TIP-FORMING DEVICE FOR BILLIARD CUES AND THE LIKE.

Application filed August 26, 1915.

To all whom it may concern:

Be it known that I, MARTIN BOHLIG, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented new and useful Improvements in Tip-Forming Devices for Billiard-Cues and the like, of which the following is a specification.

My invention relates to improvements in tip forming devices for billiard cues of the class illustrated and described in Letters Patent No. 1,123,472 issued to me on Jan. 5,1915.

ts object is to provide improvements in tools of this kind having cutting means and gripping and centering devices for securing a billiard cue in position with relation to the cutting means, together with improved feeding mechanism, adapted to cause the cutting means to trim the cue positively and uniformly and also to automatically control said means so as to limit and finish the out.

My invent-ion also includes novel features of construction which will be more fully hereinafter described and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my improved device; Fig. 2 is a longitudinal central sectional view thereof partly broken away; Fig. 3 is a fragmentary sectional view taken on the line 33 of Fig. l and Figs. 4 and 5 are detail plan views of the gearing constituting a part of the feeding mechanism.

As illustrated in the drawings, my invention comprises generally a base A, a carriage B slidable on said base, a cutting head C revoluble on the carriage and feeding mechanism D for moving the carriage upon the base and securing the former with respect to the latter.

The base A consists of a circular crown plate 10, a circular base plate 11 and diametrically opposed posts 12 joining said plates 10'and 11. The crown plate lO is perforated at its center, the periphery of said perforation forming an annular beveled shoulder 13. The base plate 11 is formed with a central threaded bore 14. to

receive the externally threaded sleeve 15. An annular grip bearing 17 having a central bore and beveled internally at'its upper edge to form an annular shoulder 18 is supported upon the annular flange 19 within said Specification of Letters Yatent.

Serial No. 47,508.

sleeve. A. tubular grip 20 is formed with slots 21 therein to furnish a resilient clutch for the cue. Beveled annular heads 22 and 23 are provided near the ends of said grip, the head 22 being designed to bear against the beveled shoulder 13 of the crown plate 10, while the head 23 is adapted to impinge against the beveled annular shoulder 18 of the bearing 17. Said bearing 17 is advanced when the sleeve 15 is turned in one direction and forces the beveled heads 22 and 23 against said beveled shoulders, thus compressing the grip, and reverse revolution permits the return of said bearing and the expansion of the grip.

The carriage B, movable upon the base A, consists essentially of a circular bearing plate 24 formed with a central bearing 25 thereon, a guide ring 26 and diametrically opposed posts 27 joining the bearing plate and ring. These posts 27 are slidable longitudinally in the crown plate 10 of the-base A and said guide ring 26 is perforated to slidably receive the posts 12 of said base.

The head C includes a hollow plug 28,'and a blade holder 29. The plug 28 threaded externally at its upper end is journaled in the bearing 25 of the carriage B and is provided at its lower end with an annular flange 30 separated from said bearing 2d by a series of ball bearings 31, which receive the end thrust of the head C. A collar 32, constituting a part of the feeding mechanism D, hereinafter described, is screwed upon the threaded end of the plug 28. The blade holder 29 is a centrally perforated disk provided with a dependent, internally threaded extension 33, which is screwed upon the sleeve 28 against the collar 32. Said disk is formed with a groove 3 1'to receive a cutting blade 35 of suitable design and is'supplied with a thumb nut 36 to secure said blade. A handle 37 attached to the lower side of the blade holder 29 provides means for turning the head C.

Improved mechanism D positively and uniformly moves the carriage B upon the base A and also automatically limits such movement. This mechanism comprises essentially the toothed collar 32 above mentioned, a gear wheel 38, arranged to mesh with said toothed collar, a screw 39, on the carriage B, upon which said gear wheel is mounted, an arm 10 pivoted on the base A and supplied with a threaded bearing 41 to engage said screw, and a guide lever 42 on the carriage B to slidably support said arm 40 in engagement with said screw and to secure the carriage wlth respect to the base.

'The collar 32 is preferably supplied with a,

single rounded tooth 32 projecting from the periphery thereof, which is indented or cut away on both sides of said tooth as clearly shown in Figs. 4 and 5. The gear wheel 38 is formed with radial notches 43 to engage the tooth 32 (see Fig. 4) and portions 44 of the periphery of said plate between said notches are concave to lit against the periph- V ery of the collar 32 (see Fig. 5).

each revolution of the head C, the tooth 32 Upon meshes with a notch 43 in the gear wheel 38 and turns said wheel a partial revolution. During the interval when the tooth 42 is disengaged from the gear wheel 38, the periphery of the collar 32 rests against one of the concave segments 44 ofsaid wheel and sescrew 39.

crown plate 10 bears against the end of the arranged so that when the lever 42 is tilted beneath the arm said lever (which is preferarm40, upon which said bearing 41 is secured, and operates to swing said arm outward and disengage the bearing from thescrew 39. The lever 42 pivoted upon the I carriage B is formed with a central graduated slide 48 and depressions 49 at the ends of said slide. This lever is adapted'to swing beneath the end of the arm 40 opposite the threaded bearing 41 and connect the slide 48 thereon With the arm 40 to tilt said arnr against the action of the spring 47 and mesh said threaded bearing 41 with the screw 39.

The arm 40 is beveled at 50 and notched at '51 as shown in Fig. 3. The lever 42 impinges against the beveled portion 50 in tilting the arm and is slidably retained beneath said arm by the notch 51 which receives said. I provide a plunger 52 seated in a lever. bore '53 in the crown plate 10 to brace and hold the lever 42 at the point of engagement with the arm 40. A coiled spring 54 compressed behind the plunger yieldingly forces it outward and a pin 55 in the crown plate passing through a notch 56 in said plunger limits its longitudinal movements. Said plunger 52 is rounded at its outer end and is ably round in cross section) will depress the plungerand pass slightly beyond the aXis thereof before entering the notch 51 in the arm 40.- By this arrangement, it will be seen that the lever 42 is yieldingly held beted to tilt by the actionof the spring 47, thus, 7

disengaging the bearing 41 from the screw 39. The arm 40 'fits snugly into the depressions 49 and rigidly secures the carriage B with i'espectto the base.

In use, the carriage B is set with respect to the. base A to obtainthe desired cut by first swinging the lever 42 from beneath the arm 40, then sliding said carriage upon said base to the desired point and finally returning said lever to position beneath the arm. The one or other object is secured within the grip by tightening the "sleeve '15 and the head 0 is turned to cut the cue. Upon each revolution of the head 0 the screw 39 is' turned a partial revolution and the carriage is advanced a step one way or the'other according to the direction in which the head C is turned. During the movement of the i carriage Brupon the base A, the lever 42,

passes beneath the arm 40, the slide48 thereon supporting the end of said arm against .the action of the spring 47; When either of the depressions 49 reach the. arm 40, said arm tilts from the slide 48 intothe depres= sion, thus rendering the feeding mechanism D inoperative and firmly holding .thecarriage B in engagement with the base A.- Contlnued rotation of the head accurately finishes the out upon the one, which may I then be removed from the device by loosening the sleeve 15.
