- Surrounding the sleeve 76 is a sleeve 82 closely adjacent the disc 80. At its outer end the sleeve 82 has an end wall with a hole into which the end of the screw 74 extends.
- the end of the screw is enlarged so that the sleeve 82 cannot move endwise with respect to the screw.
- a coil spring 84 is located between the sleeves '76 and 82, one end abutting against the disc 80 and the other end abutting against the end wall of the sleeve 82.
- the screw is provided r with a knurled head 86 by means of which it may be turned.
- the screw 74 has threaded engagement with the block 66 at the right of the slot 72, but does not have threaded engagement with the remainder of the block nor with the sleeve 76.
- the screw 74 is turned in one direction the two portions of the block 66 at opposite sides of the slot '72 are forced toward each other so as to grip the pin 70 and prevent it from turning.
- the arm 64 can be clamped in adjusted positions.
- the screw is turned in the opposite direction the pin 70 and the arm 64 are released.
- the disc 80 is provided at its periphery with a series of notches 88 which have successively increasing depths and each of which is of such width as to receive the reduced end portion of the arm 64. Eight notches are shown but the number may be varied.
- the arm 64 may be held in an elevated adjusted position solely by the clamping action on the trunnion pin 79. However, when the arm 64 is in a lower adjusted position, the reduced end portion thereof is entered in one of the notches 88 so as to be positively supported.
- the pin 70 and the disc 80 are released, the arm 64 may be moved temporarily to an elevated position and the disc 80 may be turned to bring any selected notch 88 into register with the reduced end portion of the arm.
- the spring 84 provides frictional resistance to prevent free turning of the disc 80.
- the arm 64 may be lowered into the selected notch, and then the screw 74 is turned to clamp the pin 70 and the arm 64. Thus the arm 64 may be positively supported in any one of eight different positions.
- the holder 26 is preferably carried by a plate 90 which is so connected with the arm 64 that it may be rotatably adjusted with respect thereto.
- a disc 92 havin a hollow hub 94 which is interiorly threaded for engagement with a threaded end portion of the arm 64.
- a second disc 96 is provided which normally has face to face engagement with the disc 92, the said disc 96 being directly connected with the plate 90.
- the disc 96 is provided with an integral stud 98 which extends through an aperture in the disc 92 and into the hollow hub 94 thereof.
- a coil com may be connected with the plate in any one of a plurality of different angular positions with respect to an axis perpendicular to the plate.
- the stud 146 has a polygonal shape at 149, which shape is preferably a hexagon.
- the opposite parallel walls of the stud at 149 are so spaced as to be adapted to enter between and approximately fit the side walls of the slot 142 as shown in Fig. 15.
- the head 148 of the stud or retainer is of such size as to be adapted to pass through the opening 144 in the plate 140.
- the upper portion of the plate 140 having the opening 144 therein is somewhat thinner than the lower portion of the said plate.
- the thickness of the upper portion of the plate is somewhat less than the distance between the holder wall 116 and the adjacent face of the head 148. This facilitates entry of the stud or retainer so that the head 148 thereof will freely pass behind the face of the plate when the holder and stud are moved downward.
- the lower portion of the plate 140 is thicker, its thickness being approximately the same as the distance between the holder wall 116 and the adjacent face of the head 148.
- the thickness of the plate may be made increasingly greater at steps v, 151 and 152 as shown in Fig. 15.
- the holder 26 can be connected with the plate 140 in a plurality of positions which are angularly different, the several optional positions being at 60 from each other.
- the described construction not only enables the holder to be attached to the plate at a variety of angularly different positions but also enables the holder to be readily detached from the plate 140 by manually moving it parallelly with the said plate. in order to detach the holder it is merely necessary to move it along the plate and to then raise it so that the head 148 can be moved through the opening 144.
- Fig. 14 shows the holder detached from the plate.
- Fig. 18 shows a construction similar to that shown in Figs. 13 to 17 but different in detail.
- the stud 146 there is provided a stud 153 having a head 154 similar to the head 143. Between the wall 116 and the head 154 the stud 153 is threaded and a nut 155 is engaged with the threaded portion of the stud. The thickness of the nut 155 is slightly less than the distance between the wall 116 and the head 154.
- the exterior shape of the nut 155 is or may be the same as the exterior shape of the stud 146 at 149.
- the construction shown in Fig. 18 serves the same purpose as the construction shown in Figs. 15 to 17.
- the holder 26 can be put in place in any one of several angularly different positions and the holder can be readily removed and replaced as required.
- the thickness of the nut 155 is only a few thousandths of an inch less than the distance between the wall 116 and the head 154 and the nut 155 is rotatable with respect to the stud through only a small fraction of a turn.
- the holder 26 With the holder 26 in place on the plate 140, it can be rotated through the aforesaid small fraction of a turn, preferably less than 60.
- the holder When the holder is rotated in one direction, one face of the nut is brought into engagement with the head 154 as shown in Fig. 18, the holder being thus frictionally locked.
- the opposite face of the nut is brought into engagement with the wall 116, the holder being again frictionally locked.
- the holder 26 can be rotated and frictionally locked at intermediate positions between the positions determined by the engagement of the opposite sides of the nut 155 with the walls of the slot 142.
- Fig. 18 shows a construction similar to that illus-- trated in Fig. 18 but differing in detail.
- a stud 153 which is or may be the same as the stud shown in Fig. 18, the said stud having a similar head 154.
- a nut 156 which is similar to the nut 155 but somewhat thinner.
- sides of the nut 156 are two oppositely disposed dished spring washers 157, 157.
- the angle of the washers is considerably exaggerated in the drawing for clarity of illustration. In practice the angle is very small and the nut 156 has a thickness considerably greater than that shown.
- the action is the same as that described in connection with Fig. 18 except that the washers frictionally resist rotative movement of the nut and thus resist rotative movement of the holder.
- FIGs. 19 to 24 show another alternative construction for connecting the holder with its supporting plate and for enabling the holder to be angularly adjusted.
- a supporting plate 158 is provided generally similar in function to the supporting plate 90.
- an arm 160 is provided which is generally similar to the arm 64 but which is rigidly connected with the plate 158 instead of being connected therewith by means of a mechanism such as that shown in Figs. 7 and 8.
- a guide extending parallelly with the plate 158 Secured to the plate 158 are two oppositely positioned gibs 162, 162 which constitute a guide extending parallelly with the plate 158.
- the said gibs engage with and support a slide or retainer 164 connected with the holder 26.
- the slide or retainer 164 has lateral projections 166, 166 at the top which engage the gibs to limit downward movement of the slide. lnasmuch as the holder 26 is secured to the slide 164, the holder is thus supported on the plate 158.
- the holder 26 can be detached from the plate 158 by merely moving the said holder and the slide or retainer upward parallelly with the plate so that the slide is disengaged from the gibs or guide.
- Fig. 23 shows the holder and retainer detached from the plate.
- the holder 26 is connected with the slide or retainer 164 for angular adjustment with respect thereto.
- a washer 168 is secured to the rear wall 116 of the holder, this washer engaging at its rear with the front face of the slide 164.
- a rivet 171) extends through suitable apertures in the wall 116, in the washer 168 and in the slide 164. It will be seen that the holder 26 and the washer 168 can be angularly adjusted with respect to the slide 164 about the axis of the rivet 170.
- a spring washer 172 is interposed between the wall 116 and one head of the rivet 170, this spring washer providing frictional engagement between the washer 168 and the slide 164.
- the washer 168 has an annular series of detents 174 which are adapted to enter a similar series of depressions 176, 176 in the front of the slide 164. With the detents entered in the depressions the washer 168 and the holder 26 are yieldably held in any one of a plurality of angularly different positions.

ACCESSORY FOR USE WITH TELEPHONES Filed May 25, 1949 3 Sheets-Sheet 3 INVENTOR SANFORD C. CHESICK By ,1 gjrv wav TORNEY Vertically movable on the post 14 is a slide 34 which is preferably in the form of a sleeve surrounding and fitting the post. Carried by the slide or sleeve 34 is a horizontally extending arm 36 which extends over the button 32 as shown in Fig. 1. Preferably the sleeve 34 is guided for vertical movement on the post 14, relative rotative movement being prevented by a pin 38 extending into a vertical spline 40, as shown in Fig. 3. Thus the sleeve 34 is free for vertical movement, but relative rotative movement is prevented.
Preferably the arm 36 is rotatively connected with the sleeve 34, this being desirable in order that the telephone base may be placed in different positions on the platform 10. As shown, the arm has an aperture through which the sleeve extends, the sleeve having an external thread 42 and the aperture in the arm having a mating internal thread. The mating threads permit the arm to be turned relatively to the sleeve.
For vertically moving the sleeve 34 and the arm 36 there is provided at least one manually movable eccentric and preferably there are two such eccentrics. As shown, the post 14 is flattened at opposite sides and a rotatable shaft 44 extends through a horizontal bearing aperture in the post. Secured to the shaft 44 are two similar eccentrics 46, 46 which engage the opposite fiat faces of the post. Connected with the shaft 44 and the eccentrics 46, 46 is a manually operable lever 48 for turning the said shaft and eccentrics. When the lever 48 is in the upper position, as shown in Figs. 1, 2 and 3, the eccentrics are in the positions to permit the sleeve 34 and the arm 36 to move to their lowermost positions. When the lever 48 is moved to its lowermost position, the eccentrics 46, 46 move the sleeve 34 and the arm 36 to their uppermost positions. Inasmuch as there are two eccentrics, pressure is applied to the sleeve 34 at both sides of the post. A pin 50 on the post 14 limits the movement of the lever 48 so that the sleeve 34 and the arm 36 are either in their lowermost positions or in their uppermost positions. Preferably the lever 48 has notches as shown to receive the pin 50 A spring is preferably provided for biasing the sleeve 34 and the arm 36 in the downward direction and as shown there is a coil spring 52 which surrounds the upper portion of the post 14. The lower end of the spring 52 abuts against the top of the sleeve 34 and the upper end of the spring abuts against a sleeve 54 carried by the upper portion of the post.
As has been stated, the arm 36 engages the button 32 on the base of the telephone. When the lever 48 is moved to its upper position, as shown, the arm 36 is moved downward by gravity and by the spring 52 so as to depress the button 32 to its lower open-circuit position. When the lever 48 is moved to its lower position, the sleeve 34 and the arm 36 are moved upward thus permitting the button 32 to assume its upper closedcircuit position. Thus the user of the accessory can close or open the telephone circuit at will by merely moving the lever 48.
The base of the telephone has the usual upward projections 56, 56 at opposite sides of the button 32 and preferably the arm 36 is provided with two pairs of rollers 58, 58 which are so positioned that the rollers of the said pairs are at opposite sides of the said projections 56, 56. The rollers are preferably formed at least in part of rubber or equivalent material. The telephone base 30 is accurately positioned on the platform so that the projections 56, 56 thereof are between the pairs of rollers 58, 58. The rollers constitute anti-friction means which permit the arm 36 to freely move upward or downward with respect to the base and inasmuch as the said rollers are formed at least in part of rubber or equivalent material, there is no possibility of scratching the said projections on the base.
The telephone base shown in Figs. 1 and 2 is that of a standard telephone. Certain other telephones, as for instance those for inter-office use, have the button 32 at a slightly different elevation. In order to properly cooperate with buttons at different elevations, the arm 36 is vertically adjustable with respect to the sleeve 34. The before-mentioned threaded connection between the arm and the sleeve is utilized for vertical adjustment. The arm 36 can be turned in either direction on the threads and can be thus raised or lowered. The full lines in Fig. 3 show the arm in a lower position and the dotted lines show it in an upper position. For locking the arm 36 in adjusted position there is provided a threaded sleeve all) 60 which serves as a lock nut. The sleeve 60 is in-- ternally threaded to engage the thread on the sleeve 34 and the lower end of the sleeve 60 abuts against the arm 36. The sleeve 60 is of such length that it encloses the spring 52, the upper end of the sleeve fitting the sleeve 54. The sleeve 69 is preferably exteriorly knurled so that it may be readily turned into or out of locking engagement with the arm 36.
The upper portion of the post 14 has a central cylindrical aperture therein and a vertical rod 62 accurately fits this aperture. The rod 62 is rotatable in the aperture and its lower end is seated against the bottom of the aperture. A laterally extending arm 64 is provided which is adjustably connected with the upper portion of the rod 62.
For connecting the arm 64 with the rod 62 there is provided a block 66 apertured at the bottom to receive the upper end of the rod. The block is preferably pinned to the rod. The block 66 has a central recess at the top, this recess providing two cars 68, 68 at the sides. An interrupted horizontal bearing aperture is formed in the cars 68, 63, this bearing aperture receiving and fitting a horizontal trunnion pin 70 which is pivotally movable in the aperture. The corresponding end portion of the arm 64 is reduced in diameter and extends through a central aperture in the trunnion pin 76. The arm 64 is permanently secured in its position in the pin. It will be seen that the arm 64 can be moved in a vertical plane about the axis of the pin 70.
The block 66 has a diagonal slot as indicated at 72, this slot extending to the aperture for the pin 70. A screw 74 extends through a horizontal hole in the block, the said hole intersecting the slot 72. Positioned at the right side of the block 66 is a sleeve 76 surrounding the screw and having a flange 78 adjacent the block. A disc 80 is rotatably mounted on the sleeve 76 adjacent the flange 78. Surrounding the sleeve 76 is a sleeve 82 closely adjacent the disc 80. At its outer end the sleeve 82 has an end wall with a hole into which the end of the screw 74 extends. The end of the screw is enlarged so that the sleeve 82 cannot move endwise with respect to the screw. A coil spring 84 is located between the sleeves '76 and 82, one end abutting against the disc 80 and the other end abutting against the end wall of the sleeve 82. At its opposite end the screw is provided r with a knurled head 86 by means of which it may be turned.
The screw 74 has threaded engagement with the block 66 at the right of the slot 72, but does not have threaded engagement with the remainder of the block nor with the sleeve 76. When the screw 74 is turned in one direction the two portions of the block 66 at opposite sides of the slot '72 are forced toward each other so as to grip the pin 70 and prevent it from turning. Thus the arm 64 can be clamped in adjusted positions. When the screw is turned in the opposite direction the pin 70 and the arm 64 are released.
The disc 80 is provided at its periphery with a series of notches 88 which have successively increasing depths and each of which is of such width as to receive the reduced end portion of the arm 64. Eight notches are shown but the number may be varied. The arm 64 may be held in an elevated adjusted position solely by the clamping action on the trunnion pin 79. However, when the arm 64 is in a lower adjusted position, the reduced end portion thereof is entered in one of the notches 88 so as to be positively supported. When the pin 70 and the disc 80 are released, the arm 64 may be moved temporarily to an elevated position and the disc 80 may be turned to bring any selected notch 88 into register with the reduced end portion of the arm. The spring 84 provides frictional resistance to prevent free turning of the disc 80. The arm 64 may be lowered into the selected notch, and then the screw 74 is turned to clamp the pin 70 and the arm 64. Thus the arm 64 may be positively supported in any one of eight different positions.
The holder 26 is preferably carried by a plate 90 which is so connected with the arm 64 that it may be rotatably adjusted with respect thereto. As shown in Figs. 7 and 8, there is provided a disc 92 havin a hollow hub 94 which is interiorly threaded for engagement with a threaded end portion of the arm 64. A second disc 96 is provided which normally has face to face engagement with the disc 92, the said disc 96 being directly connected with the plate 90. The disc 96 is provided with an integral stud 98 which extends through an aperture in the disc 92 and into the hollow hub 94 thereof. A coil commay be connected with the plate in any one of a plurality of different angular positions with respect to an axis perpendicular to the plate. Between the rear wall 116 and the head 143 the stud 146 has a polygonal shape at 149, which shape is preferably a hexagon. The opposite parallel walls of the stud at 149 are so spaced as to be adapted to enter between and approximately fit the side walls of the slot 142 as shown in Fig. 15. The head 148 of the stud or retainer is of such size as to be adapted to pass through the opening 144 in the plate 140.
Preferably the upper portion of the plate 140 having the opening 144 therein is somewhat thinner than the lower portion of the said plate. The thickness of the upper portion of the plate is somewhat less than the distance between the holder wall 116 and the adjacent face of the head 148. This facilitates entry of the stud or retainer so that the head 148 thereof will freely pass behind the face of the plate when the holder and stud are moved downward. 'lhe lower portion of the plate 140 is thicker, its thickness being approximately the same as the distance between the holder wall 116 and the adjacent face of the head 148. Thus, when the holder and stud are in their normal lower position, the holder is firmly connected with the plate without any lost motion. The thickness of the plate may be made increasingly greater at steps v, 151 and 152 as shown in Fig. 15.
When the shape at 149 is hexagonal the holder 26 can be connected with the plate 140 in a plurality of positions which are angularly different, the several optional positions being at 60 from each other. The described construction not only enables the holder to be attached to the plate at a variety of angularly different positions but also enables the holder to be readily detached from the plate 140 by manually moving it parallelly with the said plate. in order to detach the holder it is merely necessary to move it along the plate and to then raise it so that the head 148 can be moved through the opening 144. Fig. 14 shows the holder detached from the plate.
Fig. 18 shows a construction similar to that shown in Figs. 13 to 17 but different in detail. In lieu of the stud 146 there is provided a stud 153 having a head 154 similar to the head 143. Between the wall 116 and the head 154 the stud 153 is threaded and a nut 155 is engaged with the threaded portion of the stud. The thickness of the nut 155 is slightly less than the distance between the wall 116 and the head 154. The exterior shape of the nut 155 is or may be the same as the exterior shape of the stud 146 at 149. The construction shown in Fig. 18 serves the same purpose as the construction shown in Figs. 15 to 17. The holder 26 can be put in place in any one of several angularly different positions and the holder can be readily removed and replaced as required.
The thickness of the nut 155 is only a few thousandths of an inch less than the distance between the wall 116 and the head 154 and the nut 155 is rotatable with respect to the stud through only a small fraction of a turn. With the holder 26 in place on the plate 140, it can be rotated through the aforesaid small fraction of a turn, preferably less than 60. When the holder is rotated in one direction, one face of the nut is brought into engagement with the head 154 as shown in Fig. 18, the holder being thus frictionally locked. When the holder is rotated in the other direction, the opposite face of the nut is brought into engagement with the wall 116, the holder being again frictionally locked. With the construction shown in Fig.
18 the holder 26 can be rotated and frictionally locked at intermediate positions between the positions determined by the engagement of the opposite sides of the nut 155 with the walls of the slot 142.
Fig. 18 shows a construction similar to that illus-- trated in Fig. 18 but differing in detail. There is a stud 153 which is or may be the same as the stud shown in Fig. 18, the said stud having a similar head 154. in lieu of the nut 155 there is provided a nut 156 which is similar to the nut 155 but somewhat thinner. sides of the nut 156 are two oppositely disposed dished spring washers 157, 157. The angle of the washers is considerably exaggerated in the drawing for clarity of illustration. In practice the angle is very small and the nut 156 has a thickness considerably greater than that shown. The action is the same as that described in connection with Fig. 18 except that the washers frictionally resist rotative movement of the nut and thus resist rotative movement of the holder. When the nut 156 moves toward the head 154 one washer is flattened and,
At oppositewhen the nut moves toward the wall 116 the other Washer is flattened.
Figs. 19 to 24 show another alternative construction for connecting the holder with its supporting plate and for enabling the holder to be angularly adjusted. A supporting plate 158 is provided generally similar in function to the supporting plate 90. in lieu of the arm 64, an arm 160 is provided which is generally similar to the arm 64 but which is rigidly connected with the plate 158 instead of being connected therewith by means of a mechanism such as that shown in Figs. 7 and 8.
Secured to the plate 158 are two oppositely positioned gibs 162, 162 which constitute a guide extending parallelly with the plate 158. The said gibs engage with and support a slide or retainer 164 connected with the holder 26. The slide or retainer 164 has lateral projections 166, 166 at the top which engage the gibs to limit downward movement of the slide. lnasmuch as the holder 26 is secured to the slide 164, the holder is thus supported on the plate 158. it will be seen that the holder 26 can be detached from the plate 158 by merely moving the said holder and the slide or retainer upward parallelly with the plate so that the slide is disengaged from the gibs or guide. Fig. 23 shows the holder and retainer detached from the plate.
Preferably the holder 26 is connected with the slide or retainer 164 for angular adjustment with respect thereto. As shown, a washer 168 is secured to the rear wall 116 of the holder, this washer engaging at its rear with the front face of the slide 164. A rivet 171) extends through suitable apertures in the wall 116, in the washer 168 and in the slide 164. It will be seen that the holder 26 and the washer 168 can be angularly adjusted with respect to the slide 164 about the axis of the rivet 170. A spring washer 172 is interposed between the wall 116 and one head of the rivet 170, this spring washer providing frictional engagement between the washer 168 and the slide 164. Preferably the washer 168 has an annular series of detents 174 which are adapted to enter a similar series of depressions 176, 176 in the front of the slide 164. With the detents entered in the depressions the washer 168 and the holder 26 are yieldably held in any one of a plurality of angularly different positions.
