Application January 9, 194'7, Serial No. 721,079

My invention'relates to new and useful improvements in machines for making archery targets. y I

The primary object of the invention is to provide a machine for forming such targets of convolutions of fabric and straw wound with the straw compressed and the convolutions tied together by sewing through the same, all to the end of obviating manufacturing such targets solely by hand.

Other objects together with the advantages to be derived in the practice of my invention will become apparent when the following description and claims are read with reference to the drawings accompanying and forming part of this specification.

Figure 18 is a view in horizontal section taken on the line l8l8 of Figure 3.

Referring now to the drawings in detail, wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a frame having a trough 6 supported thereon adapted to con tain straw l of a type generally employed for building archery targets. At the front end of the frame 5 is an upstanding frame structure 8,

which includes a pair of spaced parallel, vertical frame members 8 of channel shape in cross-- section and forming guides in which the side edges of a floating mandrel frame 9 are positioned for vertical sliding movement.

A frame structure In projects laterally from one side of the framet adjacent the front end of said frame 5 for a purpose presently seen.

At the rear end of the frame 5 is rotatably supported a roll of burlap II or other fabric in strip form, the burlap extending forwardly along the bottom of the trough 6 with its free end clamped between the longitudinally split mandrel I2 having its ends journaled in hinged hear ing brackets i3 secured to the upright members 9 of the floating frame Q. The bearing brackets l3 are hingedin any suitable manner for opening to remove and replace the mandrel 12 for T a purposepresently seen.

Ono'ne end of the mandrel I2 is secured a ratchet it operatively engaged by a pawl 15 pivoted on an arm I6, one end of the arm bein pivotally supported on the mandrel, and the other end of the arm having an actuatingrod ll" pivoted thereto. The actuating rod ll extends rearwardly of the machine and has its rear end eccentrically connected as at H to a Wheel 18 secured on a shaft l9 journaled on the upper edges of the trough 6 and extending transversely thereof. The shaft [9 is driven by means of a sprocket 2E! and chain 2! from a small sprocket 22 secured on a shaft 23 journaled on the lower portion of the frame 5, the shaft 23 also having a large sprocket wheel 24 secured thereto, driven by a chain 25 from a smaller sprocket 26 on a clutch device 21 also journaled on. the lower portion of the frame, the clutch device including a pulley 28 driven by a belt 29 from an electric motor 30. The clutch device 2'! may be of any conventional type adapted to be engaged as by a pull chain 20. For exerting pull on the chain 26' a foot pedal 2I is pivoted as at 22', on a post 23 on the frame and is operatively connected by a link 24' to one end of a rocker bar 25' pivoted as at 26' on an upright 21 on the frame 5, the other end of said rocker bar 25 being operatively connected as at 28' to said chain 20.

An eccentric 3I is also secured on the shaft I9. Connected at its rear end to the eccentric 3I is a lower feed arm 33which is of a width substantially equal to the width of the trough 6 and rests on top of the straw I overlying the burlap I I in the trough 6 therein for reciprocation by the eccentric 3|. The connection between the feed arm 33 and the eccentric 3| takes the form of a grooved cap bearing 29 bolted together, as at 36, with the eccentric 3I rotatably confined therein and suspending the same, said lower feed ings I3, the sections of the split mandrel I2 may be separated for inserting the burlap I I therebetween to be clamped by said sections.

The frame structure I0 includes an upper horizontally extending channel-shaped guide member 44 in which a needle-actuating block 45 is slidably positioned having one end of a needle 46 secured thereto, the needle having a notch 41 at its outer end and being adapted to be advanced and retracted transversely through the target, the notch 41 serving to pull a sisal thread 48 through the target for tying the convolutions I thereof together.

arm 33 being secured by screws 3| to thebottom:

of the bearing 29', as best shown in Figures 16 and 1'7, so that said arm is swingable vertically about said eccentric with its front end adapted to rest, under the influence. of gravity, on the straw I in the bottom of the trough 6. As will be clear, the eccentric 3| is revolved by the shaft I9 in the bearing 29' to. reciprocate said lower feed arm 33 so that the front end of said arm 33 intermittently rams and packs straw I between the lowermost completed convolution of the target being formed and the succeeding one being wound on the completed one. The arm 33 is inclined downwardly and forwardly in the trough G and adjacent its frontend is provided with a weight 34 adapted to cause said front end to compressthe straw in the bottom of the trough 6 and'the front end of the arm. 33 is provided with a seriesiof upstanding, forwardly inclining spikes or teeth 35 adapted to engage the lowermost completed convolution of the target 36 as the same is wound on. the" mandrel to thereby assist in rotating'the target. As will be-apparent from an inspection of Figure 9 of the drawings, the teeth 35'are inclined in a direction to disengage themselves upon a rearward movement of the arm 33. Forwardly and downwardly inclined spikes 32 depend from the lowerfeed arm 33 along the rear end portion thereof for feeding the straw I forwardly as said arm 33 is reciprocated. The straw is thus fed on top of the burlap toward the front end of the trough 6 to be-wound iniayers on the, mandrel I2.

An upper arm 31 (similar to the arm 33-) is also employed'for assisting in the rotation of the; tar,- get. The front end of the arm 31 is provided with a hinged vertically swingable head 38thereon'jhaving depending rearwardly inclined teeth 39-for engaging the 'upper edge of the target, the rear'end'ofxthe arm being hinged'as at 33' to the upper end of'an oscillating rod 46 pivoted intermediate its ends, asat M, to an upstanding support 42 on the-frame 5, thelower end of the rod being pivotally connected as at 40' to a link 43pivota1ly connected as at 43' to the lower arm 33 whereby to provide asimultaneous operating connection between thearms'33 and3I arranged so that said arms are oppositely actuated.

As will be understood, the mandrel frame 9 rises as the convolutions of straw I and burlap II are wound on the mandrel I2 and the target is thus increased in size, said target engaging the bottom of the trough 6 and thereby raising said frame. The winding operation is started with said frame 9 lowered so that the mandrel I2 is spaced from the bottom of the trough 6 by only the thickness of the front end of the burlap strip inserted in the mandrel. By opening the bear- The block 45 and needle 46 are reciprocably actuated by means of a pitman rod 49 pivotally connected at one end to a pin 50 carried by the block 45, the other end of the pitman arm being pivotally connected, as at 5!, to one end of links 52 having its other endpivoted as at 53 to a part of the frame I6. The pitman rod 48- is of channel shape in cross-section and slidably mounted therein is a block 54 eccentrically connected to one face of a pulley 55 driven by a belt 56 and a pulley 5'! from a transmission unit, designated generally at 58, supported .at the lower end of the frame structure I I]. The pin 50 is passed through a bushing 44 fixed in the pitman rod 49 and extending through a filler block 45' suitably fixed in said rod 49. A roller 46 is provided on the outer end of said pin 56 for a-purpose presently seen. Suitable gaskets i'l, 48 are provided on the pin 56 between the bushing 44' and the block 45 and roller 46'. The transmission unit' 58 is driven by means of a pulley 59 and belt 66 from a motor 6|, mounted at an intermediate portion of the frame structure ID. The transmission unit .58 preferably comprisesa. worm shaft 58' on which the pulley 59 is fixed and which drives worm gear 59 on across shaft'fill' onwhich the pul ey 51 is fixed.

The motor BI is controlled by a clutch device 62 which includes a pivoted arm 63' having the lower end of a chain 64 attached'to the free end of the arm, the chain having its upper end attached to an arm 65 extending horizontally outwardly from a locking lever 66-pivoted at 6.'I adjacent one end of the lever to the-frame structure I0, the lever having a notch 68 formed in its lower edge adapted for receiving the roller 46 on the pin 56 of the slide block 45 of theneedle-to stop operation of said needle in aretracted position thereof.

Also attached to the lever 66, adjacent its free end, is a manually controlled rod 69 which ex tends downwardly and has its lower end connected to the rear end of a foot pedal ID. The pedal I0 is pivoted at II to the bottom portion of the frame structure Ill and is adapted, upon'a depressing movement of the outer end of the pedal to raise the lever 66 upwardly to disengagethe notch 68 from the pin50 and permit free operation of the needle. A coil spring I2, also attached adjacent the free end of the lever 66' assists in returning the same downwardly for engagement with the pin 56. An upward movement of the lever: 66 will also'raise, the clutch control-lever 63 to engage the clutch and thus operatively conheat the needle with the motor. A suitable guide 66' is provided on the frame II! for the free end of the locking lever 66.

The needle 46 is threaded manually, in its'fully retracted position, with short lengths, successively, of thread 48 looped intermediate the ends thereof, as shown in Figure 10, across. the needle through thenotch 41. As the needle 46 advances;

.ure 13.

it thrusts the length of thread 48 thereon through the target in looped form, as best shown in Figures. 10, 11 and 13, with the ends of the thread free on the near side of the target. At the 'end of the advance stroke of the needle 46, a loop of the thread 43 is formed. on the far side of' the target and left there, when the needle 46 is retracted, the loop resting on the upper edge, as shown at 13, of a V-shaped bracket 14 and in position to be engaged by one of a plurality of traveling hooks 25 carried on'an endless belt 16 traveling over pulleys ll, 18, asshown in Figure 11. The pulley H is fast on a shaft 19 driven bya pulley 80 and belt 8! from an electric motor 82. The hook l5 engaging the loop 13 of the thread 48 pulls the loop out and one end of the thread 48 through the target to fall off the hook, at which point said end is grasped by the operator and manually wound under the lowermost convolution of the target and then threaded through the eyed! of the needle 46 to extend across the retracted needle, all as shown in Figure 13, and bethrust inloop form through the target as the needle 45 again advances, to again leave a loop on the far side of the target to be pulled out by one of the hooks l5. Thus, the length of thread 48 is stitched around each outermost convolution of the target, as shown in Fig- As a stitch is thus formed, the end of the thread 48 pulled through the target by a hook 15 is manually wound around. a snubbing spool 83 fast on the shaft 19 and held fast by hand, for an instant, so that by friction the stitch is pulled tight, after which the end is passed under the lowermost or outermost convolution of the target to the near side and the needle 46 threaded therewith as previously described. When one length of thread 48 has become substantially used up, another length is tied thereto to be threaded on the needle 46.
