.6 claims. (c1. 27s-ss) This invention relates to improvements practice putting targets. It is an object of .the invention to provide .a practice putting target so constructed that balls which roll .onto it vare au tomatically returned, .thereby permitting a player to remain at normal putting distance `since each ball is `returned to him.

Another object of the invention is lto provide .a practice putting target including a relatively wide base so constructed 4that balls which .arrive thereon to one side or the other of the center .of the device are guided toa central eiection station, and, when there close a circuit whichV operates a mechanism by which each ball in turn is returned to playing position. Moreover accurately putted balls are immediately returned Whereas balls which go to one side or the other of the center pass down Aa lateral guideway before reaching the ejection station.

Another object of the invention is to provide such a practice putting target including scoring discs suspended over the base, the numbers on which are graduated according to the lateral distance of the discs from the center of lthe base, sc that competing players may score according to their accuracy in reaching the transverse center of the device.

A further .object of the invention is to provide such Va practice putting target wherein the front of the base is upwardly and rearwardly inclined so that a ball must reach the device with sufcient velocity to climb that incline; moreover the, incline is such that a ball which travels up it would otherwise roll about six inches past the target, and have suiiicient momentum to reach and. drop into a cup.

1 Yet another object of the invention is to provide a .practice putting target including a pivoted propelling member so constructed and arranged that it imparts an overspin to the ball, so that even if the device is being utilized on a relatively heavy carpet the balls will travel back to a player located a reasonable putting distance from the device.

Having thus broadly stated some of the objects and advantages of the invention I Will now describe it in detail with the aid of theaccornpanying dra-wing, in which:

Figure l is a front view of the invention, and

Figure 2 is a plan View thereof.

Figure 3 is a section on the line 3--3 of Figur 2 with the propelling member retracted.

l Figure l is a section .on the line 4,-4 of Figure 2, with the propelling member advanced.

Figure 5 is an enlarged partial section on the line 5-5 of Figure 2.

Figure 6 is a detail showing the post `for pivotallly supporting the contact arm, taken on the line @-5 of Figure 5, and a vsection through the arm disassembled from the post.

Figure 7 is a section on the line l--l of Figure 4, and

Figure 8 is a detail showing the central portion or the `rod on which the score :plates are suspended, and some of the latter.

Referring to the drawing, 1 designates a base 'the upper face of which is upwardly and rea-rward-ly inclined from its front margin for a .portion of its length as shown at 2; moreover across the front margin the base is .quite thin so that gohc balls may readily roll thereonto from theV iioor or ground on which the base is resting. Providedacross the back of the base l and .along both lateral edges is va continuous vertical wall 3.

Formed transversely in the base l intermediately of its length and extending from each lateral margin substantially to the cen-ter is Va downwardly and inwardly inclined groove Il of i-ncreasing depth toward the center of the said base. The rearwardly and upwardly inclined portion 2 of the base terminates at the front edges 'of grooves et, and between the rear edges of the said grooves and the back Aof the base l the upper surface of the latter is preferably flat. Formed aiso in the base l centrally of its width and extending forwardly and vupwardly from the back wall 3 is another groove 5, the bottom of which is flush with the bottoms of the grooves 4 at their point of intersection. forwardly of the grooves l before it merges lwith the upwardly .and rearwardly inclined portion` 2 of the said base. It will be noted that the grooves i and 5 are of concave section so that a golf ball will travel freely therealong. Extending transversely over the inclined portion 2 of the base and supported at its extremities by opposite sides of the vertical wall 3 is a rod 6 having a plurality of scoring discs i pivoted thereon and adapted to be swung about the rod by a ball passing beneath them. Also mounted, preferably pivotally, on the rod 8 centrally of its length and over the groove 5, is a central scoring disc la, which is usually so arranged that a ball may pass freely thereunder.

Mounted on the wall 3 centrally of the width of the base l and projecting upwardly therefrom is a bracket 8 having spaced, forwardly extending arms 9 on its upper extremity. 'These arms are parallel and in horizontal alignment with one The groove 5 extends 3 another and support opposite ends of a horizontal pin Ill on which the outer extremities of a U-shaped propelling member I I are pivoted. The two extremities of the member II are retained in sliding engagement with the inner faces of the arms 9 by a spacer bushing I2 annularly grooved centrally of its length and mounted around the pin I between the said arms. Mounted also on the bracket 8, and projecting forwardly therefrom beneath the arms 9, are horizontally opposed guides I3 in contact with each of which the outer face of one side of the U-shaped member II is adapted to slide as the said member is moved pivotally.

Formed substantially longitudinally through opposite sides of the member I I, preferably above the guides I3, are slots I4 to receive opposite extremities of a pin I5 extending through and beyond both sides of a solenoid plunger I6, so that as the latter is moved the propelling member I I is swung about the pin I5. The pin I5 is pressed through openings formed in horizontally opposed lugs of a bracket I1 extending from the front extremity of the solenoid plunger I6. A spacer bushing I8 annularly grooved centrally of its length is mounted on the pin I5 between the lugs of the bracket I1 and is free to revolve around the said pin. In tension contact with the annular groove in the bushing I3 is a hook-shaped extremity of a spring I9. Intermediately of its length this spring is wound around the groove in the spacer bushing I2 and its opposite extremity is secured to the bracket 8. This spring tends t0 retain the solenoid plunger I6 in its rearward position, and the lower, central portion of the U-shaped propelling member II against the back wall 3.

Mounted on the rear face of the wall 3 behind the U-shaped propelling member II is a' housing 26 rearwardly from which, adjacent its lower extremity, a foot 2I extends. Thread-ed through an opening formed in the foot 2I is a vertically adjustable support 22 so that the base may be set horizontal upon the ground. suitably mounted upon the housing 20 is a solenoid 23 in which the plunger I6 is mounted for axial movement. Mounted within the housing 26, and extending rearwardly from the wall 3 in vertical alignment with the U-shaped propelling member i I, is a coil 24 axially through which a core 25 adapted to be magnetized by energization of the said coil extends. The iront extremity of the core 25 -projects through an opening formed through the back wall 3 and slightly in front of the said wall.

Extending forward from the wall 3 above and in vertical alignment with the core 25 is a contact disc 26 rearwardly from which a threaded shank 21 projects through the said wall and has terminal nuts 28 on its rear extremity. Both the disc 26 and the shank 21 are spaced from the wall 3 by a suitable insulating bushing 29. Supported for axial movement through the housing 20 and through the rear wall 3, and in vertical alignment with and above the contact disc 26, is a push rod 30 the front extremity of which is insulated. Mounted around the rod 36, between the rear face of the wall 3 and a collar 3| suitably held on the said rod against rearward movement, is a helical spring 32 which urges the said rod rearwardly. Projecting downwardly from the solenoid plunger I6 adjacent its rear extremity is a trip 33 so arranged that just prior to completion of the forward movement of the said plunger it strikes the push rod 3D and moves the latter forward to break an e1ectrica1 contact in a manner hereinafter described. Means are provided for limiting the movement of the rod 30, and consist, in the present instance, of cotter pins 34 extending through the said rod on both sides of the rear wall of the housing 20.

35 denotes a post the front of which is vertically slotted at 36 centrally of its width, and projecting rearwardly therefrom is a threaded shank 31 which passes through the wall 3 in vertical alignment with the push rod 30. Both the rear face of the post 35 and its shank 31 are spaced from the wall 3 by a suitable insulating bushing 38, and screwed on the rear of the shank 31 are terminal nuts 39. Formed in the base of the slot 36 is a recess to receive one extremity of a helical spring 40. Pivoted in the slot 36 and projecting downwardly therefrom is a contact arm 4I which is supported by a pivot pin 42 extending transversely through both sides of the post 35. The front extremity of the spring 4I) bears against the back of the arm 4I and tends to retain the latterA vertical and at the same time it prevents rebound of the said arm against the disc 26 when the push rod 36 is returned rearwardly thus acting as a snubber. Provided on the lower extremity of theV contact arm 4I and projecting rearwardly therefrom is a contact member 43 which is adapted to make connection with the disc 26, and secured upon the front face of the said arm and projecting beneath the latter is an insulating plate 44 having a magnetic disc 45 secured upon its rear face adapted to make a connection with the core 25.

Adapted to be connected to a source of powernot shown-are two wires 56 and 5I. The wire 5I] is connected to one terminal of the solenoid 23 and to one end of the coil 24. The other wire 5I is connected to the shank 21 between the nuts 28. Connected to the shank'31 and held between the nuts 36 thereon is one extremity of a lead 52 which is connected both to the second terminal of the solenoid and to the other extremity of the coil 24. Consequently when the arm 4I is swung rearwardly so that the contact member 33 engages the disc 26 the circuit is closed. Then the coil 24 is magnetized and retains the disc 45 in close proximity to (but preferably not in physical contact with) the core 25 so that the arm 4I is held stationary, and the electric circuit closed, while the plunger I6 is moved forward by the solenoid 23. However just prior to the time the plunger I6 reaches its forward limit of travel the trip 33 strikes the push rod 30 and moves it forward. This rod then strikes the back of the arm 4I and moves it forward, thereby breaking the contact between the member 43 and the disc 26.

When a ball A rolls onto the base I it either travels directly beneath the numeral I0 and strikes the contact arm 4I, or else it rolls into one of the lateral grooves 4 whence, due to the inclination of the latter and that of the groove 5, it reaches the said arm. In any case the rearward and downward inclination of the groove 5 is such that when a ball A rolls against the contact arm 4I it moves the latter into electrical engagement with the disc 26 and thereby closes the circuit. Then the propelling member I I is swung forward to its position shown in Figure 4, whereupon the trip 33 moves the push rod 36 forward and moves the arm 4I so that the contact between the member 43 and the disc 26 is broken, thereby interrupting the circuit.

It will be noted that the pivot axis of the propelling member II is somewhat in front of the ball A (Figure 3) prior to commencement of the 7,5 forward swing of the said member. This together with the fact that the curved U-shaped central portion of the member II comes in contact with the underside of the ball imparts an overspin to the latter thereby increasing the distance the ball travels. Again due to the support afforded to the member II by the guides I3, and by the bushings I2 and I8 and the spring I9, the member swings through the same path each time the solenoid is energized, and the balls returned by the device always come back to substantially the same spot.

While in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that alterations and modications may be made thereto provided the said alterations and modifications fall ywithin the scope of the appended claims.
