Specification of Letters Patent.
Application filed June 17, 1912.
Patented Mar. 18, 1913.
Serial No. 704,138.
To all whom it may concern Be it known that I, CARL .ROUBINEK, a subject of the Emperor of Austria-Hungary, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in renches, of which the following is a specification, reference being had therein to the accompanying drawing.
This invention relates to wrenches, and the primary object of my invention isto provide a nut wrench with a novel adjusting mechanism that permits of the adjustable jaw of the wrench being easily and quickly shifted and locked in an adjusted position.
A further object of this invention is to provide a wrench of the above type that is durable and highly efiicient for the purposes for which it is intended.
With the above and other objects in view, the invention resides in a novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.
Reference will now be had to the drawing, wherein like numerals denote corresponding parts throughout the several views, in which Figure 1 is a side elevation of a wrench in accordance with this invention. Fig.2 is a longitudinal sectional view of the same. Fig. 3 is a front elevation of the wrench partly broken away and partly in section. Fig. 4 is a perspective of the detached adjustable jaw. Fig. 5 is a longitudinal sec t-ional view of a portion of the wrench. Fig. i 6 is a perspective of the detached locking member. Fig. 7 is a similar view of an actuating lever, and Fig. 8 is a perspective view of a detached housing adapted to form part of the wrench.
A wrench in accordance with this invention comprises a channel shaped shank 1 that has the side walls 2 thereof provided with longitudinal slots 3, adjacent to the outer end of the shank. The outer end of the shank has a stationary or integral jaw 4 that is of a greater width than said shank. The jaw 4 presents a fiat gripping surface 5 at the front side of the shank.
The inner end f he shank 1 is reduced,
as at 6 and cut away as at 7 to reduce the weight of the shank. The inner end of the shank 1 is slotted, as at-8 and'the rear side of said shank, adjacent to the reduced end thereof has a longitudinal slot 9. The rear wall of the shank 1 at one side of the slot 9 is provided with teeth 10, and the same wall has transverse teeth 11 extending from the outer end of the slot 9 to a point in proximity to the jaw 4.
The adjustable jaw body is designated 12 and the jaw body is slidably mounted upon the front side of the shank 1. The jawbody 12. hasa fiat surface 13 confronting the gripping surface 5 of the jaw 4 and cooperating therewith in gripping the facets of a nut. The rear side ofthe adjustable jaw body 12 has a longitudinal tongue 14 extending into the channel of the shankl, and said tongue has a longitudinal recess 15, transverse alining openings 16 and 17 apertured lugs 18 connected by a pin 19, and a longitudinal rack 20. The adjustable jaw body 12 has a longitudinal slot 21, and the rack 20 is set to one side of said slot and extends from theinner end of the adis the camv end 27 of an actuating lever 28.
This lever has a barrel 29 loosely mounted upon a transverse pin 30, carried by the tongue 14, said pin extending through opening 31 provided therefor in said tongue. The end of the lever 28 extends into the slot 21 of the adjustable jaw body and is provided with a finger'piece 32 whereby said lever can'be actuated toswing the block 24 of the locking member out of engagement with the shank 1, whereby the adjustable jaw body can be moved upon said shank. The ends of the pin 22 are provided with revoluble rollers 33 and these rollers engage the Walls of the slot 3,
Arrangedwithin the opening 16 of the tongue 14 is a transverse pin 34 and revolu lily mounted upon the ends of said pin are rollers 35, similar to the rollers 33. The rollers are inclosed in the slots 3 by side plates 36 that are counter-sunk in the sides of the shank 1 and secured therein by screws or other fastening means, as at 37.
Secured to the front side edges of the ad justable jaw body 12 by screws 38 or other fastening means is a strap 39 that embraces the shank 1 and assists in retaining the adjustlable jaw body 12 in engagement therewit Arranged in the inner end of the shank 1 isa housing 40 that has apertured lugs 41 and 42. The apertured lug 41 is connected by a coiled spring 43 to the transverse pin 19 of the adjustable jaw body 12. The apertured lug 42 is connected by a coiled spring 44 to an apertured lug 45 arranged in the inner end of the shank 1, as best shown in Figs. 2 and 5. The housing 40 has a longitudinal groove 46 and the side of said housing is inclosed by a side plate 47. Revolubly mounted in the housing 40 is a pinion 48 and the shaft 49 of said pinion protrudes from the housing and is provided with a large toothed wheel 50 that engages the rack 20 and the teeth 10. The pinion 48 meshes with a rack-bar 51 that is slidably mounted in the groove 46 of the housing 40. The rack-bar 51 extends out of the housing and is provided with a finger piece 52, whereby said rackbar can be pulled outwardly. The housing extends into the longitudinal slot 9 in the rear wall of shank 1 and this slot assists in guiding said housing during its movement. The inner end of the rack-bar 51 has a longitudinal socket 53 and arranged in said socket is a coiled rectractile spring 54 that has one end thereof attached to the housing 40 and the opposite end thereof to the rack-bar 51. This spring holds the rack-bar 51 normally in the housing 40. The inner end of the housing 40 is cut away, as at 55 to provide clearance for the rack 20.
Arranged upon the sides of the reduced end of the shank 1 are handle plates 56 that are secured to the shank by screws 57 or other fastening means.
In operation, the actuating lever 28 is first moved to shift the locking member 23 out oflengagement with the shank 1. The finger piece 52 of the rack-bar 51 is next pulled outwardly to revolve the pinion 48 andthe toothed Wheel 50. As this wheel meshes with the rack 20, the rack and the adjustable jaw body 12 will be moved toward the inner end of the shank and simultaneous with this movement, the housin 40 is moved toward the end of the shank by reason of the wheel 50 meshing with the teeth 10. In other words, there is adoulole movement within the shank 1 which permits of the adjustable jaw body 12 being quickly shifted. The springs 43 and 44 properly balance and guide the housing 40 within the shank 1.
It is thought that .the operation of the wrench will be apparent without. further description, and I would have it understood that the structural elements are susceptible to such variations as fall within the scope of the appended claims.
