JOHN B. OHAOE, OF ORANGE, MASSACHUSETTS.
WOODWORKING MACHINERY.
SPECIFICATION forming part of Letters Patent No. 603,037, dated April 26, 1898.
'Serial No. 578,303. (Nomodel-l To all whom it may concern.-
Be it known that I, J OHN Bovnnn OHAon, of Orange, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in WVoodworking Machinery; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.
This invention has reference to improvements in woodworking-machines, and especially in machines for cutting concave depressions in boards to serve as thumb-holes.
The object of the invention is to increase the accuracy of machines of this character and to render the same automatic in action.
The invention consists in the peculiar features of construction and combination of parts, as may hereinafter be described, and pointed out in the claims, whereby the object of the invention is accomplished.
Figure 1 represents a side elevation of the improved thumb-hole-cutting machine. Fig. 2 represents a plan view thereof. Fig. 3 represents a vertical longitudinal sectional view of the same. Fig. 4 represents a cross-sectional view. Fig. 5 represents an enlarged view of details of the cutter and the device for lifting and depressing the same. Fig. 6 represents a board illustrating the style of thumb-hole out by this machine.
Similar numbers and letters of reference designate corresponding parts throughout.
The mechanism is supported on a framework consisting of the standards, as 8 and 9, the longitudinal brace 10, connecting the pairs of standards, and the base or top 11, mounted on the standard. Extending through a portion of the length of this top 11 is the slot 12, in which the feed-block 13 is reciprocal, the limit of the forward movement of this block being regulated by the set-screw 14, working through the depending portion 15 of the top 11.
On the top 11 is a hopper formed by the partitions or ends 16 and 17. The end 16 is stationary, having the lower feed-opening 18, governed at the center by the vertical adj ustable bolt 19 and the webs 20 and 21. From the web 21 and the adjoining portion of the end 16 extends the bearing-support 22. The end 17 is adjustable on the top 11 and is supplied with a clamping device 23, traveling in the groove 24 of the top. On the inner surface of this end are adj ustably mounted the guides 25 25.
In the lower portions of the webs 20 and 21 is journaled the shaft 26, having the handle 27 and the oppositely-extending screw- threads 28 and 29, and on these threads are engaged the threaded sleeves 30 and 31, which are secured to the guide- arms 32 and 33, the vertical members 34 and 35 of these arms extending upward on the inner surface of the end 16. To these arms 32 and 33 are secured the downwardly-actin g presser- sprin gs 36 and 37. By the rotation of the shaft 26 the guide- arms 32 and 33, with their vertical members, are adjusted laterally to accommodate the particular width of boards which it is desired to operate on.
The shaft 38 is journaled in the bearing of the support 22. On the outer end of this shaft 38 is the belt-pulley 39, having the slot 40 formed in a portion thereof. In this slot is adjustably secured the clamp 41, havinga pivot on which the upper end of the connecting-rod 42 is journaled. The lower end of this rod is pivoted to the arm 43, extending from the shaft 44, journaled in bearings projecting from the standards 8 8. From the central portion of this shaft 44 extends the lever-arm 45, the upper end of which is connected with the feed-block 13 by the rod 46, pivoted at both ends.
The pulley 39 is driven by the belt 47, connecting the same with a pulley on the driveshaft 48, which is journaled in hearings in the lower portion of the frame and also carries the band-wheel 49. At the lower portion of the machine is pivoted the lever 50, having the member 51, carrying the roller-bearing 52, by the pressure of which against the belt 47 the slack in the same is taken up. When set to exert a desired tension on the I belt, the lever 50 is held by the pawl 53 en- 56. In this frame is journaled the cuttershaft 57, having the. band-pulley 58 at one end and the rotary cutter 59 and saw at the other end. The free end of 'thisframe has the slotted member 61, in which the pivot-block 62 is adjustable by means of the set-screws.
63. On this pivot is journaled the lower end of the link 64, the upper end of which is pivoted on the pin 65, set in the enlarged end of The suitable distance from the end 16 to accom-. modate the length of the boards AA; The guides 25 25 on the end 17 are next adj usted,
to thewidth of the boards. The'handle 27 is now turned to rotate the shaft 26 to draw together orseparate the guide- arms 32 and 33, the'members 34 and 35 being at the same time adjusted within the hopper. The boards 'A A'are'now placed in the hopper between the members 34 and'35 at one end and between the guides 25 25 at the other end, and the bolt 19'is adjusted to allow for the passage of but one board at a time through the opening 18. The mechanism is now started andthrough the driving-gear the pulley 39 and the shaft 38 is rotated; This causes the reciprocation of the feed-block 13,through the connections therewith. Passing through the opening in the lower portion of the end 17 the block engages the lowest of the pile of boards and carries it along through the opening in the end 16 and between the guide- arms 32 and 33, where it is engaged and pressed downward by the spring- plates 36 and 37. This forward movement of the board continues until the block 13 is arrested by the stopsorew 14. During this operation the cuttershafthas been rotated by its drive-band 69 but the cutter has been sufficiently raised to allow for the passage of the board. I/Vhen the forward movement of the board ceases, the shaft 38 has been sufficiently rotated to bring the pin past the vertical center. As this pin moves downward in its circular path the free end of the cutter-frame is also moved downward until the cutter 59 and saw 60 act to cut the thumb-hole B in the board A, the cutter forming the inclined concave recess,while the saw cuts the vertical wall forming the end of the hole. When this is accomplished, the cutter is raised by the rotation of the shaft 38 and the board is pushed out of the way by the next board which has been engaged by the feed-block after its return to its original position. Should the block 13 reach the stop 14 before the rotation of the pulley 39 has carried the clamp 41 to its farthest forward point of circular movement, this pulley will be held from rotation by the stop, the block, and the connections between the block and the pulley, the tension on the belt 47 being regulated to allow for the slipping of the belt on the pulley. A spring-finger 16" is seenred to the stationary end 16, extending o'utwardlytherefrom, and has a bearing on the end of the board next to the thumb-hole cutter, thereby firmly holding the board to the bed of the ma-' chine during the cutting of the thumb-hole, as clearly shown in Fig. 3.
Should it be desirable to out two thumbholes in the board, one of the guide-arms 32 33 is adjusted on its sleeve 30 or 31, so that the board in passing under the thumb-hole cutter will be off thecenter and the thumbhole will be cut to one side of the center. 7 To 7 cut the hole on the opposite side, the guidearm first adjusted will be replaced to its central position on the sleeve and theoth'er guide- 7 arm will be adjusted so as to bring the thumbhole cutter to that side of the center andthe boards will be again passed through the machine, when the finished board will then have two thumb-holes, one to either side of the r r r center.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a thumb-holemachine, the combination with the frame 56 pivotally mounted in the brackets 55 and 55, the cuttershaft journaled longitudinally in the frame, and the cutters on the free end of the shaft, of the feeding device and connections intermediate the same and the frame 56, whereby the cutter-frame is raised at the operation of the feeding device.
2. The combination with the screw-threaded shaft 29,,and the guide- arms 32 and 33 having bearings engaged with the screw-shaft and provided with the vertical ways 34 and 35 and the tension- springs 36 and 37, of the vibratory cutting device, as described.
3. In a thumb-hole machine, the combination with the cutter-shaft frame pivotally mounted and operated by the pulley 39 through the link 64, the cutter-shaft journaled longitudinally in the frame, a pulley on one end of said cutter-shaft and the cutter on the opposite end thereof, of the drivingpulley, the shaft on which the driving-pulley is mounted, the guide-pulleys, a belt working over the driving-pulley, the guide-pulleys and the pulley 58, and a belt working over the pulley 39 from the drive-shaft, substantially as and for the purpose herein shown and described.
4. In a thumb-hole machine, the combination of the following instrumentalities: the hopper provided with adjustable guides, the guide-arms provided with vertical members and presser-sprin gs, the spring-finger 16', the
