Specification of Letters Patent.

Application filed August 5, 1919. Serial No. 315,506.

To all whom it may concern:

Be it known that I, HERMAN D. Snrrz- MAN, a citizen of the United States, and a which may be used in connection with any.

form or shape of nut, bolt head, orpipe,

- and which will eificiently perform its functions in all uses.

A further object is to provide a wrench which will be extremely simple in construction, which can be manufactured at a reasonably low price, which is not liable to get out of order, and which will be extremely strong and durable in use.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangement of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in side elevation partly in section illustrating one form of my invention.

Fig. 2 is an edge view at right angles to Fig. 1.

Fig. 3 is a fragmentary view of the opposite edge of the wrench shown in Fig. 1.

Fig. 4 is a fra mentary view showing the opposite side of the jaws shown in Fig. 1.

Fig. 5 is a view in transverse section on the line 55 of Fig; 1.

Fig. 6 is a perspective view of the split collar 12.

Fig. 7 is a fragmentary view in side elevation illustrating a modification of my inven tion in which the jaws are to be used for en-- gaging apipe.

Fig. 8 1s a fragmentary view in section on the line 8-8 of Fig. 7

1 represents a handle rod having a fixed jaw 2 at one end and milled hand hold 3 at its other end. The hand hold end 3 is provided with a socket 4 adapted to receive the shank 5 of any approved tool, and may be utilized with various tools as will be readily understood. The rod 1 has flat sides '6 and is screw threaded throughout a portion of its length as shown at 7 8 represents a movable jaw which is 'made with an integral boss 9 movable on therod 1 and having flat faces 10 located against the flat sides 6 of the rod, so that while the jaw is free to move longitudinally of the rod, it is held against the possibility of turning movement thereon. v

An adjusting sleeve 11 is positioned on the rod 1 and has internal screw threads 11 engaging the screw threads 7 so that the turning movement of the sleeve causes the same to move longitudinal of the rod.

A split collar 12 is secured tothe sleeve 11 by means of screws 13, and has an inwardly projecting annular flange 15 which engages an annular flange 16 on the-boss 9, the flange 15 cooperating with the end of sleeve 11 to compel the jaw 8 to move longitudinally when the sleeve 11 is turned.

Th'e'jaws 2 and 8 are located at right angles to the rod 1 and project beyondboth sides thereof. These jaws are provided" with a plurality of pairs of opposed angular recesses 16,17, 18, and 19 in the'sides and ends of the jaws 2 and 8 and these pairs of recesses are of different angular formations to accommodate any ordinary angular nut or bolt head in common'use. I

In the modification illustrated in Figs. 7 and 8, the fixed jaw 20 and movable jaw 21 are made with toothed recesses 22 and 23 respectively to engage a pipe. Thus this form of my invention constitutes a pipe wrench. The toothed recess 23 of the mov-.

able jaw 21 is provided in a movable portion 21 of the jaw, this movable portion 21 having a perforated car 2 1 located between a pair of perforated ears 25 on the boss 30 and pivotally connected by means of a pin 26. The car 24 has a beveled shoulder 27 which limits its pivotal movement and a spring 281s secured by a screw 29 to the boss 30, and holds the movable jaw 21 in normal position.

This pivotal movement of the portion 21 Patented Dec. 16, 1919.

of jaw 21 permits the wrench to be released from the pipe in its movement in one direction as is necessary with devices of this character.

The split collar 12 above referred to is preferably split at an angle as shown clearly in Fig. 6, which gives to the device an added strength over an ordinary straight split collar to sustain the strains and stresses of the movable jaw.

The two halves of the split collar can, of course, be inserted from opposite sides to permit a quick connection of the sleeve with the jaw, and the angularly disposed contacting surfaces sustain longitudinal strains when the sleeve is forced in one direction to press the jaws into operative position. They also sustain the strain in the opposite direction during the manipulation of the jaws.

While I have illustrated what I believe to be preferred embodiments of my invention, I would have it understood that I do not limit myself to the precise detail set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

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

1. A wrench, comprising a handle rod having a fixed jaw. at one end, said rod having a screw threaded portion, a movable jaw mounted to move on the rod and held against rotary movement thereon, a boss on the movable jaw, an annular flange on the boss, a screw threaded sleeve engaging the rod, a split collar having its members socured to the sleeve, and an internal annuiar flange on the split collar engaging over the flange of the movable jaw.

2. A wrench of the character described, comprising a handle rod, a fixed aw on one end of the rod, said rod having a screw threaded portion and having fiat sides, a movable jaw having a boss thereon, said boss receiving the rod and having fiat faces engaging the fiat sides of the rod, an adjusting sleeve having internal screw threads engaging the threads of the rod, a split collar secured to the sleeve and engaging the boss whereby the movable jaw is compelled to move on the rod when the sleeve is turned.

3. A wrench, comprising a handle rod having fiat sides, a fixed jaw on one end of the rod,-a movable jaw, a boss on the movable jaw receiving the rod, said boss and rod having flat faces whereby the jaw is held against rotary movement on the rod, an annular flange on the boss, a sleeve, said sleeve and rod having a screw threaded engagement, a split collar secured to the sleeve, and an internal annular flange on the collar engaging over the flange of the jaw whereby the movable jaw is compelled to move longitudinally of the rod when the sleeve is turned.

4:. A wrench, comprising a handle red, a fixed jaw on one end of the rod, a movable jaw on the rod, means for preventing rotary movement of the movable jaw on the rod, an adjusting sleeve on the rod, said sleeve and rod having a screw threaded engagement, at diagonally split collar connecting the sleeve and movable jaw, said jaws projecting on both sides of the rod and having in their ends and sides pairs of opposed angular recesses.

5. A wrench, comprising a handle rod, fixed jaw on the rod, a movable jaw on the rod, an adjusting sleeve having screw threaded connection with the rod, a diagonally split collar connecting the sleeve and the movable jaw, a pivotally supported section on the movable jaw having a limited movement relative to the jaw, a spring holding said movable section in one position, and said movable section and fixed jaw having opposed toothed pipe receiving recesses.
