QUICK-ACTIN G MULTIPLE-PURPOSE IMPLEMENT.

and State of Virginia, have invented certain new and useful improvements in Quick-Acting Multiple-Purpose Implements, of which the following-is a specification.

This invention relates to quick acting multiple purpose implement, and has for its object to provide a hand implement or tool adapted for use for various purposes, such as a wrench for nuts or pipes, a shear, a or for various other purposes where great stress in limited space is required.

A further object of the -invention is to provide an organization having a great range of adjusta-bility, with movable jaws and means for applying a great degree of stress to the jaws by the application of manual power to the levers.

A further object of the invention is to provide a device having interchangeable jaws and parts'whereby the implement, as an entiret may be quickly, and conveniently changed from performing one utility to another.

With these and other objects in view, the device comprises certain novel units, elements, parts, combinations, vmechanical movements and functions as will be hereinafter more fully described and claimed.

In the drawings Figure 1 is a. view of one embodiment of the invention shown in section.

tion shown in section, the jaws showing in dotted llnes its utility as a pipe wrench.

, Like characters of reference indicate corresponding parts throughout the several views.

In the type of implement shown at Figures 1 and 2, the body portion comprise side plates 10 and 11, which are preferably, though not necessarily, joined in a unitarv structure by a cross bar 12. To this body, comprising the side bars-1O and 11, a hans $113, 13, 1s secured rigidly but adjustably.

e of a rosette connection shown at 14 in Figure 2, nuts 15 and 16 mountedupon the pintle 17, which pintle rotates in the body and carries therewith the nuts 15 and 16, but the compremion of the nuts upon the handle 13 by reason of the rosette joint maintains such handle in rigid connection with the body.

Between the side bars 10 and 11 a jaw member 18 is removably secured by the bolts 19 and 20,-whereby the said jaw member 18 may be removed and replaced by a jaw for a different purpose.

The pintle 17 extending as it does through the side bars 10 and 11, is provided at the side opposite the handle 13 with the lever 21 connected to the pintle by a rosette joint 22, a nut 23 being employed for securmg the necessary compression. Between the side bars 10 and 11 a link 24 is rigidly secured to the pintle 17 in any approved manner as by the" keys 25 formmg wlt-h the lever 21 an adjustable bellcrank lever. This link is preferably of channel formation as indicated by the web 26 in Figure 1,, but it is to be understood that the link is not limited to such channel structure.

The link 24 is provided with a pintle 27 upon which is pivoted a pawl 28. The pawl 28 is provided with a nose 29 proportioned and positioned to engage the rack 30 of the slidable relative to the side bars 10 and 11 by the tongued and grooved formation indicated at 32.

A spring 33-is secured between the side bars 10 and 11, and has its end 34 bearing under the web 26 of the link 24, tending to raise such link from the position shown at Figure 1. A spring 35 is also secured between the side bars 10 and ll and bears upon the pawl 28. The pawl 28 is provided adjustability is accomplished by meanswith a finger 36 positioned to engage a pin 37 when the link 24 is swung up to dotted line position, thereby flexing the spring and lifting the pawl out of engagement with the rack 30. In this type the spring 33. may be much heavier and exerts more stress than the spring 35, whereby when the lever 21 is released the spring 33 tends to move thelink 24 and lever 21 as an organized structure about the fulcrum 17 to dotted position,

and by reason of the engagement of the finger 36 with the pin 37 to disengage the pawl 28 from the rack 30. So that withthe return movement the jaw'31 may' be moved with a step-by-step movement by the oscillation of the lever 21 andlink 24. A spring 38 is secured in an approved manner to the pintle 17 as by bem inserted through said pintle, and is provi ed with a nose 39 normally engaging the teeth of the rack 30 .until the lever 31 has been swung to its disengaging limit, whereupon the nose 39 is also released from the teeth of the rack, the

rack then being entirely free to be manually removed and re laced.

As shown at *igure 3, the side plates engage the jaw 18 by the use of the same vbolts 19 and 20. The handle 41 of this emis ivote between the side plates at 43,

an at 44 pivotally connected to the pawl 45. The spring 46 tends to move the lever 42 to such position as to release the pawl from engagement with the rack 30, a finger 47 and pin 48, corresponding to the finger 36 and pin 37, being employed. A spr1ng 49 holds the awl 45 normally to its work, but is adapted to be released by the movement of the lever 42 .to its dotted line position either manually or under the stress of the spring 46, the relative tension of the springs 46 and 49 being such that the spring 46 overstresses the spring 49.

In the type shown at Figure 3, the aw 18 is provided with a socket 50 and the aw 31 with a socket 51. Either one of these sockets .50 or 51' is ada ted to receive thee punch unit 52 shown at igure 4, while the other receives the screw 53 of the mandrel used as a punch. a

. In'the modification shown at Figure 6 a more compact organization is provided.

' The jaw 56 here shown is a shear jaw, but capable of taking any of the other forms shown in any of the other figures as sildable betweenthe side plates 57. Araok 58 is carried by this jaw member and a pawl 59 is pivoted between the side plates 57 for holding the jaw member 56 in adjusted position. The jaw member 60 is connected with and operated by the lever 61 by means of the arm 62 forming therewith a bellformation of the pawl is such, however, that when the pivot 65 moves forward opposite the direction of the arrow to open the sliding jaw 60 such pivot engages back of the paw 59 and moves such pawl against the tension of the spring 66 to release its engagement with the rack 58'. Thus when the lever 61 is moved opposite the direction of the arrow to its inoperative limit, the pawl is-automatically released, releasing thereby the jaw 56 for manual adjustment or replacement.

In the embodiment shown at Figure 7 a block. 68 is slidably mounted between t e side plates 69. A jaw 70 is also slidably mounted between the side plates and provided with a rack 71. The sliding block 68 carries a pawl 72 pivoted thereto at 73 with a spring 74 for holding such pawl yieldingly in engagement with the rack. The lever 75 through the medium of the link 76 reciprocates the block 68 and therewith the awl 72 advancing the jaw 70 with a stepy-step movement, or when the jaw has come into engagementwith a body between such jaw and the stationary jaw 76 exerting stress thereon. The pawl 72 is provided with acam shoulder 77 in position to engage a pin 78 when the lever has been moved to its ino erative limit, thereby releasing the pawl 72 trom engagement with the rack 71.

In each of the embodiments either or both of the jaws are readily removable orreplaceable by any of the several types of jaws shown in any of the several figures whereby the multiple purpose of the implement is made available.

It will be noted also that the toggle joint connecting. thelever in the severab types -may be secured by its oscillation.
