SPECIFICATION forming part of Letters Patent No. 329,007, dated Qctober 27,1885.

1 Application filed December 19, 1884. Serial No. 150,724. (No model.) I

1'0 all whom it may concern:

Be it known that I, HORACE S. BOYNTON, a citizen of the United States, residing at Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Tenoning-Machines;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention, to be hereinafter claimed, relates to improvements in sash and door tenoning machines, and-particularly to the mechanism for supporting, adjusting, and operating the cutter-heads, for supporting, holding, and carrying the material, and for cutting the tenons and clearing away the chips.

My invention, hereinafter described, may bereadily understood by reference to the acoompanying drawings, in Which- Figure 1 is a side elevation of a tenoningmachine embodying my improvements. Fig. 2 is an end view (left end) of same machine. Fig. 3 is a cross-section on line as x of Fig. 1, and having a part of the case inclosing the presser-feet broken away. Figs. 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13 are details.

The same parts are indicated by like reference numbers or letters in all the views.

1 is the supporting-frame. 2 is the drivingshaft, extending lengthwise of the frame,with hearings in the lower part of said frame and having proper connections withthe extrinsic power by which it is driven. Upon one end of the frame 1, and rigid thereto, is the small raised platform 3, and at the other end, and traveling thereon, is the movable platform or carriage 4, which platform and carriage each support frames carrying mechanism hereinafter described. This carriage 4 is made to travel on the frame 1 toward and from the rigid platform 3 by means of the mechanism shown in Figs. 1, 3, and 4. Beneath the carriage 4, lengthwise of and rigid at its end to the frame 1, is the screw-threaded rod 5, and traveling thereon the internally-screw-threaded mitered pinion 6, which pinion is provided on its rear with a flange having a groove in its periphery, in which groove thelower forked.

end of the hanger 7, rigid to the carriage 4, fits movably. The crank-rod 8, having its bearings in the carriage 4, is provided at its inner end with a mitered pinion meshing with the pinion 6,.and at its outer end with the crank'handle 9, by the turning of which the travel of the carriage 4 is effected through the mechanism just described.

On the platform 3 and carriage 4, respectively, is a circular plate or disk, 10, Fig. 10, having on its under side, around near its periphery, a flange or lip extending downwardly and outwardly, forming with the under side of the disk a groove adapted to receive and moveupon the ring 11, which ring is rigidly affixed to the upper surface of the platform 3 and carriage 4, respectively, and upon which ring 11 said disk is supported and rotates horizontally; The disk 10 is provided on its periphery with the lug or catch 12, adapted to impinge against the pin 13, which is rigid in and extends upwardly from the top of the platform or carriage, whereby the rotation of the disk 10 is checked, and against which it is held. The disk 10 is also provided with the rigid upturned lugs or flanges 14, toiwhich the upright frame 15, carrying the cutter-r heads and other mechanism, is affixed.

Supported by and having a vertical movement in grooved ways upon the face of the frame 15 is the upturned yoke 16, provided with journal-bearings adapted to receive and support the horizontal arbor 17 ,which carries the lower cutter-head, 18. This arbor 17 has rigid thereto abelt-driven pulley, 19, and carries the cutter-head on its front or projecting outer end. Above theyoke 16, and supported by and having a vertical movement in grooved.

end. The bracket 20 is supported by and is raised or lowered with reference to the yoke 16 by means of the screw-threaded rod 23,.

which passes vertically through and has a screw adjustment in the bracket 20, and rests at its lower end upon the top of the yoke 16. This rod at its upper extremity has a handwheel, 24, rigid thereto, by turning whichsaid bracket is raised or. lowered with reference to the yoke 16, as described, and said bracket may be clamped to the frame by turning the hand-wheel a.

' The yoke 16 and bracket 20 are bothraised and lowered concurrently by means of the screw-threaded rod 25, which passes vertically from below up into and has a screw adjustment in the yoke 16, and is supported by a rigid collar thereon, resting upon the disk 10, through which the rod passes, and below which it is provided with the rigid mitered pinion 26,which meshes with a mitered pinion or the horizontal rod 27, which rod 27 has its bearings in platform 3 or carriage 4, respect ively, and isprovided at its outer extremity withthe rigid hand-wheel 28, by the turning of which saidiyoke 16 and bracket 20 are raised or lowered concurrently, as described, and the. yoke16 may be clamped to the frame 15 by turningihc hand-wheel 12. Above the bracket 20 is. the. belt carrying and tightening idlepulley 29. This pulley has .the bearings of its journalsin the outer ends of two arms, 30, pivoted at their inner ends in a nearly horizontal position to the top of the frame 15. These arms 30 are each providediwith a segmentalarm, 31', rigid theretoin front of the pivotal point of said arms and extending downwardly and'to'rearward of the pivotal point of saidarms, and at their respective rear ends have attachedthereto acord or strap, which strap at its other extremity is attached to and windsovertothe front on a shaft havingits bearings in-t-he brackets 20, and which on its. outer end has rigid thereto the pulleys 32, over and upon which runs acordattached thereto. at one end, and supporting at its other end the weight 33,which weight, by its gravity,.rotates the pulley 32 and winds up the strap, there-';

by pulling down on the rear end of the seg-.. mentalarm andthrowing up the front endof the arms 30,.tightening the belt runningover; the pulley 29, carried thereon. The belt-pul-- leys on arbors17 and 21 and the pulley 29 are, when the disk 10 it swung around placing the cutter-head in position for work, located vertically above a driving-pulley, 34, on the driving-shaft 2, and over and upon all these runs the driving-belt35. A revolving coping-tool, 36, is fixed on the lower end of a vertical ar.- her having its bearings in boxesrigid to the bracket 20, and is driven by a belt over the pulley' 37'on the arbor that carriesthe tool. A similar reversed coping-tool, 38, upon a vertical arbor, having its bearings in boxes. upon the-yoke l6,is driven by a-belt over the. pulley-39 on said. arbor. These coping-tools cut the coping-recesswithin the shoulder on. the stuff atthe inner end of the tenon, doingtheir. work just after the cutter-heads have formed'the tenons.

40 are segmental arms, respectively pivoted at their. inner ends upon an arm or rod affixedv to bracket 20, and extending outwardlythere+ fromparallel with the arbor carrying the cut:

ten-head, which arms at their outer extremities carry a chip-breaker, 41, Figs. 1 and 3, extending from one arm to theother and rigid thereto, and so constructed as when thrown down upon the stuff in the rear of the cutterheadto catch and remove the chips, and when not'in use to be thrown back away from the cutter-head.

Upon the yoke 16, in the rear of the lower cutter head, and directly beneath the upper cutter-head, is the vertically-adj ustable brackand isadapted to bear upon the upper surface of the tenon and steadyit while the upper cutter and the coping-toolsare doing their.

work. The stuff is supported and'fed to the cutters upon a carriage consisting of thetwo endless sectional racks 45, running. over the idle-wheels 46, and supported on aframe and driven. by mechanism hereinafter to'be described.- The endless racks .are constructed in links or sections pivoted together, asshown in Fig. 7, eachsection having on its under.

side lateralcogs so-formed that when-the sections are pivotedtogetherthey form a.con-.

tinuous' rack, which runs upon and is driven by the pinion 47 on driving-shaft 48.. Rigid on the outer surface of the endless racks ,45, at equal=and convenient distances are the ,lugs .49, adapted to catch: the stuff" placed on the carriage and force it forward .on the car.-..

riage.- These endless racks are each supported upon a frame, 50, extending longitudinally across the machine and in the line of movementof the stuff to be operateduponh These.

frames 50 are supported ,by legs 51 and. 52, which on side 51 are rigid topthe platform 3 and carriage 4, respectively, andon theother side, 52, rest upon the frame 1.- These frames 50 have each two parallel walls connected to-..

gether by across bottom wall,.as shown in ;cross-'seotion in Fig. 8. The idle-wheels 46- have bearings and are supported in the re- ;spective ends of the frames 50. These frames 50-have each-a sliding-extension end, 53, having one or-more slots, through which pass the lscrew-threaded bolts 54, which bolts fit and turn incorresponding screw-threadsin the;

imainrpart of the frame 50, and by which slots jandibolts' said extension end. ofpsaid frame.

may be adjustedvoutor. in, and are adaptedto itightening the endless racks 45.- The top of ;these frames 50 are each provided with a Ion-J gitudinal.groove,j(shown in section in Fig.8,}f

in. which said endlessrack 45 runs and is supported. The pinions47 each have rim-55,.

having peripheral cogs, which rim is adj ust ably affixed to an encompassed sleeve, 56, by

- rack in one or all of these pinions, whereby the endless racks are made to run evenly and truly with relation to each other, andthereby carry the stuff squarely up to the cutters.

, This adjustment is accomplished by means of the set-screw bolt 58, provided with a cam, 59. (Shown in Figs. and 9.) This bolt 58 passes through an aperture in the flange of sleeve 56 and screws into the flange of the rim 55.

' 1 On that part of the bolt within the aperture in the sleeve is the cam 59, sol'that by turning this bolt slightly the sleeve is rotated slightly forward or backward with reference to the rim 55, and is held in position by the set-screw bolts 57. The sleeves 56 encompass and fit upon the shaft 48, and are adjusted thereto at the carriage (4) end of the shaft by an inwardly-extending feather, 60, which projects therefrom into a groove extending longitudinally on said shaft, whereby said sleeve is caused to rotate'with said shaft, but has a free longitudinal sliding movement thereon, and at the other end of the shaft the sleeve is. made ri gid-to' said shaft by a key inserted in said groove in the shaft and in acorresponding groovein the sleeve. The pinions47 are each supported on the frames 50 by a circular flange or ring, 61, which ring isprovided with a wingfloy and through which said ring is affixed rigidly to the frame 50, and said ring fits into a groove in the face of the pinion, as shown in Figs. 6, 8, and 9, and on this circular flange or ring said pinion rotates. The shaft 48 is driven by the eog-wheel 62, rigid upon the end thereof, which meshes with a pinion on the shaft 63, which shaft 63 is in turn driven bythe belt-wheel 64, rigid thereon, and over and upon which wheel runs a,

belt, which also runs upon and is carried by a small wheel onshaft 65, which shaft is driven by the friction-wheel 66, rigid thereon, bearing against a small friction-wheel, 67, on the driving-shaft 2.

The shaft 65 hasiits bearings in a sleeve, 68, Fig. l, which sleeve is supported at its inner end in a ring pivoted to the frame 1, and at its outer end in a lever, 69, Fig. 2, which lever is pivoted at its inner end onto the frame 1, and at itsouter end is preferably provided with the weight 70, which'by its gravity carries the shaft 65 down, so that the wheel 66' is theset-screw 77.

contact with wheel 67, releasing the feeding mechanism from the driving'shaft and stopping the feed. i I

f Vertical shafts 74,-having their hearings in brackets made fast in and supported by the platform 3 and carriage 4, respectively, are

driven by the belt 75, passing over a fast pul ley on the bottom of said shaft and over a pulley fast on the driving-shaft 2, which belt' is tightened by the adjustable idle-wheel 76, Y

having its bearings adjustable up or down by Upon the shafts 74 arethe fast 'pulleys78 and 79, upon which belts are carried, that also run upon the pulleys 37 and 39, respectively, and drive the shafts carrying the upper and lower coping-tools,- 36 and 38.

The upright brackets or standards 80 at their lower extremities are rigid to and supported upon the platform 3 and carriage 4, respectively. Rigid to the two of thcss standards 80, that are at the front side of the machine, are horizontal brackets supporting guards 81 and 82. The guard 81, on the left-hand side,

is adjustable on its bracket toward and from the carriage by means of the slots in the bracket and legs onthe guard passing through said slots and secured by the set-screws83 thereon. The guard on the right side of the machine is shown in detail in Figs. 11

and 12. This guard, for convenience, preferably extended somewhat higher than the guard on the left side has an inward inclination downwardly, so that stuff as it is delivered to the machine may be readily placed between the guard on the left and this. one, and as it comes to rest at the bottom of the guard and upon the carriage, the stuff will be caused to take its proper position firmly against the guard at the left of the machine,

from which place it isto be carried forward in the same position by the endless racks to the cutter-heads." This guard 82 is mounted upon a bottom, 84, having a sliding movement toward and from the carriage, being provided with one or more securing lugs or bolts, 85,

being supported by and having a horizontal movement in a lug affixed to saidbr'acket, and

around whichrod is a spiral spring,88, adapted to hold said guard against the stud, but sufficiently yielding to accommodate between the guards from time .to time pie'ces'of slightly varying length. These guards have their bottom on a level with the top of the carriage. These standards 80,in pairsfon the platform 3 and carriage 4, respectively, support on their ICO upper extremities presser-feet 89 in sets, one i set supported by each pair of standards. The case 90,inclosing these presser-feet, consists ofa longitudinal box or frame attached to the upper ends of the standards 80, above and parallel with the carriage. The presserfeet,

in sets or series,having their soles slightly below the'case 90, are provided with upwardlyextending shanks having their hearings in and supported by said case and having avertical movement therein.

- Within said case, around said shanks, are

' spiral springs 91, resting at their upper ends screw-threaded bolt, which passes through aagainst said case and at their lower ends against a pin or lug in said shanks, whereby said feet are given a downward pressure limited by the supporting-pins through the tops of the shanks above the upper bearings. The case90 is attached to the standards 80 by'a vertical slot, 92,'in the standards into said case, and said case is adjustable vertically by means of the screw-threaded rod '93,supported, near its upper end,by a shoulder resting upon a shoulder of the standards and passing downwardly throughsaid shoulder on said standards, into said case 90, in which case said rod turns upon a screw thread thereon and a corresponding screw thread within said case, whereby said case may be raised or lowered, and may be fixed in position by the set-screw passing through the slot 92.

. The'rods 98 are provided with rigid mitered pinions at their upper extremities, which mesh with pinions 94 on the horizontal rod 95, which ,rod has its hearings in the top of the standards 80,and can be rotated by the handwheel 96, rigid thereto, thereby raising or lowering the case inclosing the presser-feet.

1 The cutter-heads 18 and 22 carry the knives that cut the tenion on the stuff, These cutter-heads are provided with scroll-like surfaces, on which the knives are aff xed, and

- this peculiar form of surface I do not claim in this application, but reserve the same for a separate patent to be hereafter applied for by me according to law. I

f'lhe shaft 48, beside the supporting-sleeve 54 and flange 61, hereinbefore described, is also supported and has bearingsat its respective ends in the standards 97,- rigid upon frame 1.

It will be seen that the carriage 4, and the machinery thereon supported, may be readily moved toward or from that end of the machine on which the platform 3 is by rotating the crank 9' through the devices 5 and .6, 7 and 8 therewith. When this carriage is so moved, it .also carries with it the belt- pulleys 98 and 99 on the driving-shaft 2 by the hanger 100, rigid to said carriage, beneath and at its lower forked extremity, riding within and bearing against the sides of a groove within a sleeve, which sleeve is rigid to and connects said pulleys 98 and 99 and surrounds the shaft 2. 101 is a tight pulley on shaft 2, by which power. is applied thereto through a belt to drive the mechanism, and 102 is a loose pulley on said shaft, upon which said belt may be thrown to release the shaft 2 from the driving-power.

, In Fig. 1 the dotted lines indicate a piece of stuff (doorrail) on the carriage being car- 'ried' forward against the cuttingtools, which on the left are shown inpositiondoing theirwork. On the right the disk 10 is thrown -around,-placing the cutter heads and other devices thereon outside, away from'their work and in a position in which they canbe readilyrepaired or the knives-sharpened.

I do not deem it necessary to further de! scribe the operation of this machine, as its time, and I can readily adjust these duplicate of tools at such distance from each other as to cut stuff of greatly varying length.

What I claim as new, and desire to'secure by Letters Patent, is
