Home y Invenior I Patented Get. 24, 1933 eme STATES PATENT OFFICE 1,931,934 v VISE AND SECURING MEANS THEREFOR Joseph Norman, Beverly, Alberta, Canada Application April 28, 1933. Serial No. 668,431 3 Claims. (01. 81-41) This invention relates to vises, and more par ticularly to pipe vises and means for securing such vises to a bench, or to a post, or rail, when necessary.

One of the salient objects of the invention is to provide improved means for effectivelysecuring the vise to a post, or rail as is often required when a bench is not accessible.

The invention together with its numerous objects and advantages will be best understood from a study of the following description, taken in connection with the accompanying drawings.

It is to be understood that it is in no wise intended to restrict the invention to the specific 5 embodiment illustrated and described other than may be necessary to meet the requirements of the prior art and the scope of the appended claims.

In the drawings:

Figure 1 is an elevational view of the vise and securing means therefor showing the pipe in posi-- tion, and the vise secured to a rail.

Figure 2 is a plan view of a nut.

Figure 3 is a fragmentary sectional elevational view showing the opening and slot provided in the base plate of the device for receiving an end of the clamping chain.

Figure 4. is an end elevational View showing the vise secured to the rail.

Figure 5 is a fragmentary sectional view through a portion of the base plate showing one type of cleat associated therewith.

Figure 6 is a fragmentary sectional View through the base plate showing a second type of cleat.

Figure 7 is a plan view of the base plate.

Figure 8 is a plan view of a collar and hook associated therewith.

Figure 9 is a sectional view taken at right angles to Figure 3 showing one of the projecting ends of the clamping chain engaged in notches provided therefor in the base plate.

Figure 10 is an end edge elevational view of the base plate and showing the jaws mounted thereon.

Referring to the drawings by reference numerals it will be seen that 10 indicates the base plate of the vise, and at one end thereof the base plate 10 is reduced and offset upwardly at 11.

The free end of the offset 11 is provided with an eye or opening 12. The plate 10 is also provided adjacent the offset 11 with a cleat or rivet 13 of the type shown in Figure 5, and nearer to its transverse center line said plate is provided with ,laterally spaced rivetsor cleats 14 of the type shown in Figure 6. Cleats 13 and 14 have conical or pointed heads to bite or pierce the support, in the present instance the rail 15, as will'be clear' from a study of Figure 1.

At the end thereof remote from the oifset 11' the plate 10 is provided with two jaws 1616 which are V-shaped at the upper end and provided'with teeth which engage the pipe 17 when it is laid upon the jaws. The jaws are spaced apart and located between the jaws inwardly from one edge of the plate is an aperture 18. In'line with the aperture 18 adjacent the edge of the plate farthest remote from said aperture is an aperture 19 that merges into a slot 20. On the under face thereof the plate 10, at opposite sides of the slot 20' is provided with notches 21.

The aperture 18 accommodates a threaded shank' 22 to one end of which is pivoted one end of the vise chain 23; Engaged with the shank 22 is a nut 24 whichwhen screwed up on the shank 22 has anend thereof engaging aseat 25 provided V therefor at the bottom of the aperture 18. Nut 24 is provided with a handle 26 to facilitate turning of the nut. The aperture 19 is adapted to receive the free end of the chain 23 and the pivot pins 27 of the chain. The pivot pins 27 are wider 3 than the slot 20 so as to engage the notches 21 as suggested in Figure 4.

Through this arrangement of parts it will be seen that a pipe can be laid on the jaws 16 and p the chain 23 ispassed over the pipe. The proper pivotpin 27 of the chain isengaged with the notches 21 and the chain is tightened about the pipe by screwing the nut 24 upwardly on the stem 22.

In order to fasten the device securely in position on for example, a support such as the rail 15, there is provided a chain 28 which, in the present instance is the same type of chain as that used in securing the pipe to the vise. The chain 28'as shown is also pivoted at one end to a shank 29 somewhat similar to the vise shank 22. Threadedly engaged with the shank 29 is a nut 30 of a type similar to the aforementioned nut 24 and this dle 31.

Engaged about the shank or stem 29 is a collar 32 of the type clearly shown in Figure 8. This collar is provided with an opening 33 for receiving the shank or stem 29 and a seat 34 about nut 30 is also provided with a hanthe opening and with which one end of the nut 30 is engaged when the same is tightened on the stem 29.

Collar 32 is also provided with a slot 35 and pivoted within the slot through the medium of a pivot pin 36 is the shank of a hook 37 adapted 1'10,

to engage the eye 12 of the base plate 10 in a manner clearly shown in Figure 1.

The free end of the chain 28 is adapted to work through an opening 38 provided therefor in the base plate 10. Extending from the opening 38 is a slot 39, and on the top face thereof at opposite sides of the slot the plate 10 is provided with notches 40 for reception of the pivot pins 41 of the chain 38 to secure the chain against being drawn downwardly through the opening 38 when the nut 30 is tightened.

As will be clear from a study of Figure 1 when it is desired to secure the device to the post or rail 15 the plate 10 is disposed against one side of the rail 15 while the chain 28 passes about the rail 15 and has its free end extending through the opening 38 of the plate 10. The hook 37 is engaged with the eye 12. The proper one of the pivot pins 41 of the chain is engaged with the notches 40 and the nut 30 then tightened on the stem 29 to draw the chain taut and to force the collar 32 toward the pivoted end of the stem or shank 29 thus drawing the penetrating points of the rivets into engagement with the rail 15 and thereby secure the vise in position on the rail and the plate 10 against creeping.

Having thus described my invention, what I wish to claim is: l

1. In a device of the character described, in combination, a base, jaws on the base, said base between said jaws being provided with spaced openings, a chain extending through one of said openings, a stem on one end of the chain extending through the other of said openings, means for engaging the chain at the under side of the base adjacent the first named opening, a nut screw threadedly engaged with the stem for exerting pressure on the chain to hold the article, being clamped, to the jaws; a clamping chain,

-means for engaging one end portion of the clamping chain with the top side of the base intermediate the ends of the latter, an extension projecting from said base and provided with an eye, a stern on the free end of the clamping chain, a collar slidably engaged with the stem of the clamping chain, a hook pivotally engaged with the collar and adapted to engage with said eye, and a nut threadedly engaged with the stem of the clamping chain for exerting pressure on said collar and the clamping chain to hold a base plate to the support to which the base plate is adapted to be clamped.

2 The combination with the base of a pipe vise, of an extension on said base at one end thereof provided with an eye, said base being provided with an aperture intermediate its ends, a clamping chain for securing the base to a support, the chain having an end thereof extending through said aperture, means for engaging said end of the chain at the side of the base adjacent said aperture, a stem on the free end of said chain, a collar engaging said stem, a hook pivotally connected to said collar and engageable with said eye for securing the chain about the support to which the base is to be secured, and a nut on said stem for exerting pressure on the chain and collar to secure the base to the support.

3. In combination with the base of a pipe vise, said base having an offset projection at one end provided with an eye, and being also provided with an aperture remote from said projection, a chain having an end threaded through said aperture and provided with means for engaging one side of the base adjacent said aperture, a hook adapted to engage the eye of said projection, and means operatively connecting said hook with the free end of said chain.

JOSEPH NORMAN.
