To all whom it may concern.'

Be it known that l, ROBERT B. PETER, a citizen of the United States, residui@ at Rockville, inl the county of Montgomery and State of' Maryland, li ve invented certain new and useful improvements in Captive Golf Apparatus; and l do hereby declare the followingi to be a lull, clear, and

`consists in the construction and combinations of parts ashereinalter described and claimed.

ln the accompanying drawingswFigure l is a perspective view of my apparatus, the direction pins not being shown. Fig. '2V-is a plan viewF of the complete apparatus.

Fig. 3 is a cross section on the line 3 3 of 2. Fig. 4 is a section through a part of thge apparatus showing the guide. Fig. 5 isa perspective view of a inodilied 'form ol apparatus 1n which the weighted box is replaced by a spring scale. Fig. 6 is a top plan view oi the saine. Fig. 7 1s a perspecvis a tive view of the sliding pointer, and Fig. 8

perspective view of a modified i'orni thereof. f a, represents a tablatvhich may be niade of any suitable material', but if inade of inetal should be made of soine inetal that will not rust readily linda' the influence of the Weather. This t ble is lprovided with four Shar ened lees b `referabl .made of iron i l i i j represents a golf ball which is perforated and through vfliich'passes o heavy string lc which also passes through toe guide a'nd is attached to the box g, which slides loosely on the top of the table a.' The string lc is usually about the size of 'an ordinary chalk line, and acts to gradually overcome the movement e2 the golf bal alter ifhas been struck, so that il, for example, the'oall .is struck witii a 'orcegreat enough to ordi narily send? it one hundred and 'fifty yards, the weight of the string will gradually overw corne the niovenient of nail; which at the end will give a slr jerk to the box g, and the extent olf movement oi this box as inH dicated on the scale a ill denote the force with which the ball is strucln, from which the distance tnat the ball would usually have. traveled can be readily calculated. I should be noted that in use tile string l: is

laid on the ground in a nn'nliero loose coils so that when the ball is struck, it will not ily back, and this isan important ieature oi niy invention.

For the purpose oi indicating the direction in which the golf ball is driven, l provide a series of Wlialebone pins W lli are stuck in the ground on lines radiating frein the guide f, and at equal distances therefrom, these pins being lettered mr, n, o on the draw ing. The position which" the ,string 7c assurnes when it drops on the ground, with relation to said pins, will enable the operator to determine Whether 'he pnas driven the ball in exactly the desired direction.

lt is well 1irnown tlistdiierent kinds of golf clubs are selected with reference te the length of the stroke. l therefore provide a series of different .sized Weights, so tliat one size could -loe put in the box when a driver is being'used and another size when a mid-iron is used, etc. y

The operation of the niodiication shown in Figs. l-l is as icolloaf'szw'llie apparatus is set in the position shown :in the drawing, care being taken that the table is set level. The heavn :rinl is -draii'n that it is practically straight between the box and the guide, and the reinaindr of the sv so arranged in a loose coil as shown on the drawing, the ball being placed upon an irrdin'ary tee. lhe user tlien strikes the ll exactly if he were playing the regni golf.. The ball its flight, of course. straiglitens out gradually lessens the i'oi'z-e with which the fics . 1 ball .is traveling, until finally the string behomes straight, 'when it exerts a sharp pull `upon the box g, moving the same over the scale, the divisionsf of the scale and the rg/weights in the box being so proportioned that the user can calculate just how far the ball would go if struck in the usual manner. Furthermore, the relation of the string c to vvthe Whalebone pins enables the player to see if l he has driven the ball in the desired direction. Y Referring to the modiiication shown vin Figs. 5 to 8, in these, figures the sliding Weighted boxis yreplaced by a sprin scale having a ratchet or other .means t ereon which revents the return of the ointer at the end) of the4 *stroke until it is reileased b the golfer. p ,represents a spring scale muc 1 like the ordinary ',h; scale now on the market, provided witha central aperture q and an eye r, mounted so as to rotate in one end thereof. A in'fs'is` adapted to passthrough this eye an be `driven into the ground, as shown in Fig. 5.' "The part p 'is rovided with the ordinary scale marks an with a f1.2 t ratchet it 'u represents the pointer, which is providedl with grooves 'u in its sides. `This pointer is adapted to slide in the open space of the'frame, and is g'uided by the sides t ereof.. To the pointer is, attached a rod w,

Se having an eye a: at the end thereof, and this rod inside of the frame is surrounded by a coiled spring. Pivotally mounted on the pointer'u is a ratchet 1, supported ona pin 2 in bearings on the pointer, and having its rear'e'nd normally4 pressed downward by the spring 3, the rear end of the pawl being adapted to` engage the teeth of the ratchet t. ln Fig. 8 a modified form of the pawl is shown, which is provided with an enlarged 40 end 4 which is adapted to frictionally contact with the top or one of the sides ofthe frame of the scale and is pressed down by a spring 5 into contact with said side, so that the poing ter'maybe readily moved forward, but the rearward movementl thereof will be stopped by the awl 4 unless the spring 5 is compressed. y the user. Direction ins such as 1n, rn., and o are also provided wit 1 this modiiication of the apparatus, but they are not shown on thedrawin The advantage of this form 'of the apparatus is that it is small and light and can be carried in the pocket and set dbwn anywhere, simply by driving the pin s through the eye r into the ground, said e *e being loosely engaged with saidpin so that the scale may be moved freely therearound. A heavy string 6 is attached at one end of the eye :t and at the other end to a golf ball 7. The operation of the form of the device shown in Figs. 5 to 8 is as follows :-The parts being in the position shown in Fig. 5, the ball is struck by the golfer and the heavy string slowly overcomes the momentumoffthef'ball. When the string is straightened out, it exerts a pull on the rod w, compressing the spring y and moving the pointer u a distance over the scale proportional to the'force of the blow. The ratchet locks the pointer at the extreme position of its forward movement and the golfer can then calculate the distance the golf ball would have moved il free. When it is desired to use thea paratus again, the awl is released from t e ratchet teeth or rom the side of the frame and the parts returned to their original position.
