JAMES H. REED, OF LYNN, MASSACHUSETTS.

WOOD-WORKING MACHINE.

- SPECIFICATION forming part of Letters Patent No. 467,629, dated January 26, 1892.

Application filed July 1,

To all whom it may concern.-

Be it known that I, JAMES H. REED, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in lVood-Working Machines, of which thefollowing is a specification.

My invention relates in general to woodworking machines of the class designed for cutting out disks or circular forms, like barrel-heads, tub and pail bottoms, and the like.

In particular my invention relates to the devices for presenting to the cutter-heads employed in such machines the material from which the disks are to be produced. My present invention, mainly, is designed as an improvement upon that shown, described, and

claimed by me in an application filed November 28, 1890, Serial No. 372,777. In the said application I have presented a machine for the purpose above stated having two cutterheads mounted on revolving vertical tubular shafts or sleeves, the said shafts or sleeves being connected with operating devices, whereby they may be moved longitudinally in such manner as to carry the cutters mounted on the cutter-heads into contact with the material to be cut. Rods or shafts extending through the said tubular shafts or sleeves carry clamping-plates, and the upper of the said rods or shafts is connected with operating devices, whereby it may be moved to clamp the material to be out between the upper clamping-plate and. the lower clampingplate. In addition to the said clamping devices and cutting devices, the machine comprises devices whereby, when the clamping and cutting devices are separated, to intermittingly feed forward the planks or boards from which the disks are to be out. The machine presented in the application aforesaid is designed for cutting out disks from planks or boards which are fed forward intermittingly to the clamping and cutting devices, as just mentioned.

The design of my present invention is to provide for feeding forward successively to the disk-producing devices of a machine on the order of that just referred to short sections or blanks instead of long boards or planks, and also to provide for presenting such short sections properly to the disk-producing devices.

1891. Serial No. 398,118. (No model.)

My invention will be described in connection with the accompanying drawings, and then be particularlypointed out in the claims at the close of this specification.

In the drawings, Figure 1. is a view in side elevation of portion of a wood-working machine of the kind referred to, the same having applied thereto one embodiment of my present invention, sut'ficient of the machine being shown to illustrate the relations and connections'of the invention. Figs. 2 and are views in end and side elevation of parts concerned in operating the movable gage hereinafter described. Fig. 4 is a sectional plan view of the parts shown in Fig. 1, with the upper part of the clamping and cutting devices shown in the said figure removed. Fig. 5 is a view in section on the dotted line at 00 in Fig. 4:.

plication aforesaid, and in practice the parts lettered 72/, 7c, 8', w, and i will be actuated by operative connections such as those presented in the said application. In the application aforesaid the rack 7o is shown connected with devices serving to feed forward intermittingly long planks or boards to the clamping and cutting devices, the said devices co-operating with the devices for supporting and guiding the said planks or boards. In my present invention I connect with the rack a pusher by which to push or carry forward successively into the clamping and cutting mechanisms short sections of boards or planks, and adjacent to thesaid pusher I arrange a trough, chute, or the like receptacle, in-which a number of such sections may be placed, the pusher serving to propel or carry them forward one by one, to the clamping and cutting devices; Such a pusher is shown at 3, it consisting of a flat board, plate, or strip herein shown as resting and sliding upon transversely-arranged rollers 4 4, mounted on table D,the said pusher'being provided at-its outer end with across-strip 5, which at its ends is connected by rods 7 7 toaslide 8, to which the rack 76 is secured or connected.

- In thedrawingsl have shown a receptacle or box 9. placed above the rollers 4 4, boards 0 10 10 being used to bridge and fill the open.-

ings between the rollers in the space inclosed' bythe sides of the receptacle, the-said boards and the rollers-forming a kind of bottom for.

the receptacle. In the drawings I have. representedthe space within the receptacle shortened to suit the size of the section or blank by the insertion of a vertical partition 97. Theisections; or blankswill be placedinto the division: of the receptacle which is at theleft-hand side-of the said vertical partition.- If desired, theboards- 10 my be set down far enough between the rollers-4 4 to leave portionsofe thesaid rollers exposed above the boards, 10, altl1ough this is not necessary.

5 The-rollers are embodied in the machine. merely to permit of the latter being used incutting. long boards into barrel-heads-,the receptacle and special form of pusher shown beingomitted-incase of such use. One side of thebox iscut away. at 93, to exposethe interiorof theibox and its contents. The pusher slides over the rollers and these bridging.- boards, and in its forward movement itsend carriesbefore it the bottom section of the pile 5 5 of sectionsor blanks in. the-receptacle, push in g disks, which at this time-are separated.

11; isa guide-apron at the delivery end of the; receptacle 9, serving to hold down the.

movingsection and. direct thesame properly between the clamping and cutting devices. The sections or blanks may be composedeach of one piece of material, or two or more narrow strips may be placed together side by side in the receptacle and fed forward asone by thepusher. the sections properly laterally and also for For the'purpose of guidingthe purpose of holding pressed together properly the two or more narrow strips, which in some cases will be placed side by side, I employ

lateral gages

12 and 13, one of which is placed at the rear of the clamping and cutting devices and the other at the front thereof.

- To facilitate the entranceof the sections between the

gages

12 and 13, I bevel off the inner corner of gage 13, as at 14, at the end of the said gage which is adjacent to the receptacle 9. The entrance of the sections or blanks is further facilitated by the fact that the gage 13 is made yielding and movable toward and from the gage 12. The said gage 13 is secured by screws 17 to blocks 16, passing through slots 18 in the topof the. tableD, the said blocks being secured by screws 15'in-posit-ion upon rods, 14, slidinglaterally through the sides of the table. D,-the said rods. 14 ati their ends being provided with pins,which play 'in slots in-arms 19, mounted uponithe rock-shaft 20, which rock-shaftis supportedin. bearings atone side of the table. An. inwardly-projecting arm121'on the said rock-shafthaseconnected therewith airod? 22, the; lower end of whichisprovided with a yoke 23,.the latter being slotted, so-that it may slide upon shaft 25, and being provided with astudor roller 24, intended to be struck byacam 25; on the-said shaftt in the revolution of the: said shaft.

Theweight. of arm- 21 and of therod 'and yoke suspendedtheref'rom holds the gage 1 3 pressed in a;yielding mannertoward'gage 12'.

ber, soas to grip: the, section. firmly edgewiseand in such manner that if the, section or blank, is composed of two or morenarrow' strips, each less in width than anentireseetion or. blank, suchstrips shall be; forced. closelytogether at their edges'before they'are engaged by the clamping devices. Iii-orderto'provide for variations; in. thewidth: of the; sections as; they-are fed forwardbetween the gages-12-and 13, I interpose: a. yielding con:- inection between the cam and the: movable gage 13.- I have shown hereintheupper-end of rod. 22 passing freely through: a hole in the inner end of arm 21 and a spring'26 connect? ed atvits upper end to.thearm 21 and atits -lower" end to. the-rod 22. adjusted alongthe, rods 14 when: itis desired to vary the'distance of thegage 13" from'th 1 gage 12. ing the said bottom section between the .clamp- I have hereinforconvenience;shown anarrangementof clamping and cuttingmechan ism which is the same as that. presented in: my application aforesaid. Any other mechanism; whereby thesections inay'beiproperl y 1 held in position and the disks maybe formed can be-employediinstead. Thedevices shown be apparent from the foregoing. A pileof Bythe action of cam 25 uponvstudr or; roller 24 the- Blocks- 16 maybesections or blanks of the width and length necessary for the production of the desired disk will be placed in the receptacle 9, these sections or blanks being either each of one piece of the full width necessary or of two or more strips together making up the Width. Each of the sections or blanks in turn, as it reaches the bottom of the pile in the receptacle, is engaged by the pusher and pushed forward under the apron 11 and between the gages l2 and 13, the gage 13 moving outwardly to permit the entrance of the section between it and the gage 12. The gage 13 is then pressed inwardly against the edge of the section through the action of cam 25, and then the clamping devices close upon it and itis acted upon by the cutting mechanism.

I claim as my invention- 1. The combination, with disk forming mechanism, of a receptacle for blanks, a pusher for moving said blanks successively forward to the said mechanism, means for operating the said pusher, and gages for the blanks disposed adjacent to the disk-forming mechanismand on opposite sides thereof and of the line of feed, the blanks lying between the said gages while the disks are being produced therefrom, substantially as described.

2. The combination, with disk forming mechanism, of a receptacle for blanks, a 30 pusher for moving said blanks successively forward to the said mechanism, means for operating the said pusher, and gages for the blanks disposed adjacent to the disk-forming mechanism and on opposite sides thereof and of the line of feed, the blanks lying between the said gages while the disks are being produced therefrom, one of said gages being pressed yieldingly toward the other, substantially as described.

3. The combination, with disk forming mechanism, of a receptacle for blanks, a pusher for moving said blanks successively forward to the said mechanism, means for operating the said pusher, gages for the blanks disposed adjacent to the disk-forming mechanism and on opposite sides thereof and of the line of feed,the blanks lying between the said gages while the disks are being produced therefrom, and devicesacting to move one of the said gages toward the other at intervals to compress the blanks edgewise, substantially as described.
