A TTORNEY Patented are 3, 1%53 nurse sta ADJUSTABLE TEMlLET FOR MOB/RISING DQORS AND DGUR JAMES 6 Claims.

This invention relates to adjustable means for gaging the recesses on door edges, such as for door hinges and for lock plates, and on door j ambs whether plain or rabbeted.

The objects of my invention are, to provide a simple device, for use especially in door factories, which can be quickly and accurately placed and clamped on the edge of a door, or a door jamb, or with certain attachments may be applied to a rabbeted door jamb which when once adjusted for performing its function on a certain type of work on a door, can be used on the same type without further adjustment on any number of similar doors, as is usually required in factory operation; which can be adjusted to provide the gage or templet in which the router will work to chip the door edge for the hinge leaves or for the lock plate; which is adjustable for the various thicknesses of the wood to be worked on; which is provided with improved means of gaging the distance from the end of the door to the hinge; which is held firmly on the door by a quick acting clamp; in which the clamping flange is adjustable in its position relative to the clamping eccentric, but is always parallel with the door; which is simple in construction, easy and quick to apply to the door or jamb, and which effectually forms a gage and templet for the hinges and the lock plate mortises.

A further object is to improve the means of controlling the adjustable plates of the templet.

I attain these and other objects as will readily be perceived by those skilled in the art, by the devices, mechanisms and arrangements illustrated in the accompanying drawings, in which- Fig. l is a bottom plan view of my improved :templet and gage; Fig. 2 is a side elevation, taken on the clamp side and applied to the hinge edge ot a door; Fig. 3 is a cross-section thereof, taken the line -3 in Fig. 1; Fig. 4 is a perspective view the clamp plate and flange; Fig. 5 is a view similar to Fig. 1, showing the templet and gage with the attachments thereon for routing a rab steel door jamb; Fig. 6 is a section thereof,

on the line 5-6 in Fig. 5; Fig. 7 is a perspective View showing parts broken away to reveal the construction; and Fig. 8 is a perspective view of the clamp plate used in connection with rabbeted door j ambs.

Identical numerals of reference refer to the parts throughout the several views.

In door factories it is common practice to dap the edges of the door, and the door jamb, for the leaves of the hinges, and for the lock plate of the door. My templet is intended for use in a door factory to standardize the work and to provide a very quickly and accurately applied templet on which the router may work so that the several recesses will be in exactly the correct positions and of the desired dimensions and depth.

Referring to the drawings, it will be seen that this templet comprises a rectangular body composed of two similar members Ill and I I, suitably secured together by means of four screws located at the corners. The shape of these members It and H is, in plan, a rectangular ring with a clear rectangular opening I2 at the cen-- ter, said opening being elongated with its sides parallel to the side edges of the parts I8 and II.

The members Ill and It are in the form of flat plates, the lower side of the plate I I being adapted to rest on the edge of the door to be clapped, while the upper side of the plate I0 is adapted to support the electric router as it is moved thereon.

Each of these members It and i I is provided in their adjacent and contacting sides with a shallow groove or guide slot, having parallel sides and extending across the said member It! or II, said grooves bein adapted to receive and confine the movable members of the templet which limit the extent of the movement of the router on the member Iii.

Four or" these templet plates are provided and 1 each is separately adjustable in its guide slot toward or away from the central opening I2. The upper member I0 is provided on its under side with the shallow guide slot lit at each end, said slot being as broad as the breadth of the opening E2. The two end templet plates I l fit therein and are adapted to be moved to reduce or expand the free length of the said opening. Similarly the lower member II is provided with a shallow slot or groove I5 extending across it and having parallel sides and being as broad as the length of the opening E2. The two side templet plates I5 fit in said slot I5 and are adapted to be moved therein to reduce or expand the width of the said opening I2.

Each of the four plates is and I5 is adjusted in its position in the respective slots 53 and I5 by means of a threaded non-rotatable bolt l1 attached to and extending outward from the center of the plate, and a suitable nut i8 is mounted on the said bolt ll. These nuts it do not move longitudinally on the said bolts when they are turned but are held from such movement by being grooved and lying in a complementary groove in the said templet body, thus turning the nut I8 draws the bolt l1 thereof and its attached templet plate M or it into or outward from the center of the templet. The said plates are positioned above the level of the door edge in a position adapted to be engaged by the roller guide usually mounted on the router tool. The router tool extends down from the top surface of the templet a predetermined distance in order to cut the hinge recess the desired depth.

The lower side of the lower member ll of the templet is provided with a series of parallel grooves 19 on one of the long sides thereof, opposite to the side with the clamping eccentric, hereinafter described. These grooves 19 are rectangular in section and are all parallel with the sides of the templet.

A flange plate 20 (Fig. 4) is provided with a pair of long coaxial keys 2| adapted to fit in any of the said grooves l3 and to hold its vertical clamping flange 22 parallel with the templet sides. This plate 26 is provided with a slot 23 at its center, said slot being elongated and extending at right angles to the key 2|, through which the stud 24 passes to secure it to the under side of the member I l, with its key 2| in the selected groove 19 to hold the flange 22 at the desired distance from the opening 12. This flange is adapted to engage the side of the door to form one member of the clamp.

The other side of the opening l2, opposite to the clamp grooves Hi, the plate H is provided with a series of holes 26 (Fig. 1) all of which are threaded and are adapted to receive the pivot pin 2'! on which the clamping eccentric 28 is mounted. These holes ar at varying distances from the central opening l2. The eccentric 28 is provided with a suitable handle 29 by which it is turned on its pivot pin 27. The eccentric 28 is preferably circular in form with the pivot pin 21 passing through a non-central hole therein.

The templet is secured in place on the edge of the door 25 by placing the flange 22 against the side of the door and then clampin it by swinging the eccentric 28 against the other side of the door.

The distance from the end of the door to route for a hinge leaf is gaged by a rod 30, adjustably mounted in the two ribs 3|, which join the plate 20 to the flange 22, by passing through coaxial holes therein and are held in such adjusted position by suitable set screws 32. The end 33 of the rod is turned at right-angles and is adapted to engage the end of the door 25. Thus the position of the templet on the door, and the size of the routed area, is determined by the rod 30 and the plates l4 and I6, and once determined and adjusted may be applied to all doors of the same size without change.

Considering now the form of my invention illustrated in Figs. 5-8 which is adapted for use in making the recesses for the hinge leaves on a rabbeted door jamb. The upper portion of the templet is the same as above described, but the flange plate 20 with its flange 22 has been removed and are substituted by the gage plate 34, and the clamping eccentric has been removed from its place.

This gage plate 34 comprises a side part having a key 35 adapted to enter any of the above described grooves l9, and a slot 36 corresponding with the above described slot 23. Two arms 31 extend laterally out from the ends of the plate 34, said arms resting on the jamb 38 and butting against the rabbet shoulder 39 and form one member of the clamp.

A plate 40 is secured to the Side edge of the members In and H, opposite to the above plate 34, by means of suitable studs, and is provided with a flange 4| extending outward therefrom. This flange 41 is provided with a plurality of threaded holes 42 at varying distances from the Opening I2 and are adapted to receive the pivot pin 43 on which the above described eccentric 28 is mounted.

The arms 31 are provided with coaxial holes therein adapted to receive the gage rods 44, which are secured in position therein by the set screws 45.

Thus it will be seen that a rabbeted door jamb may be dapped to receive the hinge leaves, by clamping the templet to the side of the door jamb between the ends of the arms 31 and the eccentric 28, and applying the router to the top surface of the member [0 of the templet.

It is to be understood that I claim as my invention all changes or modifications of the above described apparatus selected for disclosure, which do not depart from the spirit and scope of my invention as outlined in the appended claims.
