T ORNEY CL mu Patented (let. 4, 1932 warren STATES ANGELO N. ALBERA, OF CONCORD, CALIFORNIA BASEBALL GAME Application filed December 5, 1930. Serial No. 500,214.
This invention is for a base ball game, and has special reference to a game in which a mechanically driven ball is driven at a speed approximating the normal speed of a pitched .55 ball, and in a proper position to be intercepted by a bat wielded by a person in normal batting position.
The main object of the invention is to provide a base ball with mechanical means for driving or pitching the ball, at a speed substantially equal to the normal speed of a hand pitched ball, and in a plane adjacent the batter Which is considered a fair ball in the regular game of base ball.
Another object of the invention is to provide a game as outlined which may be played indoors or outdoors and which will test the skill of the batter and develop accuracy in batting.
A further objectof the invention is to provide a device as outlined with registering and indicating means, for the purpose of indicating the force of impact with the bat and whether a fair or foul ball was struck,
whether the ball is driven straight, for a fly,
grounder, or punt, the exact conditions being registered at the time of impact.
Other objects and advantages of the invention will become apparent as the descrip tion is read 011 the drawings forming a part of this specification.
The invention consists primarily of a track or guide, a carriage freely mounted in the T guide and having a forwardly extending arm on the end of which is secured a base ball,
the arm being adapted to swing in all directions except forward relative to the carriage and having a plurality of pivoted joints in ngular relation to each other, and resiliently retained in normal positions, indicating or registerin means operable by means of joint movement, and a catapult for projecting the carriage along the track or guide to the op 41 'posite end, where the energy of the moving carriage is dissipated in a resiliently restrained arm which immediately transmits the energy to the carriagefor returning it to the starting point, and means for resetting and releasing the catapult.

The invention consists of a track or guide indicated as a pair of opposed channel members 16 preferably of a length approximat ing the distance between the pitchers and catchers boxes of a base ball diamond, so as to provide similarity of conditions relative to a hand pitched ball. Suitable supports 17 rigidly secure the track members in proper alignment. A guard rail 18 is preferably spaced parallel to the track to prevent'injury to bystanders by getting in 'thepath of the ball and arm when catapulted.
The catapult is located at one end of the track and consists of a pivoted arm 19 fixedly mounted on a shaft 20 on the opposite end of which is fixedly secured a gear 21, the shaft 20 being rotatably mounted in a bearing 22; Arm 19 has rotatably mounted at the outer end, a roller 23 pivoted on a stud 24 and adapted to engage the rear end 25 of the carriage. A projection 26 integral with arm 19 cooperates with a latch for retaining the arm in retracted position.
The power for catapulting is derived from a spring 27, seated against a head 28 of a frame or cylinder 29 which is secured to the frame work or supports by a bracket 30. A red 31 is slidable in the head 28 and has rack teeth 32 formed at the upper end which mesh with the gear 21 which is keyed to shaft 20 as indicated at 33. Rod 31 extends through spring 27 and has a thrust washer 34; and nut 35 cooperating with the opposite end of spring 27 It will be noted that with arm 19 in retracted position, rod 31 is drawn upward by gear 21 and spring 27 is thereby compressed.
The resetting mechanism consists of a cylinder 36 having a piston 37 to which is secured a piston rod 38 which is slidable through cylinder head 39, and has rack teeth formed at the upper end as indicated at 40, which mesh with a clutch gear 411 rotatably mounted on shaft 20. Gear 41 has engaging means consisting of a pawl 42, pivoted in gear 41 and 43 and urged forward by a spring 41 1, into a notch 15 formed in gear 21, a recess being provided in gear 11, as mdicated at 46, into which the pawl. 12 may be retracted by cooperation with the normal side surface of gear 21. An encompassing bracket 47 is integral with bearing 22 and provides sliding bearings 18 for the racks 32 and 10, and an end bearing 19 for shaft 20. Cylinder 36 is suitably mounted on a bracket which is fixed to a support 17. he cylinder has pipes 50 and 51 communicatmg with the opposite ends and controlled by a four way valve 52 which communicates with an exhaust 53 and a fluid supply 5 1. A lever 55 actuates the valve by cooperation of a spring 56. A rod 57 fixed on piston rod 38 cooperates directly with the end of lever 55 and a rod 58 fixed on spring rod 31 cooperates with one end of a centrally pivoted lever 59, the opposite end of lever 59 cooperating with the under surface of lever 55 to provide a reverse action of valve 52.
The latch mechanism consists of a bolt 60 slidably mounted in a bearing 61 and pivoted at 62 to an L shaped lever 63 which is pivoted to a support 17 at 64:, bolt 60 and projection 26 having cooperating bevels formed at the ends.
The opposite end of the track. is equipped similarly except the cylinder 36 and all cooperating parts, as also the latch mechanism 63 is omitted, and consists of the arm 19, roll.- or 23, shaft 20, gear 21, bearing 22, rack and rod 31, spring 27, housing 29 and cooperating parts, and is only adapted as a shock absorber and rebound device, consequently is adjusted to stop in an angular position as shown at 65.
The carriageconsists of a base 67 mounted between the channels 16 and guided thereby through vertical rollers 68 and horizontal rollers 69 which are pivotally mounted on the carriage base 67 and preferably on roller or ball bearings 70, recesses 71 permit gi pg close coupling of the rollers in the base Integral ears 72 project forwardly from the carriage base 67 and pivotally receive link member 73 of the ball carrying arm, which is fixed to pivot pin 74:. A spiral spring 75 is fixed to the one end of pin 74, as shown at 76, and has the opposite end fixed to one of the cars 72 as at 77 which is located to provide just sufficient tension to overcome the weight of the ball arm and ball. being thus neutralized and normally maintaining the ball arm in a horizontal position,
The other end of pin 74has fixedly secured thereon a collar 78 having an upwardly proecting pin 79 fixed therein. A dial 80 is provided withindex marks of a suitable nature readable from zero in both directions. and is fixed to the one of the ears 72 as indi cated at 81, and has an integral collar 82 formed to provide a non-rotating bearing for the hands 83 and 84 which are frictionally retained in relative position. The hands 83 and 84 are formed alike but reversed as to mounting and consist of the pointer 85, hub 86, and offset arm 87, the'inner edge of which is onset from the center of the pointer a distance equal to the radius of pin 79 so the pointers will be in registry when the arms 87 are in contact with pin 79. A collar 88 retains the hands on the collar 82. Arm 73 is provided with a yoke end consisting of a pair of ears 89 disposed transversely to the ears 72 and has pivotally mounted therein, the ball carrying arm 90, which is fixed to the pivot 91, the construction and arrangement of parts being identical to that described for the other joint, except only one hand 99 is employed, as the swing of the arm is only in one direction, a stop pin 92 fixed in a projection 93 integral with arm preventing back swing of the arm, and a single reading dial 9-1 is used.
T e arm 90 has a right angle joint and indicating means at 103 which is a duplicate of the first joint indicated at 104:. A base ball is secured to the cupped end 105 of the forwardly extending portion 106 of arm 90 by any suitable means, such as cementing.
The operation of the device is as follows: A fluid supply is delivered to cylinder 38 through pipe 54:. At this time, the arm 19 5 ply through pipe 50 to the upper end of the cylinder, which acts to force the piston 37 down, drawing down on rod 38 and turning gear 41 counter-clockwise. Pawl 42' is engaged in notch 45 and drives gear 21 in the jsame direction, which meshes with the rack 32 on rod 31, drawing rod 31 upwardly and compressing spring 27, and coincidently swinging arm 19 to the position shown at 97 in Fig. 1, and as shown in Fig. 6. As the .arm is swung back, the carriage follows, due
to a slight down grade of the track, as indicated in Fig. 13, the carriage coming to rest against the roller 23, the arm 19 being drawn back sufficiently to cooperate with the latch dsbolt 60 which is caused to engage by the weight of lever 63. As the piston nears the bottom of its stroke plunger 57 fixed on rod 38 cooperates with lever 55 until center is passed, when spring 56 throws lever 55 the ebalance of the way, reversing the valve, di-
recting the fluid supply through pipe 51 to the lower end of the cylinder 36 and opens the upper end of the cylinder to the exhaust 53. The piston is forced upwardly, rotating 011 8211 41 in a clockwise direction, pawl 42 acks out of notch 45 and over the side surface of gear 21. The pressure is maintained in the cylinder, thereby offering no hindrance to the free operation of arm 19 and spring 27.
35 This places all parts in readiness, and a batter takes his position, as shown in Fig. 1. Lever 63 is raised, retracting bolt 60 and releasing arm 19. Spring 27 draws rod 31 down, rack 32 cooperating with gear 21,
which, being keyed to shaft 20 swings arm 19 to the position shown at 96 in Fig. 1, roller 23 cooperating with the rear end 25 of carriage 67, drives the carriage at high speed along the track 16. As the carriage approaches the position shown in Fig. 1, the
batter strikes at the ball with a regulation bat 98. Should he fail to hit the ball 95, none of the hands, 83, 84 and 99 would be moved and all would register zero. In case the bat would contact, as shown at 100 in Fig. 6, glancing the lower surface of ball 95, hand 99 would be swung about, indicating on the dial the horizontal component of the force, the hand remaining in its indicating position until manually returned to cooperation of the arm 87 with pin 79. Coincidently hand 83 would be moved counterclockwise on dial 80 indicating the vertical component of the force, and the combination 'of the vertical and horizontal components would provide the necessary data for calculating the tangent and obtaining the theoretical angle of flight of the ball. A tipped ball would show no horizontal component and would indicate a foul ball.
Should theball is struck late, hand 83 would be moved to the left and indicate travel of the ball in right field. It will be seen that the exact conditions ofcontact of the bat and ball may be ascertained by the indicators, which indicate the force componentsin all directions, and the exact direction of flight may be calculated.
The carriage continues until the front end 107 contacts with roller 23 in the position shown at 65, the ener y of the carriage being spent in forcing lever 19. back and compress ing spring 27 at the catchers end. As soon as the carriage comes to rest, the energy stored in spring 27 is transmitted to arm 19 which returns to the position shown at 65, driving the carriage back to the pitchers end at a substantiallylow speedand which is stopped by contact with roller 23.
At the time arm 19 is released by lever 63 and swings to the position shown at 96, Fig. 1, by the force exerted by spring 27 through rod 31 which returns thereby to the lowered position, a finger 58 fixed to rod 31 cooperates with lever 59, which cooperates with the undersurface of lever 55, reversing the fluid supply and causing piston 37 to be forced downwardly, drawing down on rod 38, rotating gear 4-1 which clutches with gear 21, drawing up on rod 31 and compressing spring 27, coincidently returning arm 19 to the position shown in Fig. 6.
It will be noted that the device is automatic in operation, requiring only the. release of latch 60 by means of lever 63, and resetting of the hands of the indicators. Charts may be prepared from which the travel and direction of flight of the ball may be read directly from the values obtained from the respective indicators.
It will further be noted that a scientific game is thereby provided which is instructive and physically beneficial and a source of pleasant recreation, and it will be understood that variations in construction and arrangement of parts which are consistent with the appended claims may be resorted to without detracting from the spirit or scope of the invention or sacrificing any of the advantages thereof.
