Serial No. 748,170.

To all whom it may concern Be it known that I, ALFRED HILL, a sub- Czar of Russia, residing at Cathl'amet, in the county of Wahkiakumand State of Washington, have invented a new and useful Combination Wrench and Pipe- Cutter, of which the following is a specifi'cation.

The present invention appertalns to a combination tool, and aims to prov de a tool or implement combining an ordinary wrench, a pipe wrench and apipe cutter.

The present invention also aims to pro vide a device of the character indicated which shall be comparatively simple, and 1nexpensive in construction, as Well as con- Venient and serviceable in its use, it also being the object of the invention to improve i ices of that character to which the present invention appertains.

With the foregoing and other ob ects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described andclaimed, it being understood that changes in the precise embodiment of invention can be made within the scope of what is claimed without departing from the spirit of the invention.

Lihe invention has been preferred embodiment in the accompanying drawing, wherein corresponding referencecharacters have been employed to denote corresponding parts, and wherein Figure 1 is a side elevation of the impl'ement as employed as a pipe wrench, parts being broken away. Fig. 2 is a sectional view taken on the line 2 2' of Fig. 1-, showing the device as employed for cutting pipes or other circular stock. Fig. 3' is a sectional View taken onthe line 3-3 of Fig. 1-, showing the movable jaw provided with a rotatory cutter, as in Fig. 2. Fig. 4 is a plan view of the key for swiveling the inner end of the actuating rod to the movable jaw. Fig. 5 is a side elevation, and Fig. 6- is a perspective'view of one of the supplemental or auxiliary jaws for gripping a pipe or other circular stock. Fig. 7 is a side elevation of a modified form of the invention, parts being broken away. Fig. 8 is a sectional detail through the movable aw of the form shown 'enerally and to increase the utility of de-= illustrated in its in Fig. 7. Fig. 9 is a fragmental perspective of another variation, and Fig. 10 IS a section detail of the variation illustrated in Fig. 9.

Referring specifically to the drawing, the numeral 7 designates the stock, handle or body of the implement which is preferabl fashioned from a fiat bar and has its neck portion 8 off-set, but lying in the same plane. The upper or inner end of the body is provided with a head or stationary jaw 9, w ich may be said to be in alinement with the lower or outer portion of the body. The stationary jaw 9, neck 8, and the body or handle 7 are preferably integral. The movable jaw has been designated generally by the numeral 10, the same comprising a block or jaw proper 11 having a check 12 bearing against or fitting one side of theneck 8, and a second or independent check 13 lying against or fitting the other side of the neck and abutting against the cheek 12 at the edges of the neck. The checks are secured together at the edges of the neck 8 by means of screws 14 passing through the end portions of the cheek 13 and screw threaded into the check 12, the check 18 abutting or fitting against the shoulder of the block 11 formed by the check 12, and the two cheeks preferably being provided with the inner ribs 15 engaging in the longitudinal channels 16 in the sides of the neck.

The complementary faces of the jaws are flat with the exception that the respective jaws 9 and 10'are provided with the recesses 17 and 17 in their faces. These recesses are comparatively narrow, concaved and deep, and are parallel with the sides of the jaws. Tapered pins 18 and 18 are also carried by the respective jaws 9 and 10 and pass through the recesses 17 and 17, the

pins beingreadily removable therefrom or insertible into the jaws.

Ordinarily, when the faces of the jaws are unobstructed, by the attachments hereinafter described the device may be employed in the usual capacity of a wrench for nuts and other objects, the recesses 17 and 17 being such as not to interfere with the utility of the device as a nut wrench or the like. In order that the device may be employed as a pipe cutter, the rotatory cutters or disks 19 and 19' are adapted to fit into the respective recesses 17 and 17 of the jaws, the pins 18 and .18, having been withdrawn and then having been again inserted to pass through the central apertures which are provided in the cutters. In this manner, the cutters are mounted for rotation Within the jaws, and project partially from the faces of the jaws in such a manner that when the jaws are brought together, the cutters are designed to properly engage the pipe or other stock for effecting the cutting'thereof, as will be understood. p p

In order that the device may be employed as a wrench for pi es or other circular stock, instead of employing the cutters, a pair of supplemental or auxiliary jaws are employed,-the-same being of a contour similar to the jaws 9 and 10 and having their faces properly toothed. The backs of the supplemental jaws 20 are provided with the ears 21 and are adapted to enter or fit within the respective recesses 17 and 17 of the jaws, so that the locking pins may be passed through apertures in the ears to retain the supplemental jaws in position.

The supplemental jaws are adapted to grip the pipe or other stock so that it may be properly rotated or held in a stationary position, whichever is desired. The supple I mental aws are designed to fit against the faces of the permanent or primary jaws so that the pins 18 and 18 are not subjected to undue strain.

The means for actuating the movable jaw consists in an actuating rod22 screw threaded through the lower or main portion of the stock or body 7, and provided at its outer end with suitable hand hold 23, the rod being provided at its inner end with an annular or'circumferential groove 24 providing a neck 25 and a head 26. The inner end of'the actuating rod 22 is adapted to fit within a pocket 27 in the bottom of the movable jaw 10, and the movable jaw is also provided with a dove-tailed channel 28 opening at one side and receiving a dove-tailed key 29 hav ing an open slot 30. The open slot 30 of the key is adapted to receive the neck 25 of the actuating rod, the key straddling said neck in order that the head 26 may set on the key for constraining the actuating rod and movable jaw' from separation but permitting a rotatory movement of the former. The actuating rod is thus swiveled efiectively to the movable jaw, and by rotatin the rod, it may be made to travel inwardly or outwardly, accordingly moving the movable jaw.

It will be evident from the foregoing, that the various parts are readily assembled and also readily capable of separation for the purpose of cleaning, repair or replacement.

As above indicated, the device may ordinarily be employed in the capacity of a nut wrench or the like, and either the cutters or the supplemental jaws may be applied to the jaws 9 and 10, so that the device may be employed in the capacity of a pipe cutter or a pipe wrench,

In'the form depicted in Fig. 7, the stock or handle 7 is provided with the ofl'set neck 8 having the stationary jaw 9, the movable jaw 11 slidably engaging the neck 8 as in the form above described. In this modified form the stationary jaw 9 is provided with a pair of recesses 17 a into which the rollers 19 are adapted to fit, tapered pins 18 being passed through the jaw 9 to journal the rollers 19 in the recesses 17. 19 are adapted to engage one side of the pipe or the stock to be out, while the cutter 19 carried by the movable jaw engages the other side. In this modified form, there is also disclosed a tapered pin or key 29 carried by the movable jaw and engaging through one side of the groove 24: of the actuating bar 22'.

In the variation illustrated in Figs. 9 and The rollers 10, the movable j aw-or block 11 is provided with a lower cut away portion or rabbet 31 extending away from the shoulder provided by the block and its cheek and the cheek 13 is provided with an extension 32 normally fitting in the cut away portion or rabbet 31, the extension 32 and the adjoining portion of the jaw 11" having complementary notches to embrace the inner end or head of the actuating rod so as to swivel the inner end of the actuating rod to the mov able jaw, and the inner end of the rod engaging snugly with the block, in order to jam directly against the solid block 11" when the rod is adjusted toward the stationary jaw.

What is claimed is 1. In a device'of the character described, a stock having a jaw at one end, a movable jaw embodying a solid block having a check fitting one side of the stock and forming a shoulder, a cheek fitting the other side of the stock and abutting against the said shoul der, the cheeks abutting at the edges of the stock, means for securin the cheeks together at the edges of the stoc and an actuating shoulder, a check fitting the other side of the stock and abutting against the said shoulder, the cheeks abutting at the edges of the stock, means for securing the cheeks together at the edges of the stock, an actuating rod in screw threaded engagement with the stock and having a circumferential groove at its inner end, the block having a In testimony that I claim the foregoing as lower rabbet extending away from the my own, I have hereto afiixed my signature 10 shoulder and the last mentioned cheek havin the presence of two Witnesses.
