l PETER C. BURNS, OF' CHICAGO, ILLINOIS.
TELEPHONE-RECEIVER;
SPECIFICATION fornirgpart of Letters Patent NO. 605,594, dated J une 14, 1898. 2 I Application ledNovember 20, 1897. Serial No. 659,248. (No model.)-
To all whom t concern:`
Be it known that I, PETE'E C. BURNS, a citizen of the United States, residing at Chicago,
in the county of Cook and State of Illinois,
have invented a certain new and useful Improvement in Telephone-Receivers, of which the following is'a specication.
My invention has forits object the production of means, simple and-effective in action, by which the distance or space between the end of thepermanent magnet or the pole of such magnet and thediaphragm may be adjusted accurately and readily and when adjusted securely held in the adjusted position.
It also has for its object the ready removal of the casing of the receiver1 to give access to the permanent magnet, wires, and other electrical agencies inclosed therein.
Reference may now be had to the accompanying drawings, in which- Figurel is a central longitudinal section completely through the telephone-receiver. Fig. 2 is a like View showing the parts detached and ready to be assembled. Fig. 3 is a section on the correspondinglynumbered line in Fig. l seen in the direction of the arrow, the casing being removed.
In carrying out my invention I provide a cup-shaped member which is screw-threaded to receive Jthe cap of the receiver., which holds the diaphragm. When the cap holding the diaphragm is screwed upon the cup -shaped member, they together form a chamber within which the end ofthe permanent magnet of the receiver or the pole of the receiver is positioned. The cup-shaped member, with the diaphragm-cap secured thereto, is held upon a collar fixed on the end portion of the permanent magnet and connected by screwthreads therewith. The collar holds a disk having at intervals stop-screws which, passing through the disk, will impinge and bear against the rim of the cup-shaped member. The cup-shaped member, with the cap thereon and the diaphragm contained therein, is adapted for movement along the permanent magnet by virtue of the screw-threaded lconnection between-the collar and the cup-shaped member, thus drawing the diaphragm toward or awayfrom the end or pole of the permanent magnet and adjusting the same in proper end. thereof. JThe diaphragm-cap is designated at B,'holding`thereon the diaphragm B2. The cup-shaped member is designated at D and may be termed the adjusting-ring. A collarE, screw-threaded at a and having a shank E2, is secured by said shank to the permanent magnetA with a screw E2. The polepiece A2 is screwed into the collar E. The usual helix or coil. H i's positioned upon the pole-piece A2. The adjusting-ring D has an annularange extension b, which is provided with internal screw-threads adapted to mesh with the threads a of the collarrE. The cap B is screwed upon the vadj Listing-ring D and the diaphragm B2 is heldv between these two members. Y
From the foregoing it is evident that a chamber J is provided-by means of the cap B and the adjusting-ring D, within which is positioned the pole-piece A2, the coil H, and the -diaphragm B2. Y i
The collar E has an annular disk secured or formed therewith, (designated at K,) through which the stop-screws K2 are extended, the ends of which screws impinge and bear against the rim K2 of the adjusting-ring D.
In order to adjust the diaphragm B2 in proper position and move the-same toward and away from the end of the pole-piece A2,
it is only necessary to revolve the adjustingringD upon the collar E by means of the screw connection between them, this revolution, in fact, causing the adjusting-ring D to move back and forth on the collar, and as the diaphragm-cap B is secured to said adjusting- IOO sulating-sleeve L, screw-,threaded upon the collar E and acting as a jam-nut against the adjusting-ring, must be unserewcd wholly or partially from said collar.
\Vl1e11 the diaphragm is properiy positioned relative to the end et the pole-piece A2, the stop-screws Ks are then screwed down upon the rim KS ot the adjusting-ring D and hold the diaphragm-cap il and the diaphragm B2 in this adjusted position and form a gage by which the parts can be readily restored to the same adjustment it for any reason taken apart.
It is olten desirable to give access to the permanent magnet or to the internal wiring of the receiver er to the pole-piece and its spool without disturbing the relations of these parts. To this end in the present invention the insulating-sleeve L is so constructed that it can be slipped over the binding-screws l Z/, which for this purpose are mounted in an independent disk L of insulating material secured to the yoke of the permanent magnet in any suitable manner-as, for instance, by spacing thimbles Z2 and screws I, passing through said thimbles. The insulating-disk is of such diameter as to ht and close the bore at the adjacent or heel end of the insulatingsleeve when the latter is in position with the other parts, and this bore is continued throughout the length of the sleeve, preterably of the same diameter, but necessarily of no smaller diameter, so that when the sleeve is detached from the eollarE it maybe slipped endwise over the disk, as indicated in Fig. 2.
The adjusting-ring D, since its bere is of the same diameter as the bore of the adjacent end of the insulating-sleeve, both screwing upon the same collar E, can also be slipped over the insulating-disk and binding-screws, while the diaphragm and diaphragm-cap are removable at the opposite end o' the apparatus, leaving the permanent magnet, polepieee,helix,and receiver-wires l-t undisturbed and open for inspection and repairs.
Having thus described my invention, what I claim as new therein isl. In a telephone-receiver, a permanent magnet, a collar mounted thereon, a diamember to which the diaphragm and cap are secured, and a screw connection between the cup-shaped member and the collar whereby the diaphragm may be adjusted in proper position relative to the pole-piece together with a disk 011 the collar and stop-screws in said disk adapted to bear against the cup-shaped member and lock the parts in adj usted. position.
2. In a telephone-recciver, the combination with the permanent magnet and its accessories of thc insulating-disk secured to the heel thereof and carrying thebinding-screws, the insulating-sleeve bored lengthwise to slip over said disk, the collar upon which said sleeve screws, and the adjusting-ring also screwing Aupon said collar and adapted to slip over said
