I To all whom it may concern:

Be it known that I, Gnonon DnnNNnn, a citizen of the United States of .Ai'nerica, residing at P010, in the county of Ogle and State of Illinois, have invented an Adjustable and Reversible Measuring and Gaining Machine, of which the following is a full, clear, and exact description.

This invention an apparatus for use in making window or door jambs, and the object of the invention is to provide means whereby the transverse grooves near the ends of the amb may be accurately located and rapidly produced.

The invention seeks to provide a device by which a workman may produce the gains or grooves in any width or length of a window or door jamb without previously measuring or laying off the jamb.

A. further object of the invention is to provide means for cutting the groove or gain in a amb at a right angle to the longitudinal edges of the jamb or at any desired inclination thereto, and to provide for the formation of the right or left jamb with equal facility.

A further object of the invention is to provide a device in which jainbs of any desired thickness may be easily made and uniformity in the location of the gains attained.

All these objects, and such other incidental objects as will appear as the nature of the invention is more fully understood, are attained in the use of the apparatus illustrated in the accompanying drawings, and the invention consists in certain novel features thereof which will be hereinafter fully described and then more specifically pointed out in the appended claims.

In the drawings,-l igure 1 is a plan view partly broken away, of an apparatus embodying my invention. Fig. 2 is an elevation of the apparatus with a part shown in vertical section, as viewed from the right hand end of Fig. 1. Fig. 3 is a transverse vertical section through one of the clamping guides or gages, the device being reversed from the position occupied in Fig. 2, that is, looking toward the right of Fig. Fig. 4 is an enlarged bottom plan view of one of the adjustable clamps. Fig. 5 is a detail section on the line 55 of Fig. 2. Fig. 6 is a detail section on the line 66 of Fig.2. Fig. 7 is a plan view of the lower member of the adjustable clamp.

In carrying out my invention, I provide a support consisting of end frames 1 adapted to be rigidly secured to a work bench or other fixed support and provided with recesses at their upper corners in which are secured the ends of angle bars 2 which extend between the two end frames and serve to rigidly connect the same. The angle bars 2 are in parallel spaced relation and form the front and back of the supporting frame and also serve as guide rails to which adjustable clamping gages are secured. These gages, which may be practically identical one with the other, each comprises a base plate 3 of substantially T-shape and is provided on the face constituting its under side, when the parts are in operative position, witlrdepending lips or hook-shaped lugs l adapted to engage the inner edges of the front and rear rails 2, as shown clearly in Figs. 3 and 1, and near its rear end the base plate is provided with a lug or stop 5 adapted to bear against the back of the rear rail 2, as will be readily understood. At its rear extremity the base plate is provided with an opening or passage 6, the purpose of which will presently appear, and the front end of the base plate is formed into a laterally broadened head 9 having a curved front edge 7 in which are formed a plurality of notches 8, the opening 6 being the center of the are described by the curved edge 7.

On the underside and intermediate of the head 9 of the base plate is a depending lug or bracket 10 in which is mounted a thumb screw 11 adapted to bind upon the front face of the front rail 2 and thereby secure the said base plate at any point along the supporting frame, the corresponding lugs 4t engaging the rear edge of the front rail 2, wherefore the single screw 11 serves to very firmly hold the base plate and parts carried thereby in adjusted positions. Resting upon the base plate 3 is a clamping bar 12 constituting the lower or end member of a clamp, and this bar has on its upper surface near its rear end a pin or spur 13. The bar 12 is secured to the base plate 3 by a pivot bolt or screw 14 passing through the opening 6 in the base plate and engaging the clamping bar 12 immediately under the said spur 13. On the under side of the bar 12, near the front end thereof, I provide a pair of longitudinal ribs 15 between which a latch 16 is pivotally mounted. This latch is provided at its rear end with a tooth 17 adapted to engage one of the notches 8 in I the head 9 of the base plate, and the front end of the latch is formed into a finger piece 18 by which itmay be conveniently operated. 'A spring 19 is' disposed between the clamping bar 12 and the latch 16 in advance of the pivotal support of the latch in order to hold the rear end of the latchnormally in engagement with a notch 8. On one side edge of the 'bar- 12, at the rear end of the same, I provide a, guide 20; having ribs 21,011 its outer face, and a bolt 22 is mounted in this guide near the upper end O t a t Project thr ugh longitudinal; slot 23 in an arm 24; secured to; an upperclamping bar 25, a thumb nut 26, being monnted on the bolt 22 and adapted to, b turned homev against the arm to. secure the same at any desired position of adjust: ment so that the. space between the clamp.- ing bars 12' and 25 will accommodate jambs of any desired thickness. The clamping bar 25 has practically the same dimensionsas the clamping bar 12;, but the upper bar is preferably of wood while the lower bar is preferably of metal. This construction is, strong and rigid and; will permit. the door jamb to. be securely clamped in posi: o n h appara us, Whi a the same time e pper bar wi n t injnre that face of the ja nb which is exposedin use and will not break or otherwise injure the. cutter when the same is manipulated by a careless or inexperienced workman. The front end of the upper clampingbaris held to, the IOWer bar, to. secure a] jamh between them, by means of a holding device comprising a bolt or pin 27 secured one end in a bracket 2S, secured; upon the upper c-l ang ps ing bar and projectinglateralily' from one long edge thereof, the lower end of the pin passing'through a lug or ear projecting from the like edge of the lower clam-pingbar directly under the bracket 28, as shown clearly in Figs 2- and 5. A spring 302 sur rounds the bolt; or pin 27 between the two. clamping arms and tends, to move the upper clamping bar away from the lower champingbar, and a set screw 31 is mounted in the lug or ear 29 to bear against the bolt or pin 27 to hold the same in adjusted positions.

A clamp consisting of the base plate or carrier 3,]lower clamping bar 12, and upper clamping bar 25 and their connections, as above described, is provided for each, end of the j'amb and one of the clamps, desig nated 32 in Fig. 1;, is intended to remain fixed, relative to the supporting frame, after having been once adjusted and securedthereto, while the other clamp, designated 38' in Fig-. 1, is intended; to be adjusted from time to time along the frame to accommo- :QOllStlLlCtlOIl. and compact in the arrange e, j mbs of d f ren l ngths. To insure accuracy in the adjustment of the clamp,

the front rail 2 of the supporting frame is provided on its upper face with a series of grad'uations 34 in accordance with standard frames. or j ainbs to accurately locate the adjustable clamp according to the length of j ainb tov be made. Two scales are provided,

the front scale being graduated for singlelight Windows, and the rear scale belng graduated for double-light WlDdOWS. A

'jalnb 35 is inserted under the. upper clamp:

ing bars with one edge, to constitute the outeredge :tor use resting against the spurs. or stops 13 of the lower clamping bars. and one end the proper distance from the re. pective c amp, this distance being ascere tained by measurement, or by a suitable in: dication on the machine. The. upper clampng bars. are then brought down firnah up the upper surface of the jamb. and: secured by tightening the thumb. screws 31. The clamp, appearing at the left in Fig. l and designated 32', is ordinarily set at" a right angle to the outer edge of" the j amb, by engaging the latch 16. in the central notch 8 and: the. left hand straight edge of the. upper bar 25 of this clamp, as viewed in 1 will serve as. a guide or gage against which the dado cutter may be supported; when moved across the jan b so. as to cut a groove or gain 36 therein. The proper position for the clamp 32 is indicated by the. lines on the graduated bar 2. The clamp 33. is adjusted to the desired angle by engaging the latch 16 thereof in the proper notch 8* of the base plate of the clamp, and the left hand; straight edge of the upper bar of this clamp likewise serves as a guide for the cutter while producing a groove The j m s ne ide ofthe. windowshaving' been grooved or gained in this manner, the right hand clamp is set at a right angle, while the left hand Clampis at the same inclination formerlygiven the right hand clamp. The jiambs for the opposite sides of the. windowv may then be produced by moving the cutter across the jamb while resting: the same against the. edges of the upper clamping barsv in. the manner previously described.

YVhen a jamb has been finished, the set screws. 3-1 of; the clamps are released and the springs 30 at once throw the front ends of the upper clamp ng bars from the iambs so that the latter be easily removed. The

upper clamping barmay be adjusted to and from the lower clamping bar so as to. accommodate jambs of different thicknesses by loosening. the thumb nut 26, then raising or lowering the upper her, and then turning the thumb. nut home aghinst the dependent arm 24: so as to secure the upper clamping arm in its. adjusted position.

My device is exceedingly simple in its ment of its parts so; that it will not easily get out of order and may be quickly adjusted to the requirements of any particular case.

l Vindow or door jambs of any standard length or thickness may be rapidly finished by the use of the apparatus, and its many advantages are thought to be obvious without detailed mention of the same.
