(01. 179-146) My invention relates to the class of devices capable of withstanding jars and shocks to a employed for supporting the coils used in collect degree to maintain the coils rigidly in position ing tolls for the use of telephone instruments, after they have once been adjusted and fixed in and an object of my invention, among others, place. 5.. is to provide a base which shall form a particu- In the accompanying drawing the numeral l2 larly rigid support for the coils. denotes a blank cut from sheet metal with curved One form of my improved device and the procedges I3 and I4 andtapered ends l5 joined with ess for making the same and in the practice of the curved edges l3 by rounding corners 16.

A coil supporting bar 36 is firmly secured to the tops of the bosses 29, bridging the space between them, and coils 3'! acting tocontrol movements of coin directing devices are secured to said bar.

It will be noted that in all of these operations the bosses have included three sides only, that is, they are closed on all sides within the dishshaped structure. This comprises an important feature of my invention as a very stable and rigid support for the bar 36 and hence the coils 37 is provided sufiicient to rigidly maintain the coils in position and effectually resist movement'of the coils on the support by reason of jars, jolts or other abnormal causes.

I claim:

1. A sheet metal supporting plate for telephone mechanism, said plate comprising a bottom and sides located at an angle to said bottom, said plate including a supporting boss of substantially rectangular shape in cross-section rising from the plate at the angle between said bottom and sides and with relatively angularly disposed supporting sides extending from the top of the boss to the plate on more than two sides thereof.

2. A sheet metal supporting plate for telephone mechanism, said plate comprising a bottom and sides located at an angle to said bottom, said plate including bosses of substantially rectangular shape in cross-section arranged at opposite sides of the plate at the angle between said bottom and sides and rising therefrom, and with relatively angularly disposed supporting sides extending from the top of each boss to the plate on more than two sides thereof.

3. A sheet metal supporting plate for telephone mechanism, said plate comprising a bottom and sides located at an angle to said bottom, said plate including a boss of substantially rectangular shape in cross-section rising from the plate at the angle between said bottom and sides and with relatively angularly disposed supporting sides extending from the top of the boss to the plate, said sides being continuous and unbroken from one boundary around the top to the opposite boundary of said sides.

4. A sheet metal supporting plate for telephone mechanism, said plate including a dish-shaped structure with oppositely arranged side walls, and bosses of substantially angular shape in crosssection located at the angle between the side walls and plate at opposite edges of the latter, said bosses each including a top with relatively angularly disposed supporting sides extending from the top to said plate on all sides within said side walls which form sides of said bosses.

5. A sheet metal supporting plate for telephone mechanism, said plate including side walls arranged at an angle to the plate and bosses of substantially angular shape in cross-section located against said plate and side walls at opposite edges of the plate, each boss including a top and relatively angularly disposed supporting sides extending from the top to said plate on all sides within said side walls and united at said top with said side wall, and a supporting bar bridging the interval between said bosses.

GEORGE A. LONG.
