, T EN HERMAN G. PAPE, OF NEW YORK, N. Y., ASSIGN OR TO RALPH A. SCHOENBERG, OF NEW YORK, N. Y., NOW BY JUDICIAL CHANGE OF NAME RALPH A. BELMONT.

- HOUSING FOR MECHANIGAL MOVEMENTS AND FASTENINGS THEREOF.

To all whom it ma "concern:

Be it known ti'at I, HERMAN G. PAPE,

of New York, in the county and State of New York have invented a new and useful Housing for Mechanical Movements and Fastenings Thereof, of which the following is a specification.

Heretofore in housings; for mechanical movements which consisted of a' plurality of parts, said parts were held together'by fastening means which included a screw or other locking appliance extending through the housing, which screw often became alive when the mech'anical movement was connected to electric wires because, among other things,a strand of the cord connected to the mechanical movement would touch the screw and give a severe shock toa person standmg might even be killed.

The main object of overcomethese and other defects and a feature of my invention consistsin completely surrounding the mechanical movement with completely insulated portions.

Another feature consists in having the ,means which holdthe parts of the housing together insulated at all points from the mechanical movement and the wires, if the latter are used. Inthe preferred form of such means Iuse .a split ring which-is not only easily put on and taken off but is com pletely insulated at all times, so. that the user feels sure at all times that he will not receive a shock, and this is-a very important advantage.

Another feature of my. invention is pro- VlSlOIl for ready removal ofthe fastening means WhICh feature is-not only of great -.utility in itself but-- adds to the feeling of i security in handling'the device because of ment.

pletely insulated. F Another feature of my invention is tha theikn owledge that that fastening is comthere is no danger of the fastening slipping Another feature is a housing consisting of a plurality of parts, which parts have interlockingportions to prevent relative movemy. inventionv is tot- I y cylindrical Shell made with an interior Specification of Letters Patent. Patented Apr. 16, 1918.

I I Application filed December 20, 1316. Serial No. 188,132.

Other features will be pointed out below. In the drawings, f Figure 1 is -a central longitudinal .sec-' tional view of a device embodying my invention; V

Fig. 2 is a section on line 22 of Fig. 1, showing the outer housing alone;

a Fig. 3 is a side elevation of the switch shown iii-Figs. l-and 2;

Fig.4 is a section on line 44 of Fig. 3 withthe interior partof the frame removed;

Fig. 5 illustrates a modification;

Fig. 6 is a section on line 6-6 of Fig. 5'; and a Fig. 7 illustrates a modification described below. p

My housing is longitudinally divided and is made up of two hollow sections 1 and 2 of. poroelaln or other suitable material and an interior part or section 3 that is inclosed and interlocked with the housing sections land 2. Each section 1 and 2 isa substanannular recess 4, the two semi-circularre; cesses 4 making up' a pocket into which the interior section 3-fits snugly. Section 3 is substantially cylindrical in form and recessed at its ends to accommodate the parts of the switch mechanism and provide a partition 5 on which said parts are mounted. Upon its exterior'the longitudinally divided housin G'and within' one of which is arranged a split spring ring8, Figs. I ahd ;5, which serves to hold the two sections together. Ring 8 is formed upon itsinner side and near its middle with a boss 9 fitting into a hole 10 provided in section 1, the engagement of boss 9 with hole 10 serving to' hold the split 11 of ring 8 away from the joints between the sections 1 and 2.

1n order to hold the two sections 1 and 2 against relative movement longitudinally the section 1 is made at each side about midway of its length with an integral'projection 12 is made with two annular grooves. 1

posts 17 and 18 to wires 19 and; 20, the entrance of which is permitted by the opening 21 formed in sections 1 and 2.

In Figs. 5 and 6 I show a modificationin which the split ring 81 has its two ends hooked inwardly to enter and engage recess 22 to prevent rotation of the split ring. Ad-

I j acent to the ends of the ring and at one side thereof member'2 is formed with a beveled depression 23 appearing in Fig. 5 and dotted in Fig. 6, the-function of this depression being to permit the insertion of a suitable tool such as a screw driver beneath an end portion of the split ring so that the latter may be readily and quickly removed and this is an important feature also for the reason that the user will feel assured that,

- onaccount of the complete insulation of the ring, he will not get a shock.

In Fig. 7 I show the two sections 1 and 2 the plane of division being crosswise of the device, section .1 having a projection 24:.

of the spring engaging the cooperating recess locate. the ends of the spring so that they will not be opposite the joints between the sections 1 and 2.

'What ll claim is:

1. A housing for a mechanical movement I comprising a plurality. of parts; and an interior separable portion interlocked with said parts of the housing and adapted to support a mechanical movement.

2. A housing for a mechanical movementcomprising a plurality of parts, one of which has a recess and a split ring having its ends engaging said recess to prevent rotation of said ring.

3. A housing'for a mechanical movement comprising a plurality of parts; and a split ring to hold said parts together, one of said parts having a depression at one side of, but adjacent to, one end of said spring to permit ready removal of the latter.

4. A housing forl a mechanical'movement comprising a plurality of interlocking parts susceptible of relative sidewise movement;

an interior separable portion pocketed and supported by said parts and adapted to sup.-

1 port a. mechanical movement; and means to hold said parts together. g

5.1 A housing for a mechanical movement comprising a plurality of interlocking parts;

- bers in 'positlon.

comprising an outer housing divided longitudinally into two parts susceptible of relative sidewise movement, and an interior separable portion on which the mechanical movement is mounted, said interior portion being interlocked with the two parts of the housing so that itis held against movement relatively thereto; means for holdin the two parts of the housing'against re ative longitudinal displacement; and means for fastening the two parts of the housing together against sidewise movement.

8. A housing for a mechanical movement comprising a plurality of parts susceptible of relative movement in a sidewise direction and in a longitudinal direction; means to holdsaid parts against relative movement in one of said directions; and an interior portion held in position by said parts and itself holding said parts against relative movement in the other of said directions.

9. A housing for a mechanical movement, comprising a support; a mechanical movement mounted on said support; a plurality of housing members for said support and said movement; and a split ring to holdsaid members in proper relation to saidsupport. 10. A housing for a mechanical movement :comprising a support; a mechanical move ment mounted on said support; a plurality of housing members for said support and for said movement, said members and said support being formed to prevent relative movement between said members and said support; and a split ring to holdsaid mem- 11. A housing for a mechanical movement. comprising asupport; a mechanical movement mounted on said support; a plurality of housing members for said support and for said movement, said members being grooved exteriorly and said members and said support being formed to prevent relative movement between said members and said support; and a split ring in said grooved exterior 'to position.
