' ed tools ci that type in which i' D having a threaded engagement with said Y on JU @L 93339473. Speeincation ci ppieation o @Elev/tom it may comemf Be it known that we, KUHN ano LAWRENCE H. THOMAS, both citizens ofi the 'United States of America, end Spiess, a citizen of the Republic oi? iiance, having taken out first citizenship papers the United States of America, ail residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and` useful Improvements in Electri cally-Heated Tools, of which the following; is a speeicaton, reference being had 'theme in to the accompanying drawings,
The invention relates to electrica i:
he heated is dtachably connected to heating unit so as to permit ci removaio is the object of the invention te construction in which the heat gaie will pass by conduction into the toni e 'n cient quantity and at the same time evciding the over-heating of the generating this end the invention consists in 'the stiuction as hereinafter set forth in the drawings: A
Fi ure l is a longitudinal section through an e ectrically heated Soldering1 icon9 evohodying our invention;
Fig. 2 isa cross-section thereof.
A is the tool to be heated, which is gocevided with an enlarged shank E in a -Hat face. C is a cyiindrical onsino fior inciosing the heating unit conpied to the shank of the tool. hy
shank, as indicated at Heietofox'e, constructions ci 'this typo have been formed with the heating enit ciarnped between cylindrical Segmente extending lon 'tudinally within the casing 'Ca the ends olsaid segments hein-g in heat conducting contact with the shank oi the The area of the heating unit 'is restricted to the area of the longitudinal secL1 tion of said cylinder segments and with this, if the heat generation is iarge. there is danger of attainm a temperature too high to be desirable. e have therefore devised a construction where in place of the area of a single longitudinal section, double this .area is attained for the heating imitand ali the heat enerated will be conducted into a heat-distributing body in direct Contact with the shank of the tool. As shown, F is a ciamped thereto hy segmental pi'essin'e plates H on opposite sides tnei'eoa The 'two sections oi the heating unit are compie-te in themseives and the eiectric current Apassing therethiough does not 'through 'the wedge theiehetweev.. enter end is eniarge presents area corresponding to the end of the sha lil, against Whici. ahnte The nressnie ii are heid contact wil Ae wedge, iiist hy then1 the seco hy weaning action oi the core. by a shonideied engagement if' between the presente tes H and the cas- C? wher 'thveaded portion E is sci'ewed on t .c B7 iviii move aid ovessurempiates 'longitndinaiiyi- @oneqnei y, said piessnie lplates wiil nionnt 'fhe wedge-shaped cone .fd iiii'niy pressing the n ts contact theiewith and then transfnit longit dinai movement to the o the head` thereof, pressing the iatoei the shanh B.
To avoid 'oss cn outward through f ie i iiioin 'the caeoniy nari'ow "ainsi the hensiii@ .'iscnstrengtiiened oy -fith une c desciihed, n the sleeve E n, sci e9 the shank B viii he infini t conclue iig contact with the head i and the'wenne shaped cove F wili in goed heat-condo g contact with 'the sections cie unita the unit is then connected into an ele tiic circuit, the eat generated Wiii he conducted inward into tine wedge-shaped ineinhei1 i? and then longitn dinally to the head i9 hom which it willi pass into the shank B end then to the toni.
What we claim as enr invention is:
i. The combination with a tooi to he heated, of a separate body extending rearward from said toni9 the adjacent ends of said tool and body havin correspondin surfaces in contact eac other and sai iongit body having e surface extending in a' plane The cose F at an oblique angle to its longitudinal axis, a clamping member having a surface parallel to said obliquely inclined surface for a wedging engagement therewith, a heating unit clamped by the wedgin engagement of said clamping member and ody member, and means connecting said clamping member and tool for effecting a relative longitudinal movement thereof to simultaneously wedge said unit and to press the contacting surfaces of said tool and body together.
2. The combinationwith a tool to be' heated, of a heat-conducting body extending rearward from said tool, the adjacent ends of said tool and body being parallel and in contact with each other and said b ody having a surface in a plane at an obllguc angle to its longitudinal axis, a coperat1ng member having a parallel oblique surface and forming in connection with said body a clamp, an electrical heating unlt secured by said clamp, and means for moving said cooperating member axially of said body relative to said tool to simultaneously clamp the unit and clamp said parallel contacting surfaces of the body and tool.
3. The combination with a tool to be heated, of a member movable longitudinally with respect to said tool provided with an obliquely inclined or wedging surface, a heatconductin'g body intermediate said longitudinally movable member and toollhaving a coperating oblique or wedge surface and also provided with a transverse surface paralle] andy in contact with a corresponding surface on the tool,Y a heating element arranged between the wedge surfaces of said movable member and body, and means for adjusting said movable body relative to said tool to simultaneously clamp the element be tween said Wedge surfaces and to clamp said transverse surfaces of the tool and body in heat-conducting contact.
4. The comblnation with a tool having a transverse inner end surface, of a heat-conducting body having a corresponding surface in contact with the surface of said tool, said body having a rearwardly extending wedge-shaped portion, a coperating wedge member, a heating unit arranged intermediate said wedge members, and adjustable means connecting said coperating Wedge member and tool for relatively moving the same to simultaneously clamp said element and said body in heat conducting contact with said tool.
5. Thecombination with a tool tobe heated.
ing wedge-shaped portion, a coperating wedge member of segmental cross-section,a tube surrounding said heat-Conducting body and coperating member having a shouldered engagement with the latter to move the same longitudinally, and a peripheral engagement for preventing lateral displacement, said tube having a threaded engagement with said tool, and a heating element between said body and coperating wedge member clamped by the screwing of said tube toward said tool, said adjustment also clamping the parallel surfaces of said body and tool in contact.
6. The combination with a tool to be heated having a transverse rear surface, of a heat-conducting body having a surface parallel to and substantially co-extensive with said transverse surface, said body being also provided with a rearwardly extending centrally arranged wedge-shaped portion, coperating wedge members on opposite sides of said wedge-shaped portion and complementary thereto to form a cross-section substantially co-extensive with that of the tool, a pair of heating elements clamped between said cooperating members and the opposite faces of said wedge-shaped portion, and a tube surrounding said cooperating members having a peripheral and end thrust engagement therewith and a threaded engagement with said tool, whereby the screwing of said tube 'upon said tool will simultaneously clamp said heating elements and the contacting surfaces of said tool and body.
7. The combination with a tool to be heated, of a body extending rearward therefrom, said tool and Abody having corresponding parallel transverse contacting surfaces and said body being provided with a rearwardly centrally extending wedge-shaped portion, coperating wedge members upon opposite sides of said central wedge shaped portion,
vsaid members being complementary segments of a circular cross-section and cut away to provide a peripheral bearing of limited area, heating elements between the opposite surfaces of said central wedge and said cooperating wedge-shaped members, and a tube surrounding said cooperating members forming peripheral and end thrust contact therewith, said tube having a threaded portion for engaging said tool to provide for simultaneously clamping said heating units and the contacting surfaces of said body and tool.
In testimony whereof we aiiix our signatures.
