2 Claims.
This invention relates to a tool for riveting, perforating and like operations and has for its objects the provision of an improved tool of this character which is very light and durable in construction and capable of exerting greater power and enable riveting, per-forating and like operations to be performed manually, easily and expeditiously.
In the accompanying drawing:
Fig. l is a side elevation of the tool in a closed or operative position and showing the tool organized for perforating material.
Fig. 2 is a top view of the same.
Fig. 3 is a fragmentary vertical longitudinal section, on an enlarged scale, of the front part of the tool in an open or inoperative position.
Fig. 4 is a transverse section, on an enlarged scale, taken on line 4-4, Fig. 1.
Fig. 5 is a fragmentary vertical section of the front part of the tool showing the Same organized for riveting purposes.
In the following description similar reference characters indicate like parts in the several figures of the drawing.
In its general organization this tool comprises a main supporting head or frame upon which are mounted die elements operating directly on the workpiece or material in hand, a pair of manually operated levers pivoted on the head, and power multiplying means which are actuated by said levers for moving lthe die elements one relatively to the other. v
In its preferred construction the supporting head or frame comprises outer and inner parallel arms or jaws I0, II which are spaced apart by a gap I2, a. neck I3 connecting the corresponding lower ends of said jaws, and pivot lugs III, I5 projecting longitudinally inward from the upper and lower ends of the inner jaw I I of the supporting head.
On the upper parts of the frame jaws are mounted the die implements which operate on the workpiece which implements may be of various forms in accordance with the specific function required, such as riveting, perforating, and the like.
In Figs. l, 2 and 3 these die implements are designed for perforating or punching holes in material and comprise a female die I6 arranged lengthwise of the tool and engaging the inner side of the upper part of the front jaw I0. This die is detachably mounted on this jaw by means of a pin I'I projecting outwardly from this die andengaging with a seat or opening I8 in the upper part of the jaw II). This die is provided with a central die opening I9 the front part of which has a cutting edge and the rear part of which extends laterally to discharge the slugs or punchings which are produced by cooperation with a punch or male die implement 2| which moves toward and from Ythe female die.
This punch implement is arranged on the front end of a plunger 22 which slides lengthwise in a guide opening 23 formed on the rear arm or jaw I I of thesupporting head between the lugs I4, I5. In rear of the jaw the plunger is provided with a forwardly facing shoulder 24 and between this shoulder and the rear side of the jaw II is arranged a helical spring 25 which surrounds the plunger and serves to yieldingly move the plunger rearwardly for opening or separating the die implements.
The numerals 26, 2'I represent upper and lower operating levers which are pivotally connected with their front ends, respectively, to the rear ends of the head lugs I4, I5 by means of pins 28, 29 so that these levers may be turned inwardly into a position in which the same are parallel, as shown in Fig. 1, or outwardly in which the same diverge rearwardly relatively to the supporting head. This movement of these levers is transmitted to the plunger for moving the same forwardly into a closed or operative position by intermediate operating means which cause the power applied to the levers to be multiplied.
These operating means may embody this invention in various forms, but the form shown in the drawing is constructed as follows:
The numeral 3i] represents an intermediate lever having an upper bifurcated or forked end straddling the upper head lug I4 and pivoted thereto by a pin 3|. Between its upper and lower ends and below the upper lug I4 the intermediate lever is provided with a bearing nose 32 which engages with the rear end of the plunger. At itsV lower end and immediately above the lower pivot lug I5 the intermediate lever is provided with an anti-friction thrust roller 33 which is pivoted thereto by a pin 34.
The numeral 36 represents a cam arm projecting inwardly from the front end of the upper operating lever 26 and provided on the front side of its inner end with a cam face 35 which engages with the rear side of the thrust roller 33. Adjacent to its inner end the cam arm is connected by a pin 3l with the front end of a double toggle link 38 which latter has its rear end connected with the inner side of the lower operating lever by a pin 39.
Preparatory to using this tool the two operating levers are spread apart whereby the cam arm 3S and the link 38 are unfolded relative to each other and the cam arm is withdrawn rearwardly, thereby permitting the spring 25 to move the plunger and intermediate lever 30 rearwardly and separating the die and punch members I6 and 2|, as shown in Fig. 3. After placing the workpiece to be perforated between the punch 2i and dief lvthe two operating levers are moved toward one another and during this movement the cam arm 36 not only exerts a leverage against the thrust roller 33 but also a cam action. At the same time a toggle elect :isA produced by the folding action of the toggle ylink.38:. and the cam arm 30 which further increases the.
forward pressure against the thrust roller. Ow-
ing to the load on the intermediate. leverbeing located between its fulcrum and the power applied thereto and also close to this fulcrum, the
maximumA purchase` of uthis lever: is obtained.-
Thecombinedreiect of .thesezactionsroperates togreatly multiply the power which is :applied to theY operatingflevers so: that the/,plunger `is moved forward with ahighpressuregby; comparatively low hand pressure against the operating levers, thereby .enabling comparatively, heavy work l,to be done easily, conveniently, and quickly. .y
Instead ofiemploying av female die.: and punch as the working implementsfof ,the .'too1,. other mplements .may be .usedzinaccordance with*v the face 12.50Y thatupon placing-,a ,rivet betweenV the anvil and ltheplungenthe rivetwill: beupset and;
connect the parts through which it passes upon closing the operating levers.
I claim as my invention:
1. A tool of the type disclosed, comprising a supporting head, a plunger slidable on said head, said plunger and head being provided with working implements adapted to operate on a workpiece, and means for actuating said plunger including any intermediate lever pivotedv at ione end on saidhead'and providdat'itsopp'osite end with a thrust roller and having a nose between its ends which engages with said plunger, two main operating levers which are pivoted on said headand one of which has an arm engaging with said roller, and a toggle link connecting said arm andthe other main operating lever.
2.A;.too1 ofthe type disclosed, comprising a headhaving front and rear jaws which are spaced 'apart but connect at corresponding ends and? upper and -lower pivot lugs =projecting..rear wardly from the upper. and glowerpartsof VVsaid rear jaw, a longitudinally movableplunger guided on said rear jaw between said-lugs, saidJ plunger and front jaw beingprovided: with lcooperating working .implements adapted' to oper` ate on a workpiece, and means-for actuating saidplunger including an intermediate lverpivoted at one end on one ofv said. lugs andhaving its opposite end adjacent tocthev oth'enlugand engaging between its'ends withvsaidplunger, two
main operating levers which. are pivotedV on :the
rear ends of saidlugs and. one-pf which is -provided with an arm projecting toward the other lug and engaging apart .roflsaid intermediate.
