Ind., assignors to Meilott Arrow Crest, Ina, a corporation of Indiana Filed May 6, 1959, Ser. No. 811,462 6 Claims. (6!. 118-5il3) The present invention generally relates to a machine for cresting arrows and more particularly to such a machine which will crest in an accurate manner a multiplicity of arrows or a single arrow in a most expeditious manner.

As is well known, archery arrows are crested or striped with paint in certain color combinations for identification of the arrows. In other words, each user will have a particular color combination on all or" his arrows. Since the color combination usually involves a multiplicity of stripes of difierent colors arranged in different orientations which stripes must be applied to the arrows in a neat and expeditious manner, it is the primary object of the present inventionto provide a machine for accomplishing this purpose with the expenditure of a minimum amount of time while greatly improving the quality of the stripes or crest.

Another object of the present invention isto provide an arrow cresting machine incorporating structural features for securely engaging the mock or" the arrow to drive or rotate the arrow at a positive speed and to assure that the arrow will run true when driven.

A further object of the present invention is to provide an arrow cresting machine including a tail stop assembly which carries the points of the arrow in a cup while the arrow is rotating with there being a low tension spring pressing the cup onto the point of the arrow.

Yet another object of the present invention is to provide an arrow cresting machine having a stabilizer arm for preventing run out of the arrow.

Yet another object of the present invention is to provide an arrow cresting machine including adjustable pointers and a color card indicator for indicating the relation and position of colors in the crest thereby permitting various crests to be formed by merely varying the orientation and position of the paint applying figures.

Another very important object of the present invention is to provide an arrow ere-sting machine including a head and tail movable towards each other for receiving arrows and with the rotation of the arrows after striping preventing the paint thereon from running.

These together with other Objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 12 is a perspective view of the color card holder platform.

Referring now specifically to the drawings, the numeral 10 generally designates the arrow cresting machine of the present invention which includes generally a powered rotatable head stock 12 and a tail stock 14. The machine 10 includes an elongated base plate 16 having two upstanding

end support brackets

18 and 20 which may be of any suitable form and construction and each of which includes a tubular bearing 22 at the upper end thereof.

The head stock 12 includes a substantially circular plate 24 mounted on an elongated shaft 26 which extends between the bearings 22 and is rotatable therein. The plate 24 is rigidly affixed to the shaft 26 and is spaced from the bearing 22 by a spacer 28 which may be held in position by a setscrew with the spacer 23 and the hub of the plate '24 being held in position by set screws or similar suitable fastening means. Also, the plate 24 may be provided with openings or lightening holes if desired.

The periphery of the plate 24- is provided with a plurality of radially extending ledges or abutments 30 which form the notches or latches on a rachet wheel in which the plate 24 becomes a ratchet wheel for engagement with the projecting lug 32 on an adjustable catch or latch 34 carried on an upstanding rod 36. The catch or lug 34 is secured in adjusted position by setscrews 38 or the like. The upper end of the rod 36 is provided with a handle 40 and the lower end thereof is provided with a horizontal rod 42 extending perpendicularly to the upstanding rod 36 with the rod 42 being journaled in "bearing blocks 44 whereby manual manipulation of the handle 4% may cause the rod 36 to swing inwardly and outwardly towards the periphery of the plate 24 thereby bringing the projection- 32 into engagement with the abutments 30 on the plate 24 thereby locking the plate 24 from movement in one rotational direction but permitting movement of the plate 24 y in the other rotational direction. A tension coil spring as is provided for urging the rod 36 towards the periphery of the plate 24 thereby assuring that the projection 32 will engage the abutments 39 whereby this structure acts as a ratchet gear and dog assembly enabling rotation of the plate 24 normally in one direction but permitting manual release of the catch 34 so that the plate 24 may be rotated in the other direction of rotation.

Mounted at circumferentially spaced points on the plate 24 is a plurality of stub arrow drive shafts 48 extending through a rotatable sleeve 50 received in an opening 52 extending through the plate 24. One end of the sleeve 50 is engaged by a V-belt pulley 54 aflixed to the outer end of the shaft 48 by a setscrew 56 or the like. The other end of the sleeve 50 is enlarged as illustrated at 58 and rigidly secured to the shaft 48 by setscrew 60. As shown in FIGURE 2, the inner end of the shaft 48 is recessed within the enlarged end 58 of the sleeve 50 and includes a longi- 'V-belt 68 driven from a power output V-beltpulley 7% connected with an electric motor 72. The V-belt 68 is entrained over the plurality of pulleys 54 for causing rotation of all of the pulleys that it engages in the same direction. The motor 72 may be mounted in any suitable manner on the base 16 for adjustment for maintaining tension on the belt 68. A majority of the shafts 43 will berotated thus rotating a majority of the arrows 66 so that the striped paint or crest 74. does not run and after the arrows have been rotated for a-predetermined length of time, they will not be rotated when they reach a position so that the associated pulley 54 is not in engagement with the drive belt 68. The time element of drying of the painted stripes is more or less controlled by the dexterity of the person operating the machine by placing in uncrested arrows and for setting up the desired color combination.

The tail stock 14 includes a circular plate 76 having a central hub 78 slidably received on the shaft 26. The

shaft 26 includes a plurality of projections 3b disposed in longitudinally spaced relation thereon which projections '80 are received within a longitudinal groove 82 in the hub 78 thereby precluding relatively rotational movement between the shaft 26 and the tail stock plate 76 whereby the plate 7 6 will rotate at the same speed as the shaft 26 and also at the same speed. as the plate 24 or head stock. Means interconnects the plate 76 in the shaft as for retaining the plate in longitudinally adjusted releasable position. This means includes a block 84 secured to the plate 76 by a fastener 86. The block 84 carries a finger actuated or manually actuated plungerss which is spring urged by spring fitlinto the area between adjacent projections or teeth8t) as illustrated in FlGURE 2. Thus, the spring 90normallyurgesthefree endof the plunger 88 into engagementwith the lugs 89 thereby locking the plate %6 Y in longitudinally adjustedlpo sition so that the. machinemay receive arrows of diiferent lengths. The bearing 22 which receives the shaft 26 is provided with an abutment or thrust washer 92 to assure that no excessive wear is made on the bearing housing 22. Also, the cylindrical bearing 22 may be provided with a suitable lubrication cup 9'4 which is also desirable in the bearing 22 at the head stock endof the device.

Disposed in circumferentially spaced relation is a plurality of tubular members $6 received in opensing 98 in the plate 76. The tubular members as are releasably and rigidly secured in position by a releasable manual handle 100. The cylindrical and tubular member $6 is provided witha spring 1% engaging the inner end of a piston or plunger 164 which has a projection 1th; slidable in a groove 103 which prevents rotation of the shaft or stem 104 in relation to the cylinder or tublar member 96.

The inner end of the stern ltlvis provided with a cup shaped bearing 11% rotatably receiving the shank 1120i engaging one of the abutments 3fi which prevents rotation of the plate 2 until such time as the painting operation on an arrow has been completed so that the handle 42 may be grasped and the catch 32 released thereby per- .iitting the wheel 24 to rotate one notch for bringing another arrow into registry with the mechanism which applies the paint and points as to the desired areas to be painted which structure is generally designated'by the numeral 129. Mounted on the shaft 26 is a pair of-collars 1'22 and 124 which are rotatable on the shaft 26. A pair of ihred collars 126 are disposed on opposite sides of the collar 124 to prevent longitudinal movement thereof. Each of the

collars

122 and 124 is provided with radially extending arms 12% in which two of the'arms are substantially perpendicular to each other and receive weights 139 on the outer ends thereof. The third arm 128 is provided with a fitting 132 on the outer end thereof. The adapters 132 are interconnected by an elongated rod 134 which receives a plurality of pointers 136 thereon which pointers 136 are retained in longitudinally adjusted posi tion by setscrews 138. The outer ends of the pointers 136 are pointed as indicated by the numeral 140* and will engage or substantially come into contact with the arrow 66 for pointing out the limits of the various diiferent colors and for so applying the annular rings of color if desired. This construction enables a predetermined crest to be set up by varying the number and spacing of the pointers. The rotational feature of the

collars

122 and 124 enables pointers 136 to be movable about the axis of the shaft 26 with the weights 13tlacting as counterbalances to retain the rod 134 in desired position.

Supported from the base 16 is a pair of upright brackets or supports 146' rigidly interconnected by a hand. rest 142 which is horizontally disposedland which is provided with a rounded top surface with the inner edge thereof being cut out as at 144 for receiving the arrow fietching 146 without damaging the construction of the arrow.

Carried by the rest 142 at the end thereof remote from the head plate 24, there is provided a bearing bracket 148 aving a pivot bolt 35% extending therethrough which pivot bolt also supports a block 152 slidably receiving an elongated lunger or rod 154 and which is slidable through the block 152. The block 152 is held on the bolt 15%" by a knurled nut 156. The outer end of the plunger 15% is provided with a handle 158 and a spring 159 urges the plunger 154 outwardly. The inner end of the plunger 154 is provided with an adapter or saddle. 160 for engagement with the arrow 66. By an inward movement of handle 158 saddle loll engages arrow 66 thereby correcting any runout of arrow 66 and giving the arrow a three point support. Upon operators release of handle 158 spring 159 disengages saddle from arrow permitting posi- V tioning of the next arrow to be crested.

' biased alligator clip.

a cup shaped member 114 receiving the pointed ends of v the arrows 66. The member 114 is journaled in the hearing cap 110 by a bearing 116 and the pointed end of the 'arrow 66 is received in a generally conical socket 118.

With the invention as thus far described, a plurality of arrows 66 are held in position by the spring 102 resiliently urging the socket 114" to grip the arrow 66 with the nook end thereof engaged with the drive flange 62.

As the motor 72 is energized and drives the plate 24 in a clockwise direction as viewed from the right hand end of FIGURE 1, the V-belt pulley will cause rotation of all of the pulleys 54 that itrco'mes into contact with and will also urge and tend to rotate the plate 24 in the same clock wise direction. Such rotation is prevented by the lug 32 A supporting platform 162 having depending pivot lugs 164 thereon is received on the rod 134. The platform 162 receives a color card 166 which is held thereon by a spring clip 16% having the usual operating handles'17t} and this construction may be in the nature of a spring In the present invention, the shaft 48 is so constructed that the nook end of the arrow 66 will be driven at a relative speed and will true when driven. The enlarged member 58 which is in the form of a chuck prevents the arrow from disengaging when the arrow is bowed with the drive mechanism turning a multiplicity of arrows after they have been painted to prevent the paint from running. Manual operation of the device permits movement of the arrow in a circular path about the center of shaft 26 when the catch 34 is released from the abutments. The tail stock assembly carries the point of the arrow in a cup while turning. The angle of the socket in the cup is constructed to fit the point of the arrow.v The spring 102 is relatively weak and is of four pounds spring tension with this spring tension being variable and the above mentioned figure being only representative. The thrust bearing 116 journals the cup and allows the same to turn with low resistance and the tubular cylinder 96 is provided with a flange engaging the inner edge of the plate 76 for retaining this assembly in position.

The stabilizing arm or plunger 154 mounted on the hand rest table is held in a retracted position by the spring 159 thereon. When the arrow is turning and the saddle 160 moved against the arrow, all run out of the arrow is corrected and the arrow is positioned for easy striping. Only a very small scope of movement of the saddle 160 is necessary to engage the arrow. The adjustable pointers or color card clipped to the platform indicates the rela tion and position of the colors in the crest and this assembly swings freely on the shaft 26. The counterweights 130 are adjustable to orientate the pointers or the color card to position the same directly in alignment with the arrow to be striped.

The various structural details enable multiple application of cresting to arrows and the head stock wheel or plate is notched to lock each arrow in position for striping. The tail plate is moved nearer or further from the head wheel to accommodate various length arrows and is held in position by the plunger and lugs as shown. When the machine has 12 arrows therein, cresting proceeds on each successive arrow by rotating complete assembly in supports at the ends thereof which is accompilshed by releasing the catch from the lugs or abutments and either manually operating or rotating the assembly for providing a specific power drive for this purpose. After the pointers or color card indicate the position of the colors in the crest, the paint may be easily positioned thereon while using a simple applicator and while resting the hand on the hand rest thereby providing a neat cresting operation.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, aud accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
