- To all whom it may concern.'

Be it known that' I, OLAF E.' GISET, a citizen of the United States, and resident of the borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in GolffScore Registers, of which the n the cylindrical supporting block `and certain following is a speciication.

This invention relates to improvements in golf score registers, and has for its objects to provide a device for registering the number of strokes for each hole of a course having a numeral wheel for each hole and a single operating means for all of said wheels; to provide a register of compact construction adapted to be carried on a players wrist in the manner of a wrist watch; to provide a golf score register having a simple manually actuated registerlwheel-operating lmechanism manually settable to act on a series of numeral wheels successively and only capable of wheel-operating movement when in operative relation with a numeral wheel; and to provide a golil score register having'a general operator rotatable in oney direction only to progressively advance a register-wheel stepping device from wheel to wheel and reciprocable to actuate said stepping device only' when said stepping device is in operative relation with a numeral wheel, said register having numeral wheel zero-setting means operable by a rotary movement ot the general operator in th'e direction ot its stepping device advancing movement.

To the foregoing and other ends which will hereinafter appear, the invention convsists in the features ol construction, ar-

rangements ot parts, and combinations'of devices set forth in the following descrip! tion and particularly pointed out in the appended claims.

The working parts of the register are mounted on a shortl cylindrical metal block 1 which is removably held .in an enclosing case of approximately the size and appearance of an ordinary wrist watch casing. The casing comprises a main annular central section 2 to the opposite ends of which y two rings or bezel sections 3 and 4e are detachably held,.said bezels carrying glass disks or crystals 5 and`6 respectively. The casing section 2 is formed with a pair of oppositely disposed attachment loop members 7 to which the usual straps for fasteninO' the device u non the users Wrist ma be attached. p The block 1 is formed with a shoulder 8 held against an internal shouldery near the forward end of casing section 2 by a shoulder 9 on the rear bezel 4, a plurality ot studs 10 projecting from the shoulder 8 tion 2 to'position the block in the casing.

The block 1 is provided with an axial cylindrical bore 11- extending from the rear tace ot the block to the inner end of a cenengaging in sockets in the shoulder on sectral cavity or recess 12 formed in the front `face of the block. The hub 13 of a bevel gear 14 is journalled in the bore 11, said gear being housed in the reduced inner end of recess 12 with its teeth lfacing the louter end of the recess. A metal plate 15 is. rigidlyl held by suitable screws against the annular shoulder 16 in recess 12, said plate having an outwardly extending lug 17 formed withv a bearing aperture 18 for one end of" the hub of a bevel pinion 19. The pinion 19 meshes with gear 14 and the upper end of of the pinion hub extends close to the circular wall of recess 12 which is preferably flattened at 20 to form an abutment for the end of the pinion hub while shoulder 1G is formed with a radial groove v21 to afford -clearance for the upper end of the hub.

vThe hubpol pinion 19 has an axial passage 22 therethrough which is square in crosssection, said passagev registering with a cylindrical passage 23 extending from the outer edge of block 1 te recess 12 radially of the axis of gear 14. The rod-like general operator 24 of the register isv rotatably and slidably guided in passage 23 and resembles the stem of a watch in appearance having a grooved crown or finger knob 24:"L at its upper end. The upper portion of operator rod 24 is cylindrical so as to revolve and reciprecate in the guide passage `23, while the lower portion of said rod is square vin cioss section so it may slide through the passage 22 in pinion 19 and will drive said pinion when the rod is rotated.v The extent of re- `ciprocable movement of the general operator is limited by engagement of shoulders 25 and 26 thereonwith a set screw 27 tapped through block linto passage 23. The cas- .ing section 2 is formed with a flanged 'guide opening 28 for the \general'-operator 24.

A dislelike metal dial plate 29 is held against the flat front face of block -1 by a pair oit screws 30, the outer face of said plate being spaced from front crystal 5'.

y The block 1 is provided with an annular recess 31 in its rear face concentric with the gear hub bearing aperture 11, and said block is provided around its outer edge with an arcuate series of eighteen. slotsr 32 extending inwardly from the outer edge 'of the block and terminating a short distance within the outer annular wall of recess 31. The slots 32 lie in planes radiating from the axis of block 1 and oblique to the planes of 'the front and rear faces of the block. The first and last slots of the arcuate seriesi are spaced apart a substantial distance and the ends of these two slots'at the front face of block 1 are located at opposite sides of the general operator 24. The slots from the beginning to the end of the series are spaced an equalnumber of degrees apart and are substantially closer together than the two end slots of Athe series. Dial plate 29 is provided witl" an arcuate series of eighteen sight apertures 33 registering with the forward ends oi slots 32 and also has printed or painted thereon the designation O as shown at 34 between the two end apertures in register with the relatively wide segment of the block between the two end slots of the series of slots 32. The apertures 33 are numbered 1 to 18 from right to left, the designating numerals 35 being printed, painted or sten'cilcd on the outer face of dial plate 29 inside of the series of apertures.

A. frustoconical numeral. or register wheel 36 is rotatably mounted in each slot 32,.and each wheel 3G has printed or stamped on its periphery the ten arabic numerals O to 9, inclusive, as indicated at 37, which numerals are successively visible through apertures 33 in the dial plate when the wheels are rotated. Each wheel is journalled on the inner nonthreaded end portion of a bearing screw 38. Each screw l 38 for one 'wheel passes through the web or segment of the block in advance ol' the slot in which thev wheel is mounted and is threaded iii said .web with the head of the screw countersunk in the web. rlhe screws pass across the slots at right angles to the side walls of the slots and obliquely to the plane of the front face of the block, and the wheels are mounted on the screws with the smaller ends oit the wheels nearer the heads of the screws, i. e. the small ends el the wheels face around the series in counterclockwise direction. The peripheral part' of each wheel opposite the sight openings is thus always substantially parallel with the plane of the dial plate. The oblique arrangement of the slots permits convenient assembly of the -wheels therein, and permits the use of thin rusto-conical wheels having a relativelybroad periphery so that relatively large numerals inay be provided on small thin wheels which can be arranged in a block et small diamrer and littlev thickness. One wall of cach slot at the front face of the block is provided with a diagonal groove 39 in line with the screw hole 40 for screw 38 through thel opposite wall to aiiford clearance for the shank of a screw-driver and to ailord clearance :For the long screw in inserting and removing the screws and wheels.

Each numeral wheel has a bearing sleeve 41 surrounding its bearing screw 38, one end of the sleeve being headed against the larger end of the wheel and the other end being headed oi pcened down against the outer face of a heart-shaped cam plate 42 held flat against movement relatively to wheel 3G by said headed sleeve and by a fastening screw 43 passing through the cam into the wheel. The larger end of the wheel 3G is formed with a circulargroove 45 in which llO is seated a resilient metal washer 44 humpedor bowed at two diametrically opposite points as shown at 44a so that said washer yieldably and frictionally engagesv one face of the wheel and the adjacent wall lof the slot in which the wheel is mounted to thus hold the wheel against accidental rotation.

All of the numeral wheels are adapted to be rotatedstepA by step byasingle wheel stepping pawl movable by successive rotary movements of the general operator 24 into operative relation with the vsuccessive numeral wheels and also operable repeatedly by successive reciprocable movements of the general operator to rotate each wheel the desired number of steps to register the strokes required to cup the ball at each hole. The numeral wheel rotating push-pawl 46 is pivotally held by a screw 47 to one end of a lever 48 which is p ivotally held intermediate its ends to a rotatable metal plate 49 by means cfa pivot screw 50. A spring 51 secured to lever 48 normally presses the nose of pawl 46 against the inner iiatwall of recess 31 in block 1. 'A stop 52 on lever 48 cooperates with the edge portion 53 of plate 49 to limit the movement of lever 48 in one direction, said lever being movable in the opposite direction by a pull-pawl 54 pivotally connected to one end of the lever at 55 and having a laterally extending pin or nosepiece 54a adapted to` ride around the periphery of an oscillatory notched ring 56 and snap successively into the eighteen notches 57 in said ring as the pawl 46 is brought successively into operative relation with the i eighteen numeral wheels 36. The ree end of pull-pawl 54 is normally urged in a direction to press pin 54a into a notch in ring 56 by means of a spring 5 7-which -is fixed to the pawl at 58 and bears against stop 52 at its Jfree end.

.The inner circular wall of the annular recess 31 is stepped to provide a circular shoulder 59 forming a bearing for the notched oscillatory ring 56 and a circular shoulder 60 of less diameter on which is seated a fixed notched ring 61 having nineteen notches 62 in its periphery. A resilient check-pawl 63 rigidly affixed to thevplate 49 at 64 has a nose adapted to ride aroundthe periphery of ring 61 and snap successively in each of the 19 notches to hold the plate 49 against accidental turning when pawl 46 is brought in cooperative relation. with either numeral wheel or is brought to the wide 0 space between the No. 1 and No. 18 numeral wheels. block 1 by two screws 69 and a centering stud which engages in a socket 70 in block 1.

Pawl 63 extends in a direction opposite to that in which the plate 49 turns and the edge of each notch 62 engaged by the leading edge of the pawl nose is inclined to per-y rotate ,therewith Ring 61 is rigidly held tomit the nose to ride upout of the notch when the plate is rotated in`a clockwise direction, while the other edge of eachnotch is in a radial plane so that engagement of the nose of the pawl therewith will` prevent reverse rotation of plate 49. The notches 57 in ring 56 are similarly shaped, so that pin 54a on pull pawl 54 will ride out of each notch as the plate 49 is rotated step by step, while said pawl will be pulled endwise when ring 56 is oscillated from its normal position by engagement of the radial edge of the notch with the pin. y

Ring 56 has a forwardly extending pin 65 rigidly held thereto, and said pin projects through an'arcuate slot 66 in block 1 and a registering notch 71 in plate 15 and engages under the free end of a lever 67 which extends across the outer face oi' plate 15 and is pivotally held to the plate at its opposite end by a pivot screw 68. The ring 56 is normally rocked in a counter-clockwise direction to hold pin 65 at the upper ends of slot 66 and notch 71 by means of an arcuate spring 72 seated in an annular groove 73 in block 1 at the inner end' of recess 12. Spring 72 is secured to the bleek at one end by a screw `74 and has a hook-like free end 75 extending through a radial groove 76 in block 1 to slot 66 and bent around pin 65 on ring 56. An indicator hand 77 -isj fixed on the forward end of a shaft 7 8 which extends through the Ahub 18 of gear 14 and is locked to the hub to rotate therewith by means of a stud 79 which engages in a socket in the hub and is carried by a flange 80 on the shaft. A screw- 81 threaded in a socket in the rear end of shaft 78 holds plate-49 against the rear end of hub 13 and a pair of studs 82 on said plate engage in sockets 83 in the rear end of lsaid hub, thus locking the plate to the gear 14 to The lever 67 is adapted to be rocked against the tension of spring 72 by an inward thrust on the general operator 24, the inner end of which operator engages the free end of a lever 84 pivoted at 85 to plate 15 and interposed between lever 67 and the inner end 'of the operator shaft 24. The free end of leve'r 84 normally engages under lug 17 on plate 15, being held up by the lever 67 and spring 72. A guide arm 86 held to plate 15 overlies the front side of lever 67. The lever84 is provided with a rearwardly extending projection or stud 87 the inner end of which is normally located between the teeth of' gear 14 and 'a radially slotted annular flange 88 on the front `tace of said gear. The iange 88 is provided with an arcuate series of eighteen equally-spaced slots 89 and a relatively long non-slotted portion between the first and last slots of tl= series. lhen locking pawl 63 engages i one of ,eighteen consecutive notches in ring 61 the free end ot. hand or pointer-.77 o`n shaft- 7 S is opposite one of the apertuies- 33 in the dial p late., pin S7 is opposite a slot 89 in flange v8S, pawl 46 is in cooperative relation with the number wheel to which the hand points, and pin 54a on'pawl 54 is engaged in one of the eighteen notches in oscillating ring 56. lVlien the pawl 63 engages in the nineteenth notch in ring 61 the pointer registers with the 0 character on the dial, pin 37 on lever 64 is opposite the relatively long non-slotted part' of )flange 88, and pawl 46` is opposite the.v wide non-slotted part of block 1 between the No. 1 and No. 18 numeral wheels. In this position not only is pawl 46 out of cooperative relation with any numeral wheel, the general operator 24 cannot be pressed inward because pin 87 engages tlange 88.

Slots 69 only register with pin 87 when.

pawl 63 engages a notch in ring 61 and pawl 46 is in position to act on a numeral wheel. The use i.' cannot therefore make' a false or ineffective reciprocation oit' the general operator when the hand is at 0 or pawl 46 is between any of the numeral. wheels or pin'54 on pawl 54 is out ot a notch in ring 56.

The numeral wheels are rotatable to zero position, i. e. to a position in 4which the character O7 thereon is in register With the sight openings 33 in the dial7 by means ot zero-setting levers 90 pivotally held by Screws 91 against the side walls of slots 32 adjacent the smaller ends of the frustoconical numeral wheels. Block 1 at its rear face is provided with diagonal grooves 92 in that side Wall of each slot 32 opposite the wall against which thelever 90 in said slot is held, which grooves register withthe screw holes 93 tor screws 91 and permit ready assembly of levers 90 in the slots by means et a screw-driver. The 'forward ends of levers 90 rest on the peripheries of the heart cams 42 which are fixed ont-he smaller ends ot' the numeral wheels, while the rear ends ot said levers project slightly beyond the. rear :tace oit block 1 between the periphery of the block and recess 31 in the path et the 'l-r'ee end of a resilient zerosetting arm 94. Arm 94 is held at one end in a groove 95 in plate 49 by a screw 96 so as to rotate with said plate and the free end of said arm projects beyond the edge of said plate and rides around the rear `face of the block 1 so as to successively engage the rear ends ot levers 90. Said arm upon engaging a. lever 99 tirst rocks the 'Forward end ot' the lever toward the axis of the adjacent numeral wheel, thus exerting pressure on the periphery of the heart cam and causing the numeral wheel to rotate until the low point ot the cani is under the forward end of the lever at which time the 0 character on the wheel registers with the adjacent sight opening in the dial and lever 90 is locked but' against further rocking movement (see Fig. 16). Continued rotation of plate 49 in clockwise Adirection will cause arm 94. to yield sufficiently to pass under the lever 90 thus rocked and pass on to the next lever. It will be obvious that by rotating the general operator 24 sutlciently to cause gears 19 and 14 to rotate late 49and dial hand 77 through one revo ution from O 7 position all the numeral Wheels will be set at Zero where they will be held by the friction washers 44.

To. register the score as a game is played operator- 24 is rotated slightly until hand 77 registers with the sight opening numbere'd 1 on the dial. This carries pin 54 on pawl 54 into the iirst of the series of eighteen notches 57 in the oscillating ring 56 and earriespawl 46 in position to engage in the ten equally spaced notches` 36 in the periphery oit the first. numeral wheel 36, said notches being formed in the truste-conical numeral wheels at the larger ends thereof. lVh ii the numeral wheels are at zero one ol these notches stands just outside of the liront wall of recess 31 against whiclrpawl 46 is held by spring 5l as 'before described while the next adjacentnotch stands just within the outer circular wall of said recess in the path of the free end`ornose portion of a resilient check pawl 97 held at 98 to plate 49. Pawl 97 is so located on plate 49 that it only en gages the notched edge of a numeral Wheel after arm 94 has passed lever 90 and when. pawl 46 is in operative relation ,with the.

wheel. It will thus be apparent that paWl 97 will not interfere with rotation of the numeral wheels in either direction by the resetting lever 90, and that in case anumeral rwheel should have shifted slightly the act of bringing the stepping means in operative relation with the;l wheel will restore the wheel to its exact normal position before the. check pawl 97 reaches the wheel and rides into the notch adjacent the outer circular wall of recess 31. The first numeral wheel may now be rotated one notch space for each stroke made by a laye-r in making the viirst hole of the course y pressing general operator 24 inwardly once for each stroke. The pawl 97 is designed to prevent accidental reverse rotation of the` numeral wheels by pawl 46 on its return stroke.- The depression of operator 24 rocks levers 84 and 67 and oscillates ring 56 against the action of spring 72 causing said ring to pull on pawl 54 and rock pawl 46 Jfrom the position shown iii Fig. 1() to that shown in Figs. 11, 12 and 13, thus rotating the numeral wheel oneste-p. Upon release of the operator spring 72 restores the parts, pin 54l on pawl 54 being held in the. irst notch in ring, 56 by spring 571l and said pawl 54 moving back to normal vposition with respect to plate 49 as ring 56 Lal ing pawl 46` away from the numeral wheel.

After the player holes out at Nol 1 he again rotates operator 24 until hand 77 registers with the No. 2 sight opening, thereby carrying pin 54a on pawl 54 into the second notch of ring 56 and carrying pawls 46 and 97 into cooperative relation with the second numeral wheel. The score for the second hole may now be registered. The operations above describedare repeated until the round of the course is completed, whereupon the wheels may be restored to zero as above described. The high point of the heart cam on each wheel is arranged to` pass under the forward end ofthe adjacent lever 90 as the space on the wheel between the characters 5 and 6 is passing the sight o ening. Lever 90 will therefore rotate t e wheel in either direction to zero dependent uponI the score registered by the wheel. It is thus'neoessa-ry to rotate a wheel `only approximately one-half a revolution at the most to set it at Zero. An easy and ranid zero-setting operation is thus' obtained. Abutments 52 and 53 lock the ha wl and lever stepping means 54-48-46 to the plate 49 so as to cam pin 54a out of one notch in ring 56 and carry it around to thenext notch in said ring during the step bystep rotation of the plate. The resilient pawl 97 normally flexes forward through the opening 99 in plate 49 against a limiting stop 100y secured to the front face of plate 49.
