Specification of Letters Patent.

Patented Mar. 8, 1911.

Application filed March 25, 1910. f Serial No. 551,588;

To all whom. it may concern:

Be it known that I, PERCY W. HODGKIN- SON, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented cersures of flexible material that are folded down over the top of the bottle and secured in place by an elastic band.

. In the drawings :Figure 1 is a central vertical section of the machine with the parts in normal position; Fig. 2 is a similar view, with the parts in operative position; Fig. 3 is a horizontal section on the line 33 of Fig. 1; Fig. 4 is a vertical section on the line 44 of Fig. 2; Fig. 5 is an enlarged section on the line 5-5 of Fig. 1; Fig. 6 is a section on the line 66 of Fig. 5, Fig. 7 isa section on the line 7-7 of Fig. 5; Figs. 8 and 9 are enlarged plan views of the parts immediately below .the line 8-8 of Fig. 2, in different operative positions; Figs. 10 and '11 are vertical sections on the line 10-10 of Fig. 8 showing the parts in operative positions corresponding to Figs. 8 and 9, respectively; Fig. 12 is an enlarged side elevation of certain parts shown in Figs. 1 and 2; Fig. 13 is a horizontal sec-' tion on the line 13-13 of Fig. 12 Fig. 14

is an enlarged vertical section of a bottle with the closure placed over it, as in Fig. 1; Fig. 15 is a similar view showing the closure completed, as in Fig. 2; and Fig. 16 is a perspective view of a bottle with the closure in place.

Primarily the machine consists'of three cooperating mechanisms, namely, a frame that holds the elastic bands ready to be transferred to the bottles; a paper-feeding mechanism whereby the paper of the proper dimensions'is cut from a roll and carried to the bottle; and capping mechanism whereby the severed sheet of paper is folded down over the bottle and an elastic band transferred from the frame to the neck of the bottle, around the paper.

The frame 1 that holds the elastic bands is preferably revoluble and in the form of a ing d spider having radial, equidistant arms, from each of which depends a detachable bar 3 on which bands are strong, as indicated in Fig. 1. The lower end 4 of each bar is enlarged to retain the bands, and is conical in form so that each band as it is forced in turn from the bar is expanded sufiiciently to pass over the head of the'bottle. The drawings show the bars removably secured in sockets 5 in the ends of the arms by bolts 6.

The spider frame 1 is adapted to revolve upon a post 7 that is supported in a socket 8 in the frame 9 of the machine and secured against rotation by a set-screw 10.

The bottle Xthat is to be closed is placed upon a table 11 that is carried on the upper end of a vertically movable rod 12. .It is placed between

guides

13, 13, shown in dotted lines in Fig. 3, which brings it, radially into proper position with reference to 'the -band-carrying'bar 3,'so that when elevated by the mechanism presently to be described, the mouth of the bottleenters a recess 14 (Fig. 1) in the under side of the conical end 4 of the bar.

The band-carrying bars 3 are successively alined with the bottle in position on the table 11 by suitable means, such as teeth 15 on the hub of the spider frame 1 and a spring-pressed dog 16 on a ring 17 that is fixed to the shaft 7, the teeth being so spaced that the dog will lie between two of them whenever one of the bars 3 is directly over the position of the bottle onthe table 11,

between the

lugs

13, 13. This device is shown in Figs. 12 and 13.

The rod 12 by which the bottle is elevated is guided in a bearing 18 in the frame 9 of the machine, and is elevated by a lever 19,

with which it has a suitable connection, such as a pin 19 and slot 20. The lever 19is in turn operated by a link connection 21 with a treadle 22, that is pivoted at one end to the frame at 23, and is normally held in raised position by a spring 24. When pressure is removed from the treadle the spring 21 returns it to its elevated position, and n so doing moves the table 11 back to its ll ltlal position, shown in Fig. 1, and withdraws the bottle from the end 4 of thering-carry- The paper is drawn from a roll 25 that is supported in horizontal bearings 26, 26 n the frame9 of the machine. The paper is fed horizontally by

rollers

27 and 28, toward them to the rods 3, and the spring 53 yields and above the position occupied by the top to permit them to slide down over the coniof the bottle when the table 11 is in its lower position. A horizontal table 29 serves to support the paper, and guides 30, 30 direct it toward the bottle.

cal ends 4 of said rods.

A spring 54 between the frame 9 of the machine and the sleeve 52 tends to hold the latter against a collar 52 at an elevation The

feed rollers

27 and 28 are revolved by that will bring the ends of the fingers 50, 50 a segmental gear 31 that is pivoted at 32 to the frame of the machine 9 and 1s swung up i and down by a connection with a lever 34 on a rock shaft 35, which latter supports and is rotatably connectedwith the lever 19. The

, scribed by the return movement of the segmental gear 31 meshes with a pinion 36 fast on the shaft 37 of the lower feed roller 27 (-F 5). A ratchet 38 also fast on the shaft 37 (Fig. 5) in conjunction with a pawl 39 carried by the lower roller 27 (Fig. 6) constitutes a connection between said shaft 37 and roller 27 that rotates the feed rollers only on the upward, or return movement of the segment, under the action of the spring 24, when the treadle is released and the bottle-carrying table 11 sinks'to its lower position. Not only is the shaft 37 independent rotatively of the feed roller 27 when rotated from rightto left in Figs. 1 and 6 by the downward movement of the treadle -which raises the bottle up to receive its aper cap and band, but the feed roller is iield positively against accidental rotation in this direction'by a spring-controlled pawl 40 on the frame'9 of the machine and a ratchet 41 on the feed roller 27 (Fig. 7).

The paper for each cap is severed from the strip after it has beenfed as above detreadle to its uppermost position. This -is 4 accomplished bya horizontal knife blade 42 that is supported'bya yoke movable vertically in

guides

43, 43 in the frame 9 of the machine (Fig. 4). The knife is arran ed across the horizontal paper-supporting table 29, and enters a transverse recess in said table. The knife is actuated by a. rod 45 connected with'the inner arm of the lever 19 (Figs. 1 and 2). A sprin 47 tends to retain the knife in its elevate position, and its operative connection with the lever19 1s so arranged, as by a pin 48 and slot 49, that the knife is operated at the end of the upward movement of the treadle 22 (under-action of its spring 24) which lowers the bottle-supporting table 11, and extends the paper over the position of the bottle on said table, as

4 explained above.

The extensible bands carried by thearms 3 of the rotative spider frame are removed one at a time from whichever arm overlies the bottle on the table 11, by a pair of horizontal, separable fingers 50, 50 (Figs. 8 and 9) that are pivoted at 51, 51 to ears on a sleeve 52 that is slidable on the vertical shaft 7, and which are normally pulled toward .each other by a spring 53. The outer endsl l I I have been raised again.

conical end 4 of the rod 3, and off from it into the position shown in Fig. 2, and in doing so force the lowermost band Y over the cone 4 and thence over the head of the bottle, till it lies around the paper which has previously been folded down overthe top of the bottle by the circumferential flange 56 that bounds the recess 14 in the end 4 of the rod 3, into which the head 7 of the bottle enters.

To reset the fingers above another band Y on the arm 3 it is necessary to lock. the

fingers in their separated positions till they This is accom phshed by a dog 53 (Figs. 8 and 9), that is pivoted at one end between lugs 57 on one of the fingers 50, and is recessed at 58 at its other end to receive the other finger 50. The

dog is forced upwardly against the last mentioned finger by a spring 59 (Figs. 10 and 11). The spring causes the dog to engage the finger 50 that is adjacent its free end when the fingers are spread to their most extended positions by the conical end 4 of the rod 3. As the

fingers

50, 50 are raised and come into their initial position the dog 56 holds them separated as aforesaid until it encounters a stop 60 which depresses the dog and releases the fingers, and, as the fingers come together around the rod 3, under the tension of the spring 53, their beveled ends 61. 61 enter between the two lowest bands. When all the bandshave been removed from one of the rods '3, the spider frame 1 is rotated till another rod takes its place over the position of the bottle upon the table 11.
