UNITED STATES GEORGE CLIFFORD HILL, OF LO'S ANGEL ES, CALIFORNIA.
TOOL FOR SEATING AND UNSEATING STUD BOLTS.
Application filed April 11, 1923. Serial No. 631,454.
To all whom it may concern:
Be it known that I, Gnonon CLIFFORD HILL, a citizen of United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Tools for Seating and Unseatin Stud Bolts; and I do hereby declare the ollowing to be a full, clear, and exact descriptionof the invention, such as will enable others, skilled in the art to which it appertains, to make and use the same.
This invention relates to tools for seating and unseating stud bolts, and particularly to a tool with a shank tubular at one end for receiving the end of a bolt with a binding pawl adjacent the tube, and the other end of the shank provided with means for turning the shank to seat or unseat a stud bolt.
.The object of the invention is to provide a tool that may be carried in a small space and contain in itself all the parts necessary for screwing stud bolts into the heads of'cylinders or in other places, and that may .be used equally as well for unscrewing the stud bolts from such positions, and without injury to the protruding threaded end of the stud, in either process.
A further object is to provide a tool for seating and unseating stud bolts in places diflicult of access with ordinary wrenches.
A still further object is to provide a tool for seating and unseating stud bolts, with a shank of any desired length, having a hole extending longitudinally into one end of the shank, and a pawl mounted to operate at right angles with the bore, said pawl having a lug or handle on one end for releasing it from a tightened position against a stud; theoth'er end of theshank provided with a hole at right angles therethrough for a-turning bar and a head for turning the shank if desired, by any suitable wrench.
In my drawings, like numerals on the different figures refer to like parts of the tool.
Figure 1 shows a front elevation of the tool complete;
Fig. 2 shows cross section of the lower part, with a stud bolt' Fig. 3 shows a side elevation of the lower end of tool, and
Figs. 4, 5 and 6 show cross sectional views taken at AA of Fig. 1, with the pawl in different positions.
One or more are provided through the upper end of shank 1 for receiving a short turning bar 15 for turning the shank and the stud in either direction to right or left, for seating or unseating the stud from its bed block 11, the pawl'being operative in either direction as shown in Figs. 5 and 6, for bindin against the stud,v and entirely withdrawa le from the bore as to permit entrance of the stud into the bore. The bar 15 may be removed from shank 1 and the entire tool easily packed in small space. The top of shaft 1 is provided with a hexagon or other head 16 for are extension socket wrench.
I claim:
In a tool for seating and unseating stud bolts, a tubular shaft, a nut formed on one end of said shaft, said shaft bein provided with a plurality of holes extendin therethrough at right angles to each other and at rig t angles with the shaft and adjacent said nut, an ad'ustable rod adapted to slidably en age eit er of the holes for turning the sha t; the other end of said shaft being provided with spaced jaws extending at right angles thereto, the opening between said jaws extending into the bore of said shaft, an eccentric pawl mounted rotatively transverse holes as 13 and 14 on an axle, held between the (laws, one edge of the pawl when so mounte extending to the 'bore inthe shaft and having a'serrated,
I curved face, the other edge of the pawl provided with a handle for operatin the same, the serrated portion of the paw being eccentrically mounted with respect to the earing axle and the bore in the shaft, for tightemng against said hole when the shaft is turned in either direction after the hOIQ'iS 10 turned as desired.
In testimony whereof I afiix my signature.
GEORGE CLIFFORD HILL.
