Patented Sept. 15, 1931 UFNITED'STA'TESI PATENT OFFICE HARRY J. LEBHERZ, OF FREDERICK, MARYLAND, ASSIGNOR TO THE EVEREDY COM- PANY, OF FREDERICK, MARYLAND, A CORPORATION OF MARYLAND BOTTLE CAIPER Application filed October 12, 1929. Serial No. 399,259.

a My invention relates broadly to bottle cappers and more particularly to a manually operated bottle capping tool.

One of the objects. of my invention is to provide a construction of hand operated bottle capper Which will enable relatively large forceto be applied in affixing a crown 1 cap upon a bottle by movement of a plunger downwardly upon the crown cap of a bottle.

Another object of my invention is to provide a construction of plunger type bottle capper having means for readily adjusting the position of the plunger for capping bottles of different heights.

A further object of my invention is to provide a plunger typebottle capping tool having the operating parts thereof substantially enclosed by the standard which supports the bottle capping mechanism with means for readily adjusting the position of the bottle capping plunger with respect to the standard which supports the plunger, thus enabling thebottle capping tool to be readily used on bottles of difierent sizes.

A still further object of my invention is to provide a plunger type bottle capping tool in which pressure may beapplied for actuating a plunger with respect to a bottle by the movement ofa hand lever in one direc-' tion which pressure is removed from the plunger and the plunger adjusted in position with respect to the supporting standard for utilizing the bottle capping tool upon bottles of different sizes. I

Other and further objects of my invention reside in the construction of bottle capping tool set forth in the following specification and illustrated inthe accompanying drawings, in which: v

Figure 1 is a side elevation of a bottle capping machine constructed in accordance with my invention; Fig. 2 is a frontelevation thereof; Fig. 3 is a fragmentary side elevation with the operating handle turned forwardly in the direction ofthearrow in order to apply a cap to a bottle; Fig. l is a similar View but with the handle thrown rearwardly in the direction of the arrow and showing the stop arm abutting the frame, in 0 order to raise or lower the rack gear plunger;

Fig. 5 is a detailed vertical sectional view on a somewhat larger scale taken on line 5-5 of Fig. 6; Fig. 6 is a horizontal sectional View taken on line 6-6 of F ig.2; and Fig. 7 is a perspective view of the mutilated gear and adjacent parts.

Referring to the drawings in more detail, reference character 1 designates the standard for the bottle capping tool of my invention. The standard may be cast integral with the base 2 and the head 3 providing an extremely simple construction which is rigid and capable of inexpensive manufacture on a quantity production basis. The head 3 is provided with a vertically extending bore 8 5 therein and immediately behind the bore 8 there is provided an enlarged horizontally extending bore 4 which communicates with the bore 8. A shaft 5 extends through bore 4 on a horizontal axis. The shaft 5 being milled toprovide gear teeth 6 throughout a portion of its circumference and being ground into a flattened portion 7 at one side thereof. A plunger 9 passes through bore 8 and is provided with a rack 10 at one side thereof, which is en ageable by the teeth 6 of rotary shaft 5. lunger 9 carries a bottle capping throat 18 in the lower extremit thereof, which throat is placed over the nee of a bottle supported on base 2 during the process of applying a. crown cap to the bottle. The capping mechanism is assembled by means of spring latch 11 having spring arms 11a which fit into the groove 5?; formed on the portion 5a of the rotary shaft 5 adjacent the end thereof, the spring arms 11a extending around the groove 5?) in such manner that the rotary shaft 5 is secured in position for rotative movement but prevented from moving. transversely and thus becoming dislodged from the bottle capping head. The shaft 5 is rotated by means of a lever 12 having a handle 14: thereon which extends through shaft 5 as shown more clearly in Fig. 7. A collar 15 having a sleeve 15c fits over the shaft 5. The sleeve 150 has diametrically opposite notches 15d cut therein, which notches must be registered with lever 12 in securing collar 15 in proper position withrespect to rotatable shaft member 5, 1M

7 grees around the collar 15.

that is in a' position where abutting arm 15a and hook 156 are properly positioned for the proper cooperation of the parts of the bottle capping throat. Collar 15 carries the limiting stop 15a which extends radially from collar 15 and hook-shaped member 15? angularly displaced :at approximately 90 de- A coil spring 16 extends between the hook-shaped member 15?) and the. fixed point 17 on the standard 1 for exerting a turning torque on collar 15 and through sleeve 15c and the interlocking of notches 15?) with lever 12 upon shaft '5, thus restoring lever 12 to a bottle capping position and elevating plunger '9 after each successive bottle capping operation. Where it is desired to adjust the position ofplunger 9 with respect to the bottle on which the :bot tle capping toolis operated, the hand lever 12 may be reversed in its position until the end of the limiting stop 15a strikes the outstanding rib la of standard 1, thereby bringing the flattener portion 7 adjacent the teeth 10 on plunger 9, enablingthe plunger to be i readily slipped upwardly or moved down wardly to a selected bottle capping position.

Fig. 4 illustrates the position of hand lever 12 when plunger 9 is being adjusted vertically to aposition for applying crown caps to bottles of selected sizes. Fig. 3 shows a hand lever moved to an opposite position where the teeth 6 on shaft 5 again mesh with the teeth 10 on. plunger 9 and enable the plunger to be moved downwardly under pressure for applying a crown cap to a bottle. The bottle capping throat 18 is provided with a double seal die head19 by which a crown cap may be permanently sealed upon the neck of the bottle. 7

The double seal feature which employ in the capping throat or die head .isshown more fully in my Letters Patent No. 1,421,- 698, issued July 4, 1922.

The plunger'type bottle capper described herein has been found to beextremely practical in its manufacture and productiomand while I have described a preferred embodiment of my invention, I desire that it be understood that modifications may be made and that no limitations upon my invention are intended other than are imposed by the scope of the appended claims.
