MACHINE FOR CUTTING GROOVES IN DOOR AND WINDOW STILES.

Application filed July 21, 1913.

To all whom it may concern Be it known that I, FRANCIS V. Pnnmtrs, acitizen of the United States, residing at Orlando, in the county of Orange and State of Florida, have invented new and useful Improvements in Machines for Cutting Grooves in Door and lVindow Stiles, of which the following'is a. specification.

This invention relates to improvements in machines for cutting grooves in the stiles of door and window frames to receive the headers and sills, the object being to provide an eflicientmachine which will cut the header groove and an angular sill groove at practically one operation for both right and left hand stiles, the machine being also provided with means for trimming the ends of the stiles and for making a miter cut at the header end of the stile when desired.

The machine may also be used for simultaneously cutting. any desired number of grooves crosswise of a board, the number being determined by the number of cutters employed.

The invention consists in the novel fea tures of construction and operation hereinafter illustrated, described and pointed out in the appended claims.

In the accompanying drawings Figure 1 is a front elevation of a machine embodying my invention. Fi 2 is a top or plan view of said machine. Fig. 3 is an end view thereof. Fig. 1 is a cross section taken on line a:m of Fig. 1. Fig. 5 a plan view of a portion of the left hand end of the machine with the work carriage removed. Fig. 6 is a plan view of a portion of the left hand end of the work carriage. Fig. 7 illustrates a door stile in face and edge view.

In the machine illustrated the main frame consists of a rectangular casting comprising a front rail 1, a rear rail 2, and connecting end rails 3, said casting constituting the bed of the machine which is mounted upon standards 1 and 5. Slidably mounted upon the front rail 1 is a hollow standard 6 forming the support for one end of a cutter shaft 7, the opposite end of said shaft being journaled in a standard 8 which is longitudinally adjustable on the rail 1, and

which is locked in adjusted position by a set screw 9. The sliding standard. 6 is provided at its base with projecting flanges 10 which slide in guides 11 secured to the frame rail 1, and is also provided with Specification of Letters Patent.

spaced bearings 12 for the shaft 7, a driving pulley 13 being mounted on the shaft between said hearings, as best shown in Figs. 1 and 41.. The shaft '7 is also provided with fixed collars l l on the outside of the bearings 12 so that the shaft will be moved longitudinally by sliding movements of the standard 6. The standard 6 is moved by means of a hand lever 15, which is pivotally mounted on the frame "ail 1 and connected to the standard by a link 16.

On the shaft 7 is mounted one or more cutter heads 17 of any approved type adapted to cut a groove in a stile properly presented thereto. Only one of such cutter heads is shown, but others may be mounted on the shaft 7 when it is desired to cut more than a single lateral groove at right angles to the stile. The cutter 17 is secured to the shaft to rotate therewith. For the protection of the operator a guard 18 is adjustably mounted on the frame rail 1, said guard partially housing the cutter and bolted thereto is a support 19 upon which the work rides in passing over the cutter.

Mounted on the rail 2 of the main f ame is a swiveled standard 20 which supports a cutter shaft 21 so that said shaft and cut ter may be turned to any desired angle with respect to the shaft 7. The standard 20 is cylindrical in form and is provided at its base with an annular flange 22 which is housed within a ring 23 secured to the rail 2, as clearly shown in Fig. 4. The shaft 21 is mounted in spaced bearings 24 formed on said standard, and a driving pulley 25 is mounted. on said shaft between said bearings. The shaft 21 carries a cutter head 26, which cuts the sill groove in the stiles, and said shaft may also be provided with a circular saw 27 as illustrated in Fig. 5, for cutting off the end of the stile.

The cutter shafts 7 and 21 are driven from the main driving shaft 28 which is mounted in a bearing in the frame standard 41 and having its inner end iournaled in a bracket 25) bolted to the frame rails 1 and 2. The shaft 28 is provided with a fast pulley 30 to receive a driving belt, and is also provided with a loose pulley 31 to which the driving belt may be shifted to stop the operation of the machine, as is usual in machines of this character. A pulley 32 is mounted on the shaft 28, said pulley operating to drive the cutter shafts by means of a V The belt 33 passes under the pulley 32 and over the pulleys 13 and 25 on the cutter shafts and between said last mentioned pulleys the belt passing downwardly beneath an idle. pulley 34, all as clearly shown in Fig. 4.

A guide 35 is fixedly mounted on the standard 6 above the driving pulley 13, said guide consisting of a rail provided with a groove 36 and arranged at a rightangle to the shaft 7. A similar guide 37 is fixedly iounted on the standard 20, said guide also consisting of a grooved rail arranged at a right angle to the shaft 21. These two guides are pivotally connected together, as at 38, midway between the two shafts 7 and 21 to form a continuous guide across the two cutter shafts for controlling the work holding means, as will be hereinafter described.

It will now be noted that when the standard 6 is moved by the hand lever 15, motion will be communicated to the swivel standard 20 through the guide rails 35 and 37 just described, and that the cutter shaft 21 may thus be moved from a position parallel to the cutter shaft 7, as shown in Fig- 5, to a position angular thereto, the direction of movement depending upon the direction of movement of the standard 6. The limit of angular movement in either direction is regulated by adjustable stops 39 which limit the movement of the standard 6. As hereinbefore described, a movement of the standard 6 carries with it the cutter shaft 7. These parts may be locked in adjusted position in any desired manner. As shown, they are locked in adjusted position by means of the standard 8 and its set screw 9, said shaft being secured against longitudinal movement with respect to said standard by collars 40 as shown in Figs. 1 and 2. lVhen an adjustment of the standard 6 is to be made, the set screw of standard 8 is released to permit said standard 8 to move on the frame rail 1, said standard being thereafter locked in position as will be read ily understood.

The work carriage is slidably supported upon guide rails 4.1 mounted upon standards 42 at each end of the machine, said rails being provided with a groove 43 to receive a roller carriage 44, the latter forming a roller support for the work carriage. Said work carriage consists of a pair of grooved rails mounted upon a roller carriage 44 at each end of the machine, said rails 45 being connected together by beams 46 and 47 which are spaced apart sufiiciently to re ceive between them the board or stile to be operated on.

Mounted on the inner face of the beam 46 is a rock shaft 48 which is slidably mounted in bearings 49. Said shaft carries work supports 50 and 51 upon which the board or stile is clamped. Said supports are each mounted on the shaft 48 between fixed collars, 52 so that any movement of the support 50 to the right or left will be communicated to the support 51, the shaft being at all times free to be rocked in its bearings independently of said work sup ports. The work support 50 is provided on its under side with a roller 53 which travels in the groove 36 of the guides 35 and 37. The support 51 has its free end bent upwardly and over the upper edge of the beam 47 upon which it slides, and said support is also provided with a projection 54 which serves as an abutment or end guide for the work. Said support is adjustable on the shaft to suit requirements by adjusting the collars 52 between which said support is mounted. An adjustable guide 55 is also provided on each of the work supports 50 and 51 against which the side edge of the work is adjusted.

The work is clamped on the supports50 and 51 by means of clamping arms 56 which are fixedly mounted on the shaft 48 and which are provided with adjustable pointed bolts 57 which are pressed into the work by means of a handle 58 also fixedly mounted on. said shaft.

In Fig. 7 I have illustrated a stile 59 having a straight groove 60 at one end to receive the header of a door or window frame, and having an angular groove 61 at its opposite end to receive the sill. The end of the stile adjacent the groove 61 is cut parallel with said groove. To cut the grooves and angular end of this stile, the standard 6 is moved to the left by means of the hand lever 15. This moves the work guide 37 to the angular position indicated by the dotted lines 62, the shaft 21 being moved to the angular position indicated by the dotted lines 63. The work support 51 is then adjusted for the length of stile desired, and the cutter head 17 is moved in proper position for cutting the groove 60. The machine being in operation the board is placed upon the work supports 50 and 51 with one end of the board in contact with the end abutment 54 and its side edges against the guides 55. The clamping arms 56 are then pressed against the work by means of the handle 58, the pointed bolts 57 operating to firmly grasp the work and hold it in posi tion against the work supports 50 and 51. The entire work carriage is now moved across the machine by means of the handle 58. The work is guided across the groove cutting head 17 for cutting the straight groove 60 by means of the guide roller 53 mounted on the under side of the work support 50, this roller operating in the slot 36 of the guide 35, the work holding means being thereby held stationary with respect to the carriage while passing over said cutter. As the carriage advances roller 53 enters the slot 36 of the guide 37, and as the latter is in angular position the work holding means is then moved longitudinally with respect to the travel of the carriage, the work being thereby presented to the cutter head 26 to out the angular groove 61, the work traveling across said cutter in a direction angular to the direction of travel of the work carriage. When a saw 27 is employed, this operates simultaneously with the cutter head 26 to trim the end of the stile angularly as illustrated in Fig. 7. After the work has been passed over both of the cutters, the operator pulls back on the handle 58. This rocks the shaft 458 to release the work clamps, and a continued pull on the handle draws the carriage back for the next operation. For ejecting the work from the machine I employ a gravity latch 6t mounted on an extension 65 of the work rest 19. A similar latch 66 is mounted 011 a work rest 67 adjacent to the cutter head 26. Said latches project above the work rests, and as the work passes thereover it presses down said latches which are thereafter raised by their weighted ends 68 so as to engage the work and prevent its return by carriage, this being a well known means for the purpose stated.

Should it be desired to cut a right hand stile, the guide ways 35 and 37 are moved to the positions indicated in the dotted lines 69 in Fi 5, the operation of the machine being precisely the same exceptthat the work holding means is guided in an opposite angular direction over the cutter head 26 to cut a groove 61 to an angle opposite to that shown in Fig. 7.

It will be readily understood that as many straight grooves as may be desired may be out crosswise of a board by the employment of additional cutter heads 17 on the shaft 7 and should no angular grooves be desired the guide ways 35 and 37 will be arranged in line with each other as shown in full lines in Fig. 5.

l/Vhen it is desired to miter one end of the board or stile a circular saw 70 is employed, said saw being mounted upon a standard 71 on the frame rail 2, said standard being adjustable on said rail and being locked thereto by a set screw 72. The shaft 73 which supports the saw is journaled in a yoke 74L which is adjustable with reference to the standard 71 for permitting the shaft and saw to be moved at any desired angle as clearly illustrated in Figs. 1 and 2. The shaft 73 is provided with a driving pulley 7 5, said pulley and shaft being driven by a belt from a pulley 7 6 mounted on the shaft 7. Said saw is designed to be used in straight work only, that is, work in which there are no angular cuts to be made by the cutter head 26. The saw 70 may be arranged at an angle of 45 for making a miter cut or may be arranged in an upright position for making a straight out, and if the guide ways 35 and 37 be arranged in alinementwith each other, the saw 27 may be used to trim the opposite end of the work as will be readily understood.
