EDVVARD D. SCHMITT, F BALTIMORE, MARYLAND, ASSIGNOR TO AMERICAN BOTTLE CAP C01VIPANY, OF BALTIMORE, MARYLAND, A CORPORATION OF DELAWARE.
BACK AND PINION.
Application filed September 9, 1911.
T 0 all whom it may concern:
Be it known that 1, EDWARD D. SCTIMITT, a citizen of the United States, residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Racks and Pinions, of which the following is a. specification.
This invention relates to machines for applying bottle caps.
The primary object of the invention is to provide a mechanism for reciprocating a head of a bottle-capping or other machine a maximum distance, or for the entire length of a stroke, by a minimum distance of movement of the operating-member, so that the movement of the foot of the operator required to manipulate said operating-member will be slight, thus rendering the operation of reciprocating a head or other device less tiresome.
The invention consists of the construction and arrangement of the mechanism hereinafter described, and briefly set forth in the claims.
Referring to the drawings, Figure 1 a central vertical section of the machine, with the sealing head in normal or position; Fig. 2 is a similar view showing the sealing head depressed.
Referring to the drawings, the numeral 1 designates the machine casing which is hollow and preferably tubular in form provided vwith the usual broadened base 2, which is surrounded near its upper end by a sleeve 3 of a sealing head l. Secured to the top of the casing is a hollow cap 5, the lower part of which is preferably internally threaded for the reception of threads of the upper part of the casing. The upper end of the cap is provided with an aperture 6 for the passage of a short threaded eye-bolt 7 carrying at its upper end, and outside of the cap, an adjusting nut 8. To the lower end of the bolt is attached the upper end 01' a coil spring J, the lower end of which terminates in a ihook 10 which passes through an aperture inl the lug 11, integral with a yoke 12. which Iyoke has journaled therein a toothed-wheel 13 which meshes with a rack bar 1% rigidly attached to the rear side ot' the casing. preferably by screws 15 as shown.
This wheel also meshes with a rack 16 rig idly secured to the reciprocating sealing head 4. the rack in this instance being preferably secured to the head by means of Specification of Letters Patent.

Serial No. 648,559.
screws 17. Screwed in the lower end of the yoke 12 is an operating rod 18 which extends to the bottom of the machine where it is pivotally secured to a treadle 19 by a transverse pin 20. The rear end of the treadle is secured tothe base of the machine by a transverse pin 22 and the "Forward end of the treadle extends out of the base through a slot 23 and is provided on its outer end with a. foot-engaging piece 24.
The casing is provided with a narrow slot 4 1 through which the rack 16 extends and presents its teeth for engagement with the teeth of the wheel 13. The downward movement of the sealing head is limited by the lower end of the slot 14;.
Secured to the machine casing at a suitable distance below the sealing head is an adjustable bottle support provided with a which will obviously, through the medium of the toothed wheel 13 and racks 1 1 and 16 depress the sealing head, against the'resistance or influence of the spring 9. When the treadleis released, the spring 9 will restore the sealing head to its normal or raised position. The gearing between the wheel and racks is such that a very short movement of the treadle will depress the head for its entire stroke.
Having thus described my invention. what T claim is:
1. in a machine, a reciprocatory member provided with a rack bar; a fixed rack-bar. a spring-restrained member, a toothedwheel carried by said member and adapted to engage the rack-bars, and means for operating the spring-restrained member to cause the downward movement of the reciprocatory member.
2. In a machine, a reciprocatory member provided with a rack-bar; a fixed rack-bar; a spring-restrained yoke, atoothed-wheel jouinaledin the yoke and adapted to, engage the rack-bars, and means for operating said yoke to c ause'thedownward movement of the reciprocatory member.
3. In a machine, ZL-IBCIPI'OCQCOIY member provided with a rack-bar; a fixed rack-bar; .E: a spring-restrained yoke, a toothed-wheel journziledin the yoke vand adapted to engage the retclg-bars; .arod 'conne'eted with said yoke, and means for operating saidrod yoke to cause the downward movement of the same and thereby the reciprocatory memi. ber. 'In testimony whereof I afiix my signature in presence of two witnesses.
