2 Claims. (Cl. 81-41) This invention relates to a vise and in particular to means for securing a vise to supports having different configurations.

In construction work, plumbers. and other artisans use vises for holding conduit such as tubing'and piping during cutting, threading and other operations thereon. In construction such as house building, vertical supports such as stud members are available during the early stages for attachment thereto of the vise. At a later stage of construction, i. e., when the wall material has been erected or installed, such rectangular cross-section stud members are no longer exposed and often only Patented Jan. 22, 1957 removably securing said element to a support; and means supports such as circular cross-section posts or pipes ferent supports are available in the various areas.

The necessity for having a number of vises available, each adapted for attachment to a different shaped support, is considerably disadvantageous. The vises are relatively heavy and cumbersome so that transport of a number of them, unless necessary, is generally to be avoided. This results, at times, in not having the proper vise available. Further the appropriate support for a given vise may be unavailable without the previous knowledge of the workman, thus involving expense and delay in obtaining the correct vise.

The principal feature of this invention is the provision of a new and improved vise adapted for securing to supports having dilferent configurations.

Another feature of the invention is the provision of a vise having a plurality of base elements, each adapted for securing to a support having a diiferent configuration.

A further feature of the invention is the provision of a vise having a first base plate adapted for attachment to a support having two normal plane surfaces and a second base plate adapted for attachment to a support having a cylindrical surface, with registering means to hold said base plates in juxtaposition when in use.

A still further feature of the invention is the pro; vision of a vase having a plurality of support-securing base plates and new and improved hinge means whereby at least one of said base plates is hingedly secured to the vise to allow mating engagement with another base plate.

Yet another feature of the invention is the provision of a vise having a flexible means for securing the vise to a support and adjustable connecting means to provide forcible positioning of one end of the securing means.

A still further feature of the invention is the provision of a vise-support-securing means comprising a plurality of base elements each adapted for securing to a support having a different configuration and with means for removably securing at least one of the base elements to the vise.

A yet further feature of the invention is the provision of a support-securing base element having means for to secure a vise removably to said base element.

Other features and advantages of this invention will be apparent from the following specification and the drawings in which:

Fig. 1 is a plan view of a vise secured to a rectangular cross-section support and provided with adjustable chain-tightening means;

Fig. 2 is a fragmentary plan view of a vise with a second base plate hingedly attached and positioned for securing the vise to a circular cross-section support;

Fig. 3 is a side elevation of the base element hinge means;

Fig. 4 is a rear elevation of the base element hinge means;

Fig. 5 is a fragmentary elevation of a vise threadedly secured to a removable base plate secured to a circular cross-section support;

Fig. 6 is a front elevation of the removable base plate; and

Fig. 7 is a bottom view of the removable base plate.

The vise 10 as seen in Fig. 1 is provided With a body. member 11 having :a side portion 11a and a first base plate 12. Jaw members 10a co-operate with a threaded rod 10b and handle 100 to hold conduit such as piping or tubing. The end link 30a of a chain 30 is secured to adjustable connecting means 31, which is attached. to body-member side portion 11a. To install the vise, the chain 30 is extended around a support member, in this instance, a rectangular cross-section -stud 20, and the free end of the chain is engaged with a hook the position shown in Fig. 2, wherein the second base plate flat rear surface 15a is in juxtaposition with fiat portion 12b of the first base plate. Two dowel pins 16 are attached to second base plate 15 and extend from surface 15a so as to'engage two holes 12b in the first base plate 12 to maintain the tWo base plates in register. Two pairs of V blocks 15b are mounted on the front surface of the second base plate and spaced to form a notch for receivably engaging a circular crosssection post 21. To secure the vise to the post, the chain 30 is extended around the post and its free end secured to the hook 32, as described above.

In the embodiment shown in Figs. 1 and 2, an adjustable chain-connecting means 31 is provided, comprising a bracket 31a, which is attached to the side portion 11a. The bracket is provided with a hole 31a having a diameter slightly greater than the diameter of the threaded shank portion of an eyebolt 31b, thereby allowing the eyebolt to move freely longitudinally within said hole. A chain link 30a is attached to the eye portion 31b of the eyebolt and the threaded portion of the bolt extends through the bracket. A nut 310 is threaded thereon and the eyebolt is thus retained in hole 31a between the enlarged eye portion 31b and the nut 310. When the vise is mounted on a support, such as stud 20 or post 21 and the chain extended therearound with its free end in engagement with the hook 32, additional holding force on the chain is readily obtained by tightening the nut 310 against the edge of the bracket 31a so as to draw the eyebolt through the hole 31a. Only a small amount of tightening is required as the chain 30 may be extended around the support tightly when attaching the free end to the hook 32.

An improved hinge means 17 is provided to facilitate alignment of the base plate so that the dowels 16 will register readily with the holes 12b when the base plates are pivoted into juxtaposition. As can be seen best in Figs. 3 and4j the hinge means comprises two studs 18', one threadedly secured to the first base plate and the other threadedly secured to the second base plate. isp'rovidedwith a diamet'ricalslot 18a"'extending from the. top of the: stud head 18:: longitudinally downward and into the shank portion; The width :of' the slot is slightlygreater than the thickness of the metalplate 19,,

which is inserted freely therein. Each of'the stud heads is provided with a transverse hole 186: andplate 19 is provided" with two mating holes 19a," one positioned in one end portion and the other in theopposing'endportion; In assembling the hinge, the two studs 18" are positioned sothat the slots 18a align with each other plate'19then" being inserted therein so 'that holes 19a: and 18a are in'alignment'a-t'which timepins 18B are inserted through said holes and held in engagement with the stud heads studs 23. The base 22 is secured in turn to a circular cross-section post by chain 30.

A's best' can be seen in Figs. 6 and 7, the base 22 is-.

providedwith a top portion 22a-havingtwo bosses 22a, oniits 'lower surface. A plurality of threadedholes 122a" is provided in. eachiof the bosses;thepositioningof the: holes being suchthat they will align with holes normally The base 22.is=

provided in the standard vise" bases. further provided with two sets of'projectingporti'ons 22b dependingfrorn and extending normally to the. lower.

surface. of portion. 22a. The surfacesv 22b of the pro! jecting, portions are angularly disposed so as to form a notch configuration adapted for engagement with the circular. cross-section support. A pair of centrally positioned hooks 22c and22c are integrally attached to the.

base22 and project a short distance'from the side.

In use, the base plate 22 is positioned against the circular cross section support with the notch forming surfaces 22b in engagement therewith. One end of the chain 30 is: inserted into one of the hooks, for example 22c, and. The chain is then drawn:

extended around the support. tightly and its free end engaged with the hook 220. To assure a tight and secure engagement ofthe base 22 with thesupport, a wedge 24 may be placed between the chain. and the support and driven'into this space, thereby taking.

up any slack present.

Any standardvise having holes in its flat-surfaced .base positioned corresponding to any pair of those provided in-the base 22 may be quickly and easily mounted on the Each stud The hinge further allows removal of the second" base 22 either prior to mounting the base 22 on the supportor when so mountedf As shown in Fig: the vise 10 is positioned so that theiflat side portion 12b is in juxtaposition with the upper surface of the top portion 22a of second base plate 22. Holes 12b in the portion 12b are positioned to align with holes 22a" in the second base plate. Bolts 23 are then inserted through the holes 12b and threaded into the holes 22a" until the heads of the bolts 23 bear against the base plate 12, thus tightly securing the two base plates together.

To prevent loss-orimisplacementl of thebase plate 22, it may be attached byfiexible means such as a chain to the vise or may be hingedly attached'by means such as the hinge means 17 'previously;described..
