DOOR AND WINDOW CATCH.

Application filed July 30, 1921. Serial No. 488,523.

T 0 all whom it mag "concern Be it known that I, ALTER Gr. ScHnRnR', a citizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented a certain new and useful Improvement in Door and Win dow Catches, of which thetollowing' is a full, clear, and exact description, reierence being had to the accompanying drawings.

This invention relates to builders hardware and has for its object the provision of a simple and inexpensive cont-rivance which can be used. as a catch, stop, lock, or'check for windows and light doors and .a base stop and retainer for heavier doors. When used as a window stop the device has the advantage ofeither locking the window shut or at any desired width of opening; and when used on doors, particularly on screen doors, of preventing objectionable slamming of the same, holding the same against rebounding or being blown open, and enabling the same to be locked when desired. Other objectsand advantages will become apparent as the description proceeds, prominent among which are the cheapness and simplicity of the device. 1 In the drawings accompanying and forming a part of this application I have illustrated a few simple embodiments of my inventive idea wherein Fig. 1 illustrates one model of my device as arranged as a basestop for a house door and a means for bold.

ing the same open; Fig. 2 is a longitudinal sectional view corresponding tothe line'2-2 of Fig. 2; Fig. 3 is a plan view of one side of said device showing the mechanism in place; Fig. 4 illustrates a part of a double hung window illustrating the mode of applying my improvement thereto; Fig. 5 is a horizontal sectional view corresponding to the line 5-5 of Fig.4; Fig. 6 is a side ele vation of the catch member; Fig. 7 is a sectional view corresponding to the line 77 of Fig. l; Figs. 8 and 9 illustrate modified; forms of my improved stop.

Describing the parts by reference characters, 1 represents the free stile of a house door and 2 the base-board. To the door is secured a strike-plate 3 and to the baseboard the stop device of my invention which comprises essentially a ball 4 supported at a distance from the base-board and parallel thereto and laterally yieldable so' as to ride over the strike-plate and spring into a hole or socket 5 with which the same provided.

This strike-plate may take any convenient or suitable formso long as it has a portion to ride over the ball and a socket to receive said ball, the L-shaped arrangement here shown being thecheapest and most easily applied since it needs no cutting of the door, although other forms can be used.

The base portion of the device is preferably made of two reversely " symmetrical castings 7 and 8 provided with suitable pins and sockets 9- 9 whereby they are held in register, and with a rivet 10 whereby they are held together. At one end these castings are formed with base flanges 11-11 for the reception of the screws 12, and at the op posite end with the hollow channels 18-for the receipt of the spring 14 and the ball 4:, the latter projecting partly through a tapering aperture 15 formed in the wall. I have shown the side of the casting below the ball as formed with a rigid abutment 16 constituting a stop-for the door, and the base as formed at the opposite side with an extended portion 17to hold the device steady against the thrust of the spring.

' For use on windows,-screen doors, and cupboard doors, 1 preferably make the device considerably smaller and lighter as shown in Figs. 4: to-7, inclusive, wherein 20 represents a trough-shaped casing having an open bottom 21 formed at each side with an attaching ear 22, one end ofthe trough being enclosed by the web 23 and the opposite end having afltaperedaperture 2-1 receiving the ball 25. Immediately at the rear of this ball the casing walls are formed with transverse slots 26 in'which is slidably mounted the metal plate 27 having at one point therein a recess 28,the movement of the plate being limited by the laterally turned ears 29 29. This plate is located so close to the ball 25 that depression of the ball is I prevented excepting when the recess 28 registerstherewith. This recess need not be as large as the ball s nce it is never necessary for the 'ball to be moved therethrough. A

spring 30 is preferably employed to hold the ball advanced, (although not necessarily so in case the device is to be used solely as. a lock) and in order to enable the plateto slide easily a second ball 31 is preferably interposed between the spring and plate; advantage may be taken of said second ball to hold the plate against accidental displacement by forming the latter at one side of the recess 28 with a shallow socket 32 for the reception of this ball. The balls and spring are held in place by a separate plate 33 pressed into the open mouth of the easing. In fact the slot 26 can also be formed by casting and the plate 27 inserted edgewise and held in place by the same bottom plate.

When used with a window the casing is secured to the top of the lower sash 36 in line with the side-stile of the upper sash 37, this stile being provided with a suitable strike-plate 38 having sockets 39 therein for the reception of the ball 25. The best and most desirable plan is to make this strike of a brass strip of the desired length having recesses at the different points where it is desired to hold the window, for example, entirely closed, open two inches; open six inches; open one foot; although a cheaper way is to use a. separate strike-plate'at each point. It will be understood that the locking effect of this device will be secured with equal security whether the spring 30 and ball 31 are present, or not, although with their presence it becomes easier to position the two sashes in the desired positions relatively to each other.

When employed with a screen door the device is preferably attached to the free stile, and the strike-plate is attached to the doorjamb; and in this case the spring 30 is very desirable because of the fact that under its influence the ball constitutes both a catch and an automatic check.

The devices shown in Figs. 8 and 9 are modifications of the device shown in Fig. 1 and are adapted to cooperate with doors for holding them open, the device shown in Fig. 8 being secured to the floor so as to engage the bottom of the door, and that in Fig. 9 being attached either to the floor or to the base-board. Each of these devices is made of a piece of steel tubing 40 having one end swaged inwardly as at 41 for the reception of the ball 42, and the other end being welded to a circular base plate 43. The spring 44 is held in place by the disk 45 and pin 46.

It will be understood that I do not restrict myself to cast metal as a construction material nor to any of the details of con- I struction nor arrangement herein shown or described except as the same are specifically recited in the annexed claims or rendered necessary by the prior art.

Having thus described my invention what I claim is:

1. In a device of the character described, the combination, with a hollow, two-part body split along a median line and having a base adapted for attachment to a supporting surface, each part having therein a semicylindrical cavity one end of which opens through a wall of such part at a distance from the base, said cavities co-operating to form a recess whose axis is parallel to the base of a spring pressed member located in said recess and movable in a direction substantially parallel thereto, said member hav ing a round nose projecting from said body adapted for engagement with a cooperating movable member.

2. As an article of manufacture, a twopart body having a base and a hollow elongated socket therein at one side of and parallel to said base, the line of separation of said two parts intersecting said socket, said socket having an opening at one end and the other end being closed, a movable memher located in said socket and having a rounded nose projecting through said opening, a spring in said socket behind said memher, and means clamping said two parts together.

3. The combination with a door and a base board, of a strike plate carried by the door, and a casing carried by the base board, said casing having an aperture whose axis is spaced from and parallel to the base-board, a spring pressed ball in said casing and projecting partly through said aperture and adapted to be engaged by said strike plate, and a rigid shoulder carried by said casing adapted to engage the door if said strike plate is forced past said ball.

4. In a device of the character described, a pair of cast metal members having flanges at one end and semi-cylindrical sockets at the other end, the axes of said sockets being parallel to said flanges and each socket having at one end a slanting walled openin pins and sockets carried by said members for causing them to register with each other, a rivet holding said members together, with said sockets facing each other to produce a chamber with an opening at one end, and a ball and spring in said chamber, the ball projecting partly through the opening.

In testimony whereof, I hereunto afiix my signature.

WALTER G. SCHERER.
