SPECIFICATION forming part of Letters Patent No. 748,982, dated January 5, 1904.

Application filed April 18, 1903. erial No. 153,153. \No model.)

To all whom it Wwty concern:

Be it known that we, JAMES WALLACE PA- TON, residing in Southport, in the county of Lancaster, and HENRY GEORGE TAYLOR, residing at Egremout, in the county of Chester,

England, subjects of the King of Great Britain, (whose full postal addresses are 48 Scariebrick New Road, Southport, aforesaid, merchant and manufacturer, and 13 Buchanan |o Road, :Egremont, aforesaid, manager of tinbox works,) have invented certain new. and usefulImprovementsiu Machines for Beading Sheet-Metal Wares, (for which application has been made in Great Britain, No.2,680, [5 dated February 4, 1903,) of which the following is a specification.

This invention has for its object an'apparatus for beading, llanging, embossing, or recessing metal polish-boxes and other round articles and for crimping on the tops and hottoms of round canisters and the like.

In the accompanying drawings, Figure 1 is a sectional elevation of our machine; Fig. 2, a plan; Fig. 3, a detail view of the feeding device; Fig. 4, a detail view of the cam device. Fig. 5 is a general View of the entire machine. Figs. 6 and 7 are detail views illustrating the delivery device, the former being a plan and the latter a sectional side view 0 thereof.

Machines for beading metal polish, vaseline, ointment, and other boxes have been constructed with a beading-mandrel to receive the boxes in a horizontal position one 5 box ata time.

was put on by means of a foot-treadle, which was rather unsatisfactory, because the fit of the lid of the box depends to a very great extent on the amount of pressure brought to 40 bear on the body of the box in raising the bead. If that pressure varies, the fit of the lid will vary also, the result of whichis that some lids fit loose and others tight.

In our apparatus we provide a plate or disk A, mounted on a vertical shaft B, which is rotated by any suitable form of gear, such as C. On this disk A are mounted a number of rotary mandrels D, on which the boxes to be headed are placed, and over these there is a stationary top plate E, so that when the box is placed on the mandrel D it requires no the boxes on the mandrel D.

The pressure to raise the head holding down, as it does with the old machine, upon which the box must be held or it would fall off. This falling on is impossible with our apparatus, because the top plate E keeps Then, again, the old machine will do only one box at a time; but the present apparatus has a number of these mandrels D placed all round the disk A at equal distances apart. They are each mounted on the headf of a hollow bolt F, which passes through a'hole I in the disk A,and are fastened underneath by means of a nut G, and as there is a shoulder H on the .headfof the bolt F which engages a corresponding abutment on the inside of the mandrel D the mandrels are kept in position on the disk A. The holes I in the disk A are preferably made in the form of open slots, as indicated in Fig. 1, so that the mandrels can be adjusted toward or away from the periphery of the disk. Each bolt is mounted in an eyebolt .T in this slot, and this eyebolt has a screw-threaded shank, with the nut thereon collared between fixed abutments, so that by turning said nut oneway or the other the eyebolt with the mandrel on is slid laterally either toward or away from the periphery of the disk. Just above and outside the periphery of the revolving disk there is a Slzt- 8o tionary steel ring L on the inside of the shell M of the machine, which is of circular form,

and on this is formed a depression m, corresponding to the bead don the mandrel D. A-

box is placedon each mandrel D of the rotating disk A, and the mandrels revolving, as they must do when the boxes placed thereon, come in contact with and press against the stationary steel ring L, cause the required bead to be raised on the box. The pressure of the box on the mandrel against the statiouary steel ring is regulated by the adjustingrscrews K. These screws also act as a check to prevent the mandrels running away from their work, and when once adj usted and 5 properly checked up there is no fear of the pressure working off, and every box will get the same amount of pressure, with the result that the diameter of the boxes will be all the same size when finished and the lid will fit too the same on every box.

In our apparatus we provide in the top plate E a segmental opening N f suitable length to enable the boxes to be fed onto the mandrels as they consecutively present themselves at the opening N, and at another point we provide an opening 0 to enable the boxes that have been headed to be delivered otf the mandrels. With the old machine after the box was headed it had to' be knocked off by hand. With our apparatus, however, such is not the case. All the operatorhas to do is to feed the mandrels by placing a box on each as they become exposed while passing under the opening N in the top plate. The boxes disappear in turn under the top plate E,which prevents them from lifting up while the head is being raised, and when they arrive at the other opening 0 they are knocked off by the following device, comprising a pin P, fitted inside the hollow bolt F and having aheadp flush with the top of mandrel. This is kept down by means of a spring Q on the under side of disk A, and on the bottom of the shell of the machine just inside the delivery-opening we provide a stationary cam B. As the disk A revolves, therefore, these pins P come consecutively against the cam R, which thus raises against the pres sure of the spring Q. This knocks the boxes upward off the mandrels D. In Figs. 6 and 7 w is a laterally-disposed spring or elastic cushion against which each box abuts when it is pushed upward by the head 19 of the pin P, as indicated by the dotted circle in Fig. 6. The boxes are therefore raised through the delivery-opening (rin Fig. 6) by the cam R acting on the rounded lower end of the pin P and are lifted off from the mandrel D, so that they take up the position shown by the dotted circle in Fig. 6, before mentioned, and come into lateralcontact with the spring to. This compresses said spring and then as soon as the pin P shall have passed the cam R and been drawn down by the spring Q the box will be liberated and pushed laterally by the reaction of the spring 10 into the delivery-chute T.

U is the sloping feeding-chute by which boxes are fed to the opening N of the machine. The lowest one V in the row rests in a sloping posit-ion by spring-clips in the path of the mandrel, so that the next succeeding mandrel enters the box and carries it forward underneath the top plate, the guide W forcing it down flat onto the mandrel. The next succeeding box in the chute U takes its place and the operation is repeated. In case different-sized boxes require to be headed the mandrel can be removed and another mandrel with dilferent-sized head inserted in its place, the block that slides in the radial slots in the revolving disk being of course adjusted by means of the screw.

The invention is applicable for Hanging, embossing, or recessing metal polish and other boxes, also for other round articles and forcrimping on the tops and bottoms of round canisters and the like, besides beading.

We declare that what we claim is- 1. A machine forthe purpose specified,having a shell or frame, a rotating disk in said shell, said disk being provided with a plurality of upright rotating mandrels to receive and carry the articles to be operated on, a topplate on the said shell and covering the rotating disk, said plate fitting down quite closely to the articles on the mandrels so as to keep them in place, and said plate having in it at one point an aperture for feeding in the articles to the mandrels and at another point an aperture for the delivery of the articles after they shall have been operated on, means for feeding in one article at a time at the feeding-aperture, means for forcing the articles down upon the respective mandrels, and means, coacting with the mandrels, for operating on the articles carried by the latter.

2. A machine for the purpose specified,having a rotating disk, a plurality of upright, hollow bolts secured in the said disk, inandrels to receive the articles to be operated on, mounted rotatively one on each of the said bolts, a beaded pin slid-able in each of said bolts, the head of said pin occupying, normally, a recess in the upper end of said bolt, springs which draw down the respective bolts, and a stationary cam in the path of the lower ends of said pins, whereby as the disk rotates the said pins are pushed upward successively by said cam for lifting the articles off from their mandrels.

3. A machine forthe purpose specified,having a rotating disk, rotatable mandrels carried on the upper side of said disk, said mandrels to receive the articles to be operated on, a stationary plate over said mandrels to keep the articles in place on the mandrels, said plate having in it a feeding-aperture and a delivery-aperture, means for lifting the article olf from the mandrel at the deliveryaperture, a delivery-chute, and means for displacing the lifted article laterallyinto the delivery-chute.

In witness whereof we have hereunto signed our names, this 31st day of March, 190-5, in the presence of two subscribing witnesses.
