JAMES J. NOON, OF TORONTO, ONTARIO, CANADA.
WRENCH.
Specification of Letters Patent.
Application filed April 19, 1910.
ltatented Aug. .22, Serial No. 556,321.
To all whom it may concern:
Be it known that I, James J. NOON, a citizen of the United States, residing at the city of ioronto, in the county of York, Provincc of Ontario, Canada, have invented certain new and useful Improvements in renches, of which the following is a specification.
My invention relates to improvemeiits in wrenches, and the principal object of my invention is to provide a wrench which depends for its continuous grip on the work upon the indraw of the eccentrically-pivoted-movable jaw, that is, the movemei'it of the movable jaw toward the work, and the particular configuration of the grip )ingsurfaces, of said movable-jaw, and thetixed jaw-member, so as to always maintain the relative positions of those portions of the said gripping-surfaces between which the work is actually held, so that while the work is firmly gripped (in this case a pipe) there will be no danger of crushing the same, the position of these portions of the gripping surfaces in contact with the work always being such that a line drawn through the same will not pass through the center of the work, but will pass through the work in a position between the center thereof and the stem of the tool.
A still further object of my invention is to provide a wrench constructed of a small number of parts.
The construction of my preferred form of invention, and an alternative form thereof, will be hereinafter particularly described, and the parts I claim as new will he pointed out in the claims forming part of this specification.
Figure 1 is a perspective view of my preferred form of wrench showing it construct ed to be particularly used for tightening and loosening pipes. Fig. 9. is a longitudinal central section through the jaw and a portion of the stem or handle shown in Fig. 1. Fig. 3 is a side elevation of my preferred form of wrench, showing the action of the movable aw thereof when being used. Fig. 4 is a side elevation of my preferred form of wrench showing the same provided with cutting disks, and attachments in which the same are mounted. Fig. 5 is a vertical central section through the shoe in which the upper pair of cutting disks are mounted, hereinafter particularly explained.
llig. 6 is a perspective view of an alternative form of my wrench showing the same constructed for use in removing and tightening flanges and nuts, and Fig. T is a longitudinal central section through the jaw. and a portion of the stem or handle, shown in Fig. (3.
1n the drawings, like characters of reference indicate corresponding parts in each figure.
A is any suitable stem or handle, which carries the head 13. This head it mav be secured to, or integrally formed a part of the said stem or handle.
C is a sleeve which is mounted on the said stem or handle and has movement longitudinally thereof. The said sleeve is chambered as shown at I) so as to provide side walls I in which is held the retaining pin F. The said sleeve is 'n-ovided with a wall G having an outwardl vcurved foot ll which is concentric to the retaining pin 1*. The movable jaw-member l: has niovtnnent between the walls l and it is retained in place between the said walls by means of the retaining pin ll which passes through its bearing-web J. As shown in F 2, the bear ing-web J is concentric to the retaining-pin l 'lherefore it follows that the said hearing-web is always bearing upon the foot ll. The wall G- is really the back of the chan1- her I). The said sleeve is provided with a lower chamber 9, thus forming side-walls 3. Into this lower chamber extends the shoulder 4t of the pawl 5, and through this shoulder passes the retaining pin (3 which is held in the said walls 23. As will be understood, the lower end 7 of the pawl 5 engages with the teeth 8 of the ratchet which is formed in one edge of the stem or handle A- The said sleeve C is provided with a hole 9 through which extends the coiled spring '10. The lower end of the spring it) rests in the bed-way ll formed in the pawl 5, and the upper end of the spring rests in the bed way 12 formed in the jinv-mcmber l. By means of the said spring, it will be understood that the pawl is held in engagement: with the teeth 8 so as to lock the sleeve C in the desired position. lly means of the said s 'n'ing 10 the jaw-member l is spring held in position. The said sleeve (1 is chambered as shown at .3 so as to allow movement of the head 1 1: of the pawl 5 when it is desired to disengage the said pawl from the teeth 8. It will be noticed upon referring to Fit 2 that the walls of the sleeve C surrounding the stem or handle A are very stout. The inner front wall 15 of the said sleeve is preferably constructed so that its lower portion 16 will have a clearance with the teeth 8.
17 is any suitable pin or stop which limits the downward movement of the sleeve C.
The inner surface of the head B (this head is really the fixed member of the jaw) is concaved and is provided with the teeth 18.
Upon referring to Fig. 3 it wlll be seen that a pipe 20 is shown gripped between the head B and the movable jaw-member I. The said head and the movable jaw-member I are represented as exerting strains so as to twist the pipe 20 in the direction 1nd1- cated by arrow. When the wrench is to be used, the sleeve C is moved up so as to carry the movable jaw-member I agalnst the pipe and tilt it into the position shown in Fig. 3. 'When force is applied to the wrench, the strain exerted on the pipe 20 through the movable-jaw-member I causes said awmember to turn inward toward the stem or handle A until the pipe is gripped firmly between the head B and the said movable j aw-member. When the wrench is properly positioned the movement of the aw-member 1 before it takes grip, is inconsiderable. Should the movable jaw-member I slip, it
will move of course on its bearing web J (which always bears against the foot H) in the direction toward the stem or handle A, thus enabling the eccentric movement to throw the tooth immediately to the right of the one that slipped, into contact with the pipe. As the strain is continued, the eccentric inthrow of the movable jaw-member T tightens the grip on the pipe 20, thus positively preventing the wrench from slipping. The upper surface of the movable jawmember I is convexed, as illustrated. This construction of the same, together with the described construction of the inner surface of the head B, enables me to provide a tool of the class described, whereby while the work will be firmly gripped between those portions of the said gripping-surfaces actually in contact therewith, still there will be no danger of a crushing strain being brought into play. It is an important object of my invention to exert a twisting force on the work. The movement of the jaw-member T toward the stem A, moves the convexed surface thereof so as to compensate for the concaved shape of the gripping-surface of the head B, and so thus always maintain the relative position of those portions of the grippingsurfaces actually in contact with the work and between which the same is gripped. Should the grippingsurface of the head B slip on the work and thus move the stem A nearer the work, the indraw or inward movement of the jawmember T will cause the same to rock on its retaining pin F, thus relatively positioning the portion of the gripping-surface of this jaw-member T in contact with the work, in respect of the portion of the gripping-surface of the head B in contact therewith. The mounting of the movable jaw-member l eccentrically in the sleeve C permits the indraw of the said jaw-member, that is, its movement toward the work. As shown in Fig. 2, the back of the bearing-web J seats against-the wall Gr, thus limiting the in throw of the aw-member I.
In Figs. 6 and 7 T show a form of my wrench adapted to be used for removing and tightening flanges and nuts. Thehead B projects beyond both sides of the stem or handle A as shown and is provided with the usual teeth. In this form of my invention, the teeth 8 are formed in the side of the stem or handle A and the construction of the sleeve C is changed as shown so that the jaw-member T will co-act with either of the projecting sides of the head B 5 is the pawl which is suitably mounted in the sleeve C 5 is a coiled spring held in a pocket 0 formed in the sleeve C The said spring keeps the said pawl in engagement with the teeth 8 9 is a coiled spring held in a pocket (not shown) formed in the sleeve 0 The upper end of the said spring is held in a pocket (not shown) formed in the jaw-member T The stem or handle A is without a stop or pin in the path of movement of the sleeve C and therefore the said sleeve and the parts carried thereby can be slid off the handle and slid back thereon, so that the jaw-member I may be positioned to coact with the desired overhanging flange of the head B In Fig. 4 I show my pipe-wrench adapted for cutting pipe. To adapt my wrench for this purpose I remove the jaw-member I from the sleeve G, and mount in the said sleeve, after the manner described, a jawmember I in which. is mounted the cutting disk 21. 22 is the pin by means of which the cutting disk 21 is mounted in the jawmember 1 As shown by dotted lines in Fig. 4-, the aw-member T is provided with a slot 23 so as to accommodate the cutting disk 21. 9.4 and 25 are cutting disks mounted in the lower portion 26 of the shoe 2'? by means of the pins 28 and 29 respectively. 30 is the bridge connecting the two standards 31 and 32 of the said shoe togethcr. The under side of the said bridge is chambered so as to allow for the movement of the cutting disks 24: and 2:5. The upper side of the bridge 30 is provided with teeth 33 which coact with the teeth 18 of the head B so that the said shoe may be snugly held in place. 34 is an eccentric function of a jaw member; of a sleeve mounted to have longitudinal movement on said handle, and provided with upper and lower chambers, and further provided with a hole near its front portion; a movable jaw member co-acting with said head and eccentrically mounted in the upper chamber of said sleeve and having bearing against the same; a pawl mounted in the lower chamber in said sleeve and having an extension formed to engage with the teeth of said rack; a spring held in the hole formed in said sleeve and engaging said movable jaw member and said pawl, and a head integrally formed with said pawl whereby the same is readily manipulated.
i. In a wrench, the combination with a handle provided with a toothed-rack and a head for said handle provided with a concaved gripping surface and performing the function of a jaw member, of a sleeve mounted to have longitudinal movement on said handle and provided with upper and lower chambers and further provided with a hole near its front portion; a movable jaw member oo-acting with said head, and provided with a convex gripping surface and eccentrically mounted in the upper chamber of said sleeve and having bearing against the same; a pawl mounted in the lower chamber in said sleeve and having an extension formed toengage with the teeth of said rack, and a spring held in the hole formed in said sleeve and engaging said movable jaw member and said pawl, as and for the purpose specified.
In testimony whereof I have aflixed my signature in presence of two witnesses.
