UNITED STATES PATENT OFFICE.
ERNEST S. MoLARN, OF NEW YORK, N. Y., ASSIGNOR TO WESTERN ELECTRIC COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.
To all whom it may concern:
Be it known that I, ERNEST S. MOLARN, citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Transmitter-Brackets, of which the following is a full, clear, concise, and exact description.
My invention relates to pivotally mounting telephone transmitters, and resides more particularly in the bracket, which is mounted upon the front of the box of the subscribers set, and adapted to receive the arm or lug provided upon the case or cup which carries the transmitter.
The prior art is exemplified in the following patents relating to pivotally mounting telephone transmitters: No. 67 5,087 of May 28th, 1901, to Graven; No. 729,18t of May 26th, 1903, to Kaisling; and No. 831,855 of September 25th, 1906, to Guttman.
My invention will be more readily understood by reference to the accompanying drawing, in which Figure 1 is a side elevation showing a transmitter mounted upon my bracket, the escutcheon plate which supports the bracket being in section; Fig. 2 is a view of the bracket taken on section line 22 of Fig. 1;
Fig. 3 isa perspective view of the bracket detached; and Fig. 4 is a detailed sectional view taken on line l of Fig. 2, and showing the opening through the arm which accommodates the cord or connections leading to the transmitter.
Like parts are indicated by the same characters of reference in the different figures.
The transmitter case 1 is of usual construction, being provided with the rearwardly projecting arm or lug 2. The front 3 of the box is cut away, as shown, and the bracket 4 is secured to the escutcheon plate 5 by means of screws 6, 7. This escutcheon plate and the bracket are preferably stamped out of sheet metal. The clamping screw 8 passes through the rear portion of the plates or sides of the bracket and when tightened serves to clamp the arm of the transmitter between the said sides to hold the same in frictional engagement, thus permitting the pivotal movement of the arm within the bracket, but at the same time preventing the' removal of the said arm.
It will be observed that bosses are pro- Specification of Letters Patent.
Application filed June 10, 1908.
Patented Dec. 8, 1908.
Serial No. 437,655.
vided upon the sides .of the bracket which form the frictional and pivotal engagement with the arm of the transmitter. The larger bosses 9, 9 serve to keep the rearward edges of the arm free from the clamping sides or ears of the bracket, and thereby prevent any cutting action in the movement of the said arm, and this frictional engagement is such that the transmitter when either raised or lowered will be held in such position until force is again applied to change the position thereof. Small bosses 10, 10 are provided in the larger bosses, and these smaller bosses extending into the counterbored ends 11 of the opening of the arm 2 serve to keep the arm centered, while permitting the pivotal movement thereof.
As shown in Fig. l, a channel 12 is provided in the arm 2. The connection with the transmitter is inserted through this channel over the pin or stud 13. The edges of the bracket are turned over to give the sides thereof the required stiffness.
In order to remove the transmitter from the bracket, it is only necessary to loosen the screw 8. The transmitter being then removed, another transmitter may be snapped back in place, and the screw will then be again tightened. It will be observed that the screw and other parts of the mounting are so arranged as to be out of the way of the cord.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
'1. The combination with the transmitter arm, of the bracket, the box of the subscribers set on which the bracket is mounted, said bracket consisting of sheet-metal provided with the larger and smaller bosses, the arm being supported and pivoted in said bracket between the bosses, and the clamping screw for adjusting the pressure of the bosses upon said arm.
2. An arm in combination with a bracket of spring sheet-metal provided with clamping sides or ears in which the arm is pivotally mounted, means for adjusting the engagement or clamping action of the bracket to permit of the insertion and removal of the arm, said arm being provided with counter-bored openings or sockets, and bosses on the said ears fitting into said open mgs.
3. The bracket of sheet-metal, the escutcheon plate on which the bracket is mounted, in combination with a transmitter arm pivotally mounted in said bracket, the pivotal mounting comprising the larger bosses, and the smaller bosses, the clamping-screw 8 for adjusting the clamping action of the bracket upon said arm, the transmitter carried on said arm, the arm being provided with a channel, and the connection with the transmitter had through said channel, substantially as and for the purpose specified.
4. In a transmitter bracket, the combination with an escutcheon plate having an opening therein through which the arm of the transmitter passes, a U-shaped bracket secured thereto, said bracket being provided with bosses forming a pivotal frictional mounting for said arm, means for adjusting the frictional engagement of said bosses upon said arm, whereby said arm is frictionally held in any position in which it may be set.
The combination with the transmitter arm, of the escutcheon plate secured to the front of the box of the subscribers set, a Ushaped bracket secured to the back of said plate and extending through an opening in said box, large and small bosses stamped in the sides or ears of said bracket, the smaller bosses serving to centrally pivot the transmitter arm, the larger bosses being in adustable frictional engagement with the arm, and a channel provided in said arm, substantially as and for the purpose specified.
In witness whereof, I, hereunto subscribe my name this 3rd day of June A. D., 1908.
ERNEST S. McLARN.
