MECHANICAL MOVEMENT.

Specification of Letters Patent.

Patented Jan. 30,1912.

To all 'whom 'it may concern Be it known that I, ToNJEs AUGUST CARL BOTH, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Mechanical Movement or Means for Converting Motion, (Case H,) 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 and more particularly for converting reciprocating to rotary vor racking motion, and is an improvement upon U. S. patent granted Jan. 30, 1906 to Ralph A. Schoenberg, as the assignee of Charles J. Klein, No. snare.y 1 i I have shown mymecha-nical movement operating' a. pendantswitch and adapted to make and break the circuit therein, though it is to be distinctly understood that my invention is not to be limited to this or any other particular use. l

My invention further relates to a pendant switch which includes my mechanical movement, all of which will be hereinafter described in the specification and pointed out in the claims.

In the accompanying drawings showing illustrative embodilnents of my invention, and in which the same reference numerals refer to similar parts in the several figures, Figure 1 is a top view of my invention used as a pendant switch, the cap and insulating disk being removed; Fig. 2 is a vertical section on the line 2-2 of Fig. l. illustrating my invention used as a pendant switch; Fig. 3 is a horizontal section on line 3-3 of Fig. 2; Fig. 4; is a vertical section substantially on the line 44 of Fig. i2; Fig. 5 is a detail perspective view of the rotary or rocking body driven member; Fig. 6 isa side elevation of my vpendant switch, the cap being removed from the insulating protecting base, the locking rings being. shown in section; Fig. 7 is a detail persoecti-ve view of one of the tension members; Fig. 8 is a detail perspective viewof the preferred form of movable contact; Fig. 9 is a detail View of'one of the binding posts; Fig. 10 'is a side elevatio'n of the other binding post;`

In the illustrative embodiments of the invention Ishown in the drawing, l is a pendant .switch which includes my mechanical movement to operate the movable contact 2, Figs. 1 and 8. It is, of course to be understood, however, that my mechanical movement is not to be limited in use to operating a movable contact of an electric switch.-

-Mymechanical movement consists essentially of a rocking driven member 3, Figs.

2, 4 and 5 which is provided between its entary detail sectional yiew of ,afi

ends with a paii` fecoperat-ing inclined surfaces 4 and 5 having aclilmon meeting edge 8. I also preferably provide the rockving driven member with another pair of cooperating inclined surfaces 6 and 7 having a similar common meeting edge l0.

Upon preferably each pair of inclined surfaces 4, 5 and 6, 7, a resilient member 12 is caused to operate, one resilient member for each pairV of inclined surfaces, Figs. 2 and 7 though it is to Ybe understood, of course, that my invention will voperate successfully with only one pair of inclined surfaces and one resilient member cooperating with both inclined surfaces. These resilient members 12 are preferably formed out of a single piece of metal such 'as spring metal, preferably stamped out ofy a single piece and bent into the position shown so that they will preferably, though not necessarily, be composed of two side members 13 and 14, the meeting surfaces of these two side members being preferably formed in a segment of a circle l5, to add additional strength to the resilient member 12 and to increase its resiliency and longevity. One of the side members 13 is provided. with a laterally extending finger 10 which lies in an aperture within the reciprocating member 17 or 18 which is the preferred means 'of securing the resilient member to the re- `ciprocatimg; member. AThe other side membei* 14 has its end 19 preferably bent slightly `Athe point 21 on the surface 5.

back upon'itself to form a curved engaging surface to contact with the inclined surfaces 4, and (i, 7 of the rocking driven member 5, it being understood that the end 19 of one resilient member will cooperate with only each pair of inclined surfaces passing over their meeting edges to get from one inclined surface to the other inclined surface of that pair. It is, of course, to be understood that the rounded end of the tension member 12 may be omitted and that the signal integral spring may be otherwise shaped or formed without departing from my invention.

The rocking driven member 3 is supported in any suitable manner which will permit it to have free rocking movement, but prevent any lateral movement on its part. One or both, if two are used, of the resilient members 1 2 are reciprocated so that the spring member or" members will contact with each pair of inclined surfaces 4, 5, and 6, 7 which will cause the rocking driven member 3 to alternately rock with a quick snap, which can be used for many different purposes and in many locations where such a movement is desirable. For purposes of illustration I have shown the alternate rocking of the rocking driven member 3 alternately rocking the movable electrical contact 2.

ln using simply one of the resilient members 12 with the rocking driven member 3, the reciprocation of the tension member, which -for purposes of illustration We will assume has its member 19 resting upon the surface 20, Fig, 5, of the rocking driven member will cause this member 19 to slide upon the inclined surface 4 until it reaches substantially the edge or point 9 when the member 19 of the resilient member 12 will instantly fly over or snap onto vWhile this resilient member is moving from the point 29 to the point 9, the side member 14 is made to approach the side member 13 and store up energy in the resilient member. This energy is instantly released by the side member 14 springing away from the side member 13 the moment that the engaging surface 19 of the resilient member passes or snaps from the point 9, Fig. 5, to the point 21 on the surface This Inovemcnt, of course, will cause the rocking driven member 3 to rock with an instantaneous snap. i

When the engaging surface 19 of the resilient member 12 is reciprocated from the point designated 21 on the surface 5 to thc point designatcd20, Fig. 5, on the surface 4, it will travel along the inclined surface 5 until it reaches substantially the point 11, the side member 14 being meanwhile caused to approach the side member 13, nwhen the engaging surface 19 of the side member 14 will fly or'snap instantly -ver onto the pointdesignated 20 on the other surface 4, thereby again rocking the member 3 with a quick snap but in the reverse direction from that previously described.

The cooperating inclined surfaces 4, 5 and 6, 7 are preferably formed as illus- "trated inthe drawing to permit the cumulative action of the resilient members 12, 1.2 to positively operate the rocking driven member 3. This alternate, or reverse reciprccaticn, of the resilient members 12, 12 may be accomplished in various ways. For purposes Yof illustration I have shown each of them mounted upon the reciprocating members 17 and 1S, which are, in turn, connected to each other in any suitable manner such as by a lever 22; this will insure that as one of the resilient members 12 is moved from the point 20 to the point 21, Fig. 5, the otherresilient member 12 will be simultaneously operated in the reverse direction. The two ends 82, 82 of the lever 22 cooperate with enlarged apertures or openings 83, 83 in the reciprocating members 17 and 18. It is, of course, to be understood that the movement of the second resilient member on the second pair of inclined surfaces 6, 7 will be exactly similar' to the action just described, except the reeiprocation will be reversed.

While my mechanical movement or means for converting motion is adapted for general application, I have for the purpose of this application shown it in combination with 'and as the operating mechanism of a pendant. This pendant. switch 1 includes a single yhollow insulating base 23 in which my mechanical movement, and the movable contact 2 being all the operating mechanism of the pendant switch, are received and thoroughly protected. Preferably, though not necessarily, this insulating base is formed cylindrical and is provided at one end with/two openings 24 and 25 within which operate the recilirocating members 18 and 17 which, when myvinvcntion is used as a pendant switch, are push buttons.

On the interior of the insulating base 23 l form an annular flange 2G upon which they support 27, Fig. 12, rests. This support is preferably formed out of stamped sheet metal and from a blank 28, Fig. 11. llVhen this blank is bent into' the shape shown in Fig. 12, to form the colnplete support, 'it comprises legs 29, 29 which are apertured at 30, 30 for the reception of .the axle or arbor 31, Figs. 2 and 4, upon which the lever 22 is mounted. Connecting these legs 29, 29 is the cross piece. 32 having an integral arm 33 which is bent down between thelegs 29, 29

to be substantially at right angles to the' cross piece 32and furthermore it is apertured at 34 to form a bearing for the concentric trunmon 35 of the rotating or rocking body driven member 3, Figs. 2, 4 and 5,

it being understood that the pairs of coperating inclined surfaces 4,5 and 6, 7 arevarranged eccentric to the trunnions 35 and 40.

To prevent the support 27 from having relative movement to the insulating base 23 within which it is mounted, which would be objectionable, I preferably form the legs 29, 29 of sufficient length to rest upon the inturned flange 26 and to let their otherV ends 36, 36-substantially coincide with the horizontal shelf 37 formed in the upper portion of the single insulating base 23. Resting upon this shelf 37 and contacting With the ends 36, 36 of the support 37, I mount any suitable holding plate, preferably in the form of a fiber bridge 38, Figs. 4 and 13. This bridge plate is apertured at 39 to form a bearing for the other concentric trunnion 40, Figs. 4 and 5. This trunnion 40 is eX- tended and preferably formed with a non- .circular portion 4l, Fig. 5 and with a screw threaded portion 42. Upon the non-circular portion 41 I mount the movable contact 2 which is provided with a non-circular aperture 43, Fig. 8 to 'lit over the portion 41. This movable contact 2 is preferably formed of two plates 44, 44 of conducting material preferably stamped out of sheet metal and connecting by a piece 45, Fig. 8. It is therefore provided at each end 46, 47 with a bifurcated arm adapted to receive between the plates 44, 44 the fixed Acontacts 48 and 49.

The fixed contact 48 is preferably formed of an integral portion of the binding post 50, Figs. 1 and 9, the post having two screw threads 51, 52, the former to coperate with the screw threads upon the locking screw 53, Fig. 4 .vhich is passed up through the opening 54 in the base 23. Similar screws 53 are used to secure the binding post- 57. The ends of these screws 53 pass through the plate or fiber bridge 38 which is immovably secured to the base 23 by the same binding screws 53, as hold the binding posts 50 and 57 in their proper position. The movable contact 2 is kept in its proper position on the non-circular portion 41 of the rotary or rocking body driven member in any suitable manner such as by the nut 55.

After the parts are all in their proper position in the single inclosing and protecting insulating base 23, I preferably mount over them an insulating disk 56 preferably of mica, Fig. 3. To secure this disk in position a-nd prevent its displacement I use these binding posts which are of peculiar configuration. Y

The binding post 57 to which is connected the fixed contact 49 is provided with an upwardly extending arm 58 provided with a slot 59. In positioning the insulating disk of mica, or other suitable material 56, after the mechanism has been inserted inthe insulating protecting base 23, I place one edge of 1t in the slot 59, bringing it substantiallyl horizontal with the shelf 37 and then bend down the end 60 of an upwardly extending arm 61 preferably formed integral with the binding post 50, Fig. 9.

fter'my mechanical switch has been 1nstalled in the insulating base 23 so that it is thoroughly housed and protected, I close the upper portion of the insulating member 23 v by means of a cap 62 preferably of insulating material and preferably the same as that of the base 23. The feed Wires 63 and 64 are passed through the,4 mouth 65 in the top ofthe cap and around a bridge piece 66, their ends being then connected with the re- .spective binding screws 67 and 68. Instead of knotting the feed wires 63 and 64 forming a knot which ordinarily couldrnot be easily pulled through the opening 65 in the" to connect the feed wires is reduced and consequently the cost of labor, besides saving the additional wire which would be used to form a knot.

The cap 62 may be connected to the insulating base 23 in various ways. I may for example provide the cap 62 with an opening (59 for the reception of the screw 70, Fig. 14, and provide the base with cross holes 71, one cross hole for each screw 70; it of course being understood that the construction shown in` F ig. 14 is duplicated. 1V ithin these cross holes 71 I may mount any suitable plate or other member. such as a nut 72 which will coperate with the screw threaded end ofthe screw 70, and in this manner connect the cap to the insulating oase 23. I have found in practice, however, that it is much more expensive to'cast porcelain or other insulating material of which the base would be formed with cross holes, and furthern'iore it is if'eryxliflicult to plug up the openings such as 69 and the cross holes 71 with wax, composition, or

other material, which willliave the same Y color as that of the cap (i2-and base 23, it

heilig understood, of course, that preferably the insulating cap and base are glazed to present a neat and handsome `appearance. and sometimes the glaze is given any desired color. Pluggingup thesediiferent openings with materials varying in color or shade from the insulating base and cap, for it is 4'impossible to absolutely vmatch the color t pulled away from the binding screws 67 and 68 and materially re- (luces the cost of installation in that the time ofthe glaze on the cap and base, mars the appearance of the pendant switch. To overcome this objection and to obtain a better' and cheaper construction l, in the preferred form of my invention, form an annular flange 73 upon the insulating` base Q3 and a'similar annular liange 7% upon the insulating cap (3Q, Figs. Q, 4; and 6. To cooperate with these franges so that the cap (32 and base may be positively connected together, l may use any suitable locking means. Preferably I use two locking rings 75 and 76, the ring`75 having a reduced portion 77 to fit over the flange 7l on the cap, and the ring 7G having a similar reduced portion 78 to perform the same function with the annular tlange 73 on the insulating base 23. rlf'hese rings may be formed with any suitable cooperating locking surfaces. I have found in practice that a very efficient cooperating locking surface are screw threads, the female thread being formed upon one of the locking rings, for example thev locking ring 75, and the male locking screw thread being formed for example on the other locking ring 76,

though of course this arrangement may bev reversed, or any other suitable locking rings or members may be used.

To `ive a neater appearance to my pendant switch and to protect the push buttons 17 and 18 from accidental blows, and also to very largely conceal them, l provide the under surface of the insulating base or receptacle 223 with downwardly extending ears 79, 79, Figs. 4. and 2. very citer-"tally conceal the push buttons exceptwhen the observer is in line with both push buttons.

To permit the cap to be readily seated and properly positioned with relation to the base 2f-E, and also to prevent relative rotation between the cap and base, I preferably, though not necessarily` Jform a recess 8() on the upper portion of tht-,base Q23 and a tongue S1 on the lower portion of the cap ($2 Yto litwithin thc-recesses SO of the base 23, though of course, it' is to be understood that this arrangement may be reversed, or any other similar means may be used, or that such groove and tongue may be omitted without departing from my invention.

ln my pendant switch preferably no metallic or other covering is used to incase the base 23 andcap (32, orany portion of them. ()n the conti-mythe insulating` base and cap are preferably glazed as previously noted, or decorated iny any suitable way so as to present an artist ic appearance. 'lhe cost therefore of a metallic. casing is dispensed with and if the base and cap are glazed they present a surface which can b e easily cleaned. When locking rings ai'e used such as 75 and 7f3, they may be formed ol' dit- ;l'crcnt materialaml if of metal they would These ears serve tov 1,ois,sco

tend to enhance the appearance and beauty of the pendant. switch.

It. will be further noted that the insulating inelosing base 3 in addition to inclosing and protecting the mechanical movement also serves as a guide for the push buttons 17 and 1S.

By using my invention a quick. or instan,n taneous make of the electrical eurreftt, as well as a quicker instantaneous break of it, is insured, preventing arcing or burning out of the mechanism.
