WINDOW GUARD.

Application filed September 24, 1925.

My invention relates to improvements in window guards.

An object of the present invention resides in the provision of a window guard I mounted for vertical sliding movement with relation to the window pane and adapted to be automaticall looked in its lowermost active position, y a novel construction of a lock mechanism carried by the guard, thereby preventing the contents of the window from being stolen should the Window pane be broken by anyone with this object in view.

In carrying out the invention I contemplate the use of a manually controlled element for both raising and lowering the guard, and connect said element with the locking arm of the lock mechanism, whereby said arm is moved to a retracted or inactive position to release the guard, simultaneously with the use of the control element for elevating the guard.

Another important object of the invention resides in the fact thatthe lock casing is carried. by the guard and designed to serve in the capacity of a sliding bearing to assist in supporting the guard for vertical adjustment on suitable guides.

Fig. 1 is a fragmentary portion of the guard showing one side thereof, with the lock mechanism;

Fig. 2 is the same of a modified form, the lower section of the guard being shown in lowered and the upper section in an intermediate position.

Referring to said drawings, and particularly to Fig. 1 which illustrates a frame formed of a series of closely arranged, vertically disposed steel or iron rods a, the upper and lower ends of which, respectively, are suitably secured in the longitudinally disposed bars 6, 0, which extend widthwise of the window, and, with the bars a and end side members 1 constitute the frame which forms the guard, whichis slidably mounted on the vertically disposed posts 2. Each side member 1 has suitably secured thereto, at a point adjacent the lower end of the guard, an arm 3, the outer ends of which terminate in eyes d, which form sliding bearings on the vertically disposed cylindrical rods.

or posts 2, on which the guard is adapted to be elevated and lowered by a single manually controlled element. This element is preferably in the nature of a cable or rope 4:

the outer end of which is connected to the Serial No. 58,317.

upper end of the lock bar 5, while the free end of said rope passes over the block 6, which is supported in the ceiling of the window. The frame is adapted to be held in locked position when the same is lowered over the lower section of the window pane by means of the lock mechanism secured to each end of the frame at the extreme upper side thereof. The said lock mechanism comprises a casting 7, which is integral with the side member 1, or is secured to the said side member. There is one of these castings ar-- ranged on each side of the guard, and it will be noted that each casting is formed with a cylindrical portion slidably mounted on the adjacent rod 2, so that the casting not only houses the lock mechanism, but is also used in the capacity of a sliding bearing, cooperating with the eye cZ carried by the arm 3 for supporting the guard for vertical sliding movement. In the interior of said casting a lock arm 5, is swingingly or pivotally mounted on the rod 6, which is secured in the walls of said casting, the lower end of said lock arm terminating in a hooked portion 7, which, is adapted to engage in acorrespondingly shaped notch h in the outer wall of the casting and also engage the adjacent post to hold the guard locked in its lowermost active position. The said lock arm is held in engagement in said notch by means of the blade spring 8, the free end of which exerts pressure upon the rear side of said lock arm for the purpose of holding the same in engagement with said notch. The upper end of said lock arm is attached to a rope or other flexible connection 4, by pulling which upwardly throws the lower end of the lock arm out of engagement with the notch and permits the lock arm to pass through the slot k in the casting and enables the guard to be elevated. Manifestly the lock arm is moved. to its inactive position to release the guard, and the latter elevated by one and the same element, namely the cable or rope 4, and these two operations take place practically at the same time by a continued pull on the cable.

In order to lessen the concussion of the frame when the same is lowered, a bumper 9, formed of rubber, is mounted on the support 10, for the purpose of absorbing the shock of the descending frame.

In Fig. 2, I show a modified form of my device in which the guard comprises two units, one of which comprises the side members 11,-t'owh1ch theends of the cross bars 12 andldare securely fastened; rods 14; be-

ing slidably positioned in the bar 12; andthebar 13, similarlypositioned on the, vertical rods 15, 15. The rods 14, near the top have fastened thereto horizontally disposed bar 16, and near the bottom a bar 1", the said rods 14 being slidably positioned inbars'lZ, and the rods 15 being slidably mounted on the bar 17 whereby the two units, one comprising the bars 12' and 13, and the side members 11, the other the bin-s16 and 17, and the rods 1 1, may be slidably collapsed or telescoped: one against the other when the guard as an entirety elevated by pull ing upon the flexible member or ropewhcreby thehorizontal bars liland 16are brought together and the guard, as an entirety is shortened when in an elevated position.

To elevate the structure when the lock arm 18 is disengaged from the notch 19 in the side of the casting 20, by pulling on the rope 21, the guard is caused to move upward on the bearings 22, encircling the posts 23, the upward'movementof the side members and the bars 12, 13, ultimately bringing. the bar 12 closely against the barlti, and changing. the

positions of the bars 13, 17, which have re-.

spectively movedupward on therrods and 15. The unit comprising. the bars 16. and 17, and the rods 1-1, are adapted when the structure is in lowered operativev position to descend or drop by gravity so that the.

lower end of the rods 14s restuponthe upper side of the bar 13. It is obvious that an a-uton'latic lock mechanism may be provided for the purpose of preventing the upper unit com rising the'bars 16. 17 and rods'li from being elevated, although evenif the unit was elevated the lower section of the guard is locked when in lowered position, and the rods 15 are sufficiently close to prevent" the hand being inserted therebetween.

Having. described my invention what I claim and desire to secure by Letters Patent-is:

1. In combination, spaced supports, a window guard positioned between said supports, bearings carried by said guard adjacent the lower ends thereof and surrounding said supports, hollow castings carried by the guard adjacent the upper, end thereof, and constituting bearings surroundingsaid supports, whereby the guard is mounted for vertical sliding movements, locking'means aranged within said castings and cooperating with the adjacent supports for automatically locking the guard in its lowermost position, and means for elevating said guard when released from said supports.

52. In combination, a window guard mounted for vertical sliding movement, spaced stationary posts supporting said guard, hollow castings carried by the guard and formed to provide bearings slidable on said posts, a cable suspended from an overhead support for raising and lowering said guard, a spring pressed pivoted locking'arm arranged in each castingand normally proj ected therefrom to engage the adjacent post and automatically lock the guard in its lowermost position, and said cable being con nected with said arm, whereby the latter is rendered inactive and the guard elevated incident to a pull on said cable.

In testimony whereof, I have hereunto signed my name.

MORRIS GOLDSTEIN.
