Slidably mounted. between flanges 10 is a block 15', having on its side edges iianges 16, which are adapted to engage the grooves or channels 12 in the iianges 10, whereby said block is adapted to have a sliding or adjustable connection with thehead of the wrench. On the outer face-of said block 15 is formed an outwardly-projecting block 17, in which is formed a V-shaped recess 18, said recess 18 being adapted to coact with the recess 14 of the stationary jaw-block 13, thereby forming an adjustable recess or socketto receive the nut or tap that it is desired to screw orA unscrew. In the block 15 is formed an elongated longitudinally-disposed passage 19, which is adapted to coincide at all times with the passage in the stem 4 and head 5 of the wrench.

In one of the ianges'l() in the head 5 is arranged a set-screw 20, which is adapted to be screwed into engagement with a recessed portion 21, formed in the adjacent iiange 16 tirely removed from engagement with the y head 5. In the flange 10 on the opposite side of the head 5 is arranged a set-screw 22,

which is adapted to be screwed into engagement with one of a series of depressions formed in the adjacent side of the block 15,

thereby holding the same in its adjusted positions.

IOO

In the bifurcated upper end of the handle is arranged a double pawl 23, which is pivotally mounted upon a pin or bolt 24, passed through said head. The upper ends of the pawl are adapted to be brought into engagement with the teeth on one or the other side of the ratchet-wheel or disk 9, so that when said handle is rocked in this direction said ratchetwheel and the head of the wrench 'will be turned thereby, a reverse movement of the wrenchhandle causing said pawl to play loosely over`the teeth of the ratchet-wheel, thereby preventing the retrograde movement of said wrench-head. When it is desired to turn the wrench-head in an opposite direction, the end of the pawl on the opposite side of the handle will be engaged with the teeth on the adjacent side of said ratchet-wheel, while the pawl on the first-mentioned side would be thrown out of engagement with said teeth. In order that the pawl 23 may be rocked to engage the ends of the same with the teeth on either side of the ratchet-wheel, a tripblock 25 is provided, said block having formed on one side an outwardly-projecting lug which is adapted to engage a recess 26, formed in the adjacent end of the pawl 23, whereby when said block is forced to one side or the other said pawl will be rocked upon its pivotpin 24, thereby causing one or the other of the ends of the same to engage the teeth of said ratchet-wheel. rIhe block 25 is adapted to be held into engagement with the adjacent end of the pawl by means of a coiled spring 27, which is seated in a 'recess formed in the handle 1, the opposite end of said spring engaging a pin or stud formed on the adjacent side of said trip-block. On the opposite end of the handle l is mounted a pipe-wrench 28, which consists of a head 29, in one side of which is formed a recess 30, the inner wall of which is beveled or inclined, as shown at 31. In said beveled wall of the recess 30 is formed a groove or channel 32, which connects with an aperture 33, formed in the opposite side of the head 29. On the inclined wall 31 is slidably mounted a plate 34, which forms the inner movable jaw of the pipe-wrench. On the lower side of said plate 34 is formed a fiange 35, which is continued beyond the inner end of said plate in the form of a pin or bolt 35', which is adapted to project through the aperture 83, the flange 35 being adapted to engage and slide in the channel 32, said iiange and bolt thereby forming guiding and retaining elements for said plate 34. A portion of the flange 35 beneath the plate 34 is cut away to form a recess 37, through which is adapted to project a pin 38, which is passed through the side of the wrench-head 29, said pin thereby limiting the outward movement of the plate 34, as will be understood. On the wall or face of the recess 30 opposite to the beveled Wall 31 is arranged a plate 3 9, which is adapted to form the outer jaw of the pipe-wrench, said plate being removably secured to the adjacent portion of the wrench-head by means of screws or rivets 40, whereby when the same becomes worn out it may be removed and replaced by anew plate. On the opposite faces of the plates 34 and 39 are formed oppositelyprojecting teeth 41, whereby the same are adapted to take a firm grip upon the pipe or rod to be turned.

The wrench-head 29 may be secured to the end of the handle 1 in any suitable manner, but is here shown as being provided with a threaded aperture 42, by means of which the wrench-head is adapted to be secured onto the reduced threaded end of the handle 1.

When applying the wrench to a nut, the set-screw 8 in the nut 6 is loosened, thereby permitting the end of the stem 4 to turn loosely therein. rIhe milled iange of the nut is now grasped in one hand, thus pivotally supporting this end of the stein, while the jaws of the head of the wrench at the opposite end of the stem are in engagement with the nut to be screwed on or ofi", the handle being grasped and operated by the other hand to turn the nut.

Referring to Figs. 5 and 6, in which the tool is arranged for use as a drill and in which the wrench stem and head 4 and 5 have been removed from the handle 1 and in place thereof has been inserted a shank or stem 44, having formed on one end thereof a drill-chuck 45, in which is formed a centrally-disposed socket for the reception of the end of a drillpoint 46, said drill-point being removably held in said chuck by means of a set-screw 47, as shown. The stem 44 is provided with a squared portion 48, which is adapted to receive the ratchet-wheel 9, and on the opposite end of the stem 44, adjacent to the outer side of the wrench -handle, is arranged the milled nut 6 in the same manner as in the connection with the nut-wrench stem shown in the first ligu re of the drawings. The stem 44 is provided throughout its length with screwthreads, and on the same is adapted to be screwed an interiorly-threaded feeding-sleeve 49, on the outer end of which is formed a reduced cylindrical lug 50, having a pointed or conical-shaped end 51, whereby the same may be engaged with a fixed jaw to enable the drill to be fed by the turning of the stem and drill-chuck, as will be understood. When desired, an apertured cross-bar 52 is arranged upon the lug 50, said bar being loosely held upon said lug by means of a set-screw 53, which is passed through one edge of the same and is adapted to engage an annular groove 54. On one end of the bar 52 is connected the end of a chain 55, which is adapted to be passed around the object to be drilled and to have its opposite end connected with the forked opposite end of the bar 52, thereby IOO IIO

holding the object being drilled in place and affording a bearing against which the drill may operate.

In Fig. 7 of the drawings is shown a connecting bar or stem 56, having squared ends whereby the same mayv vbe inserted in the squared outer end of the passage of the hollow stem 4. With the opposite end of the bar 56 may be engaged a brace by which the stem and wrench-head may be operated instead of by the handle 1. Y

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiringa more extended application.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

l. In a tool of the character described, the combination with an operating-handle having a bifurcated outer end, of a hollow tool carrying a stem loosely mounted in said end of the handle, aanged wrench-head arranged on the end of s aid stem, a fixed jaw formed on the outer edge of one end of the flange of said head, a block slidably mounted between the same, a jaw formed on said block to coact with said fixed jaw, a set-screw whereby the movement of said slidably-mounted jaw is limited, and means whereby the same is held in an adjusted position, and a double pawl and trip-block arranged on said stem and handle whereby the head is turned by said handle, substantially as described.

2. In a tool of the character described, the combination with an operating-handle having a bifurcated outer end of a hollow tool-carrying stem loosely mounted in said end of the handle, a flanged wrench-head arranged on the end of said stem, a fixed jaw formed on the outer edge of one end'oi:` the flanges of said head, a block slidably mounted between the same, a jaw formed on said block to coact with the said xed jaw, a set-screw whereby the movement of said slidably-mounted jaw is limited and means whereby it is heldin an adjusted position, a ratchet-wheel iXedly mounted on said stem in the bifurcated end of said handle, a double pawl mounted in the latter to engage one side or the other of said wheel, a spring-pressed tripping-block adapted to rock and automatically hold said pawl into engagement with one side or the other of said ratchetwheel, and a hand-nut loosely mounted on the free end of said stem whereby said wrenchhead is rotatably held in engagement with the nut to be turned, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
