WALTER W. MASSIE, OF PROVIDENCE, RHODE. ISLAND, ASSIGNOR TO MASSIE WIRELESS TELEGRAPH COMPANY, OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND.
, OSCILLAPHONE.
, Specification of Letters Patent.
Patented May a, 1906.
Application filed Kuguat 1a, 1905. emu No. 274.727.
To all it may concern.-
Be it known that I, WALTER W. MASSIE, a cltlzen of the United States, residing at Provldence, in the county of Providence and State of Rhode Island, have invented new; and useful Improvements in Oscillaphones;
of which the following is a specification.
This lnvention relates to oscillaphones or, as they are sometimes known, wave -respone sive devices.
\ panying drawings,' forming apart of this specification. I 4
In the drawings, Figure 1 is a top plan view of an oscillaphone involving my invention,
that part of the magnet which is inclosed by the non-conducting element being shown in dotted lines. Fig. 2 is a front'elevation, and- Fig. 3 is a cross-sectional elevation, of the same.
Like characters refer to like parts throughterminals, as 4, which may be of carbon, the
tops of which are beveled to produce knifeedges to be bridged by a conducting ele ment, as 5, freely supported by the terminals or carbon pieces 4. To hold the carbon pieces their seats at opposite'sides of the insulatlng-block, I show vertically-disposed s'prm s or terminal clips 6, soldered or otherwise astened rigidly to conducting members or strips 7, secured to the insulating-block 3. The complete apparatus is firmly held on the gaging the members or strips-7 and which form the terminals, as shown. The free terminals of the springs or clips bear against the outer faces of the carbon terminals 4 to secure the result desired. This arrangement gives the apparatus a more compact and bet- 1 ter appearance, minimizes the area required in mounting, produces a more reliable contact, and permits greater range of adjustment of block in changing. its position under the conducting element or needle when using the latter against the stops.
Located in a plane below the upper surface of the insulating element of the device,
whether it be the block 3 or its equivalent, is
magnetized means, which magnetized means may consist of and preferably is a permanent magnet, for I find that I can securethe advantages of the invention with a magnetof such type, although it is believed it will be understood from what has been stated that I do not wish to limit myself in this respect.
A permanent magnet, however, serves as a simple and satisfactory medium for holding the bridging element down in solid contact with the upper edges of the terminals.
The ma net shown is denoted 8, and it is of the horses 0e form, its legs or branches being seated in bores in parallelism, or substantially so, in the block 3. The legs or branches of the magnet are introduced into the bores from one end thereoffor example, the front endwith a portion or the head end orbow of the ma net projecting from the block, so that the said projecting end can be easily reached to adjust the magnet to vary'the force acting on the conductin element or needle. The free ends of the egs of the magnet 8 are shown as abutting against pins, as 9, which may be driven down 1nto the block 3 at right angles to the lon itudinal axis thereof and across the bores t rough which said legs extend. The upper portions of the pins, which constitute convenient stop means in the present case for the conducting bridging element 5, extend above'the upper surface of the insulatin .elementand above the upper knifeedges 0 the two terminals or carbon elements 4. The pinsi9 serve as stops for the bridging element and also for the, magnet. As the magnet is located below the upper surface of the insulating-block, its ull is .in a perpenbase 2 by screws or analogous devices 7, en dicular' and downward irection, so that I can maintain the conducting element in desirable contact with the terminals. As the magnet abuts against the stops,-the conducting element or needle will be held against the said stops.
Having thus described the invention,what I claim is- 1. The combination of an insulating olement, stop means upon the upper side of the insulating element, terminals between which the stop means is l0cated,,a bridging element 7 magnet, the insulating element being bored to rest on the terminals, and a permanent to receive the magnet.
2. The combination of an insulatin element, stop-pins extended into the insu atin element and above the u per surface thereo terminals between whic the stop-pins are located, a bridging element to rest on the terminals, and a permanent magnet, the insulating element being bored to receive the legs of the permanent magnet, and said legs bearing against said ins.
3. In an o'sci aphone, the combination with a base-support, an insulating element, and terminals engaging the element and having a conducting element thereon, of conducting members secured to the element, and
nesses.
WALTER W. MASSIE.
