Nov. 19, 1929. 4 J. A. CAMERON MULTIPLE MANIPULATING SUSPENSION ARM Filed Feb. 1, 1926 w: nmss Patented Nov. 19, 1929 JAMES 'A. CAMERON, OF BUFFALO, NEW YORK MULTIPLE MANIPULATING- SUSPENSION ARM Application filed February '1, 1926. Serial No. 85,319.
My invention relates to improvements in multiple manipulating supports in which the standard American desk telephone is at-.
tached to a multiple extension support which may be attached in a'greater variety of location'and permit desired use positioning and the principal objects 1 of my improvements are first, to provide a convenient upright rest position for the telephone clear of the desk G and means for easily bringing the telephone into use position over the desk and clear of the ordinary desk work on hand, and various positioning and adjusting means for adapting the device to general use demands; second, to provide means for automatically making or breaking the electrical circuits when the telephone is moved into use or rest position respectively, and adjustable means for holding the telephone'receiver when in rest or use position.
I- attain these objects by. the mechanism illustrated in the accompanying drawings, in whicht Figure 1 is a side view of the entire device, comprising the multiple support and showing the telephone in upright or rest position; Fig. 2, a side view showing the telephone partially inverted and in use position, Fig. 3, a plan view of the mechanism as shown in the preceding figure; Fig.4, an inverted.
plan view of the self balancing frame; Fig.
5, an end view of the friction cam, and being apart of the mechanism ofthe tilting frame; Fig. 6, a side view of the cam; Fig. 7, a side sectional view of the cam and elongated slots for guiding the friction-shoe which contacts on the surface of the cam; Fig. 8, is a side view of theelectrical telephone circuits, the weighted make and break circuit controlling means and the bell-bo x;rFig.;9,, a side view of a friction retarding clamp used on the extension members of the support; Fig. 10, is a side view of the telephone receiver and adjustable clamp on'the receiver holding'rod.
Similar numerals represent similar parts in the various drawings.
The base 1, resting on the desk, the rod 2 threaded on the lowerend and with a-hole 7 near the upper end thereof, the grip-nut 3 the set-screw 4 for setting the rod 2 in the base 1, the set-collar 5 set on the rod 2 over the base 1 by the set-screw 6, constitutes the support upon which the entire device is swung. Inserting a pin or rod in the hole 7 and turning to draw the grip-nut 3 and base 1 together will clamp the device firmly on the desk when the set-screw 4 may be tightcued on the rod 2, and the'collar may then be adjusted on the rod 2 to the'desired raised position; p
The lazy-tong 8 has-a swivel 9 adaptedto befrictionallyretardedor bound on the rod 2 by the set-screw 10,
be adjusted in various raised locations on the swivelmember 9, a forward swivel 12 with a-pin 13 set therein and a friction retarding clamp 14, more clearly shown in Figure 9 and adapted to adjust'ably bind moving members of the lazy-tong, constitutes one extension unit of the support.
The other extension unit of the support lazy-tong15 is composed-of a rear swivel 16 pivoted onthe pin 13' and may be frictionally retarded or boundthereon by the set-screw 17, a post 18 adapted to various raised ad justments on the swivel member 16, a forward swivel 19 with a pin 20 set therein, a friction retarding clamp 21, more clearly shown in Figure 9, a roller 22 on the upper end of the post 18, a control rod 23 having one end pivoted to one of the moving parts of said lazy-tong and the extended portion resting on the roller 22 and beyond said roller provided with a clamp 24. The forward end of clamp 24 slopes down to a projection 25 and back into a rest-slot 26 and ends in a stop 27 with a set-screw 28 for setting the clamp 24 firmly on the rod 23. The clamp 24-serves as a limit gauge on the extension movement of lazy-tong 15 and holding same in use position, and the projection 25 acts as a slight resistance to folding said lazy-tong thus holding the telephone more firmly in use position.
The rear end otthe U shaped supporting arm 29'swivels on the pin 20'and is adapted to be frictionally retarded in movement or bound'on said pin by the set-screw 30.
' A tilting t'rame 31 ispivoted 32 in the outer end of the supporting arm '29 and is a post 11 which may formed like a U shaped plate with the sides 'bent downward and provided with clips 33 on the forward end and an adjustable clip 3& and set-screw 35 fastened on the rear end. Said clips are adapted to clamp the telephone base 36 firmly to the upper surface of said tilting-frame. A pair of spaced elongated slots 37 37 are located within the U V shaped supporting arm 29 andhaving one end 7 and the adjusting-screw for the purpose of adjustingsaid cam. The
attached to the rear thereof and the other ends to the pivotal pin 32. The forward end of the tilting-frame 31has a lug 38 bent downward and an U shaped and the semi-circular shaped sides extendlng downward from the base have flanges 41 bent inwardly at right angles and have radatin dents 42 slo in 1n-' outer ends of the friction shoe 4.5 are inserted through the slots in guides 37 37 and have friction surfaces &6 machined thereon conforming to'the circular inner surfaces of the flanges 41. A tension-spring 47is connected'to thepin a5 and attached to the rear of'the U shaped supporting arm 29. Turning'theset-screw 39 to move to the spring 17 as the telephone nears the horizontal and partially inverted or use position. These adjustments will be'made to arrive at the desired set given to the telephone use position. The tension spring L7 should be regulated to cause the telephone toreturn automatically to rest position when the outer end of the telephone is given a slight toss upward off use position, and as the telephone nears its upright or rest position the ifrictionshoe a5 will engage the dents 12 42 on the rear of the'cam 40 and greater tension pull slow up the return motion and the shockabsorber 63 will cushion the final rest movement.
. frame.
' The rear end of the tilting-frame 31 extends beyond. the telephone base 36 and is provided with a pair of adjusting standards 50 50 punched and formed upward in said The legs of a U shaped clamping arm 51 are "pivotally pinned 52in the ex tended portion of the frame 31 and slide be- 50 and are provided with a bolt and set-nut 53 adapted to clamp the 7 standards 5O 50 within the head of said bolt and the nut 53 against the legs of said arm 51, and a tubular spacer 54 through which said bolt is inserted aids in firmly holding said legs against said standards; A right bend plate 55 is formed 51 and a pivotal-pin 56 over the top 01. arm
' is provided with snap adjusting screw 39 pivot-' ally set therein. The cam member 40 is bent f thereof the rear of the cam 40 closer to the pivotal-pin 32 will give passes through the lower end of the resilient receiver holding rod 57 and the arm 51 and plate 55. The lock-bar 58 is pivoted 59 on the top of the upper bend of said plate 55 and held projecting over the rod 57 by the tension-spring 62 connecting the rear end of the bar 58 and the pin 52 and provides a position lock for the rod 57 resting on the right lower bend of plate 55.
The cylinder 63 issuitably located on the supporting arm 29 .and'provided with a piston 64 fitting therein and with a push-spring 65 placed between der and piston and is adapted to cushion the movement ofthe tilting frame 31 when about dogs 60 61 normally V the bottom of said cylinto seat inits normal rest position and acting as a pneumatic shock-absorber.
The ball- 66 is integral with or may be set on the outer end of rod 57 and is gripped between one end of two clamping-members 67 67 the other'end of which grips the. end of the telephone receiver 68 and said members and receiver are held in desired position on said ball by the set-screw 69.
The circuit control means or switch hook 7 O is weighted'71 on one end and pivoted'7 2 on the other end within the telephone post and provided with a bell-crank 'or projection 73 pivotally connected with a link 74 leading to and pivoted on one end ofa' contact spring 75 adapted toenga'ge with the contact 76, electrically transmitter 7 9 and receiver 68 as in standard telephone circuit practice, when the telephone is approximately supported horizontally or partially inverted and in use position, and to engage the contact 80, electrically 81 connected to the bell-box 82 as in standard practice, in upright or rest position whenthe weight 71 forces the circuit controlling means 70 downward and breaks the transmitter and receiver circuits, as represented by the position'indicated in the dotted line of Figure 8. v The inner end of the tubular sleeve is pivoted "91 to the desired moving part of thelaZy-tong 15 and the other end'has inserted therein therod 92 pivoted 93 in the outer end of the tilting-frame 31. The rod 92 may be set in the sleeve 90 by the clamp and set-screw 94 in desired relation. The moving part of the lazy-tong 15 which may be located farther or nearer the post 18 to which the rear end of the sleeve 90 is pivoted will control the less or greater movement respectivelv transmitted to the tilting frame 31 in comparison with the extension travel of said lazy-tong. r lVhendesiring to use the telephone, grasp the post 85' and. draw toward you. As the lazy-tong 15 extends it will be noted that the member to which the sleeve 90 is pivoted increases its @distance fromtl e pivotal pin 32 causing the rod 92 pivoted on the pin 93 7 8 connected to the to draw the tilting-frame 31 downward until the telephone is in the desired use position, which position when once determined the user may proceed to tighten the set-screw 10, and clamp 14, and the set-screw 28 of clamp 24 adjusted so the roller 22 rests in the slot 26. The receiver holding rod 57 may be adjusted to permit the receiver to be located in suitable position for the ear and the setscrew 53 tightened and also the set-screw 69. If it is desired to use the receiver at the right ear, lift the lower end of rod 57 past the dog 60 and swing the receiver over to the right side past the dog 61 which serves tohold the receiver in required position when the telephone is returned to rest position or brought into use position. Vhen through telephoning give the transmitter end of the telephone a slight toss upward and the lazy tong 15 will fold backwardand the telephone arrive at rest position and the weight 71 will fall and automatically break the talking circuits and make the bell-circuit;
If desired, the sleeve 90 and rod 92 may be removed, and manually'tilting the telephone into use or rest position resorted to. The set-screw 21 may be tightened should sufiicient clearance be found for ordinary desk work when the telephone is merely returned to upright rest position and without extending and folding the lazy-tong every time the telephone is used. The supportingarm 29 may be swiveled into suitable angle and the set-screw 30 tightened, the multiple swivels permitting various adjustments of telephone positioning.
