IMPBOVEMEN T IN PIPE-VISBS.

TO ALL WHOM IT MAY CONORN:

ABe it known that I, DAVID SAUNDERS', oi' Brooklyn', in the county of Kings, and State of' New York, have invented certain new and usefulimprovements in Pipe/Visita by which I mean vises `adapted to hold pipes or other round objects of diii'eren't sizes; and I do hereby-'declare that the following is a full and exact description thereof'.

My improved vise will hold pipes oi' diiferent sizes, and will let them in and out readily by a lateral movement instead of an end'movement, and allows the pipe to be held either upright or at any inclination required. The ability to hold pipes at diii'erent angles is important, because inA cutting threads on the ends, or otherwise treating pipes, it is desirabletohold them as nearly upright as may be, and while short pieces may be held,

under ordinary circumstances, directly upright, longer pieces require to be inclined to an extent depending on the length, as will beobvious. The introduction and removal of the pipes by a lateral movement, allow the pipes to be removed from my vise after a T-piece, an elbow, or other xture has been attached at each end. llhere have been many pipe-rises before known which possessed these qualities singly, but I know of none which possess them altogether. I employ a peculiarly constructed sliding-jaw as one portion of my vise, which is secured upon the operating screw in a manner which will be readily understood, and which aiiords increased strength and firmness to this important connection.

I will proceedlto describe what I consider the best means of carrying` out my invention. vThe accompanying drawings form a partei` this specification. l

' Figure 1 isa sectiomon the line S S in iig. 2.

Figure 2 is a plan view-of my vise, showing a pipe held within the jaws.

Similar letters of' reference indicate like parts in all the figures. 'Iints are employed only to aid in distinguishing parts, and do not indicate material. The material of the whole may be iron and steel.

A A1 is a casting adapted to be firmly secured upon the bench. by screws introduced through the holes a. Al is an upright flange, to the front face of which is applied a corresponding ange, B1, o f the casting, which contains and supports the effective portions of my vise. This casting entire I will designate generally as B. One ot its most important characteristics is the ample opening, H, provided in one side 'adjacent to thejaws, which seize and hold the pipe, and which is of suiiicient size to allow the largest pipes or other analogous articles to be introduced and removed freely by a simple lateral movement. The entire casting B audits connections turn in various positions, as required. The parts A1 and B1, which I have here termed anges, are finished in theform of nearly circular disks, and are bolted together by a screw-bolt, C, which passes through the centre, of each, by which the force withwhichthe flanges are held together may be graduated at will. When it is desired to change the position of the casting B, the screw C may be slackened, and after B is adjusted the screw C may be tightened again.v In many eases itwill suiiice to allow the screw C to be moderatelyv set up all of the time, so that thecasting maybe adjusted bythe force of a strong hand without touching the screw. Two pieces of hardened Ysteel having V-shaped dentated recesses, are fitted in the casting B in the position indicated by b1 b2. 'Ihe'spaceV between them is a little greater than the thickness of one of the pieces, and is sufficient to.allow the free entrance of a third piece of steel of similar thickness. Dl Dz are respectively the halves of a slide which-is traversed in the ways B2 B2, in the interior of the casting B, by means of the screw E, which is capped through the part B3, bolted upon the front of B, as represented. The parts of this compound slide Dl :D2 are firmly bolted together by the screw-bolts m. This slide carries'a piece of hardened steel, d, which is adapted to enter the recess or space before described between the similar pieces h1 b2. The general arrangement of the pieces b1 t2 and dis adapted to take hold of and firmly hold the pipes or otherround objects of different diameters, holding them with equal firmness, whether they be one-half inch or two inches in diam'- eter. When the combined slide DVD2 is driven inward to a great extent, a portion of its steel piece d is received between the steel pieces 61 b2, and when it is drawn back to its fullest extent the steel piece'ol is entirely clear from the pieces b1 b2, and allows the pipes to be introduced and removedv by a side movement, as `will be readily understood. It will be observed that the adjusting in the angular position oi' the entirecasting B and its connections, by turning it 'around upon the piece A, as above suggested, does not in any wise interfere with the relations ofthe working parts of the vise to each other. The screw E, provided with any approved means fortnrning it, is fitted with a strong head, or knob, El, at its inner end, uwhich is received within a corresponding recess finished in thc interiors of the two halves of the compound slide D1' D2. The neck between the' head E" and body, or threaded` portion of the screw El, is of smaller diameter, and receives strong'and nicely-finished internal lips on the parts D1 D2. The parts being properly turned and 'bored-to correspond with each other, and allow a. tight and easyr fitting, the halves are applied upon the head El before boing bolted together, and thc setting up of the screws m confines the parts ofthe compound slide together with the same rigidity as if the whole were one piece, while the Iconnection with the screw is stronger, and will endure more violent strains than ordinary fittings of this kind.

Having now fully described my invention, what I claim as new therein, and desire to secure by Letters Patent, is as follows: I claim the improved pipe-vise'herein described, turning on the axis C, and having the side opening H, to allow the introduction and removal of the work, the several parts being combined and arranged substantially as and for the purpose herein set forth.
