UNITED` STATES PATENT OEErcE.
BENEDICT HUTZEL, on NEW YORK, N. Y.
SPECIFICATION forming part of Letters Patent No.1608,457, dated August 2, 18984. f
Application filed September 11, 1897. Serial No. 651,361. (No model.)
To all whom it may concern.
Be it known that I, BENEDICT HUTZEL, a citizen of the United States, and a resident of New York, (Brooklym) county of Kings, and
State of New York, have invented certain new andy useful Improvements in Billiard-Cues, of which the following is' afull, clear, and exact specication, reference being had tothe accompanying drawing, showing a sectional 1o viewr of the butt-end of my improved billiardcue to which my invention is applied.
My invention relates to utensils for playing billiards; and it consists of a billiard-cue provided with an adjustable ballast-weight applied to it in such manner that the quantity and also the position of the weight can be changed and that the strike of the cue is rendered vspringy or elastic.
It is usual to provide billiard-cues with a ballast-weight, mostly lled in in the buttend thereof, There is, however, a diversity of opinion as to where this weight should be located and what its quantity should be. For this reason every billiard-table is equipped 2 5 with a large number of cues varying in these respects. Y l
The object of my invention is to obviate the necessity of providing so many cues and is attained in the following manner, illustrated in the accompanying drawing, showing a longitudinal view of the butt-end of a billiard-cue constructed in accordance with my invention.
The lower end ofthe stem A of myimproved cue is provided with a bore a, slightly ta- 3 5 pered toward its end and screw-threaded at` its mouth, the screw-thread matching that provided on the shouldered end i of the butt l). Butt b is also provided with a bore b',
which is narrower at its mouth and screw- 40 threaded, the screw thread extending Yfor about an inch into the bore and corresponding with that of the rod c. Beyondl the screwthreaded part the bore b is slightly wider to permit the end of the rod o to pass in freely.
b and is secured in its position by lock-nut c. Its other end is screwed into the stopper-nut g, snugly fitted into the bore'l a, and preferably packed with a rubber band g', holding 5o it irmly within the bore a and preventing Rod c is screwed into the bore of the butt also its turning when the' rod c is screwed into it.
.The screw-thread in the nut g and on the end of the rod c (passing through this screwnut) is of the same pitch as the screw-thread in the mouth of the bore a and upon the shoulder fi of the butt to facilitate the screwing in of the butt. Nut g is stuck firmly in the .bore a when the butt-end of the cue is inserted, whereas rod c is lixed by the nut h 6o and turns with the butt when its shoulder z' is screwed into the end of the cue.
To avoid displacement of the nut g or twisting of the rod c, it must be screwed through the nut g at the same rate as the shouldered end z' of the butt into the end of the cue.
Springs f and f are preferably fastened with one end to washers e ande' and with the other to set-nuts h and h', respectively, to 7o keep them free from contact with the rod c or with the stem of the cue. Weights d are helden the rods c between washers e and e' by springs f and f. They are preferably made ofy lead` in the shape of collars fitted upon the rod c, of uniform weight, and their number varies according to how heavy the cue is to be made.
The force of momentum depends largely on the quantityrof the mass moved, and conse- 8o quently the larger the number of weights set 'on the rod c the greater the force produced by Athe stroke of the cue.4
If the ballast be immovable, the stroke would be hard. In my improved cue the momentum imparted to the weight by the motion of the cue in the act of striking a ball and tending to shift vit in the direction of the motion of the cue is made to act upon the recoil-spring f pressing against it. The force compresses the spring 9o more or less, according to the force of the stroke, and when the momentum has spent itself this spring reacts against the weightl and returns it automatically to its normal position.
,Springs f and f must be adjusted (more or less compressed) according to the quantity of 'weights inserted between them, and their power of resistance the more increased the harder a stroke required.
The tension of the roo springs is adjusted by increasing or reducing the spaces between the washers e and e'and set-nuts hand 7L. In eonneetiontherewith the length of rod c is regulated as the number of the weights d is Varied.
The position of the weights d can be changed for about one-halt ol' the length of the rod c. This will be found su iiieient tor all ordinary purposes.
I claim as myinvention and desire to secure by Letters Patentl. A billiard-cue comprising` a stem provided with an open bore screw-thread ed on its lower end, a butt, having a screw-threaded shoulder screwed into the bore oi' the stem, and abore concentrieal with the bore ot the stem and serew -threaded at its mouth, a screw-threaded rod screwed in the bore et the buttand projecting into the bore ei the stein, a lock-nut screwed on the rod adjoining the shouldered end of the butt and securing` the rod in its position, a screw-threaded stop-nut tilted into the bore olf the stem and provided with frietional packing', set-nuts and washers set on the rod between the nui s, recoil-springs set between the washers and the set-nuts :ind
tending to press the washers together, and perforated weights slid on the rod between the washers and held together and also in adjusted position by the pressure of the springs.
2. rl`he combinationwithabilliard-euecolnposed ol.' two er more parts, one havingabore provided with a screw-thread in its lower end and the other a screw-threaded shoulder adapted to be screwed into the bore of the preeeding part, of a screw-threaded rod seeured in the shouldered part eoncentrieally with the bore, a nut fixed in the bore and screwed on the opposite end of the rod, recoil-springs set between the nut and the base of the sei-ew, washers slid on the rod between the springs, and weights set between the washers and held in position by the springs.
In witness that I claim the improvements described in the foregoing specification I have signed my name in the presence of two subseribi ng witnesses.
