BATTERYLJAR-FORMING MACHINE.

Application "'leclDeceniber 24;` 1.921.

To all 'whom t may concern:

Be it linown that? I, Jarras `H: WAGEN"q Hons/r, a` citizen otithe Unitedf Statesy re siding` at Jackson,l inthe county otl Jack-` son and Stateot Michigan,` have invented a` certaininew and useiul Improvement in BatteryJanForming" Machines,` ot which the following isa full,` clear, and exact de scription, reference being had to thej accom# panyingdrawings.`

This invention relates generally to that tery jar forming machines Sand more particularly to `certain `improveinents upon the battery jar formingA machine patent to me In that* ma izontal position upon' the stoel: and "then the stockfolded around the mandrel Atodorn'r the'jar. In the presentinvention the man` drel issupported in a substantially vertical position and likewise `the stock and the stock is' tol-ded' aroundthe mandrel `while held in such vertical position,` thereby rendering theoperation oi the device much l easier thananyot the battery formingma Another object chines `heretofore devised.` of4 the. invention is tov providej a mandrel capable ot producing af multiple cell battery jar having the platel supporting lugs. in the bottoni thereof.` Another object of the" inventionA is to4 provide a battery jar having` rounded coriiei's `in .contradistinction from one havingsquare corners. A turther object'of l the invention is to provide a'de-` vice inwhich.thevarious operations cairbc' accomplished either by hydraulic or pneumatic pressure anda still further object .is to providea machine which cairbeusedin connectioiilwith the liquid `torni ot `mandrel capablef ot producingA a multiple" cell j ar or a mandrel composed of hinged sections such as` disclosed in my application tiled October 31,' 1921,\S'erial No. 511,859.` Other objects will .bccomeapparent as 'the description proceeds.

Theinvention consists in the novel tea-` tuiesof construction and combinatiom allot" which will be fully described hereinafter and pointed out in the appended claims.

In the drawings forming apart `o'fthis` specification Fig. 1 is a vertical sectional view ot a battery `jar torniing 'machine 'em-V bodying my invention, the `hinged plates being. represented as closed aboutthe` mandrelyFigiQJis al `vertical sectional view'oi'i the line 2-*2 ot Fig. 1,1the hinged plates Serial No. 524,647'.

A In the practicalembodiments ot my invention l employ amain trame 10 which is substantially upright" and' provided with'` a back 10a which is slightly inclined and also a base portion 10b which isiarranged at right angles to the bacll()n and consequently is" slightly inclined also. The main Lframe also comprises a mandrel support-10c on which the mandrel is supported just before being placed into oiremoved froiirthe' machine.

Attached to the `bacl f10a is aback-plate- 11A and` connected to this b'acltfy plate lllbrv suitable` hinges is` the side plate 12 landaise the side plate 18, wliicli"is also connected by suitableliiinges,` and a front `platelslfisl connected to' the side plate 12A and'a front plate 15 is hinged tothe side plate `13. The

back plate 11 and the plates 12,13, 14 and 15 are provide-d with a supporting ledge' or rib 16 adjacent to the lower ends thereindicates a mandrel support-rigidlybolted` to thefbase 10b in such position that when the plates 12, 13, 1taiid'15 are opened out as shown in Fig; Qand the stock` placed thereon, the mandrel having the4 partition stiiipsarranged therein can be slid 'from the intatta mandrels rest C onto the mandrel support 18 and when in its final fixed position will contact with the stock and press the same against the back plate 11 and then the plates 12, 13, 111 and 15 can be folded about the mandrel so that the stock willbe progressively folded about the sides and ends of said mandrel and force out all of the air, thereby preventing the formation of air pockets. The mandrel, besides having the spaces 17C to receive the partition stock is formed with the recesses 17d into which the material for the lugs is placed and then before the mandrel is positioned upon the. support 18 the piece of rubber stock which is to form the bottom of the battery jar is placed upon the upper end of the mandrel as thus supported. The mandrel support is provided with a clip 18 at the back of the support and clips 18 at the sides thereof, which clips 18b are connected to a bar 18C which is arranged in a recessed portion of the support 18 and is connected to any suitable form of fluid operated piston by means of which the bar 18c is moved up and down in order to bring the clips 18 into or out of engagement with the base of the mandrel. The plates 14 and 15 are provided with off-center tension springs attached to suitable pins mounted on the upper ends of the plates for holding these plates under pressure in either their opened out or their closed positions, their ope-ning movement being limited by the abutting of their rear edge faces against t-he adjacent edge faces of the plates 12, and 13, respectively.

The two plates 14C and 15 act as folders for the two ends of the margins of the side forming sheet of stock and they also form the side seam as illustrated most clearly in Fig. 9. On these plates I provide a pair of coacting longitudinal blades lll.a and 15a, respectively, for forming the seams, said blades having a shearing action to trim ott the excess from the overlapping edge of the niaterial.

The upper ends of the plates 11 and 12, 13, 14 and 15 are provided with shallow inwardly projecting flanges 11b, 12b, 13b, l-lb and b having concave forming faces for the purpose of turning the edges of the side forn'iing sheet around those of the bottom forming sheet to make the bottom edge seams. For clamping the folded plates together in closed position upon the work, l provide a hand lever 19 hung on a pivot between the arms of a fork 2O and having a hub cam 21 cooperating with a complemental locking member 22 arranged and operating in substantially the same manner as similar parts in my patent previously referred to. As previously stated a piece of stock is placed u'pon the upper end of the mandrel for the purpose of providing a bottom to the battery jar; and for the purpose of binding said piece of stock to the mandrel while the jar is being formed I employ a head or plunger carried at the lower end of a rod 31 which works up and down in bearings 10d constituting a part of the frame and actuated preferably by the fluid operated piston 32 through the medium of links 33 and bail 34, said links and bail constituting a toggle. The up and down movements of the rod 31 are limited by means of a stop 35 adjustably mounted upon the rod and adapted to contact with the bearing portions of the frame. On the edges of the plunger are mounted four downwardly projecting plates 36 for compressing the inwardly turned edges of the side forming sheet which overlap the margins of the bottom forming sheet to constitute the bottom seams, these plates sliding on the edge-turning flanges 12a, 12b, etc. The ends of the plunger plates as well as the ends of the edge-turnng fianges carried by the side plates meet so as to form complete quadrangles.

In Figs. 5 and 6 I have shown slightly modified forms of plates 11C, 12C, 13c and 14, doing away with the plate 15 and it will be noted that each plate is formed with an upwardly curved edge 40 so that when the four plates are folded together as shown in Fig. 5, the stock folded about the mandrel will be given rounded corners as most clearly shown in Fig. 5 and any suitable form of locking mechanism may be employed for binding the parts together.

The work-table can be arranged in advance of the main frame and upon which the mandrels can be placed preparatory to being arranged upon the mandrel rest l()e just before being introduced into the machine or from which the mandrels with the jar thereon can be placed after said jar has been formed and removed with the mandrel from the machine. By arranging the mandrel and the folding parts in substantially a vertical position, it will be much easier to manipulate the machine inasmuch as the mandrel can be quickly and easily pushed from the rest 10c onto the support 18 and the stock can be easily arranged upon the opened out plates upon the ledge 16 and then as soon as the mandrel with the partition strips arranged therein is placed upon the mandrel support, the hinged plates can be folded around the mandrel, carrying with it the stock to form the sides and the bottom forming piece with the lugs having been previously arranged upon the top of the mandrel, the plunger can be lowered and the seam forming operations completed.

By arranging the mandrel and the enveloping plates or wings in a substantially vertical position, l overcome the objectionable features of the machine disclosed in mypatentpreviously referred,` to.` In that stock rat that point,A and :ing order to overcome this, a thin` piece ofmaterial had-toloe1 inserted between the stock andthelhoty plate beneath the; mandrel.

to counterbalance: these side-Wings thereby providing avvelghty.` and` cumbersome piece otnmechanism. All otstfhese objectionable features` are uavoided byarranging .the `mandrel and the enveloping plates. or; Wings: in` a. substantially vertical position and*l the operatiorrxotfthe machinev` is.rendered` much easierJ in every respect and 'by having 1 the slidabley mandrel in; combination with asuit.-` able support providedfl with clamps,A the mandrel [isffquickly andeasily.positiened.` accurately with reference tothe toldablermem bers.`

While I have shown a hand operated;

meansyforo ning and'closingf the plates it is obvious t at fluid operated means may be employed if so desired.

It Will thus be seen that I provide a simple and highlv eiiicient battery jar forming machine capable of carrying out all of the objects hereinbefore referred to.
