ADOLPHUS S. RAGER, OF FREDERICK, MARYLAND.

COMBINED PIPE-HOLDER AND PIPE-VISE.

SPECIFICATION forming part of Letters Patent No. 486,124, dated November 15, 1892.

Application filed June 14,1892. Serial No. 436.659. (No model.)

To all whom it may concern.'

Be it known that I, ADOLPHUS S. RAGER, a citizen of the United States, residing at Frederick, in the county of Frederick, State of Maryland, haveinvented certain new and useful Improvements in a Combined Pipe-Holder and Pipe-Vise, of which the following is a Specification, reference being had therein to the accompanying drawings.

The objects of my improvement are to produce a simple and inexpensive machine adapted for use over Wells to retain a pipe while it is raised or lowered during the setting of a pump or of a pump-rod. The machine is also adapted for use as a pipe-vise to strongly clutch a pipe while screw-threads are cut upon its ends or upon any other part of its length. I attain these objects by the construction illustrated in the accompanying drawings, in which Figure lis a perspective view of a pipeholder constructed in accordance with my invention. Fig. 2 isa transverse vertical section on line of Fig. 3. Fig. 3 is a longitudinal vertical section on line y y of Fig. 2. Fig. 4. is a perspective view of the movable jaw of the combined pipe-holder and pipev1se.

In said drawings, A represents the baseplate, which may be of wood or metal, upon which is placed the stationary jaw B, secured to the base-plate by means of two vertical bolts b. Said jaw is also received within an inclosing metal frame A2, that is secured to the base-plate. The sides of the frame A2 have slots a2 made horizontally therein to guide the ends d of the head-block D of a carriage carrying the crescent-shaped blade E, used to clamp vertically between it and the stationary jaw B any pipe or rod that may be placed between said blade and jaw. Upon the cylindrical ends d of the head-block are mounted the outer ends of the sides D2 of the carriage, and the inner ends of said sides have horizontal grooves therein to receive the tenons e, projecting from the ends of the blade E. The sides D2 of the carriage normally rest upon the base-plate A and are guided either by the edges of a plate a, secured on top of a base-plate A, or by the slotted sides of the frame A2, or by both of these parts, as shown,

the nuts d2 upon the screw-threaded ends d of the head-block serving, also, to keep the carriage in alignment with the face of the stationary jaw. To move the blade-carrying or jaw-carrying carriage back or forth in its guideways, a screw F is made to pass through a screw-threaded hole in one end of the frame A2. Said screw has on its outer end a handwheel Gr, by which it can be rotated, and its inner end is shouldered or reduced in diameter and received loosely in a horizontal per-- foration in the center of a head-block D. The end of the screw beyond the front of said block is provided with a nut or head to retain it permanently united but loosely fitted in the head-block.

Although the front of the carriage and its blade E can be tipped up, as shown by dotted lines in Fig. 3, the head-block D of said carriage remains resting upon the guide-plate a and the screw F remains in a horizontal position. The hinging of the carriage substantially upon the end of the screw permits said carriage or its front blade to drop into engagement with any-sized pipe or rod that may be placed against the stationary jaw, and the screw permits any desired adjustment to be made.

When the device is to be used as a pipevise, the blade E is removed from the carriage and the jaw H is substituted, its tenons e being received in the horizontal grooves formed in the front ends of the sides D2 of the carriage. Said jaw H has a large V- shaped groove H2 in its front, and said groove has in its face a series of angular teeth h2, as usual. This jaw is of suitable size to enter in a chamber K kept for it under the stationary jaw B, a triangular block B2`being located under the jaw B, adapted to be received in the V- shaped groove H2 of the movable jaw H.

Having now fully described my invention, I claim- 1. In combination with the base-block and stationary jaw of a pipe-holder, the frame inclosing-` said jaw, a hand-screw retained parallel with the base-block, a head-block loosely mounted upon one end of said screw and forming the rear end of a carriage, the sides of said carriage pivoted to the head-block, a blade removably secured to said sides, and a IOO plate secured to the base-block between the of a blade-carrying carriage pivoted to the sides of the carriage, whereby the latter is head-block, and a blade rearwardly secured guided, substantially as described.

2. In combination with the base-block and 5 stationary jaw of a pipe-holder, the frame inelosing said jaw and having slots in its sides,a hand-screw retained parallel with the base-block, ahead-block loosely mounted upon one end of said screw and having its ends re- 1o ceived in guide-slots of the frame, the sides to said sides, substantially as described.

In testimony whereof I affix my signature in presence of lnwo witnesses.
