WILEY H. PRIDG-EN, OF CREEK, NORTH CAROLINA.

Specification of Letters Patent.

Patented May 11, 1915.

Application filed March 19, 1914.. Serial No. 825,894.

To all whom it may concern:

Be it known that I, WILEY H. PRIDGEN, a citizen of the United States, residing at Creek, in the county of Warren and State of North Carolina, have invented a new and useful Machine for Heading and Boring Basket-Bottoms, of which the following is a specification.

This invention relates to machines particularly designed for producing the wooden bottoms of fruit baskets and the like,-the same being more particularly designed as an improvement upon the structure disclosed in Patent No. 1,033,732 issued to me on July 23, 1912.

One of the objects of the present invention is to provide improved means for feeding the stock to the circular cutter, said feeding means being so mounted and constructed as to grip firmly upon the side edges of the stock and being quickly shiftable so as to enable stock of different widths to be placed in the machine.

A further object is to provide improved means for actuating the feed rolls.

Another object is to provide a novel form of circularicutter whereby the bottoms are formed from the stock, said cutter constituting means for ejecting the bottoms therefrom and for perforating the bottoms;

YVith the foregoing and otherobjects in 7 view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and 1n the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawingsthe preferred form of the invention has been shown.

In said drawings :,Figure 1 is an elevation of the feed end of the machine. Fig. 2 is an elevation of the discharge end of the machine. Fig. 3 is a longitudinal section on the line A-B Fig. 2, the spreaderoperating foot lever being removed. Fig. 4 is an en'- larged section through a portion of the machine on the line CD Fig. 1. Fig. 5 is an' enlarged section through the circular cutter and its pulley, the said section being taken on the line EF Fig. 2, the bearings and the shaft of the cutter being shown in elevation. Fig. 6 is a detail view of a cam used for the purpose of actuating the cutter upwardly and downwardly. Fig. 7 is an enlarged section through the cushion used in connection with the cam actuated rod, said section being taken on the line GH Fig. 3, the rod being shown in elevation. Fig. 8 is a detail view of a one piece bottom such as produced by the machine. Fig. 9 is a detail view of a two piece bottom produced by the machine.

Referring to the figures by characters of reference 1 designates the side supports of the machine, there being a feed table 2 supported upon the front portions of these side supports and a cutting table 3 mounted on the rear portions of these side supports, the two tables 2 and 3 being spaced apart at 4: so as to receive between them the upper portion of a lower feed roll 5 preferably formed with longitudinal corrugations or serrations. Side pieces 6 extend upwardly from the cutting table 3 and extend across the ends of the opening 4t so as to form guides for bearing boxes 7 in which is journaled a transverse shaft 8 carrying a feed roll 9 similar to the roll 5. These bearing boxes 7 are constantly pressed downwardly by springs 10 so that the roll 9 is normally supported close to or in contact with the roll 5. The shaft 11 to which the roll 5 is secured has a gear 12 and this gear meshes with a gear 13 revoluble with the shaft 8. The teeth of the gears are so proportioned that, although a limited verticalmovment of the roll 9 is permitted, the two gears 12 and 13 will remain constantly in mesh.

Extending along one side portion of the feed table 2 and projecting over the opening 4 and lapping the cutting table 3 is a stationary guide 14 and adjacent the front or feed end of this guide is j ournaled a vertical shaft 15 to the upper endof which issecured a feed roll 16 having an annular flange 17 at the top thereof, the innermost portion of the roll 16 being in line with the inner face of the guide 14: while the flange 17 projects inwardly beyond said lines. Shaft 15 is supported by a bracket 18 secured under the feed table 2 and the lower end of the shaft is provided with a bevel gear 19 constantly meshing with a gear 20 secured to a transverse shaft 21 on which a larger gear 22 is secured. This gear 22 meshes with a gear 23 which, in turn, meshes with a gear 24 enga ing the gear 12. A small gear 25 rotates with gear 24, and receives motion from a gear 26 mounted for rotation on a shaft 27,

there being a ratchet wheel 28 revoluble with the gear 26. This ratchet wheel is spaced from the gear 26 and interposed between the ratchet wheel and the gear is a rod 29 carrying a spring pressedpawl 30 which normally engages the ratchet wheel, said pawl being journaled on a bearing pin 31 supported at one end by the rod 29 and at its other end by an ear 32 extending from a ring 33 which is mounted for rotation on the shaft 27. The lower end of rod 29 is formed with a head 34 in which is provided a longitudinal slot 35. A transverse shaft 36 extends through the slot and carries a cam or eccentric 37 constantly engaged by a roller 38 carried by the head 34. A spring 39 serves to hold this roller 38 in engagement with the cam or eccentric. A gear 40 rotates with shaft 36 and meshes with a gear 41 secured to the drive shaft 42, there being a pulley 43 or the like upon the said shaft whereby the shaft may be driven by a belt or the like.

A bevel gear 44 is feathered on the shaft 21 adjacent that end thereof remote from gear 20 and moves with a hanger 45 depend ing from a slide 46. lhis slide is supported by parallel cleats 47 secured to a bracket 48 depending from the feed table 2, these cleats being parallel with shaft 21. A sleeve 49 extends upwardly from the slide 46 and journaled in this sleeve is a vertical shaft 50 to the upper end of which is secured a feed roll 51, similar to the roll 16 and projecting downwardly into a slot 52 formed in the feed table. A gear 53 is secured to the lower end of shaft 50 and constantly meshes with gear 44.

A spring 54 is secured at one end to the sleeve 49 and at its other end to a cross strip 55 which connects the brackets 48 and 18,

this spring serving to hold the roll 51 pressed normally against the inner end of the slot 52.

Pivotally connected to the bracket 18 is a link 56 and another link 57 is pivotally connected to the sleeve 49. These links are pivoted together to form a toggle and extending downwardly from the connected ends of the links is a rod 58 the lower end of which is connected to one end of a foot lever 59 fulcrumed as at 60. The other end of the lever has a foot plate 61. Obviously when this foot plate 61 is depressed, the toggle made up of the links 56 and 57 will be extended so as to shift slide 46 laterally away from the gear 19' so as thus to elongate spring 54.

should the spring 54 be insufficient to clamp stock between the rolls 16 and 51 with a desired pressure, this lever 62 can be utilized to force the sleeve 49 toward the roll 16.

From the foregoing description it will be apparent that when the drive shaft 42 is rotating motion will be transmitted therefrom to the shaft 36 in the manner described and, consequently, the rod 29 will be reciprocated so as to cause pawl 31 to impart an intermittent rotation to shaft 27. The gears constituting means for transmitting motion to the feed rolls 5 and 9 and to the rolls 16 and 51 will be given an intermittent rotation. When the foot plate 61 is depressed, roll 51 will be shifted away from roll 16 and the stock to be cut is then placed on table 2 between the rolls after which the foot plate 61 is released and roll 51 is caused to shift back toward its normal position, thus engaging one edge of the stock and forcing the other edge of the stock against the roll 16. Consequently, during the rotation of the rolls, the stock will be fed forward into the pass between the corrugated rolls 5 and 9. These rolls will, in turn, engage the stock and feed it positively onto the cutting table 3. As the upper roll 9 is mounted in slidable bearings it will be seen that said roll will shift upwardly or downwardly so as to accommodate itself to stock of any thickness.

After the stock has been supplied to the cutting table 3 it is adapted to be cut up into basket bottoms, heads or other devices of a predetermined size. For this purpose cutting mechanism of novel form is utilized. By referring to the drawings it will be seen that the side strips 6 support a cross strip 63 on which is arranged a standard 64 having a vertical shaft 65 journaled thereon and mounted to rotate and to slide longitudinally. A pulley 66 is feathered on the shaft and is held against up and down movement by the standard 64, there being a recess 67 in the standard into which the pulley projects.

Thelower end of the shaft 65 is reduced to form an annular shoulder 68 against which is fitted the circular head 69 of the cutter. This head is fitted snugly within one end portion of a saw 70 which is in the form of a hollow cylinder, the other end of the saw being toothed, as shown at 71. Longitudinal slots 72 are provided in the saw for the reception of clamping bolts 73 which enter the head and which, when tightened, hold the saw against movement relative to its head 69.

A bearing member 74 is secured to the cross strip 63 and journaled therein is the upper end portion of a sleeve 75 mounted for rotation with the shaft 65. This sleeve 75 extends upwardly from a disk 76 disposed above the head 69 and having rods 77 extending downwardly therefrom and through openings 78 in the head 69. An ejecting disk 79 is provided at the lower ends of the rods 77, these rods serving to connect the ejecting disk to the disk 76. Said ejecting disk fits snugly within the saw 7 0 and its upper face is preferably hollowed outlas shown at 80 to reduce weight while its lower face is fiatso that a circular bearing 81 is thus provided upon the bottom of the ejecting disk. A central opening 82 is formed in the disk 79 and extending'from the end of the shaft 65 is a bit 83 adapted to extend into the opening. The free end of the bit is disposed in substantially the same plane with the free ends of the saw teeth 71. The bit 83 is held in place by a lock nut 8% which is adapted, during the boring operation, to enter the opening 82 and close it, thus preventing shavings or the like from enteringthe space between the head 69 and the ejecting disk 79. The head 69 may be held upon the shaft 65 in any suitable manner, as by means of a binding nut 85. It is to be understood that the hearing 7 4: holds the sleeve 75 and the parts con nected thereto against up and down movement with the shaft 65 and the saw 70.

Secured to the upper end portion of the shaft 65 is a collar 86 having an annular groove 87 in which is fitted a ring 88 provided with trunnions 89. Pivotally mounted on these trunnions is a ring 90 carried by the intermediate portion of a lever 91, said lever being fulcrumed at one end upon a standard 92. The other end of the lever is pivotally connected to a rod 93 which extends downwardly into a sleeve 94 and is provided with a head 95 against which bears one end of a coiled spring 96. This spring extends around the rod 93 and bears at its other end against a cap 97 secured to one end of the sleeve 94. Secured to the other end of the sleeve 94 is a rod 98 which extends downwardly and is provided with a head 99 from which extends a pin 100 adapted to work within a cam groove 101 formed within a disk 102. This disk is secured to the shaft 36 and the cam is so shaped that, during each rotation of the shaft 36, the rods 98 and 93 and the lever 91 will be quickly moved upwardly and then be used, it merely being necessary to disengage the ejecting disk, and detach the head 69 after which a larger or smaller saw can be placed in position. The table 3 is removably mounted and, consequently,tables with grooves registering with the saw used can be substituted.

It is to be understood that the shaft 65 is rotated continuously but the saw is normally elevated with the ejecting disk 79 projecting therebelow as shown in Fig. 5. After the stock has been fed to. position under the saw, the cam disk 102 operates automatically to slide the shaft 65 downwardly in properly timed relation so that the saw will thus move downwardly below the disk 7 9, thus bringing the teeth 71 into engagement with the stock and at the same time causing the bit 83 to enter the stock. A round bottom such as shown at 105 will thus be produced, the same being formed with a central opening 106. During this cutting and boring operation the nut 8% closes the opening 82 so as to prevent sllgavings and dust entering the space above t e ejecting disk 79. As soon as the stock has been cut, the cam elevates the shaft 65 and saw 70 while the ejecting disk 79 holds the bottom 105 down on the table. During the sawing operation the parts are of course operating at a high speed and, consequently, as soon as the saw has been withdrawn from the stock, the bottom produced will be thrown outwardly from the machine, said bottom striking a guide cleat 107 which is secured upon one side portion of the table 3 and which serves to guide the bottom out from the end of the machine. To prevent injury to the operators, a hood 108 is preferably erected over the machine adjacent the saw.

In order that the bottom may be made of pieced stock, as shown in Fig. 9, a stapling machine of any preferred construction may be combined with the feeding and cutting mechanism herein described. This stapling machine has been indicated generally at 109 and is carried by standards 110 extending downwardly beyond the side supports 1. Inasmuch as the stapling mechanism constitutes no part of the present invention, it is not deemed necessary to describe or illustrate the same in detail. It need merely be stated that the mechanism can be operated in properly timed relation by means of cams or eccentrics 111 mounted on the shaft 36 and which transmit motion through a rod 112 to a pawl 113 and a ratchet wheel 114i forming a part of the stapling mechanism. A cross head 115 is adapted to be reciprocated vertically by rods 116 and cams or eccentrics 117. As before stated, however, the stapling mechanism does not form any part of the present invention and, consequently, need not be described in detail. The stapling mechanism is desirable, however, as by the use thereof it becomes possible to piece together the stock, as shown in Fig. 9.

The central openings formed in the bottoms are used for the purpose of holding them on the basket forms while the makers are nailing the veneer on in forming the baskets, and in the case of heads for other purposes such as round crates, etc., are often used as a convenience in stringing a quantity together to facilitate handling.

It will be noted that the ejecting disk has an annular flange fitting snugly within the saw so that each time the saw cuts into the stock, the dust will accumulate between the saw and under the flange and, when the saw is raised, this accumulated dust will be thrown away. The flange prevents the dust from working up into the saw.

What is claimed is 1. A rotating cylindrical saw for cutting disks from the stock, an ejecting disk surrounded by the saw and adapted to engage the stock during the movement of the saw into and out of the stock, thus to clamp the stock and to eject the cut disk from the saw, said ejecting disk having an annular channel for the reception of sawdust during the cutting operation.

2. A rotating cylindrical saw for cutting disks from the stock, an ejecting disk surrounded by the saw and adapted to engage the stock during the movement of the saw into and out of the stock, thus to clamp the stock and to eject the cut disk from the saw, said ejecting disk having an annular channel for the reception of sawdust during the cutting operation, there being a central opening within the ejecting disk, a boring element movable through said opening and into the stock during the cutting of the stock, and means for closing the opening in the ejecting disk during the operation of the boring element.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signa ture in the presence of two witnesses.
