MECHANICAL MOVEMENT.

Specification of Letters Patent. Patented Aug. 8, 1911.

Application filed July 2, 1910.- Serial No. 570,137.

To all whom it may concern:

Be it known that I, TONJES AUGUST CARL Born, a citizen'of the United States and a resident of. New York city, in the county of New York and State of New York, have invented new and useful Improvements in Mechanical Movements, .of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates to mechanical movements adapted for universal application.

More particularly it relates to a mechanical movement which will make a quick make as well as a quick break when used as the operating mechanism of an electric switch, though of course, it is to be understood that my present invention is notto be limited to such use. a

In the accompanying drawings showing illustrative embodiments of my invention and in which the samereference numerals refer to similar parts in the several figures,Figure 1 is a vertical section through an electric light socket equipped with my improved mechanical movement as the operating switch mechanism; Fig. 2 is a horizontal section on line 22 looking down in the direction of the arrows; Fig. 3 is a vertical section through the socket, a part of the structure being shown in side elevation for purposes of better illustration; Fig. 4 is a detail plan view of the center contact plate with the arm shown in substantially the same planeas the plate; Fig. 5 is a detail plan view of the blank from which the hills and valleys of the driven member are preferably made; Fig. 6 is a perspective view of the driven member with its different parts uuassembled; Fig. 7 is a perspective view, partly in section of the socket; Fig. 8 is a perspective view of one form of the screw shell; Fig. 9 is a side elevation of one form of key; Fig. 10 is a fragmentary detail view, partly in side elevation and partly in vertical section; Fig. 11 is a detail perspective and sectional view of the one piece insulating receptacle; Fig. 12 is a detail perspective view of the preferred form of compression member; Fig. 13 is a plan View of a detail; Fig. 14 is a detail view of a modification; Fig. 15 is a detail view of a metallic disk used in the construction shown in Fig. 11; F ig: 16 is a detail sectional view showing the preferred form of'securing the spring contact to the screw shell; Fig. 17 is a detail plan view of a blank from which the driven member maybemade, a portion of the figure being broken away; Fig. 18 is a detail perspective View of the driven. member formed from the blank shown in Fig. 17; and F ig. 19 is a detail vertical section showing a modified form of securing the driving member in the closed receptacle.

In the illustrative embodiments of the invention shown, 1 is an electric light socket provided with the usual or any approved form of outer shell 2 and cap 3 with the usual or any form of insulating lining 4 and 5 for the shell and cap respectively. These arethe mere outer coverings for my mechanical movement when used to operate the switch in an electric light socket and are no part of-my invention. Stripped of this outer covering my invention includes the mechanical movement shown and, when used with an electric light socket the insulating receptacle 6 closed on all sides but the bottom and the screw shell 11 for closing the bottom of the receptacle. The receptacle completely incloses and protects the switch mechanism and prevents any sparks or short circuiting of the current between the switch mechanism and the shell 2 or cap 3. As I have here shown it this receptacle 6 has substantially the form of an inverted cup having a head 8 and a mouth 9, see Figs. 1 and 11. The mouth 9 is closed by the upper portion 10 of the screw shell contact 11, Figs. 1, 3, 7 and 8, thereby-forming a completely inclosed opening 12 to receive and completely protect my mechanical movementz The screw shell 11 is held to the receptacle 6 by means of the center contact. In the preferred construction, but to which my invention is not to be limited this center contact is a plate 13, which is preferably made from stamped sheet metal by forming a blank 14 (Fig. 4) which preferably includes an arm 15pmvided with an opening 16 and is preferably screw threaded to receive the binding screw 17, Figs. 3 and 7, and generally, though not necessarily with a lug 18. At the same time that the blank is stamped it is provided with ears 19, 19. After this blank 1s stamped the arm 15 is brought up into substantially right angles to the plate 13 and the lug 18, if one is used, is bent at substantially right angles to the arm, Fig. 3. The ears 19, 19 are then'pressed downward into the position shown in Figs. 3 and 7 to form a spring center contact for the elec tric light socket 1.

Between the lower surface of the head 10 of the shell contact 11 and the upper surface of the center contact 14 I mount an insulating disk 20 of any approved construction usually a disk of mica. The center contact is then secured to the insulating receptacle 6, which is usually of porcelain, orother insulating material, by any suitable fastening means which will at the same time fasten the screw shell 11 to the receptacle 6. A very efficient means and one which I preferablyemploy are two screws 21, 21 taking through the apertures 22, 22 on the center contact, the openings 23 and 24 in the screw shell 11 and the openings 25, 25 in the insulatingreceptacle 6, their ends coiiperatingwith nuts 26, 26, Fig. 7 in the enlarged openings 27, 27 Figs. 7 and 11, in the recep tacle 6. These enlarged openings 27 being preferably, though not necessarily, non-circular to cooperate with the nuts 26, 26, and prevent their rotation while the screws are being screwed into them.

My mechanical movement comprises a driving and a driven member, and a resilient member to cooperate with the driven member and cause it to move laterally upon the driving member.

In the present invention the driving member is an axle orarbor 28 and upon this element is mounted the driven member 29 Figs. 1 and 6. This driven member 29 is in the present invention formed of a single member or a plurality of parts. The body 30, Fig. 6, of the driven member is formed substantially as a disk or plate and is provided with a non-circular opening 31 to receive the non-circular portion of the driving member 28; and is further provided with two openings 32, 32 for the reception of the fingers 33, 33 of the metallic member 34 which forms the hills 35 and valleys 36. The member 34 on which these hills and valleys are formed is preferably made from a blank 37, Fig. 5, stamped from sheet metal, though of course it may be formed from other material, and if desired even cast or otherwise formed. Preferably, however, for the sake of cheapness of manufacture it is made from ametallic or other blank 37 having an opening 38 for the passage of the driving member 28 and with wings 39, 39, Fig. 5. This blank when bent upon itself as shown in Fig. 6 forms the hills and valleys 36. One incline surface between the two hills and valleys being upon the surface 40 of the wings 39, 39 and the other incline surface being on the edges 41 41 of said saunas wings 39, as is more clearly shown in Figs. 2 and 6.

The fingers 33, 33 are passed through the openings 32, 32 of the body member 30 and.

their ends are pressed away from each other to secure them to the body member. Of course, it is to be understood, however, that this is merely one manner of securing the member forming the hills and valleys to the body member and that any suitable means may be used to accomplish the same purpose.

With the driven member I use a resilient member to cooperate with the hills and valleys. Preferably, though not necessarily, this member is a single integral spring 42, Figs. 2 and 12, having arms 43, 43 to contact with and ride upon the hills and valleys of the driven member, Fig. 2.

From the mechanism so fardescribed it is clear that if the driving member 28 is given a partial rotation of approximately 90 degrees the driven member, due to its non-circular opening cooperating with the non-circular portion of. the driving member, will also be given the same rotary movement as there is substantially no relative rotary movement between the driving and driven members. This, however, will cause the arms 43, 43 of the resilient'member 42 to be spread apart because a hill will then be forced beneath the arms where there was formerly a valley. The tension of the spring arms upon the present hill will cause the entire driven member to move laterally upon the driving member until such time as the arms 43, 43 come to rest in the succeeding valley, when the parts will remain in that position until another partial I may, as in the previous patent referred to, cut away'or notch the hills and valleys as at 44, 44 to hold the arms '43, 43 until the operating hill has forced the arms apart to their maximun'v movement, when the maximum energy will be stored in the resilient member. Substantially at this instant the driven member will complete its rotary movement bringing the arms 43, 43

out of the notches, 44, 44, onto the smooth I surfaces of the hill when the arms will instantly tend to slide down into the succeeding valley and actuate the driven member with a quick snap as previously described. These notches 44, 44 therefore tend to hold or retard the action of the spring until it has received its maximumcompression or energy.

I have shown my mechanical movement in an electric light socket to make a quick make as well as a quick break of the circuit, both of which are highly desirable to prevent arcing or burning of the interior mechanism of the socket. To doubly insure that the contacts shall be thoroughly protected and under no circumstances whatever can dirt or foreign matter get to the mechanical movement when so used, I mount it within the insulating closed receptacle 6, the

mouth 9 of which is closed by the screw shell contact, as already described. This screw shell 11 has in Fig. 8 a tongue cut out of its head 10 and bent up to form a contact 45, which extends up into the opening 12 in the closed insulating receptacle 6. Separated from but adjacent to this contact is another similar contact 144 to which the feed wire 145 is electrically connected .in any suitable manner, as by the binding post 46. i

.In the preferred construction I attach the spring contact 345, Fig. 16, to the screw shell 11 by any suitable means, such as rivets 346. In this construction it is not necessary to cutthe shell 11 to form the contact, and the contact 345 may be of different material and strength from that from which the shell is formed.

\Vhen my mechanical movement is used as a switch mechanism I secure in any suitable manner a connecting member 47 to the driven member 29. This conductingmember may be formed of various shapes and configurations. I- have found in practice that a veryeflicient conducting member is L the metallic ring 47 which is secured in any suitable manner to the driven member 29 such for example as by having lugs 48, 48 which are forced or crimped into openings 49, 49 in the insulating body member 30.

It is clear that upon apartial rotation of approximately 90 degrees of the driving member, axle or arbor 28 the driven member is also rotated to the same extent which will'cause the arms 43,43 coiiperating with the hills and valleys, as previouslv described, to move the driven member with its conductingring 47 into contact with the contacts 45 and 144 to make the electrical connection, and will move the driven member from the same contacts to break the connection. In my invention I, by the same mechanism, insure not only a quick break, but also and in addition thereto, I insure that. the make is quick and will prevent arcing or burning of the mechanism. The driving member which in this form of my invention is the key, may be given different shapes and contours. A successful and economical manner of manufacturing it is to stamp it from metal forming a key 245 having an integral feat-her 246 to cotiperate with a cotiperating opening in the driven member 29, Fig. 10. In the end ofthe key 245 as well as in the end of key v-28, I preferably form a recess 247 to coiiperate with a locking plate 248. This plate 248 is preferably dropped into a recess 249, Figs. 1 and 11, in the closed insulating receptacle 6. Its arms 50, 50 take into the groove 247 and prevent the accidental or unauthorized removal of the driving member or key 28, or 245, Fig. 9, as the case may be. This plate is held, in its position preferably by permitting itto rest upon the upper portion or head 10 of the screw shell 11, a piece of insulation 54 being interposed, if desired.

Currentis supplied for example'by the feed wire 145 passing the binding post 46, spring contact 144, ring 47, spring contact 45, screw shell contact 11, thence through the lamp (not shown) and out through the center contact 14, spring ears 19, 19, arms 15 and to the wire 51.

In the form of my invention described, the head or key 53 may be of metal as there is no need of it being-insulated. In some cases, however, I attach to the metallic hills and valleys a metallic body member 55, Figs. 14 and 15, in which casethere is no need of using a metallic ring such as 47 for the cur- 1 rent will pass directly through the body member 55 to complete the circuit. With such a construction an insulating key 56, Fig. 14, is used.

In some instances I may form my driven 1 6 member out of a single piece of material. Preferably for economy in manufacture the piece of material is some suitable sheet metal from which the blank 60, Fig. 17, is stamped. This blank is provided with an opening 16 for the passage of the axle or arbor or other driving member and with wings 62, 62. Each wingis also provided with a finger 63 which terminates in a cross arm 64. In Fig. 17 one of the fingers 63 is broken away and its cross arm 64 does not. appear in that figure.

When. the blank is bent upon itself as shown in Fig. 18, the wings 62, 62 form the hills 35 and valleys 36. One end of the 3 fingers is bent substantially at right angles to its other end and the cross arms 64, 64 are curved toward each other to form the' body or contact member 65, which makes connection directly with the spring contacts 45 and 144. The blank is also provided with the holding notches 44, 44 to hold the arms 43 of the spring 42 or other resilient member which may be.used.

In some instances I may form a recess 66, Fig. 19, in the side of the receptacle 6 to expose the end 67 of a driving member 128. In this form of member there is no groove such as 247. Any suitable locking member such as a nut or washer 68 may be secured on the end of the driving member 128 through the recess 66, after it has been passed through the receptacle 6. If desired, though it is not necessary, a locking plate 248 such as shown in Fi 13 may be em-' ployed.
