ANTON C. PAULSON, OF FARGO, NORTH DAKOTA.

ANVIL-VISE.

Application filed December 20, 1920.

To all whom it may concern Be it known that I, AN'roN C. PAULSON, a citizen of the United States, residing at Fargo, in the county of Cass and State of North Dakota, have invented certain new and useful Improvements in Anvil-Vises; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved anvil vise or clamp and one object of the in vention is to provide a vise or clamp so constructed that it may be connected with an anvil of a conventional construction, the body of the vise resting upon the upper face of the anvil and set-screws, being provided for engaging the sides of the anvil and seclilrely but releasably holding the vise in Another object of the invention is to so construct the body portion of this vise that a plurality. of sets ofjawsmay be carried by the body, one set of jaws moving transversely of the body and a second set including a cross bar which constitutes a station ary jaw and a movable jaw positioned beneath the stationary jaw and resting upon.

cams carried by the movable jaws which move transversely of the body so that this movable jaw which is positioned beneath the stationary jaw may be moved into and out of a clamping position by movement of the transversely moving jaws.

Another object of the invention is to so construct the cam elements and the movable jaw resting upon the cam elements that this movable 'aw which is removable will be prevented rom accidentally moving transversely from. beneath the upper stationary jaw or cross-bar. 1

Another object of the invention is to so construct this vise that the crossbar or relatively stationary jaw may be easily and quickly put in place or removed, and to further so construct the cam-operated jaw that it may be easily'removed when'dcsired.

Another object of the invention is to provide improved means for slidably connecting the transversely moving jaws with the body of the vise.

Another object of the invention is to so construct the transversely moving jaws that they may be operated by means of a common actuating screw which is in swivel 00111186 Specification of Letters Patent.

tion with a neck extension of one jaw and passes through a threaded opening formed in an upstanding arm carriedby a bar upon which the second jaw is mounted.

Another object of the invention is to provide an improved type of tool holder which includes a standard carried by the cross-bar or relatively stationary jaw and tool-gripping means at the upper free end of the standard.

Another object of the invention is to so construct the tooLholding means of the standard that the jaws forming part of the same will be yieldably held in gripping position. V

Another object of the invention is to provide an improved type of article holder adapted to be gripped between the transversely movable jaws, this article holder having jaw sections loosely connected and limited intheir movement away from each other.

Another object of the invention is to so construct this vise that the major portions thereof may be formed by casting thus permitting the device to be easily and cheaply produced.

This invention is illustrated in the accompanying drawings, wherein:

Figure l is a perspective view showing the improved vise in position for use with the cross-bar or stationary jaw in place.

Fig. 2 is a view similar to 1 showing the cross-bar and cooperating jaw removed and the separate article engaging device in place between the horizontally or transversely moving aws- Fig. 3 is a perspective view of the vise removed from the anvil and having the cross-bar and cooperating jaw removed therefrom.

Fig. 4 is a vertical. sectional view taken along the line 4- .1: of Fig. 1.

Fig. 5 is a vertical sectional view taken along the line 5-5 of Fig. 4L.

Fig. 6 is a perspective view of the body larged opening 6 formed in the wall 2. This opening 6 is deeper than the opening as clearly shown in Fig. (Sand a collar 7 provided about this opening 6 so that a wide bearing surface is provided. Arms 8 extend upwardly from the side walls 1 and 2 and these arms are formed relatively thick as shown clearly in Figs. 3 and 6 and provided with open ended sockets 9. Set-screws 10 are passed through threaded openings ll and extend into the sockets 9 so that a' cross bar to be hereinafter described may be securely but releasably held in these sockets 9. Setcrews 12 are passed through thread ed openings in the lower portions of the side walls for engaging the side faces of the anvil indicated in dotted lines in Figs. 1 and 2. It will thus be seen that by means of the set-screws 12, the vise or clamp may be securely but ,releasably held upon the anvil and may be readily removed when desired. This body portion is formed in a single casting and may thus be cheaply produced but at the same time will be very strong and durable.

The jaws 1.3 and 14 which are both movable jaws and are to move transversely of the body rest upon the web 3 and bridge the slot 5. The'jaw 13 is cast integral with a carrier bar 15 as shown in'Fig. 4 and is provided with a neck extension 16 for slidably fitting into the opening 4- of the w. 1 thus providing means for assisting in guiding sliding movement of this jaw 18. The

end of the carrier bar 15 is beveled as shov, n

at 17 and the web 3 is provided with a beveled face 18 at the inner end of the slot This carrier bar extends through the slot 5 and opening 6 and rests upon the wide hearing formed-by means of the collar 7 and a .26 are secured to the outer end of the neck 25 to hold the head 23 in the socket 2e and thus provide a swivel connection between the actuating screw 21 and'neck 25. It will thus be seen that when the actuating screw is rotated, one of the jaws will remain relatively stationary and the second will move toward the relatively stationary jaw. In

actual practice, one of the aws will at times remain stat1onary and the second jaw will move, while at other times, this will be reversed and in some instances both jaws will move. In any event, the two jaws will eventually be brought into contacting relation with each other or in management with any article which may be positioned between the two jaws. By having the two jaws constructed as shown, the jaw 13 carrying the bar 15 may first be put in place and the aw 1&- then put in place after which the actuating screw will be passed through the threaded opening 2 and the plates 26 put in place to connect the actuating screw with the jaw 14:.

In addition to the jaws 13 and l i, this vise is provided with a second set (it jaws which instead of having" relatively horizontal movement, will have relative vertical movement. This second set of jaws is provided with a. relatively stationary jaw in the "form of a rross bar 27 which [its into the sockets 9' and will be relcasablv secured in place by means oi the set-screws 10. A relatively movable jaw 28 is positioned beneath the jaw or cross bar 27 and is provided with :1 depending llange 52.) and with a cam block 30 which tapers downwardly as shown in the perspective view of Fig. 7. This cam block has its coi'ivcrging fat-es provided with grooves ill which are adapted to receive the ribs 32 formed upon the converging cam faces of the arms or cam elements 3 carried by the jaws l3 and ll. It will thus be seen that when the jaw 28 is put in place. beneath the stationary jaw or cross bar 27, its cam block will rest upon the cam elements of the jaws l3 and 14: and when these jaws are moved transversely through the medium of the actuating screw 21, the movable jaw 28 will receive upward or downward movement according to the direction in which the two jaws 13 and 14: are moved. If these jaws are moving toward each other. the jaw 28 will be moved upwardly toward a clamping' position but if the jaws l3 and l i are moving apart, the weight at the jaw 28 will cause it to move downwardly with the spreading of the two jaws l8 and 14.

in addition to constituting a statiomiry jaw, the cross bar 27 provides a base For a standard 3t which extends upwardly and is provided with a bent upper end portion 35 which extends horizontally and forms a neck or arm having a head at its free end. This head 35 forms a stationary jaw for a tool gripper and is provided with a recess which cooperates with a similar recess in a movable jaw 36 to form a socket 37 in which a tool may be placed. Pins 38 extend from the jaw 35 through openings formed in the movable jaw 36 and each of these pins carries a spring 39 for engaging the movable jaw, nuts ll) being screwed upon the threads ed end portions of these pins so that the springs may be placed under compression and. thus the movable jaw yieldably held. in a clamping position. The pins 38 in addition to mounting the movable jaw and springs, also serve as means for guiding movement of the movable jaw.

It is desired to provide means for holding articles between the jaws 13 and 1.4 and there has therefore been provided an article holder in the form of jaws 41 and 42 which have their contacting faces out to provide recesses registering to term sockets 43. These sockets 43 are of different sizes so that a bolt or other similar article may be placed in a socket of a convenient size. The jaw 42 is provided with end extensions 44 which extend across the end of the jaw 41 and these armsor end extensions 44 are provided with slots or sockets 45 to receive the pins 46 which extend from the ends of the jaw 41. From an inspection of Fig. 8, it will be seen that. the slots 45 are elongated thus permitting the pins to have movement in the slots when i it is desired to move the jaw 41 out of contact with the jaw 42. At the same time, the jaw 41 is prevented from becoming entirely separated from the jaw 42.

When this device is in use, it will. be placed upon the anvil as shown and an article such as a metal bar may be gripped between the jaws 13 and 14 and bent down through the slots 47. If so desired, the bar may be simply held between these two jaws and either cut or any other desired operation performed. If it is desired to form a head upon a metal rod, the rod will be passed through the usual opening provided in an anvil and will be passed up through the opening 48 in the carrier bar 15. The heated upper end portion of this red will be positioned in one of the sockets 43 of the work holder shown in Fig. 8 and the two jaws 13 and 14 then brought into tight binding ongagement with the work holder. A rivet head can then be formed by simply beating down the heated end of the rod. If it is desired to make use of the clamp having the jaws moving vertically, the cross bar 27 and movable jaw 28 will be put in place.

The article to be gripped will. be placed between the movable jaw 28 and the stationary jaw or cross bar 27 and the actuating screw 21 then rotated to bring the jaws 1.3 and 14 toward each other. This will cause the movable aw to be moved upwardly and the article will be securely gripped. \Vhen the actuating screw is rotated in the opposite direction, the aws 13 and 14 will spread and the movable jaw will move downwardly from the stationary jaw or cross bar thus releasing the article. If it is desired to make use 01 the tool holder carried by the stand ard of this cross bar, the punch or other tool which it is desired to make use of will be placed in the socket 37 and will be held over the work which will be either gripped between the clamping jaws 13 and 14 or may be placed in the holder of Fig. 8. Of course, if so desired, the movable jaw could be left in place and the device to be operated upon held by means of this jaw. When it is no longer desired to make use of this vise, the set'screws 12 will be released and the device can be bodily removed from the anvil.

It will thus be seen that there has been provided a vise so constructed that it can be easily and quickly put in place and further so constructed that most of the parts may be formed by casting.
