CLIFFORD M. WATBOUS, OF EAST HAMPTON, CONNECTICUT, ASSIGNOR TO GONG BELL MANUFACTURING COMEANY, A CORPORATION OF CONNECTICUT.

TOY TELEPHONE TRANSMITTER.

Application filed May 13,

' of East Hampton, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Toy Telephone 'Iransmitters, of which the following is a description.

This invention relates to toy telephones and is particularly related to the transmitter employed in an assembled device in conjunction with a base, standard, transmitter and receiver with appurtenant parts, all in simulation of a standard type of telephone.

Usually, these toy devices have some signalling or sound producing mechanism which can be operated by the child in play, to approach in operation, the effects of a telephone.

In a co-pendiug application, Serial No. 566,903, filed June 8, 1922, I disclosedand I claimed a telephone transmitter having certain features of advantage and'the present invention is directed to special features of such a transmitter which in manufacture, have been found to improve the art of production and provide a more substantial element.

In toy mam-ifacture, it is essential. to secure appearance of the highest character, in conjunction with stability, as toys ordinarily receive rather rough usage.

It is in the elements of advantage to the article and advancement in the art of manufacture, that the essence of the present invention resides.

For purposes of illustration, the transmitter is illustrated, in conjunction with a desk set, in simulation of a standard type of telephone;

The main object of the invention isto produce a transmitter, component parts of which may be readily fashioned, assembled and secured in interlocked arrangement and without liability of buckling of the parts through lack of skill of the operative during assembly.

Referring to the drawings:

In the manufacture of toys of the type herein described, the essentials are economy in stock simplicity in formation and as sembly of the parts and sturdiness of the completed article. At first sight, these requirements would seem to be easy of accomplishment, but it has been found, in actual manufacture, that what are apparent- 1y slight details, become allimportant factors in actual manufacture of high' grade goods meeting the above qualifications.

Utilizing the invention as expressed herein, con'iparatively light stock maybe employed which when submitted to the action of dies or spinning operations, gives a uniform product which permits of high production. This stock is so utilized with various elements that assembly may be effected even with unskilled labor. Provision is made through the elemental functioning of the parts to obviate liability of imperfect goods which wouldordinarily occur in assembly unless the assembly were made by skilled labor and with great care. In fact, the elements must be reduced to a form in which they may be stamped out and spun up, spun together, interlocked and clamped, one with reference to the other, without requiring trimming, fitting and particular care in the assembly.

Referring to F gure 12, there is illustrated a transmitter having the general elements of those heretofore described in my prior ap plication.

There is a supporting bar 1, which, as illustrated, is stamped out in a form to afford an abutment 2, against which the shell 3, of the transmitter may rest.

There is a closure for this transmitter, which as illustrated, is in the form of a disk 4, and there is a mouthpiece 5.

It is essential that these various parts be bound together to form a stable structure and to effect this, the bar 1, extends through the plate 4, and mouthpiece 5, these parts having suitable slots or openings for the purpose. The end of the bar is then swedged down so that the shell 3, and closure, consisting of the disk 4, and its mouthpiece 5, are firmly interlocked against the abutment 2, of the supporting bar 1.

In my prior application, no particular provision was made for preventing buckling of the parts when the swedging tool deformed the metal at the end of the bar 1, and this resulted in some loss during production.

Over zealous operatives would often dopress the swedging tool to such an extent as to either buckle the closure plate, mouthpiece or the shell. Y

Even where assembly was effected in a proper manner, there was still objection inasmuch as the closure plate 4, was liable to shift with reference to the base 3. This occurred at times during assembly and even after assembly, if a toy were dropped so that the disk 4, was given a sharp blow it was liable to distort the assembled parts. 7

In order to prevent slippage of the clo-- sure plate 4, such an arrangement as illustrated in Figure 12, is desirable and this may be used with, or without the stop block hereinafter specified. hen used with the stop block, there is assurance that there will be no buckling of the parts during the swedging operations. Vhen used without the stop block, there is no opportunity of slippage between the baseand the closure plate, inasmuch as the latter is centered by its annular rim hereinafter described.

To overcome these objections, I now cinploy a stop block 6. This may be of cylin-' drical form and is slipped over the outer end of the bar 1, after the shell 3, has been assembled thereon. The closure, consisting of the plate 4, and mouthpiece 5, are also slipped over the end of the barl, and rest upon one end of the stop block 6.

It follows that there is a substantial abutment surrounding the bar 1, and against which the upsetting tool for the end of the supporting bar 1, may impinge to a considerable extent without liability of buckling any of the parts.

This arrangement has unusual advantages as it speeds up manufacture, assures perfect goods and adds comparatively no expense. The stop blocks may be formed of any inexpensive material such as a wood block.

This stop block is particularly advantageous in conjunction with the various forms of transmitters illustrated. In Figure 4, the shell of the transmitter is composed of two parts, 7 and 8, which are stamped and spun up. The base part 7, of the shell, has a lip 9, of sufficient length to be spun over a flange 10, of the co-operating part 8.

In assembling, the bar 1, has the lower section 7, stop block 11, co-operating sec tion 8, and mouthpiece 13 arranged thereon and the deforming tool then upsets the end 14, of the bar to secure the elements in fixed position on the bar 1. The edges of the two parts of the shell are spun one over the other giving an extremely firm constructioi'i and one of very attractive appearance.

Very light metal may be employed in this form of device as the annular ring or rim, formed by spinning the parts together, surrounds the transmitter and acts as a still"- ener to prevent displacement, buckling or dentin'g of the thin metal.

The supporting bars for the transmitters may be of any desired form. In Figures 1 to 4, they are shown as stampedfrom shcct stock and they may be perforated fora pivot to be attached tothe standard or may be stamped out of an. angular, piece, all to suit the exigencies of any particular requirement.

In Figure 7, there is illustrated a bar which has all the necessary features for an abutment against which to bind the parts of the transmitter. In this-figure, a blank is formed from thin sheet and folded upon itself as on the dotted line, causing its two parts to be superposed so that a cutout portion of the blank will provide a shoulder 12, at the properdistance from the end of the bar 15. The end of the bar 16, may be suitably formed so that it may be swcdgcd down after the shell parts, mouthpiece, etc, are in place thereon.

If it is desired to form a distinct shoulder for an abutment at opposite sides of the bar, which of course, is preferable, the die will strike out or deform the metal as at 14 so that the end of the folded section as at 12, will form a shoulder on one side and the deformed part of the body of the blank in line therewith, will be offset at the opposite side.

In Figures 8 and 9, this same result may be attained by striking out a long body part 17, and a shorter body part 18, and then. superposing the two parts, spot welding the thin. metal to form a plate bar, as shown in Fig. 9, which will have abutn'ients 19, 20, against which the shell may be bound.

Hit)

lnzlieu-of the form shown in Figures -7 to 9, lugs may beupset 1n the body ofthc bar 21, as at 22, 23, one being throwntoonc side ofthe bar while the other 'isthrowntothe oppositeside thereof. This obviouslywill give an abutment againstwhich theswedging operation may occur for binding the parts together. These various forms of supporting bar describedmay be used with facility in conjuction with the stop block which acts as a take up "and spacer between the elements to be assembled when the swedging tool deforms the end of the bar to permanently lock the parts together.

In Figures 5 and .6, in place of using the conventional flat stock, rod stock of appropriate size may be employed in Which case the outer end, provided it is to be tation, and lateral movement.

In Figure 12, there is the same elemental arrangement as in the above described devices.

The form of the closure plate 50, however, instead of being a flat plate, as heretofore illustrated, has a depression 51, concentric vith its periphery and so formed that the depressed metal forms an annular like ring 52, which surrounds the outer edge 53, of the. basepart 3.

This annular ring centers the closure plate 50, on the base and materially stitl'ens the plate so that it may be secured in place without difficulty by swedging the end of the supporting bar 1.

There is no objection to using this dcformed plate, iii so far as appearance is concorned, as in all of the structures, there is the celluloid or similar disk A, which covers the plate and carries the trade name and other suitable indicia and this, of course, covers the groove 51, giving a neat appearance to the device.

It will be obvious, from the above, that while an abutment on the bar acts as a stop for the shell of the transmitter casing, such an abutment, in conjunction with a stop block, opens a wider field for manufacture, as any of the forms of bars hereinaboi 'e described may be used successfully with such a stop block.

There is no difficulty in making the parts of the shell with exactitude, as of course, these are struck up on dies or spun up as the case may be, with exactitude. lVhen they are assen'ibled, as hereinabove described, in conjunction with the stop block, there is practically no loss dueto'improper assembly and careless use-of swedgingtoolsdn locking the parts together upon the bar.
