GUSTAVUS IVILLIAM HAAS, OF LOS ANGELES, CALIFORNIA.

PORTABLE DOOR OR SASH LQCK.

SPECIFICATION forming part of Letters Patent No. 565,978, dated August 18, 1896. Application filed November 14, 1895. Serial No. 568,926. (No model.)

' at Los Angeles, in the county of Los Angeles side of the lock.

and State of California, have invented a new and useful Portable Door or Sash Look, of which the following is a specification.

My invention relates to that class of doorsecurers in which two arms or members are.

pivotedtogether by one end and have their other ends provided with points arranged to prevent slippingof the ends, the brace being adapted to be placed in the angle between the door and the floor, or a Window and its casing, and sprunginto position in the manner of a toggle to force the points into the -wood tolthus form a brace which securely holds the door or window from being opened until the brace is removed.

The object of my invention is to produce a device of this class which will fold into very compact shape and will be provided with a locking-bolt which will be at all times chambored withinthe device, so that such device will avoid any objectionable projections and will be extremely convenient for carrying in thepocket or valise.

A further object of my invention is to provide a device of this kind which will be cheap and extremely easy to manufacture, one which will possess the maximum amount of rigidity and strength with a minimum amount of materialand weight;

Myinvention comprises the features of construction and combinations of parts which are hereinafter fully set forth and claimed.

The accompanying drawings illustrate my invention.

Figure l is a perspective View showing my newly-invented door and sash lock in position looking a door. Fig. 2 is a view of the same applied ready for locking two sashes of a window. Dotted lines show the position of parts when forced into the locked position.

Fig. 3 is an elevation of the under or inner Fig. 4 is a longitudinal mid section. Fig. 5 is an enlarged sectional detail of the joint. Figs. 6, 7 and 8 show, the blanks forforming the brace members and thelocking-slide. I

My newly-invented lock comprises a door orwindow securer formed of two arms or members A A, pivoted or hinged together at one end by a pintle or pivot B and provided at their other or free ends with points a a and stop-shoulders a." 0/, arranged to engage with the wood, such members being formed in channelshape or recessed upon one side and adapted to fold together with the recesses opening toward each other. To prevent the two members from being sprung out'of their locked position, I provide a sliding bolt or latch O, which is arranged within the recess of one of the members and is secured thereto by suitable means, such as a screw or stud 0, working in a slot a provided in the base or back of one of the channel members.

D indicates the stop which is formed by the ends of the base or bottom walls of the channel members which engage with each other to prevent the brace from bending in more than one direction.

Preferably the two arms A and A are formed of channel-iron and may be made of sheet metal bybeing forced through a shaper, or may be cast if deemed desirable. Howover, I prefer to make the device of sheet' metal for the reason that by my construction it is very easily manufactured, and sheet metal is not so liable to be broken as is cast metal.

As shown in the drawings, the sheet-metal blanks are each provided at one end with pivot-ears, (shown in Figs. 6 and 7 and these ears project beyond the base or bottom of the channels when the channels are formed. One member, A, is wider than the other member, A, and the ears of the member A are arranged to chamber between the ears of the member A. By this construction the member A is adapted to fold inside of the member A, and greater compactness is secured than is otherwise possible. folded is indicated in dotted lines in Fig. 4. The sliding bolt or latch O is also preferably made of channel-iron, and it and its securingscrew 0 are arranged to slide freely in the member A, so that when the lock is seated in position, as shown in Fig. 1 and in dotted lines in Fig. 2, the latch will drop into place, as in Fig. 4, and extendacross the joint far enough to prevent the joint from bending.

The points a of the lower arm A are preferably made longer than the points a of the Their position when upper arm A, so that when the device is applied to the door the points a will extend through the carpet and seatin the floor. The upper points a are to be made as small as consistent with safety, in order to avoid marring the door or window-sash.

Dotted lines in Figs. 6, 7, and 8 indicate the lines at which the sheet-metal blanks would be bent in order to form the finished arms of the members which form the lock.

To apply the lock to a window, the lower points a will be set upon the top of the lower window-sash and the upper points a will be seated against the inside of the upper sash, the joint being bent at a suitable angle, substantially as shown in Fig. 2. Then pressure is applied to the joint topress it in toward the sash, thus forcing the points a a into the upper and lower sash until the brace is in its fully-extended position, as indicated in dotted lines inFig. 2. As soon as the brace is in its fully-extended position, (shown in Figs. 1 and 4,) the latch C will drop into place by force of gravity and thus prevent the look from again being opened until the latch is first lifted.

To apply the lock to a door, the lower points a are seated in the floor, the upper points a against the door, the brace being bent at a suitable angle. Then pressure can be applied by hand or foot until the brace is fully extended, thus forcing the points into the door and into the floor. Thegreater the angle at which the brace is bent when the points are applied to the door and floor the greater will be the depth to which the points are inserted. Care must be had that the brace is not bent so much as to cause the shoulders a" a' to come into contact with the door and the floor before the brace is fully extended, as this would prevent the look from being effective. It is not necessary that the points fully insert so as to bring the shoulders against the door and floor, for the movement of the door in the act of opening will not be very great before the shoulders will engage the door and floor and thus stop any further movement of the door. Thesame is true in the case of sliding doorsor sash.

The back-stops D of the two arms of the brace are beveled and arranged to allow the "members to throw back beyond a'right line, so that when the brace is in its fully-extended position any strain brought against the brace by attempting to open the door orwindow will be carried by all the parts of the joint, and theact of opening or bending the joint to release the door or window will force the free ends of the arms farther apart than when the brace is in its full locking position, so that the resiliency of the material of the door and floor or of the window-sashes, or other parts into which the points are inserted, tends to hold the braceagainst being bent to release the door or window.

E indicates a rivebsle'eve to hold the rivetbearings from collapsing.

7 To manufacture the lock from sheet metal,

the blanks shown in Figs. 6, 7, and 8 are first cut out by dies and then shaped as indicated by the dotted lines. Then the parts are as sembled and the joint riveted together by the pintle B. The latch C is then secured in place by the screw 0, inserted through the slot a and screwed into the latch-piece C. The points are preferably beveled at their inner faces, as shown in Fig. 8, so as not to mar the wood, but to make a neat and practicably imperceptible imprint.

In the drawings I have shown at the end of each arm two points, the angles of which are acute; but it is to be understood that each arm may have but one point and that the points may be rectangular or of any desired angle or may be rounded, if desired, the purpose being to give a sufficient hold in the wood to retain the brace in position when extended. The shoulders absolutely prevent the arms from'being inserted so deep into the wood 'asto allow the door or window to be opened.

Now, having described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The door or windowsecurer set forth comprising the two members pivoted together at one end and provided at their other ends with the points and the stop-shoulders, such members being opened or recessed upon'one side and adapted to fold together with the re= cesses opening toward each other; and a bolt arranged within the recess of one of the members, secured thereto and adapted to extend across the joint between the two members when such members are open and to lock them in such 'open' position.

2. The door or window securer setforth comprising the two sheet-metal members bent into channel shape'and pivoted together at one end by means of theirside walls, andhaving their other ends provided with the points and the stop-shoulders, one of such members being provided in the base of its channel with a slot; a bolt arranged to slide. withinjthe channel of the members, and a stud provided with a head, passed through. the slot in the slottedmember, fixedto the bolt andadapted to operate the bolt to cause it to extend across the joint between the two members when the members are in their open position.

3. The door or window securer set'forth comprising the sheet-metal members bent into channel shape, one of such members being wider than the other member and each member having its side walls provided at one'end with pivot-ears projecting beyond the base or bottom of the members, the ears of the narrow member being arranged to chamber between the ears of the wider member, each of said members being provided at' its free end with the points and the stopshou1der,and one of said members being provided in its base or back with a slot; a pivot passing through the ears and arranged to pivot the two ears togetherg' the bolt arranged inside the channel of one of the slotted members; and the stud passed through the slot, rigidly secured to the bolt, and arranged to operate the bolt to cause it to extend across the joint between the two members when the members are in their open position. 4

4. The door-securer set forth comprising the two sheet-metal members bent into channel shape, one of such members being wider than the other of said members, and both members having their side walls provided at one end with pivot-ears projecting beyond the base or bottom of the members, the ears of the narrow member being arranged to fit within the ears of the wider member, each member being provided at its free end with the points and the stop-shoulder, and one of such mem- GUSTAVUS WILLIAM HAAS.
