MECHANICAL GOLF INSTRUCTOR AND EXERCISER.

Application filed December 29, 1926. Serial No. 157,751.

My invention has reference to a mechanical golf instructor andexerciser, and relates to certain improvements in a'device of that type which is set out in my former application for Letters Patent of the United States tiled Oct. 25, 1926, and numbered 14l3,977. Said former application embodied a track of approximately circular form, serving as a guide for a frictionless traveller to which was attached the end of a golf club or stick used in practice. Associated with the traveller was mechanism for controlling the axial movement of the 'clubin its trip round the track, compelling the same to follow the natural movement of the club in making a stroke. Included therewith was a channel in the face of the track anda roller operat-' ing therein, by which the controlling mechanism was actuated.

In the present invention the channel is replaced by a track onthe face oft-he rail.

forming the main track, upon the'edges of which travels a pair of rollers connected with the control mechanism, and imparting movement thereto. construction and operation of the device is the same as in said former invention, except that the traveller rides on the edges of the track instead of on its faces.

The particular construction, arrangement, and operation of the various parts of the invention will be more thoroughly understood from the following specification, reference being bad to the accompanying drawings, in which;

Fig. 1 shows a fragment of a track upon which the traveller operates, with the traveller in position thereon.

Fig. 2 is a cross-section on the broken line 2-2 of Fig. 1.

The reference number 1 indicates a section of track,.the main part of which is understood to be of a suitable shape and size to enable a player to stand in a central posi tion and describe a stroke with a golf stick, the track serving as a guide therefor. On one of the faces of the track 1 is a track 2, extending from one end to the other thereof. Slidable on the track 1 is a frame 3, by means of rollers 4: at the corners thereof, and grooved to conform to the semi-circular formation of the edges of the track. In the upper part of the frame, which runs on the inner side of the track, is a bearing 5, in

In other respects thewhich is journalled a shaft 6, on the upper end of which is a yoke 7,.connected by a swivel pin 8 with the yoke 9 on the end of a stick 10. This'stick is shown broken away, and would be of suitable length and shape for use as a golf club.

Projected. fromthe bearing 5 is a bracket 1, supporting a bearing 12, in which is journailed the outer end of a shaft 13, the other end of said shaft being supportedin a part of the frame 3. is a .sleeve 14, to which is fixed a bevel-gear wheel 14, in engagement with a bevel-gear wheel 15 on, the lower end of the shaft 6. A gear-wheel 16 is also fixed to the sleeve 1 1, and pivoted on the frame 3 as at a is an arm 17, on one end of which is a segment gear 17, the teeth of which are in mesh with the teeth of the wheel 16. In the other end of'the arm 17 is a pin 19, on which is pivoted a link20 in the opposite ends of which are

rollers

21 and 22, which bear against opposite edges of the track 2. V

During a large part-of its course the track 2 is in parallel relation with the track 1, near one edge or other of said main track, but in another part it crosses from one side to the other, as indicated in Fig. 1. This results in a rocking movement of the arm 1'? and segment gear 18, imparting rotation to the shaft 13, which is communicated through. the

gearing

14 and 15 to the shaft 6 and stick 10 connected therewith. This movement is suflicient to give to the stick a half rotation, and the arrangement of the track 2 is such that the movement begins at the right hand side of the player and ends at the opposite side. In the case of the use of an actual golf club this would have the efi'ect of turning the shaft from a position with the face of the club to the front to a position with the face of the club to the rear, following the natural course thereof. It will be observed that the hands of the player will 23, by the release of which the link and rollers can be removed. This will permit free movement of the stick 10, in case it is desired to use the same without hindrance 'b' the earin and cam track.

suitable track provided with a cam-track on one of its faces, a frame provided with rollers operable on said first-named track, an arm carried by said frame and provided with a follower for said cam-track, a pivotal stick connection in said frame, and means for imparting the movement of said arm to said pivotal connection, to suitably rotate the same.

In a device of the class described, a suitable track provided with a cam-track on one of its faces, a frame provided with rollers operable on the edges of said first named track, and provided with a pivotal connection, an arm rockingly mounted on said frame, gearing connecting said arm with said pivotal connection, a link pivoted to the free end of said arm, and rollers on the ends of said link bearing against opposite sides of said cam-track.

In a device of the class described, a suitable track and canrtrack on one of the faces thereof, a frame movable on said firstnamed track and pivotal connection mounted thereon, an arm rockingly mounted on said frame, means for imparting the rocking movement of said arm to said pivotal connection, to rotate the same, and a follower for said cam-track detachably connected with said arm.

t. In a device of the class described, a suitable track and cam-track thereon, .a frameslidable on said first-named track, a pivot mounted in said frame and stick-coupling connected therewith, an arm rockingly mounted in said frame, gearing connecting said arm with said pivot,a link pivoted to said arm and detachable therefrom, and rollers carried by the ends of said link, engaging the sides of said cam-track.

In a device of-the class described, a suitable track and cam-track on the face thereof, a frame slidable on said track, a pivot supported in said frame and coupling on the inner end thereof, a bevelear wheel on the outer end of said pivot, a bevel gear wheel rotatably mounted and in ineshwith said first-named bevel-gear wheel, a gear pinion rotatable with said second-named bevel-gear wheel, an arm pivoted in said frame, and provided on one of its ends with a segment gear in mesh with said gear pinion, and a follower for said cam-track on the other end of said arm.

In testimony whereof I aflix my signature.
