Referring more particularly to the drawings, the reference character 1 indicates a casing which consists of a top 2, sides 3, a front 4, an end 5 and a bottom 6. The top 2 of the casing is provided with slots 'I preferably slightly curved and graduations 8 are placed adjacent each slot. Accuracy indicating pointers hereinafter more fully described extend through the slots 7 and indicate by means of the graduations, the accuracy with which the ball has been hit by a suitable club or, in other words, the accuracy or general direction of the blow or hit by the club. The top 2 is cut-out or slotted as at 2 adjacent the front 4 to accommodate the support for the ball referred to hereinafter.

A relatively long narrow channel member 9 is secured at its open end to the front 4 of the casing by spot welding or in any other suitable manner as at 10. The other end of the channel member 9 is closed as shown at 11. An indicator plate 12 provided with a slot 13 and graduated as at 14 on both sides of the slot is secured over the ,end 11 of the channel member 9 by suitable screws or other fastenings 15. A distance indicator pointer, hereinafter referred to, extends through the slot 13 and indicates by means of the graduations 14 the distance the ball is driven by the force or impact of the club with the ball.

A relatively long tubular hollow guideway 16 is adapted to be received in the channel member 9 es most clearly seen in Figures 1, 2 and 4. This guideway is provided with a horizontally extending slot 17 in its upper periphery which extends throughout its length except -for the portion 18 at one end thereof. A pneumatic pressure cylinder 19 is slipped over the end 20 of the guideway 16 as at 21 and secured. thereto in any suitable manner and is also received in the channel member 9, as shown in Figures 1 and 2. The other end 22 of the guideway pro`- pivot with an angular vthe same.

jects beyond the end of the channel member 9 into the casing 1 beneath the slot or cut-out portion 2' in the top thereof, most clearly shown in Figures 1 and 3 and is loosely positioned therein to allow of limited movement.

A support 26 consisting of a cup portion 24 in which is held a golf ball 25, a slide or plunger portion 23 connected by a flattened portion 26hsupported above the top 2 of the casing so that it is unobstructed and may be readily hit with a golf or other club.

vAttached to the bottom 6 within the casing 1 are a. plurality of indicating levers or arms. The levers or arms are arranged in an upper pair and a lower pair. 'Ihe upper pair of levers or

arms

26 and 27 are pivotally mounted on

upstanding pins

28 and 29 respectively, which extend from and are secured to the bottom 6. The free ends of the levers 26'L and 27 project through the slots 7 in the front 2 of the casing and are formed with pointers 26' and 27 respectively. The lower pair of

levers

30 and 31 are pivotally mounted adjacent their ends on upstanding pins 32 and 33 respectively, which also extend from and are secured to the bottom 6 of the casing. The free ends of the levers or indicating

arms

30 and 31 project through the slots 7 in the top-2 of the casing and are formed with

pointers

30 and 31. The opposed edges of the

levers

26 and 27 are spaced apart adjacent their respective pivot points and are parallel as at 34. Lever 30 is provided adjacent its portion 35, the inner edge of which as at 36,A is substantially at a right angle to the lever. Lever 31 is provided adjacent its pivot with an extended portion 37 having an edge thereof parallel with and spaced from the right angle edge 36 of the lever 30.

An operator 38 for the indicator levers is mounted for universal movement in a stationary bracket 38 which is secured to the underside of the top 2 of the casing 1 in any suitable manner. The operator 38 is forked as at 39 at one end and a ball 40 is provided at the other end of A pin 41 is secured to the operator as at 42 and depends from the underside thereof. The ball 40 of the operator is received in a ball socket 43 formed in the stationary bracket 38. The forked ends 39 of the operator are provided with openings, and the end 22 of the hollow guideway 16 is also formed with openings. The forked end 39 of the operator straddles the end 22 of the guideway and the openings in these respective parts register, 'to enable a suitable pin 44 to be passed into these openings and through the hollow guideway to connect the end 22 of the guideway with the indicator operator, thereby allowing of a universal movement of the indicator operator.

The end 22 of the guideway 16 is. held in spaced relation to the bottom 6 of the casing 1 and the bottom of the channel member 9 by means of the operator 38. The other end 20 of the guideway which has attached to it the air cylinder 19 is' also held in spaced relation to the bottom of the channel member 9 by means of a projection 9' upon which it rests, thereby form- A channel member in the lower portion of the substantially throughout its length. The extreme outer end of the air cylinder 19 abuts the distance indicator plate l2 as at 19 and longitudinal movement of the guideway is thereby prevented. The projection 9 is spaced from the closed end of the channel member 9 as is also the extreme end of the air cylinder 19 thereby forming a second chamber 11a in the channel member 9.

A substantially T-shaped distance indicator 45 having a pointer 46 formed above the head 47 and providing grooves 48 at either side thereing a chamber 9n A of is adapted to slide freely in the slot 13 of the indicator plate 12. The depending portion 45 and the head 47 slide within the chamber 1l^ and of course the pointer 46 is exterior of the chamber 11.

'I'he pneumatic pressure cylinder 19 has therein a floating abutment 49. This abutment consists of two cup washers 50 which are spaced apart by a sleeve 51 and connected together by means of a threaded bolt 52 and a nut 53 forming a single unit. The unconnected end of the cylinder 19 is closed by a screw disk 54 which has attached thereto a sealing washer 55. The disk and washer are provided with a central aperture 56 through whichextends thev outer end of a piston rod 57. This rod has attached thereto interiorly ofthe cylinder 19, a. piston 58. This piston consists of oppositely disposed cup washers 59, a spacer 60 which are all held together by nuts 61 engaging screw threads on the rod 57 on opposite sides of the cup washers 59.

An upper friction bar 62 consisting of a narrow iiat strip of metal having openings 63 and a lower friction bar 64 with openings 65 and similar in shape to the upper bar 62 are positioned on upstanding pins 66. These pins ex' gagement with the upper sides of the indicating levers or

arms

30 and 31, as will be clearly seen by referring to Figure 7. A re-setting bar 67 is pivotally mountedintermediate its ends on an up-standing pin 68 which is secured to the bottom 6. This re-setting bar is provided' adjacent each end with downwardly extending pins 63 and intermediate of the pins 69 and the pivotal point of the bar 67 there are additional downwardly extending pins 70. One end 71 of there-setting bar has an aperture therein and one end of a coil-spring 72 is connected through the aperture in the bar and the other end of the coil spring is secured to any up-standing projection 73 which is secured to the bottom 6- of the casing. The other end 74 of the re-settingbar is provided with an aperture and has secured or held therein a flexible wire cable 75.. This wire cable extends from the point of connection to the re-setting bar 67 below the guideway 16 in the chamber 9Il formed in the' channel member 9 and extends through an opening 76 in the projection 9' and through an opening in. the depending portion 45' of the distance indicator 45. The free end of the flexible cable 75 is enlarged as at 77. The arrangement of this cable wherein the distance indicator 45l slides will be clearly seen by referring to Figure 2. A` pedal 78 is pivotally mounted on a pin 79 which extends through the lower portion o f thepedal and 'in the chamber 9*il and in the chamber 118L A wire or cable extends and the free end of the wire or cable 81 is connected to the re-setting bar 67 adjacent its pivotal connection 68, as shown at 85.

'Ihe parts of thedevice in their original positions are shown in-Figure 1 and in the other figures of the drawings. It is to be understood that the device as a whole is supported on the floor or on any other suitable support. The support 23 for the ball 25 normally rests in the slot or cut-out portion 2- in the top 2 of the casing 1 and the slide portion 23 of the ball support 26 is mounted in the guideway 16 which extends below the slot 2' in the top of the casing. The end 22 of the guideway 16 has pivotally connected thereto by means of the pin 44 theoperator 38 for the indicator levers. This operator 38 is mounted for universal movement in the stationary bracket 38' and the pin 41 depends from the operator 38 and extends into an opening formed by the particular arrangement and formation of the indicator levers 26a, 27, 30 and 31 adjacent their pivotal points. The pin 41 of the operator is in very close proximity to the respective edges of all of the aforementioned indicator levers. In this manner and the particular arrangement of the operator with regard to the indicator levers, when the ball is hit with a suitable club and when and if the ball is hit accurately, the slide or plunger portion 23 of the support 26 for the ball will be driven forwardly in the guideway 16 and the end of the plunger or slide 23 will forcefully engage the head of the bolt 52 of the floating abutment 49 and air will be compressed within the cylinder 19 which is closed and the rod 57 connected to the piston 58 will be projected outwardly of the cylinder and contact with the distance indicator 45 and move the same in the slot in the indicator plate 12 to indicate the distance of the hit and Vsimultaneously with such engagement of the slide or plunger 23 with the oating abutment 49, the said abutment will rebound after compressing air in the cylinder 19 against the piston 58 and strike the plunger or slide 23 and cause the same to move to its original position in the guideway beneath the slot 2' of the top 2 of the casing. However, if the ball 25 is not hit accurately with the club, that is, if the ball is topped, lofted or hit on either side of the radial center of the ball, immediately upon such an inaccurate hit of the ball, the operator 38 and consequently its depending pin 41 will either be moved upwardly or downwardly or to one side or the other, and the fact that the pin is in engagement with all of the indicating

levers

26, 27, and 31, depending upon the movement of the pin 41 caused by the inaccurately hit ball, the said pin will engage one of these levers and indicate by means of its respective pointer and the graduations 8 on the top 2 of the casing the inaccuracy of the hit. Immediately upon hitting the ball, the slide or plunger 23 of the support 26 for the ball will go forwardly in the guideway 16, engage the floating abutment 49, and the rod '57 of the piston 58 will be forced outwardly and the probable distance of the drive or hit will be indicated by the pointer 46 and the graduations 14 on the plate 12, and the support will be returned to its initial position, as

herein before described. In other words, if the ball is hit accurately there will be no indication caused by the operator 38 and itslassociaticn with the indicating

levers

26a, 27, 30 and 3l and only the distance of the hit will be indicated by the pointer 46 on the indicator plate 12, but

when the ball is inaccurately hit, that is, topped,

lofted, hooked or sliced, such a hit will be indicated byeither of the

pointers

26', 27', 30 and 31 and, of course, the probable distance of such a hit will also be indicated by the pointer 46 on lthe indicator plate 12.

Istood that the device might well be used as a game. The device will accurately indicate whether or not the ball has been hit correctly by the club and if so, only the distance of the drive will be indicated, but when the ball is inaccurately hit, such a hit will be indicated as well as the distance of the hit or drive. In any event, and no matter how the ball is hit, the floating abutment 49 will automatically return the support 26 for the ball 25 to its original position so that the same is ready to be struck another blow with a suitable club.

This device will indicate precisely whether or not the ball is hit correctly and accurately and also the probable distance of the drive or hit of the ball and by using the same, one may perfect his golf game and be assured that if the accurate hitting of the ball has been mastered by practicing on this device, his game on the golf links will be greatly improved. The device is so constructed that it will not readily get out of order and may be used byl children or grownups as a golf practice device or as a game or in any suitable manner such as desired by the user.
