SPECIFICATION forming part of Letters Patent No. 616,353, dated December 20, 1898.
Application filed January 20, 1896. Serial No. 576,116x (No model.)
To all wwnt it 71mm/ concern:
Be it known that I, FRANCIS Y. PHILLIPS, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Cutting IVindow-Stile Pockets; and I do hereby declare that the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letro ters of reference marked thereon, which form a part of this specification.
This invention relates to machines for cutting window-stile pockets of the general character set forth in Letters Patent No. 483,968,
granted October 4, 1892. Generally and briefly described, said pocket is formed by side cuts (one or two) parallel with the edge of the stile, which sever the pocket laterally from the body of the stile, two offset end 2o cuts at each end of the pocket extending inward to a plane Within the stile between its broad surfaces and fractures with the grain of the wood connecting the inner extremities of the offset end cuts at each end of the z5 pocket. The end cuts made from the front surface of the stile are farther apart than those made from the back side, so that the pocketpiece is removable outwardly when the frame is in place in the building. I have heretofore 5o invented and constructed a machine for cutting this kind of window-pocket, the same being set forth in Patent No. 548,454, dated Octoher 22, 1895, and granted upon myappilcation, Serial No. 445,959, iiled September 15,
1892. I have also embodied the said invention in another and improved form, as set forth in a second application, Serial No.
536,611, filed January 24, 1895. The machine herein described is still another embodiment of the original invention, containing improvements and additional inventions.
The improvements herein described (using the term improvements to embrace additions) have for their objects, first, a construction in which a circular saw or a pair of circular saws may be employed for making the side orlengthwise cut or cuts; second, the separation of the operation of making the end cuts from that of making the side cut or cuts,where 5o by a machine may be adapted for making the end cuts alone and the side cut or cuts may be previously or subsequently made by another machine and whereby the machine when organized, as here shown, to perform both operations one after the other the convertibility of the machine to one adapted for either the end cutting of pockets and the like or the uses of a general sawing-machine may be more readily eifected, and, third, the convertibility of the machine into a table sawing-ma- 6o chine suitable for cutting dados, cross-gains, plowing, grow-dug, or plain sawing, and, fourth, a simpler and better construction of devices for actuating the cross-cutters.
Other improvements will also appear from the following description of the machine and will be pointed out in the accompanying claims.
In the machines illustrated in my said prior applications for patent the side cutters are 7o shown as of straight form and as having lengthwise-reciprocatin g motion. In the present construction the side cutters are circular saws having a movement in their own'planes, whereby they may be forced through the stile 7 5 at the proper point for the formation of the pocket, the stile being given lengthwise motion to extend the length of the side cuts, if required. This improvement enables the cutting of pockets in stuff much thicker than can 8o be advantageously cut by straigh t-toothed cutters, and therefore enlarges the range of usefulness of the machine. The machines of the prior patent and application are adapted only for cutting pockets. The present machine is convertible into a general sawing-machine, being constructed with a movable part or parts by which the circular 'saw is exposed in position for use for other purposes than pocketcutting. This last-mentioned improvement has of course no relation to the use of the machine as a pocket-cutter; but itis a possibility resulting directly from the use of a circular saw or saws in the machine for making the side cut or cuts of the pocket. The 95 great value of this convertible feature of the machine is due to the fact that by reason of the great capacity of the machine as a pocketcutter small factories can give it employment for only a small part of the time, and when idle it necessarily occupies valuable space in the mill. By making the machine converti- IOO ble from a pocket-cutter to a plain circular sawing machine, dado-cutter, groover, &c., it may take the place of the ordinary sawing-machine, and thus increase the productive capacity of the mill without taking up additional space. The machine may obviously have the circular saws without being convertible, and certain of the claims hereto appended are intended to protect the invention in its non-convertible form. The invention is, however, herein illustrated in con-4 vertible form.
Describing the present invention with reference to the accompanying drawings, Figure l is a rear side view of the machine. Fig. 2 is a top view. Fig. 3 is a front elevation. Fig. 4 is a transverse vertical section on the line 4 4 of Fig. l. Fig. 5 is an enlargement of cert-ain details in side view, and Fig. 6 shows a modification of certain connections.
A represents the main frame of the machine, said frame being preferably rectangular and oblong in form, as shown. A represents a separate and relatively-movable top frame composed of end castings ct a, joined by the parallel bars ct ct', separated by the openings a2.
A2 representsa table which is secured upon the top of the main frame A, with a suitable lengthwise opening d2 therein directly beneath the opening a2 between the bars a', this table A2 forming a support upon which the stile or other stuff to be operated upon may be moved or held (as the case may be) in operating thereon. Said table A2 may of course, if desired, be made either in a single piece, with the opening CL2 formed therein, or of two parts having such a space or opening between them.
B represents the main driving-shaft, said shaft being mounted crosswise of the machine in suitable bearings b b. It is here shown situated near the head of the machine,(where the operator stands;) but it may be at or near the opposite end, if preferred. This shaft has upon its projecting extremity the fast and loose pulleys b b2, which should be adapted for a four-inch driving-belt. Between its ends is the belt-pulley b2. Y
C is a rigid vibrator)1 frame having its aXis upon the driving-shaft B and having its free end extended upward in the inclined direction shown in Fig. l and adapted to rise and fall within the main frame A. Upon such free end of the vibratory frame C is mounted a horizontal saw-arbor c, arranged parallel with the driving-shaft B, and upon the projecting end of this arbor are secured in the usual or any suitable way one or two circular saws C C', which (when two are employed) are separated by a space equal to the width of the stile-pocket to be cut. The saws C are arranged to rise through the space as of the table A2 when acting upon the stile resting on said table and are adjustable on the arbor c by the usual means to permit the cutting of pockets of different widths or for other purposes. The saw-arbor c is provided with a band-pulley c', over which a suit-able belt passes from the pulley b2 on the drivingshaft B.
C2 represents a pivoted foot -lever connected by a stiff rod c2 with the free end of the saw-frame C, by means of which lever the operator may raise the saws C through the table A2 and into the stile or other stuff resting thereon, the saws being held thus elevated while the stile is moved lengthwise along against the saws when the kerfs to be made therein are required to be longer than will be made by the elevation of the saws alone. The saw-frame may descend and retract the saws by its own weight or otherwise.
D D represent two lower cross-cutters, and D D two upper cross-cutters, for cutting the ends of the stile-pocket. These cutters are shown to be vertical, as they are also shown in my said second prior application for patent, and not inclined, as shown in my first above-mentioned application. The inclination of such cross-cutters has been found in practice unnecessary and for some'reasons less desirable. The cross-cutters D and D are also here shown as being toothed saws and as being given their necessary reciprocatory movement in their own planes by the following means.
D2 is a rotating shaft situated near the back of the machine in or near the plane of the table A2, being given its motion by a twist belt trained over the-pulley d2 thereon and the pulley b4 on the shaft B, or otherwise. D2D3 are four eccentrics secured on said shaft B. These eccentrics are arranged in two pairs separated on the shaft bya distance equal to the proposed length of the pocket to be cnt, and the eccentrics of each pair are preferably arranged oppositely as to their throw.
D4 and D5 are pitmen mounted on the eccentrics D2, and at their free ends they connect with'the cross-cutters D and D', respectively. One pitman D4 proceeds from one of the eccentrics Dof each pair of the latter to actuate one of the lower cross-cutters D, and, similarly, one pitrnan D5 proceeds from the other eccentric D3 of each pair to actuate one of the upper cross-cutters D'. Said pitmen are given the downwardly and upwardly curved forms shown for the obvious purpose of clearing the table A2 and superjacent frame-bar ct', below and above which, respectively, they connect with the cross-cutters.
The cross-cutters D and D are fed into the stile and retracted therefrom preferably by connection of the free ends of the pitman IOO IIO
with cranks or eccentrics on oscillatory shafts Y arranged, respectively, below and above the cross-cutters, as best illustrated in Figs. 4, 5, and. In all figures except Fig. 6 eccentrics are shown for this purpose; but in Fig. 6 cranks take the place of the eccentrics.
D6 is a horizontal shaft mounted in the main frame A some distance below the table A2, and in line with the free ends of the pitmen DT is a like shaft mounted in the upper part of the top frame A over the free ends of the pitmen.
Describing the construction in which eccentrics, as distinguished from cranks, are employed, DS represents the eccentrics placed on the shafts D6 and D7, one above each upper pitman and one below each lower one, the upper and lower eccentrics being arranged oppositely as to their throw, as plainly shown in Fig. 4. The box-straps of the lower eccentrics D8 connect with the extremities of the lower pitmen DJl through the medium of arms d, and those of the upper eccentrics similarly connect with the upper pitmen through arms d. By these means oscillation of the shafts D6 and D7 will obviously force the crosscutters into a stile to make the end cuts of the pocket or retract the cutters after such end cuts have been made. For the purpose of simultaneously advancing and simultaneously retractiug all the crosscutters the shafts D6 and D"i are shown as having secured to their protruding ends at the head of the machine pinions or toothed segments E E, and intermeshing with these are two segments E' E2, oflarger radius, journaled on the frame. To these latter segments are secured parallel arms E3 E2, connected by a rod E4, the upper one of the arms E2 being provided with a handle E5, by which the operator may move it, and thus simultaneously rock the segments E E2 to oscillate the shafts D6 D7, and he may thus advance all the cross-cutters D D' into the stile at the same time in cutting the pocket, or he may simultaneously retract them out of the stile after the cuts have-been made.
In the modification shown in Fig. 6 the shafts D and DT have secured thereon cranks D9 D9 in place of the eccentrcs D8, said cranks being connected with the ends of the pitmen D4 D5 by means of pivoted rods or bars cl2 cl2. In this case the parallel connected arms E3 E3 are secured to the front ends of the shafts D6 D7. The crank construction last described is preferable for its greater simplicity and by reason of the less vertical movement required of the levers E to give the full desired movements to the cross-cutters.
The length of the pocket cut by the machine may be varied at pleasure by shifting the positions of the eccentrics D3 D8 (or of the cranks D5J used in place of the eccentrics DS) on the several shafts to which they are applied or by shifting such of these eccentrics as are concerned in the operation of the cross-cutters at one end only of the pocket. To this end said eccentricsv and cranks will be movably secured to the shafts on which they are mounted by any familiar or suitable means of which the set-screws illustrated are an example. The side cut or cuts made by the circular saw or saws may of course be given any desired length bylengthwise movement of the stile against said saw or saws when the latter are in action. Y
It will be observed that the machine-frame affords openings at each end beneath the top frame for the introduction and passage of the stile to be operated upon as it rests or slides along the table A2, and also that the top frame or the bars ci ct thereof may afford a bearing or rest for the upper surface of the stile when subject to pressure from below--as, for eX- am ple, when the circular saws are being forced upward through the stile. The device here shown and desirably employed for clamping the stile in place in the machine While the end cuts of the pocket are being made also presses upwardly on the stile against the resistance of t-he top frame.
In the clamping device herein shown F F are oscillatory rods arranged transversely beneath the upper surface of the table A2 and having their ends projecting at the outside of said table, where they are provided with parallel arms ff, on one of which is a handlef. These arms ff are connected by a rod f2, pivoted to both, so that the rods F F may be simultaneously oscillated by the operator using the handled one of the arms fas a hand-lever. Opposite the opening d2 in the table A2 the rods F have each one or more projecting spurs, which by the oscillation of the rod may be forced upwardly into the under surface of the stile to secure it in place or retracted therefrom to release it.
As a means for guiding or adjusting the stile in the machine I prefer to employ the gage set forth in my application for patent, Serial No. 536,611, which gage enters the stopgroove (which is always present in the stile) instead of engaging the edge of the stile. The stop-groove gage is not herein shown; but in its place is shown 'the adjustable vside gage F', Figs. 2 and 3, which also serves as a general work-gage when the machine has been converted into a plain sawing-machine, as will be hereinafter explained.
The end stop mechanism for the adjustment of the stile to position in cutting the pocket is preferably of the following construction.
G represents an apertured block adapted to slide upon the fixed horizontal rod or bar g, which is attached to the end of the machineframe in line with the table A2. In a hole in the block G is adjustably secured a rod G', the inner end of which is arranged over the table A2 in position to be struck by the end of a stile inserted into the machine from its opposite end or side.
G2 is a lever pivoted between its ends to the machine-frame and provided at its upper end with a slot through which passes a pin or bolt g', that enters the block G, and thereby enables the lever when vibrated to give movement to the block along its support g. The lower end of the lever G2 is connected by a rod g2 with the upper part of the circular-saw frame C, as clearly shown in Fig. l. In raise ing the circular saws, therefore, the lever G2 ICO IIO
will be vibrated to throw the block G rearward, and in dropping the saws said block will be moved forward or inward to the position it occupies in Figs. l and 2. It may be understood that when the block G is in its inner position, or, in other words, when the saw-frame C is down, the adjustable rod G is in proper position to gage the place of the stile to receive the end cuts of the pocket. The stile is thrust endwise into the machine far enough to commence the side cuts at the lower end of the pocket, and then after raising the saw or saws C through the stile the latter is pushed farther into the machine and against the saws until the stile strikes the stop-gage G. The saw-frame is then lowered or let fall, and in its descent it causes inward movement of the stop-gage, which pushes the stile back to the proper position to receive the end cuts. At this point the stile is clamped in place and the reciprocating end cutters caused to enter the stile. Their cuts being completed, they are retracted and the stile is released from its clamps ,and withdrawn.
It will be observed that the shaft D7, which is connected with the upper cross-cutters, and the part or parts opposed to the clampingspurs belong to the top frame A. For the purpose of exposing the circular saw or saws suitably for general or special use other than that 0E making the side cut or cuts of pockets this top frame A is made removable away from the main frame or from over the table A2, and to give ready convertibility back to a pocket-cutter this is preferably done in the manner indicated in the drawings, in which it is shown hinged to the main frame on the rotary shaft D2 as an axis. Thus connected, the top frame A may be raised to the position shown in dotted lines of Fig. 3, where it may be temporarily fastened by a detachablysecured brace-rod H during the use of the machine for mere sawing purposes and from which it may be quickly lowered when the machine is to be again used for pocket-cutting. To free the top frame, in order that it may be raised as described, the rod E4 may be detached at its upper end` from the lever Es and any fastenings employed to secure the frame A to the main frame released. The belt which drives the shaft D2 should also be thrown off. One suitable form of fastening for holding the top frame A' to the main frame A when the machine is in use as a pocketcutter is clearly shown in Fig. 3 and consists in a lug or lugs d4, depending from the top frame close to the main frame, and a bolt or pin a5, passing through the lug into the main frame.
It is evident that the detail mechanisms may be widely varied without departure from the invention, as well as that certain of the improvements set forth may be employedl without others.
