TEMPLATE FOR LOCK PLATE MOHTISES Filed May 20. 1930 zagz 521 z5 w W 51V/ 'f3 E 1E- E I N V EN TOR.'

A TTORNEY'.

Patented Apr. 10, 1934 UNITED STATES PATENT OFFICE 13 Claims.

This invention has for its object to provide a simple, eiiicient and readily operated template for locating the mortise in the edge of an element, as a door, to be provided with a mortise for receiving a lock plate, it being understood that door locks are set in recesses or mortises in the edge of the door so that the plate is flush with the edge surface of the door.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all the views.

Figure l is an elevation of this template. Figure 2 is an end view looking downwardly or upwardly showing the same applied to an element, as a. door, which is shown in section. Figure 3 is a sectional view on line 3-3, Figure 1.

Figure 4 is a fragmentary sectional view on line 4 4, Figure 1.

Although this template is particularly adapted for locating the mortises for lock plates, it will be understood that it is equally as useful in locating the mortises and recesses in the edges of any other element.

This template comprises generally a body, mortise locating gages carried by the body and adjustable to determine the length and width of the mortise and means for supporting the body on the edge of the door or other element with the gages overlying the edge of the door and for centering the gages so that the mortise will be located in the center or any other predetermined position in the edge of the door, during the operation or the supporting or clamping means.

l designates the body which may be of any suitable form, size and construction, it being here shown as a plate rectangular in form with angular marginal anges 2 so that the body is in the form of a hollow pan, It is also provided with a lengthwise slot 3 in the bottom of the pan. The gages include

side gages

4, 5 and

end gages

6, 7. 'Ihe side gages 4, 5 are adjustable toward and from each other to determine the width of the mortise and one of the end gages is adjustable toward the other which is fixed for determining the length of the mortise. The side gages are connected through one of the end gages so that the adjusting movement of either side gage is transmitted to the other.

In the illustrated embodiment of my invention, each side gage is supported by a pair of

links

8, 9 pivoted at like ends at 10 to one of the side gages and at their other ends at 1l to the body, the links and the gages being arranged so that the gages always move parallel to ythemselves and to each other. Obviously, movement of the links in one direction will move the

corresponding gages

4, 5 outwardly away from each other and movement in the other direction will move them inwardly toward each other. One of the end gages as 6 is iixed in any suitable manner as by rivets 2 to one of the side gages as the gage 4 and is connected to the other side gage as 5 by an adjustable or pin-and-slot connection consisting of a slot 13 in the gage 6 and a threaded pin or screw 14 extending through the slot and 70 threading into the gage 5, the screw having a. finger piece 15 at its outer end.

7 designates an adjustable end gage which is here shown as adjustably secured to one of the side gages, as the side gage 4 and as slidable along the other side gage 5. The end gage 7 is here shown as held in its adjusted position by a clamping screw 17 extending through the gage 7 and threading into a block or jaw 18 which clamps the underside of the side gage 4, the jaw 18 being provided with a tenon which interlocks in a groove in the underside of the gage 4. By loosening the screw 17, obviously, the end gage 7 can be slid along the side gage 4 to any desired position. Obviously, by loosening the screw 14 and moving either one or the other of the side gages 4 or 5, the movement thereof will be transmitted through the connection 6 to the other gage and then when the screw 14 is tightened, the side gages will be held in their adjusted spaced apart position, thus determining the width of the mortise and then by loosening the screw 17, the end gage 7 can be moved toward or from the end gage 6, thus determining the length of the mortise.

The means for supporting the body on the edge of the door or other element, as here illustrated, comprises a pair of movable parts, as jaws, located at each end of the body, and means for operating the jaws and holding the body centered relatively to the edge of the door or for operating the jaws, permitting the body to remain stationary.

20 and 21 designate the jaws of each pair, there being a pair at each end of the body, these jaws being arranged to clamp the outer and inner sides of the door. The operating member is shown as a screw common to the jaws of each pair, the screw having right and left screw threaded connection with the

jaws

20, 21 respectively. The

screw is held from endwise movement relatively to the body so that when the screw is turned, the jaws will move toward or from each other, and hence the body and side gages are held centered relatively to the edge of the door.

22 designates the screw or operating member having a handle 23 at one end. `The means for holding the screw from endwise movement is here shown as a collar 24 fixed on the screw and coacting with thrust bearings connected to the body. As here shown, the collar is located in a slot formed in a block 25 which is secured to the end of the body, there being a block 25 at each end of the body. Each of the

jaws

20, 21 is provided with means for slidably interlocking with the block or extensions 26 thereof to hold the jaws from turning during the turning movement of the screw 22. In order that the body may conform to the bevel of the edge of the door, the body is connected to the blocks 25 by swivel joints 27.

In operation, the location of either the upper or lower end of the mortise may be located by drawing a line on the edge of the door. We will assume that this line indicates the upper end of the mortise. The length and width of the mortise is determined by the length and width ofthe lock plate or other member to be set in the mortise. This factor having been determined, the operator loosens the screw 14 and adjusts the

gages

4, 5 so that they are separated a distance equal to the width of the lock plate plus sufficient minimum clearance for the tool used to cut the recess. He then tightens the screw 14 maintaining or locking the side gages 4, 5 in their adjusted position. He then adjusts the end gage 7 toward or from the gage 6 and in accordance with the length of the lock plate plus suihcient minimum clearance for the tool. The clearances are about one-sixteenth of an inch. He then places the template on the edge of the door with the edge of the end gage 6 in line with the line before referred to, which has been previously placed on the door. If the edge of the door is bevelled, the body is turned so that the plate lies flatwise on the edge of the door, the swivel joints 27 permitting this turning.

The bevel is so slight that the turning of the body about the swivel joints does not upset, to any practical extent. the centering of the mortise or does not materially displace the gages, or in other words, because the bevel is so slight, the gages can be set to locate the mortise in the center of the edge of the door as if the edge of the door were not bevelled and the location of the mortise will not be upset by the slight bevel. During the tightening of the operating members 22, the

jaws

20, 21 are drawn toward each other clamping on opposite sides of the door without shifting the body to the right or left or upsetting the central location of the mortise or the gages which determine the position of the mortise. After the template has been applied, and hence the mortise located, the mortise can easily be routed out by suitable tools, as for instance, a router, set to a certain depth and guided by the pan with the angular flanges 2.

This template is particularly advantageous in that it is readily applied to the door or other element and accurately adjusted to the size of the mortise to be cut and accurately located or centered on the door or other element.
