Fig. 51s a fragmentary sectional view takenon line-5-5'of Fig. "1.

Fig. 6 is a cross sectional view taken substantially on line 66 of Fig.2.

My invention proper consists of a trackindicated in its-entirety by the-reference-numeral A and a-carrier B to which a club C is attached. This carrier moves along the track A and guides the club C'in the desired path. These various parts will now be described'in'detail.

In the use of my invention 'an ordinary putter such as indicated at A'may be employed which comprises a shaft lflshaving a putter head ll secured to saidshaft in-offset' relation withrespect thereto. The'putter head II is provided with a face l2 arranged at a slight angle with respect to the axis of the shaft and with-asole l3 issuing angularly from the face l2' and forming an acute angle with said face. The back of the club head is indicated'by the reference numeral 14 and is 'more nearly parallel with'the axis of the shaft forming in conjunction with the face I2 a wedge-likestructure-best shown in Fig. 5. The invention is particularly adapted for use in conjunction with a'club such as described, though it canreadily be comprehended that the supporting structuremay-be modified to support other types of putters if 'found-desirable.

The track A consists of two'rails l5 and [B which are constructed of bar material'suchas known'in the trade as flatwire. Theserails are bent to give'the'said-railsthe desired curvature and are connectedtogetherat their ends through two' end membersl'l and I8. "Froman' inspection of "Fig. 3 it'will benoted' that the rails l5 and 16 are providedwith averticalarc which is designated bythereference numeral i9 so that when the "carriage B follows 'along' the 'said' rails, the club head is directed to swing throughapivot located substantially at the wrists of the player. The rails [Sand I6 are" further "constructed to provide :a horizontal arc designated by the reference numeral 2| in Fig. 2 which causes the club headto swing about theplayer in'theback swing so as to'produce a "stroke whichis exceedingly natural for theplayer and which will produce the best results.

"Theendmembers'll and: F8 are constructed'of bar material similar .topthe railsl5'and IS. The end memberl'l is bent toform a cross piece 22 and is'further'bentto provide two legs 23 and 24 depending therefrom. The ends of the rails l5 and are secured to the legs 23 and 24 through rivets 25. The lower ends of the legs 23 and 24 are bent inwardly to provide feet 25 and El which rest upon the surface on which the putting device is placed. The end member i8 is similarly constructed with a cross bar 28, legs 3! and 32 and feet 33 and 35, which end member is attached to the other ends of the rails 55 and 95 through rivets 35- and functions in identically the same manner as the end member H. By means of the two end members i? and E8 the device can be placed upon the putting surface and when so disposed is at the proper position to guide the club as will hereinafter be more fully explained.

The carrier B consists of a carriage 55 which has attached to it a holder 37 in which the club C is mounted. The carriage 35 travels over the upper edges 33 and 35 of the rails i 5 and i5 and serves to guide the club head for movement along the desired path.

Y The carriage 35 consists of a frame 4| of H shape which is constructed with 7 two parallel frame-members 3-2 and 53 and a cross frame member 54 connected to the parallel frame members intermediate the ends thereof. The various frame members are preferably constructed of angles as shown in Figs. 4, 5 and 6. The angles are secured together through-rivets which extend through the flanges of said angles and through tongues 45 bent outwardly therefrom. By means of thisconstruction a composite structure is formed which is extremely light in weight and; which is rigid and sturdy in construction.

At the ends; of the parallel frame members 52 and+23-are=journaled supporting wheels 41, 48, 55 and 55 which are rotatably mounted in a manner to be presently described in detail. Inasmuch as all of these wheels are identical in construction, only the wheel 59 will be described in-detaih This wheel is best shown in Fig. 6 and consists'oftwo discs 52 and 53 which are dish-shaped in form. Adjacent these discs are disposed two fibre liners 55 and 55 which are also dish-shaped and which are secured to said discs 52 and 53 through .lips 55 and 5'! turned over from the marginal edges of said discs. The two discs and 53 are mounted upon a hub 58 which is constructed with shoulders 55 and 6D and by means of which the said discs are secured together. Between the two discs 52 and 53 is provided a drum I59 which is constructed of tubing cut to the desired length. Drum E59 is provided with lugs 61 which issue outwardly from the ends of the same and which pass through the liners 55 and 55 as Well asthe discs 52 and 53, and which" are riveted over upon the outer surface of said discs to hold thedrum attached to the discs and to form a rigid and substantial wheel construction. A rubber tire 52 encircles the drum 59 and forms a wearing surface for engagement with the upperedges .58 and 39 of the rails I5 and i5.

llhe wheel 49 is supported in the following manner: Threaded into the vertical flange 63 of thef'rame member 53 is a bushing 54. This bushing is tapped to receive the threaded end 65 of a headed screw which serves as a trunnion on which the wheel 59 is journaled through its hub 58. Bushing'fit is held in adjusted position with respect to the flange 53 of frame member 43 through'a lock nut 51. Upon the threaded end 55 of screw 55 is another look nut 68 which holds said trunnion in adjusted position. By means of this construction the wheel may be adjusted axially with respect to the frame of carriage 35 so as to cause said wheel to properly ride upon the rails 15 and it. As previously stated, the wheels M, 38 and 5B are constructed similar to the wheel 48 and the said wheels are journaled in like manner upon suitable trunnions the same as those used for the journaling of the wheel 49.

The holder 3'2 consists of two hangers H and 52 which are connected together through a cross bar 65. The two hangers H and 12 are preferably formed of strips of metal bent to provide depending portions l3 and M and upturned portions 75 and 75 connected to the depending portions through connecting portions 71 and T8. The upturned portions 75 and it serve as jaws against which the face E2 of the putter is urged and are sufficiently spaced from the depending portions to freely receive the head of the putter. The cross bar 69 is attached to the depending portions of said hangers by riveting or otherwise at a locality opposite the back [4 of the club. The ends of the depending portions 13 and '14 are each given a quarter twist to" provide two ears 8! and 82 by means of'which the hangers may be hung from the carriage 36.

For the purpose of holding the club in position within the club-f holder, a set screw 19 is utilized which is threaded into the cross bar 69 and which engages the back of the club as shown in Fig. 4. It will be found that all putters'have a straight face. For this'reason the face of the club is urged against the upstanding portions 15 and '56 which properly positions the club with respect to the club holder. It hence is immaterial what shape the back of the club has as far as the positioning of the club with respect to the holder is concerned. Due' to the wedgeshape of the club head of the particular club illustrated, the club is readily held in position within the holder and disengagement prevented, without the necessity of screwing the screw 19 down tight.

The two hangers ll and 72 are pivoted to a bracket 83 by means of a pintle 84 which extends through the two ears Bi and 82 and through two other ears E55 and 35 formed on the ends of said bracket. The pintle 84 extends in a direction substantially parallel with the cross frame member 54 of carriage 36 and permits the club head ii to follow along the prescribed course without interference withthe travelof the various wheels of the carriage 3 along the track A. The bracket 83 is pivoted to the cross frame member 54 through a bolt 8i, which bolt extends through said bracket and the frame member 44 and which is threaded into said frame member and secured thereto through a lock nut 38 screwed upon the end of said bolt. By means of this construction the player may adjust the club to fit his particular stature and address without causing the wheels of the carriage to depart from the rails along which they travel, permitting the player to handle the club in an extremely simple and practical manner. i

For supporting the ball while the same is being projected by the putting device, a plate-like spacer member 89 is employed which is disposed between the two rails i5 and i5 and which holds said rails at the centers thereof in proper spaced relation. This plate-like member is provided with a base portion .5! which lies in the plane of the feet 25, 27, 33 and 3 5 of the end members H and i8. This plate-like member is further constructed with two upturned flanges 92 and '931'S6Cl1r6d to the inner surfaces of the rails l5 and l6 through rivets 94. At the proper location and upon the upper surface of the plate-like member-9i is provided a. depression 95 for supporting a ball in proper position to be propelled bythe putter. The position'of the ball when mounted in said depression is shown in dotted lines at 96, in Fig. 5. The holder 31 is so constructed that the portions 7'! and 1B of the hangers H and 12 clear the upper surface of the spacer member 89 when the carriage 36 is traveling along the rails I5 and I6. The depression 93 is so disposed that the ball contacts with the club head I! at the center of percussion of the club head so that the ball is'properly propelled. over the playing surf ace when the club is manipulated in the desired manner. 7

The-manner of using my invention is as follows: "The device may be used upon any type of putting green, either indoors or outdoors. When the device is to be used on a level surface the player takes the device "and places the same upon the putting green with the forward portion of the two rails. l5 and 56 parallel to the line extending between the center of the cup and the depression S5. The device may be situated at any distance from the cup which the player desires, the principle involved being the same for all lengths of putts. The player then attaches his putter to the deviceby placing the head H thereof within the spaces formed between the portions l5'and l3 and the portions 16 and M of the hangers H and 12. The club is lowered until the sole 53 thereof engages the portions TI and 73 of said hangers. Set screw 19 is next adjusted which brings the jaws i5 and 16 into engagement with the face I 2 of the club and which holds the club-properly attached to the support. The device is then ready for use. The player next takes his stance adjacent the rail l6 with his feet fairly close together and with his weight largely upon his left foot. Hethen adjusts himself until his head'is directly 'over the ball placed upon the depression 95. The player then next takes a grip of the club and may employxany desired approved'grip. The applicant has found that a firm grasp with all of the fingers of the right hand and with the thumb on the shaft and with the first threefingers of the left hand upon the shaft and the forefinger ofthe left hand overlapping the little. finger of the right hand and with the left thumb also upon the shaft produces splendid results. With the right forearm resting against the body of the player and with the left elbow 7 pointing in the direction of thecup, the arms are practically held immobile relative to the body of the player and the execution of the stroke greatly facilitated. Without movement of the body and 7 arms and mainly through the action of the wrists, the player swings the club rearwardly. This causes the carriage 36 to travel rearwardly along the two rails l5 and lfi-which causes the club head to follow along the desired path constitutingthe upswing of the stroke. The player then applies force to the club principally through the right hand carrying the club down to the ball and .propelling the ball off the depression 95 and along the playing surface on which the putting device is stationed. The player continues the movement of the club along the forwardportion of the track which constitutes thefollowthrough of the swing. As the club follows through, the hands of the "player leave the body slightly to permitof proper execution of this portion of the stroke. In the executionofv theputting stroke it is desirable that the putter be manipulated at a certain speed which is relativelyslow as compared to the maximum speed:with which it ispossible to swing the club. The weightof the'carriage and the friction of the wheels .upon the rails along which they travel helpxreduceithe :speed of the club head to the proper speed. The device is so designed that when thezplayer swings thejclub at a comfortable rate of speed :not requiring too much exertion, that the said club. head and carriage travel at approximately'the proper speed to procure the best results. While the carriage is traveling, the same takes apathsuchas is determined by the vertical are H! and the horizontal arc =2i of the edges 38 and39 of the two rails l5 and 6. The curvature of these arcs is determined through experi ment and is so designed as to cause the player to swing the club through the proper path and also in the proper direction to procure the desired results. By means of the curved back swing the player swings in a more natural and easy manner than would be the result were the back swing straight. When the stroke is properly executed, the carriage follows along the track. If, however,*it is improperly executed, the wheels are forced off the track and the player becomes readily aware of his error. In the first use of the device it frequently becomes difficult to cause the ball to travel more than a few feet. This is due to an attempt to accelerate the club and carriage too rapidly. When the movement is slowed down and the club is caused to sweep through the ball rather than to strike it, the ball travels in the proper manner. After the user has experimented with the device, the feel of the club in traveling over the prescribed .path is readily ascertained and he may attempt'to execute the same movement without the aid of the device. The applicant has made numerous tests and has found that pupils using the putting device learn very quickly to execute the movements in the prescribed manner and thereafter are able to reproduce them without appreciable effort. When it becomes desirable to practice on sloping surfaces, the device is adjusted to allow for the roll and the same procedure followed.

My invention is highly advantageous in that an-extremely simple and practical device is provided, whereby actual assistance may be given to pupils desiring to learn the correct method of putting. With my device the pupils favorite putter may be used and applied to the putting device, malnng it unnecessary to use a putter forming a part thereof. The device not only teaches the correct manner of executing the stroke, but causes the club to be swung through the proper path so as to procure the proper direction of the travel of the ball. In addition the device assists in teaching the pupil the proper timing of the stroke, thereby preventing striking the ball instead of sweeping through the ball as recommended by the professionals. The device offers no appreciable inconvenience to the player and is readily adjustable to variations in stance and posture of the player due to this height and other personal characteristics. The device does not have to be anchored to the ground and canine readily adjusted to permit of directing balls on sloping surfaces. The device can be constructed at a nominal cost and by means of the particular construction employed, may be built relatively light both as to the track and carriage so as to offer no appreciable resistance to the manipulation of the putter. By means of the improved wheel construction utilized and the form of track employed, minimum friction results and at the same time a minimum amount of noise is produced. Through the construction of the end members, as shown, an open formation is provided through which the ball may readily travel in being propelled toward the cup. By

. means of the construction used for supporting the wheels, the wheels may be adjusted to conform to the gauge of the rails without bending or otherwise distorting the rails or frame.
