TELEPHONE DESK SET. I

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application filed April 10, 1908. Serial No. 426,205.

To all whom it may concern Be it known that I, CLAUDE D. Enocns, i lower end of the standard, and the supporta citizen of the United States, residing at La Crosse, in the county of La. Grosse and State of Wisconsin, have invented a new and useful Telephone Desk Set, of which the following 1s a specification.

. ly invention relates to improvements in telephone desk sets employing a stand, a transmitter support and a receiver switch hook.

In the use of my invention be easily and quickly taken apart and assembled and the construction is strong, rigid and durable and less liable to disorder than with instruments of its kind, heretofore used.

My invention is simple and inexpensive in construction and the parts can be easily and quickly renewed or repaired when worn and the electric connections uncovered.

In the accompanying drawings forming part of thisspecificatiofi,Figure l is a' perspective view of my improved telephone view of what I have chosen to term the unit supporting the transthe parts can mitter and removed from the shell of the stand; Fig. 3 is a detail longitudinal section taken on the line XX of Fig. 2; Fig. 4 is a detail side view of the stop'plate, switch springs, tie-rod and switch. push piece in the shell of the stand; Fig. 5 is a side view of a lower detail portion of the stand; Fig. 6 is an enlarged sectional view line YY of Fig. 5; Fig. view of the stop plate used stand; Fig. into the base of the stand, the base plate be.- ing removed, and Fig. 9 is a vicw'li'ioking at the lower end of the-hollow standard.

In the drawings A represents the stand of my improved telephone desk set which appears of usual exterior design.

represents a transmitter of ordinary form, (J a receiver and l) a receiver hook.

The stand is provided witl a hollow base 2 and a tubular standard 3, the latter fitting snugly into an opening 4 in the shell of the base and being provided with a circular shoulder 5 which supports the hollow standard upon the base. Adjacent to the lower end of the standard and resting fiat against 7 is a perspective in the base of the the inner surface of the hollow base is :1

stop plate in the general form of a, circular perforated disk 6 which is provided with a pairof upwardly extending detents 7 -pro- 'ard and plug taken on the 8 is an enlarged view looking jecting into oppositely disposed slots 8 in the ing shoulder 5 thereon. The detent-s on the stop plate serve to lock and assist in rigidly securing the hollow base and standard to gether. I

At the upper end of the standard is a head piece 9 which is formed with aplug fitting snugly into the standard and a circular recess 10 into which the end of the standard projects and by which the standare .socketed together. Extending between the plug or head piece and the stop plate 5 is a tie-rod 11 which isthreaded on its upper and lower ends, the upper end being screwed into the plug and locked by the nut 12 and the lower end passing' through the stop plate 6 to which it is secured by means ,of the space nut 13. In this manner and by the construction above set forth the head piece, hollow standard and hollow base are secured together and can be easily and quickly taken apart'and assembled.

The lower portion of the hollow base is closed by a base plate 14 in the form of a disk, through which the lower extremity of the tie-rod 11 passes and is secured against the space nut 13 by a nut 14. The base plate is recessed at 15 to receive the nut 14 below the surface thereof. The nut 14 serves to lock the space nut and prevent it from unscrewing as well as to'hold the base plate securely against the shell of the hollow base. Upon the peripheryof the base plate is a ring 16 made of leather or other suitable material which is used for the purpose of preventing the base of the instrument from marring furniture upon which the desk set may be placed. This ring impinges against the inner wall audits surface projects below the lower edge of the shell of thc'basc. The inner portion of the leather ring is slotted longitudinally and the perimeter of the base plate is fitted into saidslot to hold 100 the ring upon the plate. The ring may be in the form of a ointed strip or band as may be desired.

The stop plate 6 is formed with a hanger 7 upon which are mounted switch springs 18 and 19. These springs are adapted to be connected to open and close the circuit of the instrument. They are secured upon the insulating strips 20 by means of screws 21. The lower switch springs are connected.

taken off of its hook and the tip 31 thereby spring 19 extends beyond the upper oneand in the path of a push rod 27 which will he hereinaftermore fully described.

he switch hook D of ordinary construction swings up and down in a slot 22 in the head piece in which its. shank is pivoted upon a pin 23 and limited in said movement by shoulders 32. The upper end of the standard has an opening d6 through which the shank of the switch hook passes freely. Impinging upward against the lower edge of the shank of the switclrhook and sliding through an opening 24 in the head piece and through a guide 25 which is secured between nuts 26 on the threaded lower end ofithe tierod is a pusl rod 27. This push rod slides parallel to the tie-rod and is provided with a shoulder 28 between which and the guide 25 is an expansion spring 29. The function of this spring is to raisethc pushrod and switch hook and to open the. switch springs in the base when the receiver C is removed from said hook. The lower end of the push rod passes freely through an opening 30 in the stop plate 6 and is provided with an insulating tip 31 which impinges against and depresses the switch spring 19 when the switch. hookis down, thus separating the switch springs in the base of the instrument and opening the circuit with which said When the receiver is raised out of contact with the switch spring 19,'the switch springs close together as illustrated in Fig. 4 of the drawings and close the circuit with which they are connected.

The head piece 9 is provided with the usual transmitter support 33, to which the transmitter is adapted to besecured such as screws 34. This transmitter support is oined to the head piece by a. pivot connec tion 35. The electrical conductors 36 leading from the transmitter pass through, an

opening 37 in the transmitter support, and an opening 38 and branch openings 39, the latter in the head piece, leading into the hollow standard, through which said conductors are passed into' the base. The head piece or plug in the hollow standard is cut away at 40 to form an opening through which the conductors may pass freely from the head piece into the standard.

Depending from the stop plate in the base is an insulating terminal block ll which is secured thereto by means 0*? screws l2. Terminal pieces 43 of usual form are mounted upon the terminal block by which any desired connection may be made with condnctors leading from the outside circuit, re ceiver and transmitter. The cont luctors leading from the. transmitter through the shell are brought down to the switch springs hrough openings-ll Millie uctors leading 'l'roxn i and tern'iinals li i stop plate. The eond the receiver and outside circuit are led lllltt the base in the usual manner through an lIlsulating bushing 45 which is secured through an opening in the wall of the base.

In use when the receiver is taken off of its hook the push rod is automatically raised into superior position by means of the spring" into the position shown in Fig. 41 of the drawings. When the receiver is hung upon its hook the push rod is depressed and the switch springs opened into the position illustrated in Fig. 6. When it is desired to take the telephone set apart the nut 14' is removed and the base plate taken off of the tie-rod 11. The space nut 13 is then removed and the remaining parts of the instrument separz ted.

It will be noted that the manner of associating the parts illustrated in Fig. 2' together as a unit which can be separated without disturbing any of its parts from the stand and of clamping the standard, base, base plate and support for the switch s rings amt-terminals together, produces an e ective and etticient means by which the telephone set can be easily and quickly taken apart, for the purpose ot making adjustments and repairs, and a rigidt'rame for-supporting the working parts and it reduces the liability of the instrument to disorders to which instruments of this character are subject. I
