To all whom it may concern Be it known that 1, JOHN W. DENMEAD,

, a citizen of the United States, residing at Akron, in the county of Summit and Sitate of Ohio, have invented,new and useful improvements in Dippingdvlachines. otwhich the following is aspecification.

This invention has relation to improve-- I ments in dipping machines and has especial relation to devices to be used in carrying outthe manufacture of rubber goods by what is known as the dipping process as contradistinguished from the process of making them by molding.

The/object of the invention is to provide a device by Which a plurality of forms, suitably supported, may be dipped in a siccative solution at determined intervals and after being dipped are raised, from the solution and later inverted so that the surplus undried solution will not accumulate at one point on the forms whereby better and evener articles are produced.

A further object is to make the machine substantially automatic, to be operated by a timed shaft so that the intervals between the dipping operation may be regulated as Well as the inverting of the forms after each dipping operation, and my invention further contemplates providing an mite matic shut-0E for the device when. the propertime has expired.

Nith the foregoing and other objects in view, the invention. consists in the novel construction, combination and arrangement of parts constituting the invention to be hereinafter specifically described and illustrated in the accompanying drawings which form a'part hereof wherein is shown the preferred embodiment of the invention, butit is to be understood that changes,.variations and modifications can be resorted to which come within the scope of the claims hereunto appended.

In the drawings in which similar refference numerals indicate like parts the different figures, Figure 1, is a view in side elevation of the device embodying this inl vention with portions omitted: and, Fig. 2, is a view in end elevation looking from the right of Fig. 1.

Referring to the drawings in detail, th reference numerals l, 2, and i design four upright parallel posts. each of which rounded portion 12 is a loop 13 f the tree end oi the arm has at its upper and lower ends colla s liter securing the posts to fixed supports :h as the floor and ceiling of a room. 'll poets usually consist of polished pipes an r ranged at the corners of an iinag allelograin. Extending between i as 1 and is a cross-anti 6' provided at with. bearings '2' slidahly mounted vertical reciprocation. between the and 2, and between the posts 3 an a similar cross-arm parallel with. 6 es and provided with end bearings S if to the bearings Y. The inner faces of arms are provided with a pair out ietween each of which is secured o the ends'of an upwardly-extending vs yolre 7c 10 which forms an arched iner and serves to cause the cross arms to re ceate vertically in unison with each of cured to the yoke 10 is an upv jecting strap 11 preferably provid rounded central portion 12. l nci end of which is threaded and on threaded opening in one side buckle ll which is pro ided with wins 15 for easy manipulation. Extending opposite end of the turnbuckle threaded. shaft 16 the upper end secured to the lower end of s thrones the sides of whicheirt-en Extending between the posts 5 if-shaped bracket lil held in clamps 20. The rear end of the is bifurcated .to provide a pair between which is pivot-ally moon one end of an oscillatory arm 22 the opp end of which is provided with an apeiriuie to receive the pin. 18 in the clevis 16. ljonnected with the extended end of the arna 5252 is a rope or cord 23 pass 1g over suitable pulleys i l/to a counter-we Jill/Q5 at Uglidiifilltfi end. whereby the weight of the its connected n'ieclninisr arm is further provi for a purpose to be later desrr liecured in suitable aringrs posts l and l a (1% mtt- 28 on mountml a cam 1:: under f r so of? the roller tire. reciprorai ion 1 mocha 22 to lower the yoke 10 when the roller en'- counters this cut-out portion. The cam 29 is further provided with a raised portion 31 for raising the arm 22 higher than its normal position when the roller 26 is on the main portion ofthe cam 29. The hub 32 of the cam is provided on its outer face with teeth to constitute one member of a grabclutch. Mounted on the shaft 28 is a companion clutch-member 33 having one face thereof provided with teeth to engage with the end of the hub 32 and establish clutching relation therewith. The clutch-member 33 is splined on the shaft 28 so as to be longitudinally shiftable thereto and yet be rotated in unison therewith. The clutchmember 33 is shifted into and out of clutching engagement by means of a clutch-lever 34 pivotally mounted on an arm 35 secured preferably ,to the post 3.

Mounted on the post 4 is a bracket 36 the outer end of which is provided with an aperture to-receive a shaft 37 the opposite end of which is supported by a suitable bearing 33 on the post 3 and which is omitted in Fi 1 'to prevent confusion of lines. The shaf 37 is threaded a ortion of its distance and is provided inside the bracket with a threaded nut 39 the outer face of which is formed to constitute a sprocket-wheel 40 to receive a sprocket-chain 41 the opposite portion of which passes over a larger sprocketwheel 42 on the shaft 28. The threaded shaft is revolved by means of a belt applied to the pulley 43. Mounted on the shaft 37 is an adjustable collar 44 arranged when the shaft is shifted longitudinally by means of the nut 39 to engage the clutch-lever 34 and throw it to disengage theclutch-memher 33 from clutching relation with the hub 32.

Extending between the cross-bar 6 and the complementary cross-bar between the posts 3 and 4 is a rotatable shaft 45 having fixed securely thereto a plurality of depending brackets 46-to'the lower faces of which is attached aplate47 from which depends a plurality of forms 48 on which the rubber articles are formed from repeated clippings in a siccative solution. Fixedly mounted'on the shaft 45 adjacent to the cross-arm 6 is a small spur gear 49. Mounted pivotally on a bolt or pin 50 on the cross-arm 6 is a segmental gear 51 arranged to intermesh with the beveled gear 49. The opposite end of the segmental gear 51 is provided with a friction roller which is adapted to en counter the foot 53 of a bracket 54 secured to the post 1, and positioned to encounter the roller 52 when the yoke 10 and its connected mechanism is raised beyond a certainpoint and as theroller engages the foot 53 the segmental gear !is given a partial rotation which causes a corres ending movement of the gear 49 and the s aft 45 which inverts permit the forms 48 to enter.

BEST AVAILABLE COPY the forms 48, at any time when the forms 8 have been raised beyond the point shown in Fig. 1.

Below the plate 47 is a large shallow tank 55 supported at each end by a pair of legs 56. Extending longitudinally below the tank and rotatably mounted in the members which are bent inwardly over the top of the to extend to the central line of the tank and there contact to close the tank. I preferably provide on the ends of the arms 59, weights or bars 61. Projecting outwardly from the arms'59 at one end of the tank are pins 62 provided with transverse apertures to freely receive operating rods 63 which are provided at their upper ends with apertured heads 64 pivotally mounted on a lug 65secured-to the inner face of 'the cross-piece 6. Mounted on the rods 63 are adjustable collars 66 as shown in the drawings.

Assuming that the plate 47 is provided with a plurality of depending forms 48 and the tank approximately filled with a proper siccative solution, the shaft 28 is rotated by means of the pulley 43 and as the roller 26 encounters the depressed portion 30 of the cam 29 the free end of the arm 22 will be lowered causing the forms 48 to approach the topof the tank 55. Simultaneously with the lowering of the cross-arm 6 the rods 63 will be forced downwardly causing the up per. collars 66 to encounter the pins 62 and force the arms 59 apart carrying with them the covers 60 so as to uncover the tank to As soon as the roller 26 leaves the depressed portion 30 of the cam the forms will be raised to the position shown in the drawings and the covers of the tank will be returned to their closed position; As soon as the roller 26 encounters the raised portion 31 of the cam the outer free end of the arm 22" will be raised beyond its normal position which causes the cross-arm 6 to rise in unison;

therewith, in doing which the roller 52 on the segmental gear will encounter the foot 53 of the bracket 54 causing an inversion of the plate 47 with the forms 48 and will hold them in the inverted position as long as :the roller 26 is on the raised portion 31 of the cam, which intervals can be easily determined or timed, after which the parts will be restored to the position shown in the drawings.

In view of the fact that the threaded shaft 37 is driven by the shaft 28 the tappet-col- -lar 44 will at a determined time throw the llO 1015799,, "BES AVAILABLE COPY a clutch-lever 3; into its inoperative position to disengage clutching reiation between the members Li and 53 of the clutch. From this will be seen that the parts or" the matomatically shutiiseli? otl' without any funthcr assistance.
