MACHINE FOR MAKING CLOsuRES FOR BOTTLES AND THE LIKE, No. 887,838. Specification of Letters Patent. Patented May 19, Application filed May 24, 190, serial No. 262,049.

This carrier receives, the packing from nection with closures of the well know above regardless of its form, (i.e., some Crown cork system.' times ring shaped, but generally in disk form,) Referring to the drawings, Figure 1 illus at delivers the packing at 9, where a trates, mainly in plan view but partially in cork plunger forces it downward into an un section an organization embodying my pres derlying cap still within the custody of the ent invention. Fig.2 is a vertical section of star wheel 7, which then carries the filled the parts shown in Fig. 1 on the irregular caps one by one in a circular path beneath a ()

4 vertical presser block plunger 26 to, over, or into, a coöperating stationary die. An in termittingly operated circular table, here termed timing' table, carries at its pe riphery a series of equidistant circular presser blocks 29 on the under sides of spring con trolled radial arms, so that when a cap with its packing stops at the die plunger 26, the latter will force the presser block into the cap, upon the packing, carry the cap into the die until appropriate pressure has been assured. The die being of slightly less. diameter than the caps, the flange of each is peripherally reduced made to tightly en gage with a presser block, when released from the die, it is carried by the presserblock. with the binding medium packing more or less heavily compressed, because of the firm (but temporary) mechanical union of the cap presser block. The timing table b its intermittent movement first presents presser block the closure thereon to a heating apparatus at 41, for fusing the bind ing medium, from thence, to the cooling apparatus at 43, after having been prop erly cooled the binding medium har dened, the finished closures or 'crowns' are automatically released from the presser blocks by a clearer at 49. Now as to a more specific description, it will be seen in Figs. 1 2 that the feed ta ble 1 is continuously rotated by way of a ver tical shaft, bevel gears 4 3, a hori Zontal shaft 2, bevel gear 1, an overly ing horizontal bevel gear 0 on a spindle pendent from the table carried in a hanger at a portion 47 of the frame. The central cover 4 of the table, the curved cover plate with the intervening channel 3 have already been referred to. For working upon plain crowns' the surface of the table may be of metal, hard paper, or wood, but for decorated crowns it will sometimes be de sirable to have a softer covering, such as leather, to avoid scratching the decorations. The star wheel 7 has multiple functions, hence it is difficult to specially designate it in harmony with its duties. It not only takes unfilled caps one by one from the feed table carries them to the cork feeder 10, but it also operates with its teeth 8 as a sprocket or gear in driving said feeder, step by step, still further in like manner with its pockets 6 delivers filled caps to the die, drives the timing table. The star wheel shaft 8 is intermittently driven by its worm gear 6, actuated from the adjacent continu ously driven shaft 66, by means of a cam 7 having a spline or worm which operatively engages with the worm gear long enough to impart required movement to the star wheel, said spline being so shaped, (i. e., straight curved,) as to afford the required rest during the remainder of its own rotation in a manner well known. These parts are similar 887,888 to those described in Letters Patent of the United States granted to Wm. H. Wheeler August 29, 190. The cork wheel, or feeder 10, shown in sec tion in Fig. 6, is horizontally journaled on to of a circular bearing plate 21, having a hub or post 21 mounted upon doweled, as at 23, to a portion of the frame of the machine held down by a clamp screw 22 which also controls a cover 61 which is not indicated in Figs. 1 2, may or may not be used. The cork wheel is composed of a heavy bot tom plate 19 provided with a rabbeted flange, an attached thin top plate which rests upon the bearing plate 21. This top plate is provided with an annular series of circular holes, which register with corre sponding holes 18 in the bottom plate 19 whenever in the course of rotation they reg ister with a similar single hole 24 in the bear ing plate 21, at which point the cork plunger 9 performs its duty. Except at this one point, the bearing plate serves as the bottom for all the holes, enables them to serve as pockets for packing disks delivered thereto from the overlying cork tube, Fig. 2. This cork tube is vertically slitted at one side is provided with a weight ' having a projected finger piece for enabling it to be lifted from the tube when a fresh supply of cork is needed, said weight assuring a E. delivery of corks from the bottom of the pile in the tube, one by one, into each pocket as it passes below. Adjacent to the tube there is a hinged finger 67 connected with an electric signal (not shown) for announcing any failure of delivery of cork to a pocket, but this con stitutes no part of my present invention. At each hole in the bottom plate, there is a pend ent boss or flange 9, serving as a gear tooth for engagement by the star wheel as indicated at, Fig. 1. The conveyer or timing table 31 is rotated step by step on its pintle 32 on a hanger 33 is provided with a series of radial arms, strongly hinged, projecting from its periph ery, each normally maintained in an elevated inclined position by a spring 62. Each of said arms carries below its outer end a pendent presser block 29, frusto-conical in form, larger at its face than at the arm, of appropriate size to properly enter a filled cap bear upon the cork disk or packing to be itself firmly engaged by the flange of the cap after the packing has been com pressed, thus enabling the presser block to maintain desired pressure on the packing until the finished closure is finally released therefrom. As already indicated the presser block arms also serve as teeth engaged by the star wheel in actuating the timing table. The corkplunger 9 is mounted on a lateral arm 11 projecting from beneath a slide 12 (in guide bearing 13 on cross bar 14), which
