Jariett, deceased, assignor to siid Apfel Application February 11, 1937, Serial No. lt5,342 3 Claims. (Cl. 294-11) This invention. relates to improvements in gripping devices and pertains particularly to an improved tongs for use in removing clinkers from furnaces, more particularly furnaces of the stoker type. . The primary object of the present invention s to provide an improved fbrm of clinker tongs having a novel type of gripping head by means of which it is possible to pick out clinkers which lo are disposed in the front part of the fire-box and which would ordinarily be difficult to reach with tongs of the usual straight type. Another object of the invention is to provide an improved tongs in which the means for effect@15 'mg the movement of a,shiftable jaw is so housed as to prevent it becoming damaged through violent contact 'with a fixed part of the furnace into which the tongs may be extended. The invention will be best understood from 20 a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity 25 with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims. 30 In the drawing: Mgure I is a view in plan of the tongs. Flg. 2 is a view in side elevation, a part being in longitudinal section. Referring now more particularly to the draw- 35 ing the numeral I indicates the shaft or body p6rtion of the tongs which is of tubular formation. At one end this tubular body is bent laterally, as indicated at 2, and terminates in the arcuate hand grip portion 3, the end of which 40 extends back across the center line of the main body of the shaft so that an opening 4 formed through the wall of the body at the convex side of the curved portion 2 will be directed toward the inner side of the handle adjacent the end 45 or rear, for a purpose to be hereinafter described. At its forward end the tubular body I is fixed within a collar 5 which forms an integral part of a cast bifurcated jaw which is indicated generally by the numeral 6. Each of the fureations 50 of this jaw is indicated by the numeral 7 and as shown this bifurcated portion extends obliquely from the part 5 so as to form a forwardly diverging angle with the axial center of the tubular body 1. The forward ends of the furcations or 55 jaws proper which are indicated by the numeral 7 are preferably silbstantiany parallel whereas their rear portions converge toward the collar 5 as shown in the plan view, and these straight forward end portions are slightly reversely curved to be directed back toward the axial cen- 5 ter of the body and their concave faces are transversely serrated to form t@e gripping teeth 8. Formed integral with the collar 5 are the spaced parallel ears 9 which project from the coller oppositely to the inner end portion of the lo bifurcated fixed gripping jaw 6. These ears are connected by a pivot pin I 0 and on this pin is supported the inner end of a single movable jaw finger I I which is of slightly- longitudinal arcuate form and arranged to have its concave 15 side in opposed relation with the concave sides or faces of the fureations 7. In addition this movable jaw i I is provided adjacent its forward end with teeth 12 upon its inner side for cooperative action with the teeth 8. At the attached end of the movable jaw II there is formed an inwardly extending actuating ear 13 which is disposed between the fixed ears 9 and which lies in the line of the center of the tubular body 1. This actuating ear 13 has ',2 attached to it one end of a pull rod 14 which passes through the body I I and out of the same through the opening 4 at the handle end. Pivotally attached to the handle 3 is a shiftable grip 15 to wliich the rear end of the rod 14 'O is pivotally attached. This grip i 5 is divided at its attached end to form the two spaced parallel arms 16 between which the body of the handle 3 positions and a pivot pin 17 passes through these arms and the handle body, as il- lustrated . From the foregoing it will be readily apparent that the handle 3 is in the form of a pistol grip so that the shaft or body I of the tongs may be extende d straight forwardly without the necessity 40 of uncomfortably twisting the wrist and by the use of the fingers engaging the grip 15 the rod 14 may be reciprocated to open or close the mov- able jaw I I relative to the fixed jaws 6. It wiII also b,- apparent that since the fixed jaws 6 are 45 upon the opposite side of the body I from the side from which the handle 3 is bowed, and since these fixed jaws extend obiiquely from the body 1, it ivill be comparatively easy to reach into a furnace fire-box, while standing back from the 50 open front thereof, and pick up clinkers which may be disposed adjacent the front wall of the body. Such an operation would be practically impossibl e with tongs in which the jaws project straight from the end of the body as it would then 55


2 be necessary for the operator 'to stand close to the open fire-box in order to dispose the shaft or body of the tongs at -the proper angle to bring -the jaws in clo:.ie to the front of the fire-box wall. Vvhat is claimed is: 1. A clinker -tongs comprising an elongated tubular body portion having near one end a bowed - portior@ merging into a straight terniin;?,l Portioii forniing a hand grip which exte-nds obliquely with jo- respect to said body, a finger -grip pivotally attached to the said bov,,ed portion of the body, a pull rod attached at o-,ie end i.-o the flilger grip and extending therefrom longitudinally through the tubular bctdy to prdtrude aut of the end re- 15 mote 'Lrom the finger grip, a fixed gripping ia-w attached to said rem6te end of the tubular body, a movable jaw pivotally attached to the said re.mote end of said tubular body, and a, pivoted coupling between the moveible- jaw aiid said 'pull 20 rod. 2. A clinker tongs comprising an elongated tubular body having one end bent to provide a straight term-'Anal portion and an intermediate laterally bow-p-d portion, the straight portion 25 form-,Ing a hand grip disposed obliquely of md exter@ding across the long axis of the body, t--Ilewall of the body having an aperti-@re formed therethrough which is directed towaxd the,inner side of the straight terminal portion, a finger grip @o pivotally attached at approx-imately the transverse center of the bowed portion to extend across the concave side of the same and between the aperture and said straight terminal portion, a pair -of spaced ears fixed to the other end of '@he 15 body, a fixe(-' jaw rr-ember projecting later-@,lly from said other end of the body, a r--- ovable j-aw havirig one end pivotaliy mounted b--tnveen said 2,125,214 ears for movement relat,ive to the fixed jaw, an actuating ear forming a part of the movable j'aw and disposed between said ears and in fron', of the--adjacent end of the tubular body, an-i a straight pull rod extending thru the tubu ar bo 5 and having one end--attached to said actuating ear and its other end extending thru the open- ing in the wall of the tubular body and attached to said finger grip. 3. Tongs of the character set forthi,corr@prising 10 a 'Uubular sliaft having a forward open end, said shaft being@-bent adjacent its other end to form an@@rcuate offset, sa:id arcuate offset merging -)Vlt'-q and terminating in a straight portion -on- stitutihg a hand grip which exterds obliquely 15 across the long axis of the shaft, the -shaft having an opening at the forward s4.lde of the arcuate off- set @:which is directed towa.rd the hand grip, a finger grip pivoted tb the sai,d offset and extend- ing irom the concave side between the hand grip 2(, and said opening, a collar encircling the forwatd end of the shaft, a jaw having a, substantially st raight part secured at 6ne end to and pre-ject- in f.-om the collar obliquely of the shaft and 9 beiiig sligh,.Ily longitudinally curved at its-free 25 other end, an elongated slightly lbngitudinaily arcuate jaw pivotally attac"@-ied at o@ie e,-Qd to the ebliar to be oscill,-@,ted relative to th,, first jaw, and a straight actuating rod passing throtigh the n le gth of 'he shaft and hw,7ing ore end extend- 3i-i ing through the forward end and pivotally attached to the pivoted jaw and its other I er-d extending throligh said opening and pivotal-iy attached to said finger grip. 3-5 JACOB P.
