FRICTION-ARBOR.

Specification of Letters Patent.

ratented June 5, 1906.

1'0 It whom, it 'ITl/Cl/Z/ concern:

Be it known that I, PHILIP P. NUNGESSER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Friction-Arbors and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. I

My invention relates to friction-arbors constructed and adapted to mechanically apply insulating-linings in dry-b attery cans, all substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a front elevation of' an arbor embodying my invention and of the drive mechanism for the same. Fig. 2 is an end elevation of the drive mechanism for the arbor looking inward from the right of Fig. 1. Fig. 3 is an end elevation of the arbor with the lining tightly wound thereon preparatory to entering the same into a can. Fig. 4 is an end view of the arbor and can and the lining unwound in the can as it is being pressed against the walls thereof by the arbor under the manipulation of the operator.

In the preparation of dry batteries of the kind now universally in use it is necessary to line the inside of the zinc or equivalent can or jar with a layer of absorbent insulatin material, and the said lining should be mly and uniformly pressed against the inner wall of the can from end to end. This work has heretofore been done exclusively by hand, and handwork is still employed in large factories in the absence of knowledge of any other more successful or expeditious wa of doing the work; but handwork is at its est slow and expensive and lacks utterly in uniformity in workmanship, as well as resulting in a large percentage of bad work owing to carelessness or other personal defect in individual workers.

My invention is a complete substitute for hand labor in this operation, except as to the placing of the lining upon the arbor and from which it is unwound mechanically into the can, all as will now clearly appear.

Thus A represents the arbor as a whole,

which comprises a rod or shaft 2, upon which four several pulleys for driving the arbor are mounted, and the said arbor is provided with a frictional body or outer engaging portion or surface 3, of rubber or of any other suitable or equivalent material, which will exert a frictional or adhesive sort of effect upon the lining for the can and engage the same in such manner as to hold the lining wrapped thereon until it is released into the can itself.

As shown herein, I use simply a suitable rubber tube or sleeve 3, secured on the shaft 2 by a nut 4 and abutting against a substantially disk-shaped collar 5 at the base of the arbor. This collar or plate has a plain flat face, so as to form a square surface to bear against the inner edges of thelining and of the can as they are brought together, and the collar 5 rotates with the arbor-shaft. Said shaft is supported in suitable bearings b from a bed-plate B. Differential pulleys 7, 8, 9, and 10 are fixed on shaft 2 between said bearings. Any suitable shaft arrangement may be used for the arbor, whether as shown or its equivalent, the essential thing being asuitable arbor to wind the lining upon in the first place and then to unwind it into the can and suitable means to operate the same with instantaneous reversals according as one or the other of the two operations is to be per formed.

The drive mechanism for the arbor proceeds from any suitable source, such as a counter-shaft D or the like, the especial shaft D in this instance being supported in suitable hangers cl and carrying differential pulleys 11, 12, 13, and 14, which are in line with pulleys 7, 8, 9, and 10 below, and a belt E runs on one or another set of these pulleys, according to the speed wanted.

Furthermore the arbor requires reversal to effect, first, the operation of winding the lining G thereon, and, secondly, the operation of unwinding it therefrom into the can or jar H. Hence the arbor runs in one direction for one purpose and in the opposite direction shown) and belt L may be regarded as a crossed belt from such line-shaft, while belt J is, say, uncrossed.

As seen in Fig. 1, these bands are each running on a loose pulley M and N, respectively, and between them on shaft D is the tight pulley P, to which either band may be instantly shifted by a treadle mechanism in control of the operator at the arbor. Thus belt L is controlled by treadle 15 through cable 16 over suitably-arranged sheaves 17 and 18 to hanging lever 19. Said lever connects with a belt-controlling rod 20 provided with fingers 21 at opposite edges of belt L, and, extending through hangers d, has a spring 22 at its opposite end, which normally draws said rod in that direction and holds belt L on its own loose pulley. Hence belt L runs idle till it is forcibly carried onto fixed pulley P by the said treadle-controlled beltshifting mechanism, and the instant the treadle is released spring 22 carries the belt back again onto pulley N.

Suitable means are provided for controlling belt J, comprising treadle 24, cable, cord, wire, or the like 25, sheave 26, hanging lever 27, rod 28, and fingers 29 thereon at opposite edges of belt J. A spiral spring 30, wound about the opposite end of rod 28, holds belt J normally on loose pulley M, and said belt takes the fixed pulley P only when drawn over thereon by its treadle-controlled mechanism. Hence, also, the arbor-shaft is at rest when neither belt is at work, and, as suming that belt J is used to wind the canlining on arbor A, it will be thrown out automatically and instantly by spring 30 when the operator releases treadle 24. On the other hand, belt L will be thrown in when treadle 15 is operated and the arbor is re versed, and the change of arbor from one direction of rotation to the other occurs as quickly as the operator can change treadles.

about the arbor is being effected the next moment the lining is being unwound from the abor into the can, and so rapid are these operations in the hands of an expert that as I many as six thousand cans can be lined as a single days average task, or, say, six hundred per hour.

Any convenient arrangement of belt shifting mechanism may be employed, and if hand-shifts be preferred they can be used without departing from the spirit of the invention.

In transferring the lining from the arbor to the can or cell the operator presses the can onto the lining and it is taken up by frictional contact and pressed into place, as in Fig. 4, almost instantly, the revolving of the arbor being very rapid.

By bringing the sheet of lining square against disk or wall 5 and then squaring the cell or can thereon the two are brought together in true relations.

The designation of rubber as a sleeve or surface for the arbor is to be understood as including an equivalent frictional material which will serve as an adhesive for the lining wrapped thereon and without which the arbor would not perform the function described.

What I claim is;-

1. In means for placing linings in battery cells, a tubular arbor having a rubber surface and a wall at right angles to said surface at the base of the arbor.

2. In means for lining dry batteries, an arbor comprising a shaft having an exposed end and a rubber-surfaced tube sleeved over said exposed end and a disk-shaped wall at the inner end of said tube fixed on said shaft, in combination with means to rotate said shaft in opposite directions alternately, and means to shift the said mechanism.

In testimony whereof I sign this specification in the presence of two witnesses.

PHILIP P. NUNGESSER.
