Fig. 2 is a-plan of the apparatus. Fig. 3 shows one constructional form of ball carrying and 4spring clutch in part section. This clutch is employed for giving I rotation to the ball about an axis in any direction. Fig. 4 shows another construe# l tional form of clutch in plan. This clutch is forgiving a spin tothe ball about allorizontal axis at right angles to the line .of

flight. Fig. lshowsin elevation and part section a simpler form Aof clutch for delivering the ball spinning about an axiscoincie dent' or approximately so with the direction l .of flight. Fig. 6 is-an end View of same,

and Fig. lis a plan of same. Figs. 8 and 9 are Views of the universal joint employed to carry' the clutches shown in Figs. 3 and 4.

Like letters of reference refer to like parts in all the figures.

Referring to Figs. 1 and `2, A is the base" lor 'support of the apparatus.

' is hinged at G to the base A. This enables the throwing arm D and a portion of the frame to be raised at the front end inorder to alter the trajectory of the ball thrown. The frame is supported when raised uion the cross bars of the hinged rack H.' he height ofthe frame may be adjusted by placing it in another hole of the adjustable or support raclt H.,

' The throwing arm D is pivoted on the in -I inounted on the b'ar F., It is connecte to the front bar J of4 the frame by the sprlngl K. It is also connected to the back bar L of the frame by the cordM. The cord l\lis secured at theother end tio the-buffer' 0 O, are guide bars, one ou each lside of.

the throwing'arm D, to revent any undue lateral movement of the t rowing arm.

`ting the clutch gie with the carrier D1, and at the same time F1 F1, are bars to more firmly secure the end members J, L, of the frame to the' lower bar F. The clutch carrier D1, which may' be a flat or round rodof any suitable matelrial is secured to the top of the throwing arm D, b f means of set screws, and its position A1s a Justable 'lhe clutch P 1s secured to the carrier D1 by means ofthe adjustable' joint D2, which permits of adjusting. or set at a dierent vertical an- .The clutch sired mark, which mark-ma .side that of receivin a ringl ball bearing the -wire 'connection PI. The wirePlfis4 allows-said clutch to be swung laterally.

F ig.. 3.

The string, wire or cord D5 is employed to release the clutch l. as hereafter described. The cord D5 is connected at its lower end to the back frame member F1, it passes behind the eye D3 and thence through the center of the hollow rod Illl to release the clutch. The lcord D'5 becomes taut when the throwing arm D Vis near the end of its stroke, and so exerting a pull on the clutch mechanism releases the ball.

The dotted lines Fig. lA indicate the-other position of the4 throwing arm D. lVhen drawn back to this position extendin the spring K, the catch or hook D4, is p aced behind the pin or eye D3, to hold it in this position. The clutch P is then adjusted to the desired position vfor throwing. The

clutch P which is mounted on ball bearings on-the rod P1 is thenA rotated in whichever direction it may be desired to spin the ball. This is preferablydone by means of'a small pulley fixed to the spindle such as shown P2, Figs. 3, 5, 6 and 7 A piece 'of Stringer the like is wound around the pulley and being pulled in `uuwinding rotates the clutch and ball at a good speed. The catch ,or hook D4 is then released by hand. The spring K pulls the throwing arm D sharply forward, and when near the end of its stroke, the clutch P releases the ball Q, which is thus thrown spinning at the wicket or debe a spot on either side of or in front ot the wicket or the like.

Referring toFig. 3, the ball Q is held by the four levers of which P3, P21 only appear in 4this view. The said four levers are. mountedn fulerum pins .on -the disk or end flange of the sleeve P7, which sleeve is adapted to rotate freely Aon ball bearings fon the solid continuation of the rod or spindle F1.. Each lever is 4provided Iwith a spring as shown on the lever P3, which tends to open outwardly the lever and release the ball, that is to say to place the levers radially to the rod P1. The pulley P2 in this figure serves another and additional .purpose bethe string used for Spinnin the ball. T e pulley P2 is mounted to s ide longitudinally on the'sleeve P. The flange of the ulley'P2 ispressed forward assisted by tlhe action of the sprin P and is so placed that the shorter arms o 'the -levers I, P4, Pi'andP (the latter'not' shown) rest 'upon its edge. The longer-armsof the levers' are thus pressed against' the ball Q to hold it., In order that the, pulley II may lie-slid backwardly soy as to release the levers and ball, and yet be permitted to rotate freely, the' ulley is provided'with 9 having fitted thereto P is shown to a larger scale in passed through a Slet 24diet inde iii the hollow rod l, and the String` or Cord l)i is secured to the wire inside the hollow rod. When the string is pulled, the tour levers are released and tty open ley the action ot their Springs eo releasing the ball.

Referring to Fig. el, the ball Q is held between two shallow cups R R1. These cupe are rigidly fixed to spindles which Carry the pulleys PT l at their other ends. 'l` he said Spindles are mounted on ball bearings fitted within the tubes "l2 R3, te allow of 'free rotation of the cups and ball. rl`lie tubes are carried by brackets as shown fixed to the sliding sleeves lll The Said sliding sleeves llt R aleo carry the pins Rb' RJ respectively, These pass through slots in th inner fixed tubes ,l5 R9 respectively. The length oit the slots Shown dette i, determine the degree ot movement permitted to the sleevesl iipon the said inner til'ied tubes RT llt. Within eaeh of the Said inner tubes RT lli is litted a spring, one end et which ie Secured in the tube end, and the other to the Said pine. Consequently the Said pins, and theret'oi'e the sleeves and (rups Connected thereto the Said ai'e always pulled outwardly by springs. ln order te hold the cups preseed against the hall in opposition to the tension et the said Springs. the doiihle lioolr or deteiit lt provided. The double hook or detent llf is adapted to Slide upon the hollow rod l. llllien the Cups 'll 'lll are pressed together into Contact with the eiip to hold l@ainel the detent Rl" pr ed torwai'd so that the two hools thereon engage and hold the pins RG R7. ie in poeition on the tlii'owiiig` ai'in, he eeen that it the cord lf is pulled, the der tent lt" to which the oord eeeiired in being drawn haelwardlv' the heele; release the pins ll ll".
