TONG.
Application fi1ed November 14:, 1923. Serial No. 674,654.
This invention relates to new and useful improvements in a tong.
One object of the invention is to provide a tong of the character described, specially constructed for use in handling casing, pipes, and the like in carrying on drilling operations; however, the implement is capable of general use.
Another object of the invention is to provide atong which may be readily applied to the work by one man, whereas tongs of this general character now in common use require two men to apply and secure them to the pipe, or casing, to be turned. Tongs of this character are usually very heavy, and for that reason are suspended by cables or chains, in the derrick and in applying them to the pipe, or casing, they are swung into the proper relation to the pipe by one man and are engaged around the pipe by another. The improved type of tong herein described requires but one man to manipulate into working engagement with the object to be turned. I
A further feature of the invention resides in the provision of a tong which is of very simple construction, which can be cheaply and easily manufactured, and is very eifective in use.
lVith the above and other objects in view the invention has particular relation to certain novel features of construction, operation and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Fig. 1 shows a partly in section.
F 2 shows a side view thereof,
T lg. 3 shows an inside view of one of the jaws, and y F lshows a cross-sectional view thereof.
Referring now more particularly to the drawings, wherein like numerals of reference designate similar parts in each of the figures, the numeral 1 designates the tong handle, one end of which has a transverse slot 2, therethrough, and beyond said slot the operative end of the handle has a convex bearing face, 8. This face is toothed and may be integral with the handle if desired. As shown, however, there is a detachable jaw 4 which is dovetailed into said end of the handle.
plan view of the tong The numeral 5 designates a pipe engagthrough aligned bearingsin the handle and,
extension 6. The hook 5 has the inside toothed jaws 8, 8, which are dovetailed therein. The jaws at and 8 are held against becoming loose, and dropping out by means of the respective set screws 9, and 10, 10, which are threaded through the handle, and the hook, respectively, and whose inner ends project into lengthwise grooves 11, and 12, 12, respectively, in said jaws.
The free end of the extension 6 has a suitable hand grip 13 screwed therein for convenience in handling the tong.
In use, the tong is suspended by means of suitablechains, or cables as 14:. These are usually attached to eye bolts 15 which are fastened to the handle and hook, respectively, as shown.
In operation, the operator stands on the side of the tong opposite the hook and when it is desired to apply the tong, it is swung into proper relation to the pipe, and the grip 13 is then grasped and the hook 5 manipulated into engagement around the pipe.
What I claim is:
In a tong, a handle having a slot therethrough, a substantially arcuate member passing through said slot and pivoted to said handle and projecting therebeyond, a a removable toothed jaw carried by said handle the working face thereof being convex, a plurality of toothed jaws carried by said arcuate member, said jaws opposite each other and adapted to cooperate, said jaws being dovetailed into their respective carrying members and having an oblong groove in their inner sides forming bearings, set-screws threaded through the corresponding jaw-carrying members and whose inner ends project into said bearings, and a grip carried by the arcuate member for manipulating the same.
In testimony whereof. I have name to this specification.
THOMAS W. OOATES.
