METHOD GE AND APPARATUS FOR ASSEMBLING ARTICLES.

Application filed August 9, 1927. Serial No. 211,690.

This invention relates generally to methods of and apparatus for assembling articles, and more particularly to methods of and apparatus for assembling core elements for magnetic coils.

()bjects of the invention are the provision of a simple and effective method of assembling core members in predetermined relation and the provision of a simple, compact and efficient apparatus for practicing the improved method.

In accordance with the general features of the invention, in one apparatus embodying the invention and by means of which the method may be practiced, there are provided a plurality of magazines for retaining core members and groups of the core members are fed from the magazines into a plurality of adjacent chambers, the cross sections of which taken together are substantially of the same shape as a easing into which the articles are to be inserted. The groups of core members are simultaneously advanced from the chambers into an opening in a transfer member where the groups formed in the chambers merge into a single larger group. The core members are then transferred into a position in another plane in advance of a plunger, operable by a suitable mechanism, and at the same time pressure is applied to form the group of members into a compact group having the desired cross section. The members are then forced by theplunger out of the opening in the transfer member and are inserted into a casing which is held upon a support during the inserting operation.

The invention will be clearly understood from the following detailed description of one embodiment of the invention, by means of which the process forming a partof the invention may be practiced, taken in conjunction with the accompanying drawings illustrating the embodiment of the invention. and in which Fig. 1 is a plan view of an article assembling apparatus;

Fig. 8 is a perspective view of a finished article which may be produced by practicing the'improved method and by employing the apparatus constituting the invention.

The accompanying drawings illustrate an assembling apparatusby means of which flat, rectangular laminations of a magnetic material may be assembled within tubular members, made of a suitable insulating material,

such as paper, to form cores around which turns of wire may be placed to make magnetic coils. However, the invention is not limited to the specific embodiment of the invention illustrated by the drawings, but the invention embraces any type of assembling apparatus included within the scope of the appended claims. 7

Referring to the drawings indetail, in which drawings like numerals designate like parts throughout the several views, the numeral 10 designates a base upon which a table 11 provided with rollers 12-12 is movably mounted between guide members 13 and 14 rigidly secured upon the base 10. A lever 16 which is pivoted upon the base 10, is connected to the table 11 by means of a link 17 for the purpose of moving the table back and forth upon the base 10.

Rigidly secured upon the table 11 is a block 20 having a plurality of angularly disposed channels 21, 22 and 28 formed therein (Fig. 5), which channels communi cats with a plurality of irregularly shaped chambers 25, 26- and 27 extending substantially centrally through the block 20 and which are separated from each other by partitions 29 and 30 formed in the block 20. Magazines 32, 33 and 3st each containinga plurality of laminations 35-35 are inserted in and retained by the channels 21, 22 and 28, respectively, in the block 20 for feeding the laminations 35-35, which form core members for the assembled articles, into the chambers 25, 26 and 27 in the block 20.. The force of gravity suffices to feed the laminations in the magazines 33 and 3% into the theblock. 37.

chambers-26and 27, while the laminations in the magazine 32 are forced'into the chamber 25 by means of a block 37 slidably mounted in the magazine 32 and which is urged toward the block by the force of springs 38 438, one end of each of whichis secured to the table 11 andv the other ends of whichare attached to cords 39-39 which pass over pulleys 40 40 rotatably mounted in apertures 4141 in the table 11,- and which cords are secured to opposite ends of The chambers 25, 26 and 27 taken together have a peripheral outlinewhich is substantially the same as that of the-opening in the hereinafterdescribed casing into which-the laminations are to be inserted, so

that the laminations when fed into the respective chambers taken as a whole assume a predetermined pattern which will most nearly conform to the opening in the case ing. In the embodiment of the-invention illustrated by the accompanying drawings,v the peripheral outline of the chambers 18: substantially circular and the part tlons 29 i and 27 in the block 20, is provided for 'si- 'multaneously forcing a group of laminations 85 from each of the chambers 25, 26 and-27 into a comb ned transfer and compressing member 45.

The transfer and compressing member 45 comprises a plate 46 pivotally mounted up on the base 10 and upon which s rigidly mounted a block 47 having a U-shaped channel 48 formed therein. A block 50 having asemi-circular groove 51 formed upon the inner face'thereof is pivohlly mounted in the channel 48 in the block 47 by means of a pin 52 extending through the blocks 47 and 50 near one end thereof. The block 50 is provided near the endopposite the one :1.

which the pin 52 is inserted with a plate-54 andsprmgs areinse'rted between the plate 54 and the block 47 to rotate the block 5O about the pin 52 away from the block 47 and to enlarge that. end of an opening 56 formed. bythe cooperation of the curved faces of the channel 48 in the block 47 and the groove 5]. in the block 50 so that the opening 56 will morereadily receive; the

laminations forced; therein by the transfer plunger 42. V

The transferring andcompressing member 45 is also provided with a handle 58 by meansof which it may be rotated intothe position shown in fullhnes in Fig.1 and in dottedlines in Fig. 4 so that the opening 56 is directly opposite the chambers25,-26 and 27in the-block 20, or it may be rotatedinto the position shown-in full lines in Fig. 4 so that the opening 56 therein is directly opposite a plunger 60 (Figzl) which is slidably mounted in a suitable support 61. The plunger 60 may be forced into or withdrawn from theopening 56 in the transfer member 45 by means of a pinion 62 rotatably ,mou'nted in the support 61, which pinion cooperates with rack teeth 63 formed upon the lower side ofthe plunger 60 and which pinion may be rotated by means of a lever 65 which is rigidly secured to a shaft '66 'to' which the pinion .62 is also rigidly mounted. Extending upwardly from the base 10 directly in the path of the transfer member 45 is a stop 69 having a plurality of bolts and a pin 77 which is rigidly secured to a sleeve 78 encircling the tube 74 extends through the slots 7 5- 75 in the tube 74 and through the innerend ofthe rod 7 6 so that the sleeve 78 serves as a handle by means ofwhich the rod 7 6 may be moved within the tube 74. The outer end of the rod 76 :is of the samecontour as the inner surface of a casing 80 into-which the laminations 35-35 are to be inserted so that when the rod 7 6 is in its extended position, as shown in Fig. 1, a casing 80 may be inserted over the rod 76 as is shown inthat figure. In the embodiment of the invention illustrated by the drawings, the casing SOlFig. 8)'into which the laininations arc'inserted comprises a tubular member made of any suitable insulating material such as paper. 'll1 operation of the above described apparatus is as follows: The sections 44 44 of the transfer plunger 42 "are inserted in the chambers 25, 26 and27. the magazines 32, 33 and 34 are filled with laminations '-35, the filled magazines are inserted in the channels 2l, 22 and 23 in the block 20 in the position shown in Figs. 4 and 5 and the block 37 is placed in the magazine 32 in operative position, as is shown in Fig. 4. The plunger 60 ismoved into the position shown in Fig. 1, the combinedtransfer and compressive member 45 is rotated into the position shown in full lines in F ig. l and l in dotted lines in Fig. 4, the rod 76 is moved into its extended position as shown in Fig.

are then removed from the chambers 25, 26

and 27 when a group of laminations will be fed by the block 37 or by gravity into each of the chambers 25, 26 and 2'7, in the positions shown in Fig. 5, The sections 4:+l4;l of the transfer plunger 42 are then.

reinserted in the chambers 25, 26 and 27, thereby forcing the groups of laminations out of the chambers into the opening 56 in the transfer member 45, the receiving end of which opening 56 is kept enlarged by the springs -55 to facilitate the reception of the laminations. The transfer member carrying the laminations in the opening 56 therein is rotated from the position shown in dotted lines in Fig. l to the position shown in full lines in that figure, in which position the block 50 comes into contact with the bolts 7O in the stop member 69 and is rotated about the pin 52 to compress the laminations in the opening 56 and form them into a compact group having the con tour of the opening in the casing 80. lhe lever 65 is then operated to advance the plunger 60 through the opening 56 in the -transfer member 45, thereby forcing the compressed group of laminations out of the opening 56 into the casing 86 supported upon the rod 76. The rod 76 is forced to the left as seen in Fig. 1, and out of the casing 80 by the incoming group of laminations until thepin 77 strikes the lefthand end of the slots -75 in the tube 74, as seen in Fig. 2, when the laminations will be properly disposed within the casing 80.

The plunger 60 is then'retracted toward the right as seen in Fig. 1 when the filled casing 80 will fall for lack of support upon the base 10. The rod 7 6 is again advanced to the position shown in Fig. 1, another casing 80 is inserted thereon and the above steps repeated. Should the laminations tend to jam while being transferred from the chambers 25, 26 and 27 into the opening 56 in the transfer member 45, the table 11 may be rolled upon the rollers 12 by means of the lever 16 to the right hand side of the apparatus as seen in Fig. 1 to withdraw the laminations from the transfer member 45 and the difficulty remedied.
