T 0 all whom it ma concern:
Be it known tliat I, CARL J. LANDIN, a citizen of the United States, residing at Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Telephone-Supports, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.
This invention relates to a support capable of sustaining a telephone or other object and has for its object to provide a novel device of this nature which is simple and ineozpensive to manufacture; which can be applied to any article of furniture, to a wall, or to a floor, and which will permit the telephone instrument or other article supported thereby to be moved up and down, in and out and laterally in either direction, or in any combination of these three directions, and which will auton'iatically hold the telephone instrument counterbalanced in any position in which it is left.
In order to give a proper understanding of my invention I have illustrated in the drawing a selected embodiment thereof which is in the nature of a telephone sunport and which will now be described, after which the novel features will be pointed out in the claims.
Figure 1 of the drawing is a side elevation showing a device embodyingmy invention; Fig. 2 is an enlarged section on the line wx, Fig. 1.
My improved device comprises a supporting standard, a supporting arm capable of supporting a telephone or other article but which is hereinafter referred to as a telephone-supporting arm inasmuch as the illustrated embodiment of the invention is a telephone support, means for connecting said arm to said standard at two different points, one of said connections being capable of moving horizontally or out-and-m, and the other being capable of moving vertically only, and a counterbalanemg memher acting on said telephone-supporting arm and adapted to counterbalance it in any position. In the preferred embodiment of my invention the connection between the telephone-supporting arm and the supporting standard is constituted by two parallel links pivoted to said arm and connected together, the lower end of one of wh1ch links is connected to the supporting standard so as to move out and in while the lower end of the other link is connected to said standard to move up and down. This combination of parts provides a device which ermits the telephone instrument sustaine on the telephone-supporting arm to be moved in and out, or up and down, or laterally, or in a direction which combines two or more of the above motions, thus making the device one which is useful in its action and by which the telephone can be supported in any desired posltion. In the illustrated embodiment of my invention the supportin standard is shown at l and it is sustaine in a bracket 2 that is fixed to a support 3 which may be a desk, wall or any other device. The standard 1 is mounted for turning movement in the bracket 2 and is made so that it can be readily removed from the bracket. As herein shown, the lower end of said standard is loosely received in a bore in the bracket and said standard is provided with a collar =1 which rests on the bracket and which holds it in vertical position.
The telephone-supporting member is shown in the form of an arm 15 to the end of which the telephone instrument 17 is secured in any suitable way, a clamp 16 being herein provided for that purpose, which clamp is swiveled to the end of the supporting member 15 by a universal joint connection 18. Pivoted to the supporting member 15 at 19 and 20 are two parallel links 11 and 12, said links being connected at their lower ends by a link 13. The link 11 is connected to the supporting standard 1 in such a way as to permit the lower end of said link to move up and down only relative to the standard, while the other link 12 is connected at its lower end to the standard in such a way as to permit said lower end to move out and in only. While any suitable connection between the links and the standard to permit the vertical movement of one link and the out and in movement of the other link may be provided, I have herein shown for this purpose two sleeves 7 and 8, the sleeve 7 being pivotally connected to the link 11 and slidable vertically on the supporting standard 1,-while the sleeve 8 is pivotally connected to the lower end of the link 12 and is mounted for lateral or out and in movement on the standard. This is herein provided for by forming the standard with the laterally-extending arm 5 on which the sleeve 8 is slidably mounted, and this armis shown as being formed by bending the upper end of the standard 1 laterally, as shown at (3 and then bending the end of the portion 6 backwardly on itself to present the laterally-extending arm 5.
The sleeve 7 has connected thereto a counterbalancing member herein shown in the form of a spring 21 which encircles the standard 1 and is connected at its upper end to said sleeve and at its lower end'to the standard, as shown at 22.
With the construction as thus above described, it is possible to move the telephone up or down in a substantially vertical plane or to move the telephone in or out horizontally or right and left, or to combine all of these motions and yet have the telephone automatically held and maintained in any position in which it is left. The full lines in Fig. 1 show the telephone raised and out of the way. The telephone may be brought down into convenient position for use in a substantially vertical direction by simply drawing downwardly on the telephone instrument, this operation swinging the supporting member 15 about the point 20 as a pivot and drawing the sleeve 7 upwardly on the telephone instrument, which operation.
results in causing the sleeve 8 to slide outwardly on the arm 5 at the same time that the sleeve 7 slides upwardly on the stand 1. The tension of the spring 21 counterbalances the weight of the telephone even when the parts are in the position shown by the dot and dash lines and will thus maintain the parts in this position. While the telephone is in the position shown by the dot and dash lines Fig. 1, it may be pushed back without raising it, this operation resulting in swinging the parallel links 11 and 12 into their vertical position and the sleeve 8 along the arm 5 into the full line position. Furthermore because of the fact that the standard 1 is swiveled in the bracket 2 it is possible to swing the telephone instrument into any position to the right or the left of that shown in the drawings.
The link 11 is shown as provided with a projection 25 which is adapted to engage the link 12 and thus limit the backward swinging movement of the telephone. Both links In this case the link 12 constim res 11 and 12 may be forked at their lower ends so that when they are moved forwardly into the dot and dash line view Fig. 1 the two arms of each link will straddle the part 6 of the stand. Said part 6 thus'constitutes a guide for the links and serves to maintain them in proper relative position.
In order to maintain the telephone in strument in proper balance when the receiver is removed from its hook and its weight is thus taken off from the telephonesupporting arm 15, I have provided a friction device associated with the link 11 and which applies suflicient frictional pressure to the supporting standard to counteract or offset the weight of the telephone receiver. In the illustrated embodiment of my invention this friction device is in the form of a spring-pressed friction block 23 which occupies a recess in the sleeve 7 and is yieldingly held against the standard 1. The spring 241- which acts on the block 23 will have such a tensionthat the friction of the block against the standard will be sufhcient to counteract the weight of the telephone receiver'so that when the telephone instrument is relieved of the weight of the receiver the position of the supporting arm .as maintained by the counterbalancing spring will remain unchanged.
It will be noted from the above that my device comprehends a telephone-supporting arm which is pivotally connected at two points with the supporting-standard, one of said connections having a capacity for movement out and in while the other of said connections has a capacity for vertical movement only, together with a counterbalancing means acting on said arm to hold the telephone in any position in which it may beplaced. Moreover, the device herein illustrated is very. simple in construction and can be inexpensively manufactured.
While I have illustrated a preferred embodiment of the invention I do not wish to be limited to the constructional details shown. It will also be obvious that the construction herein illustrated is capable of supporting other articles than telephones and while I have referred to the member 15 as a telephone-supporting member, I desire to state that I have used this term as illustrative and not as defining any limitation as to the use of the device. Hence I do not wish to be limited to the use of the device for supporting telephones.
Having fully described my invention,
tion with a supporting standard, of a telephone-supporting member, two parallel connected links both pivotall connected to said .telephone supporting member, a pivotal sliding connection between the lower end of for one link each link and the supporting standard, one of said connections permitting a vertical sliding movement and the other an in-andout movement, and counterbalancing means acting on one of said links.
