To all whom,l it puny concern.-

`Be it known that I, CHARLES E. SAND- STRQM, residing at Chicagoin1 th'eccunty of Cook'and State ofIllinois, have invented certain new and useful Improvements in Saw` ing, Jointing, and Boring Machines, of which the following is a specification.

My present invention'relat'es to one of the several machines which I may useto carry out my new and improved process of making elliptical picture-frames. The function of the present machine is toV produce several quadrilaterals, usually in the shape of trapezoids,which are of a certain definite shape and which may have their ends cut with certain grooves to form what I may call a v. hooked rabbetLjOint and-'have two or more holes bored into one of theV surfaces to secure exact registration of the partsin all subsequent operations-to which they are subjected.-

It willbe seen that the machine has three principal functions, first; to cut the trapezoids, ordinarily froma board of the width of the pieces; second,to cut the peculiar grooves inthe ends of thepieces if .said grooves are used, which grooves .when united form the hooked rabbeted joint, and, third, to bore the holes in one ofthe surfaces ofeach piece.

Incarrying out my invention to cut the trapezoids,'two sides ofwhich are not parallel,itl becomes'necessary tohold the material and advance the saws upon the material in the line' of. the cnt to bemade. As the holes to be bored in the trapezoids must occupy a certain definite relation relative tothe sides thereof, it becomes necessary to -bore 'the holes in the stationary material, preferably at the time thesaw's are cutting it oi, so that by no possibility of disarrangement between the time the material is cut off and the holes boredcan-the holesv be misplaced. As the twocutting-off sawsv act'during the same' op'- f eration, it also-becomes 'necessaryto cause one saw to act atleast slightly'in advance of the A,otherv in" order vthat the :outermost saw (from the direction the material is being fed to the machine) shall have completedcutting off its end before the other ysaw has severed the trapezoid Ifrom the strip `from which it is being cut.- j

Fig. 13 is a plan view of said support. Fig. 14 shows an inverted plan viewand side elevation of the rough frame formed by joining together the trapezoids formed by this machine. Fig. 15 is a sectional view through the upper saws and the board on an enlarged scale, showing how the grooves are formed and the ends cut off by the same operation. Fig. 16 is a similar view of the lower saws. Fig. 17 is a plan view of the metallic portions of the guide-table. Fig. 18 is'a plan view of the longitudinallyad- Vjustable plate upon which the guide-table is adjusted, a dierent position of said table fromthat'of `Fig.` 17 being indicated by the Fig. 19 is a sectional view through the adjustable guide-table and the drill-supportsonthe line 19 19 of Fig. 17, andlFig. 20 isa rear elevation of the parts shown irl-Fig. 19.

Referring, first, to Figs. 3,14, and 15, it will be seen that each of the trapezoids A has its ends formed by the action of the saws C in cutting entirely through the board, while the saws D cut of a portion of the surface adjacentto the end, thus forming the surface E parallel to the main surfaces. The saws F cut stilldeeper than the saws D, but do not cut IOO entirely through the board, so that they form the groove G. In all the ends of the trapezoids A it will be seen that the surface E enters into the groove G of the adjacent piece, thus forming a hooked or locked rabbeted joint. The two drill-holes II, formed in each piece are bored simultaneously by the action of the drills J. (Best shown in Figs. 5, 17, and 19.) Of course I do not limit myself to the employment of two drill-holes in each trapezoid, as one or more may be employed.

Referring now especially to Figs. l and 4, it will be seen that the general form of the machine, as seen in plan view, is segmental, the upper part of the frame consisting of the two bearing-segments K and L, each of which has the plain surface M, in the outer edge of which is the segmental slot N, which has the bolt or stud O as its center. Mounted upon vthese segments are the adjustable guideplates P and Q, supporting the upper and lower sets of saws, respectively. The details of these plates are illustrated in Figs. 8, 9, and 11, where it will be seen that they are provided with the leaves R and S, which are of the ordinary rule-joint construction and are mounted on the stud or bolt O, so that these plates swing about it as a center. These plates are provided with the bolts T, which pass through the slot N and by which they are secured in any desired position. To enable these to be readily adjusted at any one of certain angles which are frequently used, I may make a hole U in each of these plates and through this hole pass a pin V, which passes into one of the series of holes IV;

formed in the surface M, depending upon the angle to which it is desired to adjust the saws. As will be seen from Fig. 5, the sides of these plates P and Q are formed with the ribs X, to which are bolted the overlapping strips Y, thus forming the grooves Z on the inner edge of each side of the plates. For lightness these plates may have their centers cut away, as clearly shown in the drawings, and to accommodate the saw-driving belts. In the ways formed by the grooves Z are the plates A', which form the basis of the sliding supports for the bearings of the saws. These plates A have the ribs or flanges B' on their edges,which take into the grooves Z and form the sliding bearing-surfaces. The rectangular base-plate A' has formed at its rear end the vertical plate C', which has the flange D' (best shown in Fig. S) on its front sides, having formed therein the groove E', into which take the flanges F', which are formed on the sides of the journal-box plate G'. This journal-box plate G' is of a somewhat peculiar shape and consists of the central part H', the sides of which have the flanges F', previously mentioned, and the rear end of which has the rearwardly-projectinglug J', passing through the aperture K', formed in the plate C'. A screw or bolt L', passing through the lng M', integral with or fastened to the upper end of the plate O', and cooperating with the screw-threaded aperture in the lug J', serves to adjust the journal-boxes at any height that may be desired. The central plate II' has rigidly fastened to or formed integral therewith the lower halves N' of thejournal-boxes, and these are strengthened by the brackets or webs O'. As an additional support or adjustment for the lower halves of the journal-boxes, I form the slots P' in the plate C', through which pass lthe bolts Q', which are secured to the brackets O' and by which they may be clamped to the plate C'. The upper halves R' of the journal-boxes are similarly secured by the bolts S', passing through the slots T', formed in the plate C'. rPhe journal-boxes carry the shaft U', upon which is fastened the belt pulley or roller V', the belt therefor passing up through the aperture W', formed in the plate A'. The inner end of this shaft carries the saws C, D, and F, which, as will be readily seen from Fig. 15, are of different diameters and widths, C being an ordinary thin circular saw of sutieient diameter to cut through the stuff, whereas D and F are very much thicker and of sufficient diameter to cut out the surface E and the groove G.

As will be best seen from Figs. 5 and 6, the set of saws upon the segment K operates upon the upper side of the board, while the set on the segment L operates on the lower side, the mountings of the lower set being similar to those of the upper set, the differences being only such as are necessitated by the different heights of the bearings. As will be readily seen, it is impossible to channel and cut off both ends of the board at once by moving the board onto the saw, so that it is necessary to move the saws in relation to the board. To provide for this movement, links X' are pivotally mounted at one end between the lugs Y', formed on the rear of the plate C', while the other longitudinally-slotted ends are adjustably connected by the bolts Z to the links A2, which may also be longitudinally slotted and which are pivotally mounted to the cross-piece B2. This cross-piece B2 has the lug C2, to which is pivotally mounted the arm or lever D2. (Best shown in Fig. (i.) This lever D2 is mounted by the longitudinal slot E2 upon the shaft F2, to be subsequently described, and has its lower end enlarged and formed with the elongated segmental slot G2. The upper edge of this slot is provided with a series of gear-teeth H2, while the loweredge is similarly provided with gearteeth J2. Through this slot G2 passes the shaft K2, which is continuously rotating during the operation of the machine and which has fastened thereon the gear-pinion L2. Beneath the curved lower end of this lever D2 is a treadle-lever M2, pivotally mounted at N2 at the bottom of the machine and having its forward end O2 projecting outward in position to be easily reached by the foot of the operator, who stands in front of `the machine. The operation of these devicesis as follows: When the material ICO is in position to be sawed, the parts are in the position shown in Fig. 6 and the operator depresses the front end O2 of the treadle. The rear end is raised, and it raises the lever D2, the elongated bearing E2 permitting this movement until the gear-pinion L2 is in mesh with the teeth J2. The movement of the pinion carries the lever D2 in the direction of the arrow, and by the link connections of the supports for the saws they are at the same time slid forward in their bearings, thus operating upon the material. Of course the saws are run continually by means of the belts coperating with the belt-pulleys V. Vhen the cutis made, the operator releases the treadle, and this permits the lever D2 to descend, and when it has reached its lower position the teeth H2 are in a position to engage the pinion L2, so that the lever D2 and the saws are carried back to their normal position, when the board can be advanced ready for another operation.

From an inspection of Figs. 1 and 4 it will be apparent that the saws on the right-hand arbor are set in advance of those on the lefthand arbor, so that the saws on the right-hand arbor will have completed their work before the cutting-off saw on the left-hand arbor severs the integral piece upon which both sets of saws are working from the main piece of material. This arrangement of the saws is essential; otherwise the quadrilateral being severed from the strip before or at the same time the other end was finished would prevent said other end from being properly iinished.

While the saws are cutting and channeling the trapezoids the drills J are raised to make the holes H. The mechanism for this action is best shown in Figs. 4 to 7 and 19 and 20. A generally U-shaped piece P2 has its bottom part elongated, so as to form a plate Q2, which is bolted to the cross-piece R2, forming a part ofthe framework. The sides of the frame P2 are much narrower than the bottom and have the triangular portion S2, connecting the narrower portion with the plate Q2, constituting the elongated bottom portion and operating substantially as a bracket. This triangular portion forms a shoulder at T2, which shoulder rests upon the horizontal portion of the angle-shaped cross-piece R2, previously mentioned. Asimilar U-shaped frame U2 is secured to the narrow sides of the primary U-shaped frame P2 to strengthen it without interfering with the mechanism mounted therein. The sides of this frame P2 have the inwardly-projecting flanges V2 formed on theirupper sides, and these flanges V2 coperate with the shoulders W2, formed b v cutting away a portion of the upper edges of the plate X2.` (Shown detached in Fig. 18.) This plate X2 has a downwardly-projecting lug Y2, through which the screw-threaded bolt Z2 passes. This screw-threaded bolt Z2 is rotatably mounted in the U-shaped frame P2, so that the position of the plate X2 may be adjusted tothe front or the rear of themachine, as may be desired. This plate X2 has mounted thereon a plate A3. (Best shown in plan view in Fig. 4.) This plate is pivotally mounted upon the plate X2 by means of the bolt B3, while the bolt C3, passing through the segmental slot D3 in the plate A3, enables this plate to be secured at any desired angle relative to the plate X2. As this adjustment is ordinarily in one of two or three positions, I provide for positioning these plates rapidly by means of the round hole E3 in the plate A3 and the three similar holes F3 in the p late X2. A pin G3 is arranged to be put through a hole in the guide-table and through the hole E3 and into whichever of the holes F3 it may be necessary to secure the required adj ustment. The plate A3 has projecting downwardly from its rear end a leg H3, which has lugs J3 formed on either side thereof and projecting forwardly therefrom to form one side of the bearing-boxes K3 for the shafts L3 of the drills J. The lower part of the leg H3 is formed with the lugs M3, similar to J3, but narrower and forming parts of and supports for the bearing-boxes N3 for the lower ends of the drill-shafts L3. These shafts have fastened thereto the belt-pulleys O3 between the journal-boxes K3 and N3. The foot of the leg H3 has forward and rear projections P3 and Q3, as seen in Fig. 19, and the elongated portion formed by these projections is bored through to furnish'a bearing for the L-shaped rod R3, the upturned L portion of which serves as a bearing for the idle belt-pulley S3. The side plates T3, projecting downward from and secured to the ends of the projections M3, form bearings for the eccentric-roller U3, pivotally mounted therein and furnishing a support for the lower ends of the shafts L3 of the drills J. Referring now to Fig. 6, it will be seen that this eccentric-shaft U3 has fastened to its outer end a crank-arm V3, which is pivotally connected by the link W3 to the arm D2. The shaft F2, previously mentioned, has rigidly secured thereto the belt-wheel X3, by

which it is driven by means of the customary belt Y3. This shaft has fast thereon the gearpinion Z3, which meshes with the gear-wheel A4, fast on the shaft K2, previously mentioned,

'so it will be seen that the rotation of the shaft F2 drives the shaft K2 and serves to reciprocate the sliding bearings of the saws. Also m ounted on the shaft F2 are the loose belt-pulleys B4'. A belt-wheel C4, to which power is applied, hasa belt D4 passing upward over the idle pulleys B4, around the driving-belt pulleys O3, and around the idle beltpulley S3, as shown in Fig. 7. By means of the bolt or setscrew E4 the idle pulley S3 can be adjusted to any position desired to give the desired tension to the belt D4. The operation of these devices is as follows: It will be seen that through the connections of the drills with the bolt-pulleys C3, to which power is applied, these drills will be running continuously, and whenever the treadle is depressed, thereby IOO IIO

rocking the lever D2 forward, the link VVaud the crank-arm V3 will rock the eccentric-shaft U3, at the same time raising the drill-shafts the required distance so that they will penetrate into the material and form the holes I-I of the desired depth.

The guide-table previously referred to is shown in Figs. 1, 5, G, and 17 to 20. It consists primarily of the long plate F4, having the upwardly-turned flange G4 at its rear. This table terminates at its left-hand endpin a position to just permit the upper saws to clear it, while a slot H4 is formed in it to permit the lower saws to cut the material supported thereby. At the point in the flange G4 where the slot H4 occurs the flange is formed with a projection J4 thereon, which forms sufficient material so that some of it maybe cut away to form the vertical portion K4 of the slot H4 without materially weakening the table. The front end of the forward portion lof the table is formed with the upwardly-projecting flange L4 and the downwardly-projecting flange M4. This table is secured in position upon the plate A3 by means of the screws N4, and it also has the apertures O4, through which the drill-points project. Vhen the machine is ready to be put into operation, a filling-piece of wood P4,which is of the shape shown in Fig. 2, is secured upon the trapezoidal portion of the plate F4,which is formed by the slot H4. This filling-block is of suiiicient thickness to make this portion fiush with the rest of the plate F4, which is slightly higher. In addition to the filling-block P4 the vertical block Q4 is used, and this block is of a thickness depending upon the size of the work to be operated on and the distance it is desired to place the holes H from the edge thereof.

To securely hold the material in position while it is being cut by the saws, I fasten or form upon the raised portion J4 a bearingstud R4, upon which is pivotally mounted the hand-lever S4, (best shown in Fig. 6,) which has fastened on the under side thereof a block T4,which isin position to clamp firmly the material being operated on when the lever is depressed.

The operation of the machine will be readily apparent from the foregoing description and also the possibility of adjusting it to make any necessary or desired variations in the form of the trapezoidal blocks to be cut out.

While I have shown my invention as embodied in the form which I at present deem best adapted for the purpose in hand, it will be understood that I do not desire to be limited to the exact form shown and described, but only so much as may be necessitated by the state of the art.

In a woodworking-machine, the combination of a plurality of cutting-off saws, a separate support for each saw, a corresponding number ot ways, in which the supports may be reciprocated to advance the saw upon the work, means for rotating said saws, a work-supporting table located at one side of said ways, means for adjusting the position of said table relative to said ways to vary the angle at which the saws are presented to the work, and means for reciprocating said supports so that the out of the saw farthest from the table shall be completed first.

22. In a woodworking-machine, the combination of a plurality of cutting-olf saws, separate supports for each saw, a Corresponding number of ways adjustable to vary the angles between the saws, means for rotating said saws, a work-supporting table located at one side of said ways, means for adjusting the position of said table relative to the ways to vary the angle at which the saws shall be presented to the work, and means for reciprocating said supports so that the cut of the saw farthest from the table shall be completed first.

23. In a woodworking-machine, the combination of a plurality of cutting-olf saws, separate supports foreach saw, a corresponding number of ways adjustable to vary the angles between the saws, means for rotating said saws, a work-supporting table located at.

one side of said ways, means for adjusting the position of said table relative to the ways to vary the angle at which the saws shall be presented to the work, means for reciprocating said supports so that the cut of the saw farthest from the table shall he completed iirst, and a clamping-bar for holding the material upon said table.
