GEORGE W. DUNBAR, OF NEW ORLEANS, LOUISIANA.
DEVICE FOR APPLYING FRICTION-TOPS T0 CANS.
Specification of Letters Patent.
Application filed March 24, 1911. Serial No. 616,606.
To all whom it may concern:
Be it known that I, GEORGE W. DUNBAR, a citizen of the United States, residing at New'Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Devices for Applying Friction-Tops to Cans, of which the following is a specification. i
This invention relates to improvements in devices for applying friction tops to cans or other like receptacles and it proposes a can 'top applying device which is provided with means for forming interengaging indentations in the annular wall of the friction top and in the adjacent wall of the seat for said top. Or, if desired, the indentations may be made only in the annular wall of the friction top, in which case they will be located below the annular wall which forms the seat for said top and will engage against the lower edge of said seat.
By the use of the device, the top is secured with greater positiveness and strength than a friction top'applied in the ordinary manner, yet it may be removed just as readily as the ordinary friction to Heretofore, in the use of friction tops, especially where the cans were large and their contents heavy, it quite frequently 'occurred that the tops became displaced from the cans when the latter were inverted or subjected to rough treatment during transit. To overcome this objection it has been proposed and practiced to positively secure thefriction top by applying solder at suitable intervals but the use of solder is objectionable because of its inconvenience and the ad ditional expense which it entails, and also because it prevents the ready removal of the friction top.
The device which forms the subject of the resent invention applies the friction top In such manner that .1t cannot be accidentally displaced; that its removal may be effected as readily as in the case of an ordinary friction top; and that solder or positive fastening devices are not requlred.
The primary object of the present nvention is, therefore, to provide .a devlce of the character stated which secures a more efiicient lockin engagement between the friction top an its seat.
Further objects of the invention are to provide a device which may be used with great facility and quickness; which is of simple and inexpensive nature; and which pins that produce the indentations referred to; Fig. 4 is a detail perspective view of one of said sliding pins; Fig. 5 is a perspective view showing the manner of using the improved device; Fig. 6 is a sectional View showing the device 1n use; and Fig. 7
is a sectional view showing the looking association between the friction top and its seat. Fig. 8 is a detail sectional view showing the indentations formed in the annular wall of the friction top below the seat for the latter.
Similar characters of reference designate corresponding parts throughout the several vlews.
The operating parts are assembled with relation to a block 1 which is preferably of wood and has the form of a cylinder, being provided with a suitably located handle 2. The main operating element of the construction shown is a plunger 3, having at its lower end an inward bevel 4. The plunger 3 works in a sleeve or bushing 5 which is fitted in a central opening of the block 1. The said opening is enlarged at its upper end to receive an annular flange 6 projecting outwardly from the upper end of the sleeve or bushing 5 and also to receive a plate 7 which is imposed on the flange 6. The said sleeve or bushing 5 is provided at a suitable point with a shoulder 8 which affords a seat for an expansive coil spring 9. The latter surrounds the plunger 3 and bears against a flange 10 provided at the upper end of said plunger, the action of the spring 9 being to force the plunger upwardly. The flange 10 works in a recess 11 provided on the under side of the plate 7 and normally bears against a flange 12 which overhangs said recess and defines an opening 13 through which a suitable toolis introduced to effect a downward movement of the plunger 3. In order that said plunger may be readily lubricated the plate 7 and the sleeve or bushing 5 are provided Patented Sept. 5, 1911. I
- being positioned against the under face of 5 for the purpose of securing said plate and the sleeve or bushing 5 to said block.
The plunger 3 cooperates with a plurality of (preferably four) radially slidable pins 16 (Fig. 4). These pins 16 are mounted between plates 17 and 18, the plate 17 the block 1 and the plate 18 being positioned against the plate 17. The plate 17 is formed with radially disposed channels 19 in which the pins 16 are fitted and with depending lips 20 at the front of said channels but of less depth. The plate 17 is also provided with a-central opening 21 and the lowenend portion of the sleeve or bushing 5 pro ects through this opening and bears against the plate 18. The said lower end portion of the sleeve =or bushing 5 is provided with recesses 22 which aline with corresponding channels 19 and form in effect inward continuations of said channels. The pins 16 are provided at their outer ends with in denting points 23 and are urged inwardly by springs 24 which are positioned between the lips 20 and shoulders 25 on said pins. To facilitate the assemblage. of *the pins 16 and the plates 17 and 18 and to prevent the accidental displacement of said pins when the plate 18 is, for any purpose, dissociated from the plate 17, corresponding walls of the channels 19 are providedwith bayonet grooves 26 and the pins 16 are provided with lateral projections 27 "which engage in said grooves. The plates 17 and 18 are secured to the block 1 by bolts or equivalent fastening devic'es28.
The friction top is indicated at A and its seat at B, these elements being of ordinary construction. The combined thickness of the plates 17 and 18 is equal to the depth of the top A.
In practice the plates 17 and 18 which correspond in diameter "with the top are positioned inthe latter and the top is forced to its seat by striking the upper face of the block 1 with a mallet or other suitable instrument. When the top is seated, resting upon its supporting. flange the plunger 3 is given a blow with a suitable instrument introduced through the opening 13, e. g., a hammer, whereby said plunger is forced inwardly against the tension ofits spring 9. -When the plunger is thus forced inwardly, its bevel t engages the inner ends of the pins 16 and forces the latter outwardly against the tension of their springs 24. When the pins 16 are forced outwardly their points 23 produce interlocking indentations C in the concentric walls of the top A and seat B.. In case the top is of greater depth than the seat the. indentations may be formed in the top only and will engage against the lower edge of the seat, as shown in Fig. 8. These indentations, while they can hardly be referred to as positive locking devices, are effective to provide a more secure association of the top and the seat than heretofo're, where friction only has been relied on for the purpose. VVhile the indentations C efliciently provide against accidental displacement of the top from its seat they do not interfere with the ready removal of the top in the ordinary manner. After the operation of the plunger in the manner explained, the spring 9 restores the plunger to its initial position and the springs 24 perclaim:
