' Application filed May 3, 1907,. Serial No. 371,641.. Renewed March 28, 1912. Serial No. 686,970.

To all whom, it may concern:

Be it known that I, \VILLIAM Kaismno, a citizen of the United States, residing at Chicago, in the county of Cool: and State in so-called automatic telephone exchange 7 systems.

In such systems,the substation equipment includes the usual telephone transmitter, receiver, switch-hook and astransmitter which commonly possesses considerable size and weight, relative to the other parts of the equipment. In the deskstaiids heretofore proposed for use in automatic systems, the parts of the stand have been so arranged that the center of gravity of the structure has been relatively high, with the result that the stand has been easily upset with consequent damage to the equipment, and especially to the transmitter mouth-piece.

One of the objects of the present invention is to construct a deskstandfor use in automatic telephone systems, in whichthe center of gravity will be so low that it will be very diiiicultlto overturn the stand.

Another object of the invention is to so construct and arrange the parts of the stand that it will present a symmetrical appearance while maintaining certainty and efficiency in operation, simplicity in construction, and economy in manufacture.

In developing the invention with these general objects in view, I have devised certain novel features, many of which are capable of a more general application than I have herein disclosed. These features include a novel mechanical connection between the transmitter and itssfrpport, the arrangement of a friction strip at the extreme outer edge of the lower plate of the base of the structure, a novel casing for the signal mechanism forming a portion of the base of the stand, novel finger-hold mechanism, a novel arrangement of parts by which the spring contacts are readily accessible 55 for repair and removal, novel means for ac ituating certain of the spring contacts, a

novel arrangement of connections between the switch-hook and its cooperating spring lcontacts, and a novel general arrangement of the various parts of the calling mecha- {nism. All these various features and the imany advantages of the structure will be more fully understood upon reference to the 3 following detailed description taken in connection with the accompanying drawing, j and the scope of so much of the invention as 1 is claimable in this case will be particularly 1 pointed out in the appended claims.

In the drawing, Figure 1 is an elevation of a desk-stand constructed in accordance with the present invention, parts being 1 shown in section and broken away for clearscciated parts, and in addition, a signal;

tained in the base A.

Throughout these views, like characters refer to like parts.

Referrin to the drawing in. detail, it will be observe that the desk-stand includesa base A, which is preferably circular, a standard B, preferably extending from the center of said base, a transmitter C pivotally secured to the upper end of the standard, and a switch-hook D pivotally secured to the standard B near its upper end and operatively connected to the mechanism con- The transmitter C may be of any preferred construction and in itself constitutes no part of the present invention. T he standard B is made hollow to reduce the weight of the upper portion with a of the structure and to permit the passage of the conncctirl-n between the switch-hook and the mechanism in the base and preferably comprises an inner metallic tube 10, an outer tube 11 of rubber, ebonite or other suitable insulating material, a metal cap 12 located at its upper end, and a metal bracket13 located at its lower end. The cap 12 is provided with a suitable opening or passage 14 through which leads may extend from the.

transmitter terminals to the interior of the standard B, from which point they are led through the base, as hereinafter more particularly pointed out.

One feature of the invention consists in the connection between the shell 15 of the transmitter and the'supporting cap 12. According to this feature, the upper end of the cap is provided with a transverse in which is rigidly secured to the cap, pre erably by means of screws 17 andthe plate 18 and the adjacent portion of the trans mitter shell 15 are arranged to ti 'htly engage the pin 16 to thereby provide a frictional connection between thetransmitter and the standard so that the transmitter will remain in any position to which it is moi-( d by the user of the instrument. The shell composed of springy material wl'iich is punched out in themanner indicated in Fig. 2 to provide a bearing surface for the pin and the plate 1.8, which in- .he present case more rigid, is provided .iilar hearing for the pin 16; but these surfaces are so constructed that, without subjecting the shell to flexure, the portions of the plate and shell on either side of the pin 16 will not come into engagement with each other when the pa ts are assembled. but, by means of the 19, the shell 15 and plate 18 are drawn together and th adjacent portions of-the shell 15 are thereby flexed slightly and a good frictional engagemen between the pin and its clamping members is therel'*:, ine t. in the present instance, the Vi of the cap 12 is of spherical form uthi enters a circular opening in the shell and the plate 15. Obviously, this same in turn again secured to the uiiderside of the adjacent portion of the cap 1:2 by screws 22. This bracket serves as, a support for the switch-hook D which is ivoted thereto at the point' 23. The switch-hook extends through a suitable opening 24 in the opposite wall of the standard, and a connecting rod 25 is secured to the'switclrhookat a point adjacent to this opening and extends downward through the interior of the standard into operative relation with the call, mechanism in the case A, as will be herelnafter more fully pointed out. The metal bracket 13 at the lower end of the standard 33- is secured to one side of the centerof the base A, preferably by screws 26, to the top of the top plate 27 ofvthe basal casing. By this arrangement, the lower end of the standard overhangs the center of the base and suflicient space is left between it and the top of theplate 27 for the passage of a late 28 which forms part of the fingerho d mechanism by which the signal mechanism within the case is actuated. The por- .tion of the "bracket13 which is secured to the plate 27 also serves to limit the movementof the finger-holdanechanism by engaging at its 0 posite sides the opposite sides of the plilte 28. The finger-hold mechanism includes, in addition to the plate.

28, an arcuate plate 29 having a downward projecting flange adapted to rest upon a similar arcuate plate 30 whose flange extends into close proximityto the top of the plate 27. The plate 30 is provided at its top with a series of openings 31 and its flange is notched at 32 so as to allow t-he passage of a stop-pin 33 when the finger hold mechanism is operated. The outer flange of the plate 29-is provided with a series of openings 34 through which the outer ends of a series of finger-levers 35, serving as finger-holds, are adapted'to pass. These finger-levers are L-shap'ed and are, in each instance, pivoted, at the angle, between the horizontal portions of the plates 29 and 30, and their inner ends are turned down through the openings 31 inthe plate 30 so as to provide stop projections 36, In' each instance, the finger-lever is held normally by a sprin 37 so that its stop projection 36 lies in t e outer portion of the openin 31. When in this p0sitiori,'as clearly ind1- cated by the dotted line extending through the stop-pin 33, the stop portion will not engage the pin 33 when the finger-hold mechanism is operated, but it will be apparent thatwhenever any particular fingerand the upper ends lever is pressed by the finger for the purpose of operating the finger-hold vmechanism, its stopprtuection Will be moved into the inner portion of the opening 31 and into a path which will cause it to engage the stop-pin 33, provided the finger-hold mechanism is moved far enough. In additionto the plates '29 and 30. the plate 2t) covered by an escutcheon plate 38 which is preferably secured in place by bolts 39. This escutcheon plate is adapted to hold in place a card or other device on which designations, corresponding to the finger-hold levers, are marked. In the operation of the mechanism, as is usual in such devices, the lever opposite the particular designation wanted is pressed by the finger in order to rotate the finger-hold mechanism, and the extent of this movement in each instance is determined by-the particular linger-lever depressed, since the displaced lever is the one which engages the stop-pin The top plate 27 of the base forms the main supporting platlr tor the mechanism contained within the base: and as clearly illustrated in the drawing, this mechanism is supported through the agency of four supporting posts l0-41-2l-2-43. which are firmly secured to the top plate in any pre- ;3() ferred manner and extend downward. into close proximity to the upper face of the bottom plate 44 of the casin Suit-able screws, passing through the case from the bottom and threaded into the lower ends of these posts,serve top plate is provided with a peripheral groove 45, and the bottom plate 44 is provided with a similarly. disposed upturned ,fiange 4c, tboth of which engage the peripheral wall 47 of the casing and firmly hold it in place. \Vith this construction, a substantially dust-proof casing is provided. For the purpose of providing a suitable guide for the electrical conductors entering the,base A, the wall 47 is cut away slightly as to enable a guide ring 48 to be used. This guide-ring 48. and a-second guide-ring 42? are. struck up outof a strip of'metal which is held in place between the plate 27 of the posts 4041. as clearly indicated in Figs. 5, 101 and 11. In order to still further increase the stability of the structureover that avhich results from lowering itsfcenter of gravity, the bottom plate' ii is struck up so as to provide a gZOOVG- 50 atits extreme outer edge; and into this groove, is inserted a strip 51 of leather. felt. or like fibrous material which,

, when the stand in use, engages the supporting surface upon which the stand u ting and tends to prevent its cli ready rotation in case of accioe *3;- The strip points to lllOlCl the parts together. The

The mechanism. contained within the casirg formed by the plates 27. 44' and i7. cmnpriscs, in general, gear mechanism which is located between the plate 27 and an auxiliary supporting plate and coutact mechanism which mounted on the lt wer side of said auxiliary supporting plate. -For the purpose of operatively connc-cling the finger-hold mechanism located above the plate .27 and the gearing located below said plate, a hollow shaft 53 is provided. This shaft is journaled in the plates 27 and 5.12 and is provided with an opening throughout its length, through which the lower end of the rod 25, connected, previously described, to switch-hoolt' l), extends into operative relation with a sct of spring-contacts a which is supported near the outer edge of the auxiliary supporting plate 552. This set includes spring-contacts snlated from each other and provided with proper connection terminals. As clearly illustrated in Fig. 7, contact-I56 is longer than its fellows and it is this contact which 'is engaged by the rod 25 to vary the connections of the contacts. In order to prevent electrical contact between the rod 23 and contact 56, the latter is provided with a suitable insulating button 59. which the end of the rod '25 is adapted to engage. The upper end of the shaft 53 is sccm'ed to the linger-hold frame 28 in any suitable manner as by means of the collar 60 and the not 6. cooperating therewith. The lower end of the shaft carries an actuating or impulse wheel 62, provided with a series oftceth .33 arranged in themanner indicated in Fig. 5, which is rigidly secured thereto so as topartake of the movement of the shaft. and the finger-hold mechanism. is also provided with a driving-spring fitwhich secured at, one end to the shaft,

in turn is secured to the auxiliary plate. \Vith this arrangement, the moueinent. of the fingerdiold mechanism places the sprin'r under tension and it tends to return the shaft and its associated parts to normal position, which is that illustrated in l airing the set of contacts to the plate 5-l-55-5657-58, which are suitably in- The shaft 53 and at its opposite end to a case (15 which Fig. l in which the right side of the bracket and it supports an insulating strip which separates it from the contact- 68 and also supports the insulation which separates the contacts (EFF-67. Contact 66 is longer than its fellows and is normally engaged by a pin 70 carried upon the actuating wheel U2 and located so as to maintain the contacts t3t3-(3768 out of engagement. Due tr the inherent tension of contact 26. however. as soon as the wheel (32 is moved from normal, these contacts are brought into engagement. The sets of contacts s's are substantially identical and each comprises a rigid supporting strip 71, a fixed contact 72, a spring-mintact 73, and a pivoted actuating member 74. The sup 'iorting strip 71 is pro:

vided with a tlange by which the set is secured to the auxiliary plate 52 and it also has a laterally extending lug 75 between which and the bottom flange is pivoted the actuating member 74. This member is pro vided with a tension spring which is coiled about its pivot 76 and normally tends to hold it against the stop-pin 77. p

.t bloekof insulation 78 serves as a spacer between the member 74 and the spring-contact T3. The strip-.71 and contacts 72-73 are suitably insulated from each other and the contacts are provided with suitable COD? ucction -terminals. The tension of the spring-contact 7 is such as to normally maintain contacts 7'273 in engagement. The actuating member 74 is provided near its free end with lugs 79 between which is pivoted a triangular engaging'member 80. This engaging member is'so constructed that upon the movement of the actua'tingwheel G2 in the direction of the arrow in' Fig. 5,-it will rock about its pivot without separating contacts 7'2-T3; but upon the reverse movement of'the wheel. these contacts will be "disengaged and engaged upon the-passage of each tooth. This action is clearly illustrated in Figs. 8 and '9. As shown in Fig. 8, upon the forward movement, the portion of the member 80, which normally lies in entime consumed between the separation of the contacts and their subsequent engage ment may be increased by adjusting the position of the set upon the plate as to move the member 80 nearer the shaft 53, and may be decreased by adjusting the set so as to move said-member farther from. 'said shaft. in orderthat the 'member, 80

will return to its normal position after movement to the position illustrated in Fig.

8, it is provided with a small returningconnected to a governor 83. Any referral type of governor may be employer for this purpose and in the resent instance I have illustrated a centri igal governor of the ball type. As clearly illustrated in Fig; 12, the governor shaft is journa-led between the top plate-27 and a bridge 8}; which unites the supporting -posts 42-43 and which is adapted to be adjusted through the agency of nuts 85-86, threaded'upon said posts. In the action of the governor, asdbe balls fly outward, they tend to depress the disk 87 downward in opposition to the upward pull of the springs 88. The diskST iS adapted to engage friction blocks 89 of cbonite, rubber or other suitable material, carried by the bridge As clearly illustrated inFig. 13, the position ofthe lowerbearing of the shaft of the governor may be nicely adjusted by mea'nsiof the, sere ao threaded into the bridgeStand'Iretained in the desired position by.t'he lock-nut tll'. .The

operati vely connected to the shaft 53by a suitable train of gearing, including pinion 93 and gear-wheels 94 95.' In order t-hat the governor may be brought into action onlyupon the return movement of the shaft {33 and. its connected parts, a clutch is, rovid'ed between said shaft and the gear-w eel 95, whiehis loosely journaled upon the shaft pinion 92 on the shaft, of the governor is;

53. This clutch comprises an arni .96 fined to the shaft 53 and carrying at its outer end a pawl 97 which is provided "yi'ith a springtending to throw its engaging end into engagement; with the teeth of the gear-- wheel 95. Upon the movement of the arm 96 in the direction of the arrow in FigftO; the pawl 97 slipsout of engageinentu'ith the tecth and readilypasses over them'witlhout actuating the gear-wheel J5: bubupmt the return movement, caused by the drivingspring 64. the motion of the arm 96 is communicated to the train of gearingand thereby to the governor. 'By the engagement of the disk 87 with the friction blocks 89 of the govern r. the return movement of the shaft 53 and 'its associated parts is retarded so as to provide. a proper interval of time between the successive operations of the actuated spring-contacts.

In order to prevent the. manipulation of the finger-hold mechanism prior to the removal otthe receiver from the switch-hook D, an elcetr'omagnet 98 is mounted between the main and auxiliary supporting plates 27 and 52 in a position to control, through its armature mechanism,- the initial opera tion of the shaft 53. This electromagnet has an angular armature 99 which is normally held in a retracted position by a spring 100 and which cooperates with an obstructing arm 101 to control the movement of the arm 90. The end of the arm 101 extends downward so as to lie normally in the path of movement of the pin 102 forming, in the present instance, .an extension of the pivo tal pawl 97 but when the armature is attracted, this arm 101 is thrown out ofengaging position and the arm 9-6 may be freely rotated. This/electromagnetis conveniently disposed with reference to the other partsof the mechanism and may be readily gotten at for purposes of repair or substitution. As clearly illustrated in Fig. 10-, the condenser 10% of the subscribers setmay be convene iently located on the oppositeside of the shaft from the electromagnet 98 in compact relation with the various parts of the mechanism and clamped against the top plate 27 by a screw 103 threaded through the auxiliary plate 524 For convenience in maleing'electri'cal con uections to the various parts of the apparatus, a bridge 10% of insulating material is ar-' ranged between the supporting posts 40- 11 to the opposite side of the shaft 53 from the bridgeS t'and provided with aseries of terminals 105. With this arrangement, the

- connections within the instrument may be made between the Various contacts and these terminals and external connections may be made at any time with these terminals.

In extending the telephone transmitter leads from the standard B to the contacts on the in'idge 105, they are preferably led. through a channel 105 extending through the bracket 13; at the base of the standard and a registering opening 105 in the top plate 27, the former being indicated in dotted lines in Fig. 4, and the latter being partially shown in Fig. 5.

In order to illustrate one application of the invention, I. have provided Fig. 1 1 in which the various elements of the mechanism heretofore described are diagrammatically illustrated. According to this dia-- gram, the substation, which is designated M, is connected by line limbs PS with-putomotic switch mechanism at'the exchange, designated As far as possible in this diagram. the same refer- 1 ,e characters are used licrcto't'm-e, in oro'tito connect the parts ot the different figures with the diagram. Tu operation, a party at substation M, desiring to obtain connection with a line running to some other substation first removes his receiver 106 from the switch-hook D. thereby interrupting the normal circuit between contacts 54-55 and closing a cir- ('uit between contacts 57-58. In the mechanical construction, this is.brought about throughthe agency of the rod 25 which extends down through the stanidartland the hollow shaft 53 into engagement with the spring-contact 56. While the receiver is on the hook the contacts are in the position illustrated in Fig. 7; but upon removing the receiven contacts 56'57-5S come into en gagemcnt. The closing. of contacts 57 completes awcircuit from the live pole of the battery B at the central office through relay 107, line limb 1, contacts 72-73 of set 8 transmitter" C, contacts 5857, Winding of electromagnet 98, contacts 7273 of set 8', line limb S, relay 108, through battery B to the grounded pole of battery B, The closing of this circuit energizes electromagnet 98 at the substation to attract its armature 99 and thereby unlock the impulse wheel 62 and the connected finger-hold mechanism to allow the same to be manually operated. The closing of the circuit also energizes relays 107 and 108 of the switch mechanism at the central ofilce. The energization of these relays opens contacts 109- 110 of the circuit for the release magnet RM, and the energization the same relays opens contacts I11-112 and closes contacts 113-11et. With the contacts in this position, it will be observed theta. circuit for primary magnet M extends from the live pole of the battery B through the winding of said magnet to open contact 111, and thence through closed contact 114 to ground. A. similar circuit extends from the live pole to the battery B through the winding of secondary magnet SM to open contact 112, thence whi-ch the wipers are moved to a desired bank contact by partaking of movements in two directions. a primary direction and a secondary direction In the diagram. the wipers115116 represent two of the wipers of'su 'h a switch which are adapted to receive their primary movements by the repeated momentary cnergizations of primary magnet PM. and their secondary movements by the similar energizations of secondary magnet SM, and to be restored to normal at the end of conversation by the cn'ergization of release magnet RM. In this diagram,

' contact 11.7 is the contact of an otl'-normal switch which is adapted to be closed upon the first primary movement of the switch parts. Such switches are Well known in the art and it seems unnecessary to refer to them more specifically. 'Having now removed the receiver and thereby unlocked the calling mechanism, the calling party now actuates his finger-hold mechanism to transmit the impulses necessary to make the desired connection. Although there is but one switch shown, it will be understood that in the use of the invention in automatic or semiautomatic systems, there will ordinarily be a series of switches set in operation in making each connection. Assuming that itis desired first to transmit six impulses over the line, the sixth finger-lever from the bottom, as seen in Fig. 4, will be depressed and the frame'28 carried around until the stop projection 36' on the depressed lever engages the stop-pin This movement will be far enough to carry six teeth 63 of the actuating wheel 62 beyond the engaging member 80 of the sets of the spring-con tac'ts; then upon the removal of the finger from-the engaged lever, the actuating wheel 62 will be returned by the spring 64; and during its return movement, the contacts 72-73 of the set 8 will be broken six times, followed by a single break of'the contacts 72-73 of set a. 4 The six impulses will momentarily deenergize relay 107 six times and thus momentarily energize primary magnet PM six times and thereby step the wipers 115116 six steps in a primary direction. The single'following impulse will denergize electromagnet 108 once with a consequent momentary single energization of the secondary magnet SM. It willbe seen from the diagram and mechanical drawing that the first movement of the impulse-wheel 62 will ground the line limbs PS at the substation by way of contacts 66-6768. Thus the energizing circuits for the relays 107- 108 will then extend from the live poles of the batteries Bl3 over the line limbs P and S respectively, to this, ground. It will be understood that the switch construction, diagrammatically illustrated, is such that the single impulse following the six impulses will start wipers 115116 in a secondary direction and they will continue this movement until an idle trunk is found. Since the extension of the calling partys circuit through other switches calls for the same operation of the calling mechanism, it will be unnecessary to go further into a detailed description of such operation. After each operationsof the actuating wheel 62, the ground is removed from the line limbs and the contacts of each set ss are returned to normal. At the end of conversation, the restoration of the receiver to its hook restores .the contacts 54-555657 58 to their normal position, thus interrupt ing the circuit through relays 107.-108 simultaneously, and thereby through their contacts 109110 completing a circuit for the release magnet BM from the live pole of battery B through the' winding ofsaid magnet, ott'normal contact 117 and contacts 109110 to ground, thereby restoring the switch parts to normal. It is believer that this diagram, although fragmentary, will make the operation of the subject matter of the invention perfectly clear without going further into the description of the operation of-the system in which said device is'intended to be used.

From the above description, it will be seen that I have devised a desk-stand in which the center of gravity is very low, due tothe location of the calling mechanism in the base of the structure and that many of the features herein disclosed are capable of use in other relations. It will beapparentalso that many alterations and modifications may 4 be made'in the structure herein disclosed without departing from the spirit and scope of my invention. For example, the arcuate frames 29 and 30 of the finger-hold mechanism may be combined in a single plate 29, as'shown in Figs. 15 and 16, which serves as the sole support for the modified fingerlevers 35, whose inner ends are not turned downward as in the case of levers 35, but lie in the same plane as ,the outward extending 1 ends. These levers are adapted to cooperate with the stop-pin 33, as in the case of the levers 35, but are'retained in their normal positions bythe coiled-springs 37". Likewise, other changes may be made. I, therefore, do not wish to be limited to the specific disclosure of the structure'and its use,but

aim to cover by the terms of the appended. .claims all reasonable modifications and adaptations.
