HENRY H. ASHLOCK, OF KANSAS CITY, MISSOURI.

DOOR AND WINDOW GUARD.

Specification of Letters Patent.

Patented Aug. 22, 1911.

Application filed October 19, 1910. Serial No. 587,988.

To all whom it may concern:

Be it known that I, HENRY H. AsHLocK, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented a new and useful Door and lVindow Guard, of which the following is a specification.

This invention relates to foldable or collapsible guards for use in door or window openings and is more particularly an improvement upon the structure disclosed in Patent No. 895,832, issued to me on August 11th, 1908.

One of the objects of the invention is to rovide a guard of this character which is of compact construction and can be readily set up within a window or door frame so as to occupy the minimum space when not in use but is capable of quick extension across the opening within the frame so as to guard against intrusion by unauthorized persons and prevent exits through the openings when the guards are used in hospitals,

risons or other places of detention.

The device is also especially useful to prevent persons from falling through windows.

A further object is to provide a guard of this character having means for limiting the movement thereof during the extension of the guard, said stop means forming an integral part of the guard.

A still further object is the provision of means for protecting the sill of the frame from wear by the members of the guard during the extension or collapsing of the guard.

WVith these and other objects in view, the invention consists in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a front elevation of the guard, the same being shown secured across a window opening, the wear plate at the bottom of the guard being shown in section. Fig. 2 is an enlarged elevation of the lower end of one of the pickets of the guard and of a link connected thereto, a stop device being shown in contact with the link. Fig. 3 is a section on line A-B of Fig. 2. Fig. a is a front elevation of the locking tongue in engagement with its keeper. Fig. 5 is a side elevation of the parts shown in Fig. 4;. Fig. (3 is a front elevation of the lock-engaging gear and a keeper. Fig. 7 is a section on line C-D of Fig. 6.

Referring to the figures by characters of reference, F designates a window frame and the guard constituting the present invention is adapted to be secured to this frame, preferably adjacent the inner side of the window sashes, although it is to be understood, of course, that, if preferred, the guard may be located outside of the sashes.

The guard includes a series of parallel pickets l of the same size and proportions. one side picket having hinges 2 connected to it and to one of the jambs of the frame F.

The other side picket has a plate 3 riveted or otherwise secured to it and this plate is provided with an angular locking tongue l, preferably extended downwardly, as clearly indicated in Figs. 4: and. 5. Said picket also has another plate '5 riveted or otherwise fastened thereto and formed with an ear 6 extending perpendicularly therefrom and provided with an opening 7. The plate 5 is preferably attached to the picket, adjacent its lower end, while the plate 3 is attached thereto adjacent its upper end.

The various pickets are connected by series of links 8, the links of each series being parallel. As shownin Fig. 1, one series of links is located between one of the side pickets and the next adjoining picket, this last-mentioned picket being connected to a third picket by another series of links. The links of the two series diverge downwardly. This arrangement of links and pickets is followed throughout the extent of the guard, the corresponding links upon the various pickets being extended along zigzag lines when the guard is extended. Moreover, it will be noted that the links of each series are interposed between the two pickets to which they are attached and that the links are of the same width as the pickets. As the result of this construction, when the guard is collapsed or folded, all of the links will be completely housed between the pickets and the corresponding edges of all the pickets will lie in the same plane. The collapsed guard will therefore occupy a space of he same width as a picket and o a depth equal to the combined thicknesses of the pickets and the series of links therethe window.

against the lower one to which the hinges are connected, has,

an out-turned corner 9 constituting a stop or abutment for the adjacent link 8 so that,

when the guard is extended to a predeter'-' mined width, further extension thereof will be prevented by certain of the links moving against the stop projections. Moreover, as the links diverge upwardly from the lower ends of those pickets provided with the stops 9, it will be seen that, when the two end pickets are secured in place, it becomes impossible to raise any one of the intermediate pickets for the reason that such movement would necessitate relative movement of the pickets and links which, however, is prevented by the stops in the paths of the links. It is to be understood that these stops can be very easily formed merely by turning out the corners of the pickets. In actual practice it is designed to extend the guard to the proper length and to then turn the corners of the pickets so that they will bear 7 links, thus preventing further extension of the guard should it be swung out of the window and, also, preventing upward movement of one or more of the pickets when the guard is secured within In order to prevent the lower ends of the pickets from scratching or otherwise mutilating the sill of the frame F, a longitudinally channeled wear plate 10 is secured 7 upon the sill and the lower ends of the pickets are adapted to slide within the channel. This channeled wear plate 10 in turn also serves to prevent the guard from swinging open as long as it is extended.

For the purpose of securing the guard in extended posit-ions across the window or door opening, a keeper of novel form is applied for use in connection with the tongue 4 and the ear 6. This keeper consists of an elongated strip 11 having ears l2 and 13 extending perpendicularly from the ends thereof, the ear 12 beingprovided with an opening for the reception of tongue 4 while the ear 13 has an opening lt adapted to register with the opening 7. The ear 6 is adapted to move intoposition onto the ear '13 and, when thus located, prevents the other ear 12 from moving downwardly off of the tongue 4. It will be apparent, therefore, that by locking the two ears 6 and 13 together by means of a padlock or the like, the guard will be securely fastened both at the top and at the bottom.

What is claimed is: I

1. A window guard including parallel pickets, series of links interposed between the pickets, the links of each series. being parallel and extended between the pickets to which they are pivotally attached, there being laterally bent corner portions at the lower ends of alternate pickets, the lower links of said series diverging upwardly from said lower ends and being limited in their movement relative to the pickets by said corner portions.

- 2. A window guard including parallel pickets, series of links interposed between the pickets, the links of each series being parallel and eachlink being pivotally attached, at both ends, to the pickets between which it is located, and means upon the lower end portions ofalternate pickets and cooperating with the lower links of the series for limiting the extension of the guards and preventing independent longitudinal movement of the picket ends in an upward direction. 7

In testimony that I claim the, foregoing as my own, I have hereto affixed my signature in the presence of two witnesses. I
