SAMUEL M. FRIEDE, OF ST. LOUIS, MISSOURI, ASSIGNOR OF ONE-THIRD TO JOHN W. DONNELL, OF SAME PLACE.

COMBINED MONKEY AND PIPE WRENCH.

SPECIFICATION forming part of Letters Patent No. 530,518, dated December 11, 1894.

Application filed January 29. 1894. SerielNo. 193,307- (No model.)

and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to a combined monkey and pipe wrench, in which a smooth faced outer grip jaw has a fast mount on one end of a bail shaped head frame, and a ratchet faced outer grip j aw also has a like fast mount on the reverse end of said head frame, both of said jaws having right angle grip holds. A flattened screw stem connects from said jaw to jaw, and seated and working thereon is an adjustable intermediate grip jaw, which has a smooth right angle face presenting toward the first named smooth faced jaw for effecting a monkey grip in connection therewith, and a smooth bevel face presentation toward the second named ratchet jaw for efiecting a pipe grip, with preferably a stiff operating handle integral with the jaw carrier head; and the invention consists in fea-- tures of novelty hereinafter fully described and pointed out in the claims.

Figure I is a side view of the preferred form of this wrench, and shows a still operating handle integral with the jaw carrier head. Fig. II is a detail edge view of the same.

Referring to the drawings:-1 represents the bail shaped grip-jaw carrier head-frame.

2 is the preferred form of handle which is integral with said head-frame.

11 represents the straight guide face of the bail shaped shoulder bar 12 of the grip jaw carrier head frame, and 13 are the angle ends of said shoulder bar,which respectively integrally unite with the smooth faced right angle grip jaw 14: at one end, constituting the fast moiety of the monkey grip jaw, and at the other end integrally unites with the ratchet faced right angle grip jaw 15.

16 represents a flat screw carrier bar, the jointed ends of which are seated in the mortises 17 in said respective fast mounted monkey and ratchet pipe grip jaws. 18 are the joint pins that are seated in the pin holes 19. in said jaws and bar, and secure the said bar in its seat, and 20 are the screw threads on the edges of said flat screw carrier bar 16. 21 represents the combination traveler jaw that is mounted by means of its holder slot 22 on said carrier bar, and 23 is a cross slot in which ishoused the operator wheel 24:, the central screw threaded slot 25 in which wheel runs on said flat screw stem 16; and thus as the thumb of the operator is worked on the milled periphery 26 of said operator wheel 24, the said combination traveler jaw 21 is made to respectively travel to bring its square straight face 27 to the grip distance required in conjunction with the square straight face 28 of the aforesaid stationary monkey wrench jaw 14, or in the reverse direction, to bring the bevel face 29 of said adjustable jaw to the grip distance required in conjunction with the square ratchet face 30 of the aforesaid pipe grip jaw 15. 31 represents the square faced extension heel of said combination monkey and pipe traveler grip jaw, the flat contact face of which heel as it travels to and fro along the guide face 11 of the shoulder bar 12, holds said traveler jaw square to its work.

A wrench with an integral handle is cited as my preferred form in this application. Elements of a transposable handle in a wrench entered into the combination shown and described in another of my pending applications on wrenches, filed January 3, 1894, Serial No. 495,326, in which said transposable handle aided the access to and working of the wrench in positions otherwise difiicult of access, and is of great advantage, but in cases Where the work is easy of access the integral stiff handle herein described is pref erable, as it is more simple to handle and its pipe grip is more durable.

The present invention, as disclosed in these drawings and specification, also better adapts my wrench for handling hard metal pipes, in that the bevel pipe grip face of the movable jaw is shown and described with a smooth grip surface, it having been found that the ratchet face of the movable jaw especially is more susceptible .to injury in course of adj ustment and gripping steel and other hard metal pipes, than is the smooth grip surface of the movable jaw. It is also found that the one ratched grip surface on the immovable jaw, besides being less susceptible to injury than on the adjustable jaw is also generally amply su'fficient with the aid of the smooth faced adjustable jaw to firmly hold its grip.

Another especial advantage and useful function of the bevel smooth face 20 of the combination traveler jaw 21, in conjunction with one of the respective ratchet holds of the pipe grip jaw 15, is for a special safety hold of fine finished sexangular, septagon, or octagon nuts, one angle face of which is seated against said bevel face 29 of said traveler jaw 21, and the union corner between two of the other sides of said nut is held in one of the recess beds between adjoining ratchet teeth of the jaw 15, where it is thus firmly held by said jaw in combination with the screw traveler jaw 21.

I claim as my invention 1. In a combined monkey and pipe wrench, the combination of the grip jaw carrier head frame 1, the stationary outer grip jaws integral with said frame, the operating handle 2, integral with said frame, the flat screw carrier bar 16, that connects said outer jaws, and the intermediate traveler grip jaw that is mounted on said carrier bar; substantially as shown and described.

. 2. In a combined monkey and pipe wrench,

the combination of the grip jaw carrier head frame, the stationary outer monkey grip jaw 14, the stationary outer pipe ratchet grip jaw 15, said jaws integral with said head frame, the operating handle 2 integral with said frame, the fiat screw carrier bar 16, the intermediate traveler combined monkey and pipe grip jaw, mounted .on said bar, the said jaw having the smooth square grip face 27, and the smooth bevel pipe grip face 29, and the screw threaded operating wheel 24; substan tially as described.

3. In a combined monkey and pipe wrench, the combination of the grip jaw carrier head frame, the outer square smooth face grip jaw 14, the outer ratchet square face grip jaw 15, the operating handle 2, integral with said head frame, the said head frame having the bail shaped shoulder bar 12 with angle ends 13, and the straight guide face 11, the fiat screw carrier bar 16, the intermediate traveler combined monkey and pipe grip jaw 21, mounted on said bar, said jaw having the smooth square monkey grip face 27, the smooth bevel pipe grip face 29, and the square faced extension heel 31, and the operating screw threaded wheel 24; substantially as shown and described.
