CRlNlPlNG-TONGS.
SPECIFICATION forming part of. Letters Patent No. 273,382, dated` March 6, 1883.
Application ledNovember 15, 1882. (No model.)
To all whom it may concern Be it known that I, FRANK R. PACKHAM, a citizen .ot the United States, residing at Mechanicsburg, in the county o'f Champaign and State ot' Ohio, have invented a certain new and useful Improvement in Crimping-Tongs, of which the following is av full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part ot' this specification.
My invention relates to a device for crimpy ing sheet metal.
The object of my invention is to provide a crimping device in the nature ot' a pair of tongs particularly adapted to crimping the ends of sections orjoints ot' sheet-metal pipe for the purpose of tapering the same, so that the di'erent sections so crimped may be readily joined together in the ordinary manner.
My invention consists of a pair ofjaws, each provided withV a series of serrations or lutes of equal depth throughout their length, in combination with a pin which pivots said jaws together, and which is so placed in relation to said jaws that when closed together the serrationsinthe differentjaws willbecompletely engaged at one end and he gradually separated toward the other end, whereby crimps or flutes of a depth gradually decreasing to a featheredge may be produced.
My invention further consists in providing crimping-tongs with detachable jaws, the working-faces of which are provided with serrations Aot' a different character from those in the permanent jaws, the other or outer faces of said detachable jaws being formed to lit the serrations ofthe permanentjaws, whereby the sameY tongs may be adapted to perform ditterent kinds ot' work.
My invention further consists in certain constructions and combinations of parts, as hereinafter more fully described and claimed.
In the accompanying drawings, which form a part of this specification, Figure l is a view illustrating the manner of using my improved crimping-tongs. Fig. 2 is a side elevation View of the tongs, showing the detachable jaws inserted for use. Fig. 3 is a partial sectional elevation, showing the tongs arranged for use without the detachable jaws. Fig. 4 is a perspective view ofthe detachable jaws removed,
a feather-ed ge.
vand Fig. 5 is a sectional view taken on the line x in Fig. 2.
Like parts are indicated by similar letters of reference in the different views.
In the said drawings, a and b represent respectively the handles of the tongs, which are pivoted together by a pin, p.
c and Z are the permanent jaws, each ot' which is made in a single piece with one of the handles a b, and each provided with a series of serrations or flutes, e e, of an equal depth throughout their length. Y
c d are the detachablejaws, provided on their outer faces with serrations c' c', which correspond with the serrations e cot' permanent jaws b c, and provided on their inner or working faces with diagonal serrationsj'f. These serrations f f are of a graduallydecreasing depth from heel to point ot'jaw.
rlhe handles a and b are each provided with two holes, g and h, vfor the pin 19.
VWhen it is desired to used the tongs without the detachable jaws the piu 19 is inserted through the holes h h, which are so placed in are closed the jaws are brought into the relative position shown in Fig. S-that is, at an angle with each other-so that while the serrations Completely enga-ge at the heel of the jaws they separate gradually toward the point.
To crimp a piece ot' metal or the end of a pipe, the metal is inserted between the jaws, which are then closed together by means ot' the handles a b. The serrations in the respective jaws coming entirely together at the heel of thejaws, the crimps produced in the metal will be at this lpoint of a depth corresponding tothe depth ofthe serrations in the jaws; but by reason of the relative position ot' the jawsabove stated the said crimps in the metal will gradually decrease in depth up to Orimps or ilutes when thus formed in the metal ot' a pipe at its end produce a perfect taper in the pipe at the end so crimped.
When it is desired to use the detachable jaws the pin p is put through the holes g g. rEhe detachable jaws are then inserted in the permanent jaws, with their straight serrations e e' fitting in those, e e, in saidpermanent jaws. The detachable jaws are then secured IOO in this position by a small screw, s, or in any other suitable manner. Thetongs lnay be now used for producing diagonal crimps, and the scrrations beingof gradually-decreasin g depth a taper may be produced, as before. In ordinary work the straight scrrations in the 'permanent jaws will be used; but in crimping stove-pipe ot' an inferior quality the diagonal serrations are preferable, as by their use the crimps are produced in vthe metal across the grain. The metal, when thus crimped, will not be apt to split, as is sometimes the case when the crimps are made in the metal parallel with the grain.
I make tbe jaws in cross-section on the arc of a circle, as shown in Fig. 5, when intended exclusively for crimping pipe, so that the circular form of the pipe will be retained. This is particularly desirable when the tongs are to be used for crimping small pipe.
It is evident that the relative position of the straight and diagonal scrrations may be reversed and the same result be obtained-that is, the diagonal serrations may be placed in the permanent jaws and the straightserrations in the detachable jaws.
lf desired, the jaws c d may be placed at an angle to the handles a b without departing from the spirit ot' my invention; and, indeed,
this may be found advantageous in some kindsof work.
Having described my invention, I claim as new and original- 1. The combination, with the jaws c and d, each provided with a series ot' scrrations ot' equal depth throughout their length, ot' a pin, p, pivoting said jaws together, said pin being so placed in relation to said jaws that when closed together the scrrations in the different jaws, while being completely engaged at one end, will be gradually separated toward the other end,substantially as an'd for the purpose set forth.
2. The combination, in a pair of crimpingtongs, of a pair of permanent pivoted jaws with a pair of detachable jaws,said permanent jaws each provided with a series of serrations, the scrrations of one jaw being adapted to fit those of the other jaw, and said detachable jaws each serrated on one face to correspond with the scrrations in one of the permanent jaws, and each provided on the other or working face with serrations of a ditferentcharacter from the scrrations in the permanent jaws.
3. The combination of the pivoted jaws c c1, each provided with a series ot` scrrations, the scrrations inthe different jaws being adapted to fit each other, said jaws being formed in cross-section on the arc ot' a circle and relatively adapted to produce crimps of a graduallydecreasng depth,substantia1ly as and for the purpose set forth.
4. In a pair of crimping-tongs, the combination, with a pair ot' permanent jaws, ot' detachable jaws adapted to be inserted in the permanent jaws, one pair of said jaws being provided with a series of straight scrrations -and the other pair provided with diagonal serrations, substantially as and for the purpose set forth.
5. The combination, with the handles ab, each provided with holes g It, and permanent jaws c d, having scrrations e e, of detachable jaws c d', having scrrations jfot' a different character from those, e e, in the permanent jaws, substantially as shown and described.
6. 'lhe combination, with the pivoted jaws a b, formed in cross-section on an are of a circle, and provided with scrrations e e ot' equal depth throughout their length, of a pin, p, so placed that when closed together said jaws will form an angle with each other, substantially as shown and described,and for the purpose set forth.
In witness whereof I hereunto subscribe my name this 27th day of October, A. D. 1882.
FRANK R. PAOKHAM.
