RUBBER-DISK ATTACNHERwr-'OR BoTTLE-sToPPERs.

SPECIFICATION forming part 0f Letters Patent No. 728,351, dated May 19, 1903.

` Application filed July 19, 1902. Serial No. 118,298. No model.)

FIELD, residing at Mount Washington, in theA county of Jackson and State of Missouri, citizens of the United States,.have invented cer-y tain new and useful Improvements in Rubber-Disk Attachers for BottlefStoppers, of which the following is a specification.v -f

This invention relates to rubber-disk attachers for bottle-Stoppers; and our object is to produce means for disposing the disks in place easily and quickly without injuring them. Y

To this end the invention consists in certain novel and peculiar features of construction and combinations of parts, as hereinafter described and claimed, and in order that it maybe fully understood reference -is to be had to theV accompanying drawings, in which- Figure 1 is afperspective view showing the attacher as arranged'for disposing a rubber disk upon a porcelain bottle-stopper. Fig. 2 is a horizontal section of the same'. Fig. 3 is a vertical section of the same. Fig. 4 is an inverted plan view of part of the split barrelclamp.

Referring no w to the drawings in detail, 1 designates a base-plate, Apreferably of cast met-al and providedwith anv arm 2. In practice the plate is preferably secured to van upright with its arm lprojecting horizontally; but it may be secured upon a table with said arm projecting vertically upward. In opposite sides of the arm near the base are cavi-I ties 3, and extending through the outer end of the arm at right angles to said cavities is a pivot 4, upon which is mounted the members 5 of a clamp, thejaws of theclamp-being semicylindrical in cross-section in order to form a tube or barrel when closed. The bore of this tube or barrel is by preference conical, as shown at 6, and is formed at one side (its lower side when arranged horizontally) with a slot 8, formed by cutting away the edges of the jaws, as at 7, the object of this slot being to enable the spreader, hereinafter referred to, to be more readily dislodged when necessary. The bore is sharply choked at its front end, as at 8, to insure close connection with wholly or partially entering the barrel-clamp with the spreader. e

9 designates a pair of coil-springs which engage the cavities Sat their inner ends and at their outer ends sockets 10 of the handle ends of the clamp and tend to hold the jaws of the :latter together.- A

11 designates a pair of intersecting levers pivoted to boss 12 of plate l and constituting a pair of pincers, the jaws 13 of the same being provided with recesses 14 to engage the outer sides of the handle ends of the clamp members. The handle ends of the pincers are connected by a cord or other iexi ble connection 15, and this is connected in turn by a cord 16 with a foot-lever or treadle 17, pivoted to 'work vertically in a bracket 18, secured to a'wall or other support, the arrangement being such that foot-pressure on the lever or treadle operates the pincers against the resistance of springs 9 and opens the jaws to enable the spreader, presently described, to drop or be drawn out ofthe clamp.

f It drops out through slot 8 when the clamp occupies a horizontalr position and is withdrawn when the clamp is arranged vertically.

The spreader 19. is of conical form and dished at its base,V as at 20, and is forced partly through the rubber disk, as at 2l, the latter being rst lubricated for easyimovement on the spreader by being dipped-in Water. The spreader is then forced into the barrel-clamp until the disk comes in contact with the end of the barrel, as shown in Fig. 1.

When it is desired to equip a porcelain stopper, as at 22, with a rubber disk, the' attenuated end of said stopper beyond and of greater diameter than the groovedportionzis fitted inthe dished end of the spreader, and then sufficient pressure is brought to bear. upon the stopper to force the spreader into the clamp until the rubber disk registers with and snaps into the groove of the stopper, this action being rendered positive and reliable because the close t between the spreader and choked end of the barrel prevents the disk from getting pinched between them, and consequentlyinvariably eects its proper deposit IOO on the stopper. Immediately after this takes place the equipped stopper is thrown aside, and by depressing the lever or treadle, and thereby throwing the jaws apart, the spreader is permitted to drop down through slot Sinto the operators hand or upon the workbench.

In Fig. 3 is shown an ordinary wire stopper 24, the same being provided with a head 25 at one end and a smaller enlargement 26 a slight distance from said head, so as to provide a space between them to receive a rubber disk. l/Vith this type of stopper, it is preferable to use a spreader, as at 27, provided with a slot 28 and a hole 29,1eading from its base to said slot, the base being of course dishedorconcaved,ashereinbefore explained. Upon this spreader the disk is placed in the manner already explained, and then the spreader is inserted in the clamp. The free end of the wire stopper is then slipped through the hole 29 in the base and through the registering slots 28 and 8 or, if no slot 8 is provided, through the space between the jaws, as the latter will be forced apart some distance by the insertion of the spreader. The stopper is then manipulated in such a manner that the enlargement 26 ts snugly in the dished portion or cavity 2O of the spreader, as shown by dotted lines in Fig. 3. The op erator then by means of the butt-end of an awl or other equivalent tool forces the spreader inwardly between the jaws until the disk is forced beyond the end of the spreader and snaps upon the wire stopper between its head 25 and enlargement 26. The spreader may then be withdrawn by pulling outward on the stopper, or the stopper may be first withdrawn and the spreader withdrawn by slipping the small end of the tool through the slot 28, or it may be removed by opening the clamp in the manner previously described.

The above-described manner of equipping the wire stopper with the rubber disk is the preferred one; but it may also be equipped by slipping the disk over the head 25 through the medium ot' a clamp and a spreader of proper proportions, as will be readily understood.

Heretofore all devices for attaching rubber disks to Stoppers of the types shown have usually been instruments which were inserted `in the holes of the disks, stretching the latter and slipping them upon the Stoppers, which operation was frequently attended byinjury to the disks.

By the use of our spreaders the disks can be attached to the stoppers with the danger of tearing the former practically eliminated, and such operation can also be performed much more expeditiously than in the old way.

Having thus described the invention, what we claim as new, and desire to secure by Letters Patent, is-

l. A rubber-disk attacher for bottle-stoppers, comprising a split tubular clamp, and a disk-carrying spreader to be forced into said clamp until the latter pushes the disk olf the end of the spreader onto the stopper.

2. A rubber-disk attacher for bottle-stoppers, comprising a split tubular clamp, and a disk-carrying spreader to engage the clamp and provided with a dished or recessed base.

3. A rubber-disk attacher for bottle-stoppers, comprising a split tubular clamp, and a disk-carrying spreader, provided with a slot and hole opening from said slot through its base.

4. A rubber-disk attacher for bottle-stoppers, comprising asplit tubular clamp, adiskcarrying spreader to be forced into the clamp, and means to move the jaws of the clamp apart to efect the extraction of the spreader.

5. A rubber-disk attacher for bottle-stoppers, comprising a split tubular clamp, composed of two members. pivoted together and having the inner faces of one end of said members recessed, the front end of the recesses being segmental and of smaller diameter than the body portions thereof, said recesses conjointly constituting a bore having its front end choked, springs for holding the jaws pressed yieldingly toward each other, and a disk carrying spreader, circular in cross-section, to be forced into the clamp until the ends of said jaws push the disk off the end ot the spreader onto the stopper.

6. A rubber-disk attacher for bottle-stoppers, comprising an arm, a tubular clamp consisting of two members pivoted together and to said arm, springs bearing at their opposite ends against said arm and the handle ends of said clamp members, pincers engaging said handle ends, and a foot-lever or treadle connected to the pincers to operate the same and thereby open the clamp.

7. In a rubberdisk attacher for bottlestoppers, a split barrel-clamp having its jaws pressed yieldingly together and the bore of its jaws choked or contracted at its front end.

8. In a rubber-disk attacher for bottlestoppers, the combination of a split barrelclamp having the front end of its bore choked or contracted, and a conical disk-carrying spreader to be forced like a wedge into said split barrel-clamp.

In testimony whereof we affix our signatures in the presence of two witnesses.
