JAMES L. DILLON, 0F LEAVEIXTWORTH, KANSAS, ASSIGNOR OF ONE-HALF TO FREDERICK L. WENDLER, 0F ST.'LOUIS, MISSOURI.

PIPE-VISE.

To all whom it may concern:

Be it known. that I, JAMES L. DILLON, a citizen of.tl1e United States, residing at Leavenworth, in the county of Leavenworth and State of Kansas, have invented certain new and useful Improvements in Pipe- Vises, of which the following is a specification, reference being had therein to the accompanying drawings. I This invention relates to .a device for holding pipe or similar articles or materials while being worked on, and it provides such a device so arranged that it can be mounted firmly on a bench or other base or support without material alteration thereof.

One of the objects of the invention is so "to form such a device that it will securely hold pipe orother round material, and also material of other shapes, of varying sizes up to the maximum that'can be taken by its aws.

It also is an objeet ofthe invention to provide in such a device means whereby/the material, or article held maybe brought quickly between or against the jaws I or equivalentparts and great leverage easily exerted in clamping inplace what is held.

When read in connection with the description. herein, the details of;,construction and arrangement of parts contemplated by the invention will be apparent from the accompanying drawings, formingpart hereof,

wherein an embodiment of the invention is disclosed, for purposes of illustration.

what now is considered to be a preferable While the disclosures herein exemplify embodiment of the invention, it is to be understood that it isnot the intention to be limited necessarily thereto in interpretation. of the claims, as modifications and adaptations within the limits of the claims can be and spirit of the invention. 7

Application filed November 25, 1919. Serial No. 340,617.

Having'more particular reference to the drawings, 7 designates a flat base member arranged to be secured firmly to a bench'or plane of that member. i v

One or more pairs .of jaws are secured to one sidegof the standard; their opposed edges or surfaces are inclined with respect to the plane of the standard in such manner that, the distance between them increases from the standard to theirouter ends whereby a Wedge-shaped space isiafforded, and

those edges or surfaces are formed with,

teeth 11 or otherwise roughened to prevent slipping of the article or material .held

thereagainst' a In the embodiment of the invention disclosed herein, two pairs ofsuch jaws are emposed at right angles with'respect to the ployed, and they are secured to the standard I by integral'pi'ns 12 extending therethrough and having their headsupsetagai-nst the face of the standard opposite to the jaws, but other numbers or pairs of jaws may be used and secured to'the standard tin-that or other suitable manner. v f In order that the pairs of jaws and the membersof each pair may be placed differ- .ent distances from one another, and also to provide for'varyingnumbers of pairs, the standard may beformed with sets of differ ventially sp-aced and placed holes and the jaws with'pins 1.4 arranged'to extendtherethrough and to beheld by'nuts 15 on their. threaded ends, as :shown by Fig. fl.

Two side-members" or plates 16, spaced from and in substantially parallel relation to each other," and constituting a frame; for supporting operative vparts of the device, extend from the {side of the standard opbers has an integral laterally-extending flange 17 by which it is held onthe standard by bolts or other suitable fasteners 18 eX-.

tending theretlrrou'gh.

Ordinarlly, the ,frame will remain same .place on the standard. However, in

. posite to the jaws, andeach of ,these mem-' .orderto meet unusual requirements, as-when the location of-the pairs of jaws maybechanged, the standard may have a plurality of sets of holes 19, as seen in Fig. 4, for reception of fasteners 18, which will permit the shifting of the frame, or the employment of a plurality of frames and parts carried thereby if that is necessary.

.A shaft 20 is journaled in the frame members 16 adjacent to the standard, and one or more winding members or wheeis 21 are fast on that silaft. Each of these wheels has peripheral recesses or seats 22 conforming in shape and size to and arranged to take a flexible binding member such as a chain 23, abutments 22 engaging the links lying flat and preventing the chain from slipping off the wheel.

One portion of the chain, as its end link, is made fast to any suitable portion of the device, as to a frame member by a fastener 24. When the device is in use, the free portion of the chain is extended over the article or material to be drawn against the jaws and over the wheel and into its seats, slots 25 permitting the chain to be disposed through the standard.

The present embodiment of the invention contemplates employment of two chainwheels 21, one on each end of the shaft 20 outside of the frame members, and two chains, but a greater or less number may be used, if necessary. If more than two wheels and chains are used, the shaft 20 may be longer to accommodate them; and, if the shaft is so lengthened as to require support in addition to that afforded by two frame members, one or more additional such members may be secured to the plate by fastenings through extra holes 9.

A gear 26 is fast on shaft 20 between the frame members 16, and it is in mesh with an intermediate gear 27 rotatably mounted be tween these members on a shaft 28. A shaft 29 is carried by the frame members near their free ends, and a handle member 30 is fulcrumed on that shaft between those members, the handle member having a toothed terminal segment 31 in mesh with the intermedi ate gear. The free ends of the frame members 16 are formed with teeth affording segmental racks 32 for engagement with a detent 33 on the endof a slide 34, which latter is connected with a member. 35 pivoted on the free end portion of the handle member, the detent being kept in engagement with the racks by a spring 36 between the member 35 and the handle member.

n When an article or material, such as a pipe for example, is to be held by the device, it is brought against or between the may be passed through the loops.

jaws, and the chains are passed thereover and over the chainwheels and into the seats thereof; or, if the chains already are in loop form and over the wheels, the article 7 p The handle member at that time is either in its median position or swung toward the side on which the chains are disposed on the wheels. While the parts are in such positions, the chains are drawn against the held article as tightly as may be by hand. Then the handle is swung, and by this movement, through the instrumentality of the segment and gears, the chain-wheels are rotated, the chains drawn more tightly against the article, and the latter clamped against or between the jaws. The detent and racks will prevent reverse movement of the handle and loosening of the hold on the article.

The chains may be released from tension on the article by imparting reverse movement to the handle after releasing the detent from the racks by pressing the pivoted member 35 against the spring 36, and they may be further loosened thereafter by moving the chains in or from the peripheral wheelseats. Then the article may be withdrawn longitudinally from the device, or laterally therefrom after freeing the chains entirely from it.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A vise comprising a support, an artiole-engaging element on one side of said support, spaced arms extending from the other side of said support, a winding member journaled on said arms, a flexible binding member arranged to be engaged with said winding member and to pull an article against said engaging element, and means whereby said winding member is rotated.
