AUNITED STATES PATENT OFFICE.
I-IOLCOMBE RUDEBOCK, OF PITTSBURG, PENNSYLVANIA.
rms-WRENCH.-
SPECIFICATION forming part of Letters Patent No. 624,253, dated May 2, 1899. Application inea August 18,1888. Seriana. 888,880. (roman.)
' ication, reference being had therein to the accompanying drawings. 8
My invention relates to certain new and useful improvements in adjustable pipewrenches.
My invention aims to construct a Wrench of this character which'is particularly adapted foruse upon polished pipe of 'every description to preventin jury to the polished surface. v Myinvention consists of a screw-threaded metal bar of suitable shape, having a suitable handle secured thereto, (not shown,) a collar and adjusting-nut mounted thereon for adj ustin g the metallic wrenching-band,and suitable means for securing the band at both ends to the bar.
My invention further consists in the novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the claims hereunto appended.
In describing the invention in detail reference is had to the accompanyingdrawings, forming a part of this specification, in which- Figure 1 is a longitudinal sectional view of my improved-pipe-Wrench, showing the samesecured to a pipe. Fig. 2 is a top plan view thereof. Fig. 3 is a cross-sectional View thereof ou the line @c x, Fig. 1. Fig. 4 is a perspective view of an end portion of the bar with the same inverted', showing the securing-spring for the 'fulcrum-block. Fig. 5 is a perspective View of the fulcrum-block,
Referring to the drawings, in which like numerals of reference indicate corresponding parts throughoutthe several views, 1 indicates a suitable metal bar, screw-threaded, as at 2, and is adapted to have the collar 3 mounted thereon. The collar 3 is adapted to slide upon the bar l by means of the adjusting-nut 4, which is interiorly screw-threaded and which operates upon the screw-threaded portion of the bar I. The collar 3 is formed with a pair of extensions, (only one shown,) as at 5, which areadapted to receive the securing-pin 6 for the metallic band 7 or other suitable material. This metallic band is of suitable length and is adapted to surround the pipe 8.
The under face of the bar 1 has an elongated slot 9 formed therein to receive a fasteningspring 10, which is suitably secured in said slot. The spring 10 is for the purpose of securing the lower end of the fulcrum-block I1 to the bar. The spring 10 has formed on its free end a shoulder or lug 12, which is adapted to catch into the aperture 14 of the fulcrumblock. The fulcrum-block 1 l is cut away,as at l5, to receive the en d of the bar l and is pivotally secured thereto by means of the pin 16. The free end of the metallic bandis secured between the end of the bar and the fulcrumblock, as shown at 17.
The adjusting-nut 4 is indented on its periphery, as at 18, to prevent the slipping of l It will be observed that when the spring 10 is forced upward it immediately releases the fulcrurn-blook, and as the same is pivotally secured to end of the bar l the metal band, which has been secured between the fulcrumblock and bar l, can be released therefrom.
It will be observed that various changes may be made in the details of construction without departing from the general spirit of my invention.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. I'n a pipe-wrench a screw-threaded metallic bar having a collar and adj usting-nut mounted thereon, an elongated metallic band secured at one end to said collar, a fulcrumblock pivotally secured to said bar and means IOO for securing the opposite end of said band to the opposite end'thereof between the said bar 1o saidbar,substantial1y as shown and described. and fulerumlbloek, substantially as shown 2. A pipe Wrench comprising, a serewl and described.
