BURNING COLLAR.

Application led January 23, 1,928. Serial No.k 248,911.r

This invention relates to improvements in electrical battery working tools, having for anobject to provide a burning collar device for use in burning or fusing electric storage battery connectors to the pillar posts thereof whereby to insure a positive and efficient mechanical and electrical connection therebetween, the device being of such construction that with placement or engagement of the same over or about that portion of aconnector engaged over a pillar post, a hot or fusing flame may be directed thereupon from a torch or other device, causing the even and unifom transmission of heat to the connector and post at a temperature suflicient to effect a fusion of the metals from which they are formed and hence, with cooling, produce a positive mechanical and electrical connection after which the burning collar may be v freely removed, leaving a finished and nicely appearing job.

The invention also aims to provide a device of the character described formed of a material whose melting point is above that of the connectors or posts to be burned thereby, said device, with arrangement about a connector engaged over a pillar post, serving the dual agency of a shape retaining mold for the connector and the post during that period when a fusing flame is applied to said elements, thereby preventing malshaping of the heat treated portions of the post and the connector and thus, with completion of a burning operation and removal of the deviceansuring a finished and properly appearm0r o afher objects of the'invention willbe in part obvious and in part pointed out hereinafter. Y 'c In order that the invention and its mode of operation may be readily understood by those skilled in the art to which'it apperta-ins, I have in the accompanying illustrative drawings set out one possible embodiment of my invention. Y

In these drawings: l

Figure 1 is a side elevation of the improved device applied over a battery terminal and filler during a burning operation, j,

Figure 2 is a top plan view thereof, and

Figure 3 is a vertical transverse section through the same.

vHaving more yparticular referencev to the drawings, in connection with which like characters of reference willdesignate corresponding parts throughout, the improved burning collar consists of a substantially .U-shaped piece of metal whose fusing or melting point is materially above that of the metal from which the connectors and pillar posts in connection with which it is to be used are formed, constituting a collar designated for convenience by the numeral l. |The inner and outer side portions of thefcollar l are arranged in relative parallelism buttaper upwardly as is shown in theFigure 3, whereas the inner side of said collar is formed with a cross sectionally semi-circular seat Q corresponding or approximately corresponding in size and shape to the standard design and size of battery cell connectors, so that the device may be freely downwardly engaged over a battery connector subsequently to the engagement of the same over a pillar post; the

free extremities of the collar being thickened as isindicated by the numeral 3, thus reducmg the 'open side of the semi-circular seat 2 so as yto permit the device to generally conform to the contour or shaping of a connector engaged thereby.

For convenience in handling or properly adjusting the burning collar with respect to a connectorand a pillar post engaged thereby` I may and preferably do provide the same with a handle such as is indicated herein by the numeral 4, forming said handlefof `a length of suitable material, one end of which is engaged and anchored in a boss or lug 5 cast integral with the outer side and intermediate portion ofy vthe A collar l, the said handle being disposed upwardly with respect to the collar and formed with -a coiled hand grip portion 6 whereby it may be engaged and held by a user without liability of burning-him as'by transmission of heat from the collar during a burning operation to the handle.

In using .the improved burning collar, a connector such as is shown herein and indicated by the reference character Gis engaged over a pillar post P to which the former is to be fusedl and with such engagement, the burningm'collar is dropped over that portion of the connector C engaged about or receiving the pillar post P therein. At this time,'a hot llame is directed downwardly from f a torch or other suitable device onto the connector and the adjacent port-ions of the pillar post, hence, melting a portion of the metal of each thereof and causing a fusion of such molten metals. Following this melting of parts of the connector and the pillar post,

ll() i the flame is removed and the device is permitted to remain about the connector until the same, together with the pillar post have fully cooled whereupon the burning collar may be then drawn upwardly and away from the connector, leaving a finished and, nicely appearing job.

By reason of the shapingv of the burning collar it will be understood that the same will serve in the capacity of a shape retaining mold for the connector engaged about a pillar post to be mechanically and electrically interconnected and because of this, the malshaping of the connector during a burning operation will be positively prevented and at the same time, an efficient mechanical and electrical connection will be produced between the two battery elements. Also, by reason of the tapered formation of the burning collar l, it will be understood that the same will automatically adjust itself to snug engagement over and about a connector to be burned thereby, such slight variances in size or design of the connector being compensated for by the tapering of the inner sides of the collar. Likewise, this upwardly tapering formation of the collar l will permit of its free removal from a connector subsequently to a burning operation in `that with imparting of an upward pull to the burning collar from the handle 4, the enlarged lower portion of the collar will readily and freely disengage itself from the connector and move upwardlythereover.

From the foregoing, it will be understood that I have provided a simple and high elficient type of battery working tool whereby an effectual mechanical ,and electrical connection may be effected between the connectors and pillar posts of an electrical storage battery, the device serving as a means for positively preventing the mal-shaping of the melted or fused portions of either the connector or the pillar post and in `so doing, permitting the production of a mechanically sufficient and nicely appearing job by comparatively unskilled labor, an item of material importance to battery manufacturers who, have heretofore been compelled to rely upon the burning of battery connectors to pillar posts by skilled and highly salaried labor. Furthermore, it will be understood that by reason of the inside surface or shaping of the shaping of the burning collar, the device may be successfully used in connection with the burning of any type of connector now prevalent in 'this particular art, the inside taper of the collar permitting of ample compensation for variance in cross sectional size or shaping of the connector and at the same time, permitting the collar to be snugly engaged about said connector prior to a burning operation. Herein, it should be noted and understood that whereas the outside sha-ping or formation of the collar may vary within a wide range, the inside shaping or surfacing of the same will generally correspond to that shown in the accompanying drawings whereby the fundamentals of the device may be etl'ectually served, that is, that the collar may be cngaged over battery connectors of dilferent size or of different shape, according to the products of different manufacturing con* cerns. Y

Manifestly, the construction shown is capable of considerable modification and such modifications as are within the scope of my claims, I consider within the spirit of my invention. i

I claim:
