This invention relates to apparatus for throwing targets, such as clay, composition, or ,wooden targets of any size. The specific object of the invention is to provide an apparatus which will hold a large number of stacks of targets and which will bring the stacks into successive register with the target-striking or throwing element, means being provided for securing adjustment in the elements controlling angles, height and lateral spread of the target flights. The apparatus is particularly adapted for heavy duty use, i. e., for operation continuously over long periods of time and with relatively large or heavy targets, so that the apparatus is adapted for military training of marksmen.
The invention will be described with reference to the accompanying drawings, in which:
Figure 1 is a view in elevation, partly broken away, illustrating an embodiment of the invention.
Figure 2 is a plan view of said embodiment.
Figure 3 is a partial vertical section, taken on the line 3-3, Figure 1.

Figure 9a is a fragmentary elevation, partly broken away, showing a target on the throwing arm, the parts being in position for throwing action.
Figure 10a is a plan View, partly broken away, of the elements illustrated in the preceding figure. Figure 101) is a transverse section through the throwing arm, showing its cushion contact face for the targets, a target being shown ready for the throwing action.
Figure 10 is a horizontal view, partly broken away, on the line iii-l0, Figure 9, the target throwing arm being at the end of a throwing stroke and at the instant that the target leaves the arm, the target still being engaged by the positioning button therefor.
Figure 11 is a horizontal section on the line ll-l I, Figure 1. In this view the primary elements for oscillating the apparatus on its sup-.
porting frame are shown at the left, it being understood that the lever arm II] is swung about a fixed fulcrum carried by said supporting frame.
Figure 12 is a view in elevation showing the supporting frame and the manner in which the apparatus is mounted for oscillation thereon.
Referring to Figures 1 and 12, it will be seen that the apparatus is carried by a frame generally indicated at F, the frame having a bearing boss i which receives the reduced upper end of a post or vertical shaft 2 carried by the supporting frame 3 upon which the apparatus oscillates,
Referring to Figure 12, it will be seen that supporting frame 3 carries an arcuate table 4, a plan View thereof being shown in Figure 11. Frame F is provided with rollers 5 supported by and movable upon table 4.
Frame 3 is supported upon legs such as a plurality of legs of the type indicated at 6, Figure 12, and an opposite adjustable leg construction which may comprise an internally threaded tubular member 1 dependingfrom supporting frame 3 and into which is threaded a leg 8 which may carry an annular handle 9 by means of which the height of the leg as a whole may be adjusted. This adjustment will determine the angle of operation of the apparatus and hence the angle at which the targets are thrown.
In the operation of the apparatus frame F and hence all of the operating parts will be oscillated. To such end the upper extension of post 2, shown at 2x, Figures 6 and 12, pivotally supports the arms In of a link comprising said arms and the tubular connecting end members Iflw, the outermost of said members relatively to post extension 21: being formed with an elongated raceway shown in Figure 8 at Iilxx. In this raceway is projected a stud Ha: carried by and eccentrically of a gear wheel H which rotates on a shaft [2, the latter being journalled in a bearing boss [3 carried by a member of frame F (Figure 6).
Frame F carries a motor I4 having a drive gear I-5 (Figure 11) which drives a gear IS on a shaft I] carried by frame .F (Figure 11), the hub of gear l6 carrying a pinion l8. Pinion l8 drives a large gear IS on a shaft 20 (Figure 1) and gear I9 is in mesh with said gear ll.
As gear wheel ll rotates stud Ha: will operate to pull the target throwing apparatus to the left and to the right in an oscillatory movement, the apparatus thus having a pivotal movement on post 2 of the supporting frame 3 whilst rollers of frame F move back and forth in the raceway 4 of said supporting frame 3.
With reference to the motor l4, it will be understood that this term may include a motor per se and a reduction gear assembly from which drive gear I5 is immediately driven, and that this is the preferred arrangement.
As the target throwing apparatus is oscillated to the left and right bythe means above described, the target stack carrier will be given intermittent movement to bring the stacks in succession into register with the target throwing or striking element. For the said purpose the target stack carrier comprises a Vertical hub 2| which rotates in tWo interlocking bushing members 22, 2222, Figures 3 and 5, which are carried in an upper horizontal member of frame F. At an intermediate portion bushing 22x is shouldered to abut the said horizontal frame section and also is provided with a set screw at 23 by means of which it is secured to hub 2! so as to rotate therewith. The hub itself is shouldered immediately above bushing 22 so as to engage the flanged upper periphery of the latter. Swaged upon bushing 22 is an annular ratchet 24, Figure 4 the ratchet being engaged by the spring-pressed pawl 25 of a pawl lever 26 having a slotted outer end which receives a pin 21 carried by reciprocatory pawl drive arm 28 which is mounted in the apertures of straps 29 carried by said horizontal frame section of frame F.
As illustrated in Figures 9 and 10, the pawl actuating rod 28 is provided at one end with a forked extension 28x in which is mounted a roller 39 on a stud shaft 3| (Figure 9). Roller periodically is met by the actuating area of a cam 32, on shaft 23, which shaft also carries gear wheel l3. In each rotation of shaft an actuating movement is imparted to rod 28, and the stack carrier thereby is given a movement to carry one stack away from the target striking arm, later to be described, and move a fresh stack into register therewith. After each active movement of rod 28 the latter is returned to initial position by a spiral spring 33 at one end abutting actuating member 28110 and at its opposite end abutting one of the two members 29.
The hub 2| is formed at its top with an annular flange 2|:v having a plurality of threaded apertures to receive screws 34 connecting the hub with the disk-like center 3502 of the primary rotatable target carrying member. In the present embodiment this member is formed with spokes 35 extending radially from member 351:, and between each spoke and its adjacent spoke is held an upwardly projected target stack holder having opposed curvilinear target engaging faces 36:0. The assembly of spacer members provides a plurality of target holding cups which do not completely encircle the targets, each cup exposing the edges of its stack of targets for engagement therewith by latch pawls. Each target holding cup is associated with a latch-pawl holding rod 31 carrying two superposedlatchpawls 38 normally impelled by springs 39 into engagement with two lowermost targets 4! As shown in Figure 2, each latch-pawl 38 is formed with an angular operating finger 382: for a purpose'to be hereinafter explained.
The target throwing arm is' best shown in Figures 9, 9a and 10 at 4|. It comprises a plate having a depending hub 4k: adapted to oscillate on the frame F, a vertical shaft 42 entering the hub and being fixed thereto. As shown by Figure 9a, the shaft has fixed thereto a lever arm 43 connected to a spiral spring 44, one end of the spring being secured to a pull rod 45 pivotally connected at 46 to gear wheel l9.
In each rotation of the gear wheel spiral spring 44 i put into tension. Prior to such tensioning of spring 44, however, pull rod 45 will have been moved to the right of its position in Figure .9a, releasing the tension of spring 44 and a relatively light spiral spring, shown at 41, Figure 1, one end of said spring 41 engaging shaft 42 and. the other end a stop 48 on frame F will rotate shaft 42 in a clockwise direction so that target throwing arm 4| is brought to the position of Figure 1 and also Figure 9a, and to target receiving position. At this point a latch arm 49 pivoted at 50 on frame F will be released by its actuating pin 5| (which pin is carried by a disk 52 on shaft 23) and the latch arm will have gravitational movement to the position of Figure 1 and Figure 9a the latch arm engaging a finger Marx on the target throwing arm 4| to hold the arm in target receiving position.
The stack carrier rotates immediately above a table-like disk 53 formed with an aperture at 531:, Figure 9a, for the targets from each stack. Secured to table 53 by screws 54a: is a pawl-releasing cam 54 for the target latching-pawls, having a low area and a higher area at 541:. Thus when a stack of targets is brought over target passageway 531: in table 53 the lowermost pawl 38 will have its actuating finger 38x so engaged by the low area of cam 54 as to release the lowermost target which will drop down onto the target throwing arm 4| to the position of Figure 9a and against the side of a positioning disk 55 on said target throwing arm. The target immediately above the lowermost target of the stack will still be engaged by the upper of the two latch-pawls 3B which, in turn, will be released to drop the stack of targets when the stack is moved away from the target passageway in the said table and the finger of the said upper latch pawl meets the higher area 54st of cam 54.
A target now being in throwing position on target throwing arm 4 I, the continued rotation of shaft 20 and its disk 52 will carry pin 5| to the position of Figure 9 thereby imparting a releasing movement to latch arm 49 and the target throwing arm will be impelled by spring/i4 with a sharp throwing movement and the target will be thrown into the air at the angle for which the apparatus has been adjusted.
The targets are, in many cases, very frail and to avoid any striking or fracturing thereof by the target throwing arm, we provide the vertically extending target engaging ledge 4| a with a cushioning strip Mb of rubber or the like, for direct engagement with the target to avoid fracturing the same in the throwing movement.
In the present embodiment the rotary stack holder is provided with ten stacking holding units each adapted to hold ten targets, more or less, and thus the device illustrated has been designed for throwing targets without re-loadin'g. Shaft 20 will be given a rotation for each target thrown. In such rotation the stack carrier will be advanced one step, the target throwing spring 44 will be placed under full tension, the latch 1ever 43 will be movedto release the target throwing arm so that the tension of said spring will imof rotation at which thespring is under substan v part operative movement to the arm, and thereupon the spring pull rod 45 will be movedin a direction toward the ads of the target throwing armto permit sprin 47 to return the target throwing arm to latched position.-
It will also be understood that the target throwing spring acts in opposition to the weaker spring 2'? so that when the target throwing arm is given an axial movement spring 47 willserve as a cushion and shock-producing member having its primary action toward the end of the target throwing movement of. the arm.
t will also be seen that during the target throwing action of the device the latter will be oscillated back and forth and at a predetermined angle.
