Application fil ed October 14,1914. Serial No. 866,570.

To all whom it may onaem:

Be it known t at I, JEREMIAH L. MA- noxny, a citizen of theUnited States, residing at New Haven, county of New Haven, State of .Connecticut, have invented an Improvement in Machines for Forming Rolls on Rubber Nipples, of which the'following is a specification.

This invention relates to machines for forming rolls or beads at the edges of the open ends of nursing bottle nipples, medicine dropp'er bulbs, finger cots, and similar articles composed of rubber or other plastic material. These rolls or heads have heretofore been fformed' by hand at a suitable periodflin the manufacture of the articles, said-{rolls'orbeadsbeing made by turning the rubber'or other material at the rough edge of the partly' completed article, and rolling -it' outwardly away from the open mouthf This method isslow and expensive, and is also likely to result in a defective or uneven product.

[The present invention has for its object to proyide means whereby this work may be dbnermechanically in a rapid, economical, and accurate manner, thereby increasing the output "and reducing the; cost, and also resulting in a more perfect and even product. With the foregoing and other objects in view I have devised the novel machine which I will now describe, reference being had to the acco npanyirig drawings, in which! Figure]. is a plan view of a machine constructed in accordance with the invention.

Fig. 2 an end view thereof looking from the right in F ig. 1. Fig. 3 is a deta l view of a portion of the forming roller and the bearings therefor. Fig. 4 is a detail view of one of'the hollow forms used in the manufactureof nursing bottle nipples, showing a partly completed nipple in place thereon. Fig. 5 is a similar i'iew showing the nipple after the formation of the roll or head. Fig. 5 is a view similar to Fig. 2 showing the partsin different positions. F ig. 6 is a section taken substantially op line 6-6., Fig. 1 with the spool gear and the forming roller, together with the support for the latter, omitted. Fig. -7 is an end view of one of the chucks shown in Fig. 6. Fig. 8 is an enlarged longitudinal sectional view showing another form of chuck. Figs. 9'and 10 are views similar to Figs. 4 and 5' respectively, showing a solid form used in the manufacture of medicine dropper bulbs with 'one of 1 the bulbs in place thereon. Fig. 11 is a detail elevation of the mechanism for controlling the vertical movements of the forming roller. on line 12 12, Fig. 6, showing the means for rotating the chucks. Fig- 13 is a detail front elevation of the cam'plate for controllin the chucks to release the forms.

Referring to Fig. 1, 15 denotes the machine frame which may be of a suitable form and size to provide the necessary supports,

bearings and guides for, the various moving parts except as hereinafter pointed out. 16 denotes the power shaft journaled in the frame 15 and adapted to be rotated from any suitable source of power, as througha belt pulley 17 fast thereon. 18 denotes a bevel gear on the shaft 16 whichmeshes with a bevel gear 19 on a driving shaft 20 also suitably journaled in the frame 15. 21 (see Fig. 6) denotes a worm on the shaft 20 which meshes with a worm gear 22 on the spool shaft 23 also suitably journaled in the frame 15. 24 denotes the rotary form carrier or spool, the same comprising a cylindrical sleeve provided with annular end flanges 25 and 26. Said spool 24 is fixed to, the spool shaft 23 by being clamped between a nut 27 and a washer 28 onthe end of said shaft and a sleeve 29 which abuts against a fixed collar30 on said shaft. 3l'denotes chucks or form holders which are j ournaled in bushings 32 having threaded engagement with tapped openings in the spool flanges 25 and I 26. 33 denotes chuck operating rods whichare slidably mounted in the chucks 31 and extend longitudinally thereof. Said rods are formed at their rearward ends with heads 34 and are normally held in their rearmost position, as shown at the top in I,

Fig. 12 is a section substantially,

34 on-the operating rod 33 of each chuck as it passes below the horizontal plane of the axisof' the shaft 23 engages the inclined upper edge of the cam plate 37 and is forced forwardly thereby against thetension of the corresponding spring 35 into the position shown at the bottom in Fig. 6. AlS as each chuck moves upwardly in the rotation of the 'shaft'23 libove the horizontal plane of the 5 axis of aid shaft the head 34 corresponding to sai 7 chuck is released by the plate 37 and the rod 33 moved rearwardly by its spring 35 into its normal position as shown at the top in Fig. 6.

1(The specific form of. the chucks 31 may be i accordance with the class of articles to be /bperated upon, and the nature of the forms used for such articles. In Figs. 6 and 7-is shown a constructionof chuck suitable for use in connection with a hollow nipple form 36, such as is shownin Figs-4 and 5. Said chuck comprises a suitable number (herein shown as three) of jaws 38 guided for 'movement in radial slots in the outerend of the body of the chuck '31. Said jaws are radially movable in said slots, but are held against complete removal therefrom by means of an elastic band 39 surrounding said jaws and engaging notches 40' therein. The jaws 38 are formed on their inner'edges with cam surfaces 41 which cooperate with cam projections 42 on the operating rods 33. The arrangement of the parts is such that when the rod 33 is forced into its normal or rearward position, shown at the top in Fig.

a '6, by its spring 35, engagement of the cam projections 42 with the cam surfaces 41 in the chuck jaws 38 causes said jaws to be thrown outwardly into a position to engage the inner surface of the holl'owform 36,

, thereby securely holding said form in position on the end of the chuck, as shown in Fig. 1. IWhen, however, the rod 33 is forced forwardly by engagement of its head. 34 40 with the cam plate 37 as shown at the bottom in Fig. 6, the, cam-projections 42'release the chuck jaws 38, permitting the elastic band 39 to draw the'saineinwardly, thereby releasing the form 36 and permitting the same to be removedandreplaced by another. I In Fig. '8 is shown :a modified formpf chucksuitable for holding solid. forms,su"ch as the form 360 shown in Figs. 9 and v10, used in the manufacture of medicine dropper bulbs. Said chuck comprises -a body 310,a sliding operating'rod 330 having-a head 340, and a spring 350, these' parts hein similar in construction, arrangement, and function to-the corresponding parts in the form of chuck last described. The body 310 is formed "at its forward end with a- .preferably integral fixed jaw 43. 44 denotesa movable jaw having a shank 45 extending 50 through and guided in a suitable opening in the fixed jaw 43. 46 denotes pinscarried by the shank 45 and engaging at opposite sides the inclined' end of a cam slide 47 guided for longitudinal 'novement on the 5 chuck body 310 and secured-to the forward end of the "rod 330. By this construction 6 and arrangement of parts it will be seen that when the rod 330 is moved into its normal or rearward position by the spring 350, engagement of the upper face of the inclined 7) end of the cam slide 47 with the upper pin 46 willrcause the movable. jaw 44 to be drawn upwardlyfthbreby tightly clamping a form 360 inserted between the jaws against the fixed jaw 43. Forward movement of the rod 330, or movement to the right as shown in Fig. *8,'c'ausesthe cam slide 47, by engagement of the lower's'urface of its inclined end withthe lower pin '46, to open the jaws and release the form held therebetween.

4'8 denotes pulle'ys on'the"chucks31 between-the bushings 32 said pulleys being secured to said chucks for rotation therewith in any suitable-manner, as by set sc'rewsu49. '50 (see Fig. 1-2) denotes abelt extending over the pulleys 48 and receiving power from any suitable source preferably from a coun'tershaft- (not shown) at'the base 6f the machine. As will be clear from Fig.12, the arrangement is such that, in the rotation of 9.0 the spool 24, as eachchuck'3'1'1s brought above the shaft 23 the pulley 4'8 theredn will be -engaged-and: rotated by-the belt 50,- a'ndas-said'chuck is brought below'the shaft 23 the pulley 48 thereof will be disengaged from the belt '50,- and at the same time the head 34 brought into engagement with the cam platel=37, so that friction of theparts serves to check the momentum-of sai chuck and stop the rotation thereof. Thespool 24 spool. The pulleys 48, by engagement with the ends of the bushings 32 serve also to hold the chucks 31 against longitudinal movement in said bushings. p Referring to Fgs. l and 2, 51 denotes a short shaftjournaled in the machine frame 15 and rotated by'means of apulley 52' which maybe connected' by a suitable belt I (notshown) with a pulley 53 on the driving shaft 20. The shaft 51 isconnected by means of a sectionof flexible with shaft 55 carrying. a forming roller 56. The roller 56 is preferably composed. of fiber for the reason that plastic or unvulcanizedrubber will 'not stick to this material. The outer end of the shaft 55 is 'journa-le'd'in bearings 57 and 58 (see alsoiFig. 3) having squared-outer surfaces. 'The'bc'aring 57 is guided-for vertical'movement in a-slot 59 inthe 'downtu'rned end 'of'an arm 60 pivoted at 61 to the machine 'frame. By means of the arm 60 the roller 56 is held in a position transverse to the chucks 31., and forms 36 thereon, and-above the same, so as to engage each of said forms asjt'approaches and passes its uppermost position in. the rotation 9 "shaftihg 54,1151.

of thespool 24. The roller 56 is disposed at a slight angle to the axes of the shaft 23, spool ,24, and chucks 31, and consequently to the direction of movement of the forms,

the direction of inclination being in accordance with the direction of rotation of the spool 24, so that the point of initial engage ment of the said roll with the forms is nearer the inner ends of said forms than the oint of final engagement of said parts, as will be c ear'from Fig. 1. The amount of said i clination may be adjusted bymo 'ng the arm 60 about its pivot61, said arm eing clamped in adjusted position by means of a clamp screw 62 having threaded engagement with a suitable part of the frame 15, and passing through a segmental slot 63 in the end of said arm beyond the pivot 61. The direction of rotation of the roller 56, as indicated 'by the arrows on Figs. 1 and 2,

. is such that the movement of the side thereof.

which engages the'forms 36 is outward with respect to said forms, or toward the body of the nipple or other article thereon.

The bearing 58 is received in a slot '64 (see Fig. 11) in a pivoted extension 65 of the upper arm of a bell-crank lever 66.pivoted at 67'to a bracket 68'bolted or otherwise secured to the frame 15. The extension 65 is pivoted'at 69 to the body of the arm of the lever 66, arrd is held in adjusted position with respect to the body of said arm by means of a clamp screw 70 having threaded engagement with said extension and passing through a segmental slot 71 in said body. o

' 72 denotes a gear secured to the periphery ,of the fiange 26 of the spool 24, said gear meshing with'a pinion 73 fast on a cam shaft 74 journaled-in the machine frame 15 and provided with a cam 75 having a groove 7 6 in which ope rates a roller. 7 7 carried by the lower arm of the bell-crank lever 66. As the cam 75 isrotated the lever .66 is oscillated on its pivot, thereby causing theouter end' of the shaft with the forming roller 56 to be raised and lowered. The form of the cam groove 76 is such as to cause a vertical movement of the roller 56 ju'st sufficient to compensate for the vertical component of the movement of the chucks 31 due to the rotation of the -spool 24, so that said roller 56 is held'in engagement with the upper sides of the forms held by said chucks during a considerable arc of their movement, aspwill be clear by-a-comparison of Figs. 2 and 5 The limits of the vertical movement of the forming roller may be varied in with the character o fthe work, andpa'rticu uarly the size of forms used, by adjusting accordance the extension upon its pivot .69. It will be observed that the flexible shaft section 5& not only.p ermits the movementslast referred to, but also, permits the angular ad.-

justinent of the arm 60 as heretofore described. l

The operation of the machine is as follows: The bodies of the nipples or other articles are 'molded on the forms 36 and 360 in any usual or Well known way, as by dipping, leaving rough or unfinished edges Z8 or 780 at the open mouths of said articles, as, indicated in Figs. 4-. and 9. Power having been applied to the machine, the spool or form carrier 24 is rotated inthe direction of thearrows on Figs. 1 and- 2. As the heads 34 on the operating rods 33 are brought into engagement with the cam plate 37, the chucks are opened or released, permitting the forms to be applied ther to, which forms are subsequently clamped to the chucks as the heads "34: move out of engagenient with said camplate. It will be understoodthat the operator, as the several chucks are brought to the lowermost point of their travel, successively replaces the forms which have been carried past the forming roller with fresh forms containing nipples or other articles to? be operated upon. As the chucks pass out of engagement with the cafn plate 37;, causing the I forms to. be securely clamped in place thereon, the pulleys 48 on said chucks are brought ito engagement with'the belt 50, causing said chucks and forms to be rotated in the direction of the arrows in Figs. 1 and 2. As each form, while being so rotated, is brought into engagement with the forming roller-56, the rough edge .78 of thenipple or other article thereon is engaged by said roller, said form-remaining in engagement with said roller during its travel through the uppenarc of its movement, and moving longitudinally of said roller.

tion of movement of. that face of the forming roller in engagement with the form beor head, this action being aided by the incli- The direcnation of the roller 56, by reason of which it will be seen that the combined movements of the form and roller in engagement are toward, or in opposition to one another, so as to cause the edge78 to roll upin the mannr stated. This operation takes place while the material ofthe nipple or other article is still in a plastic or unvulcanized condition so that saidmaterial adheres to itself as mass. As each-"fdrm 36 travels longitudinally of the must 56 the point of engagement of said formand roller, by reason of the outwardYi-nclination of the roller, moves soon as'molled up, forming a solid 1 outwardly of thefor-m, causing said roller rotating form, a shaft, a rotatable actuator for said shaft, a section of flexible shaiting connecting one 'endof said shaft with said f actuator; means for adjustably supporting the opposite end of said shaft to hold the same at a variable angle-to the direction of travel of said form, and a forming roller on said shaft and engaging said form.
