Application filed. July 3, 1918.

To all to 7mm it may concern:

Be rt known that we, Trroares VJERTZ ant. new ar on m, -,1- .2 nEuinnLUlL I U131) qhlLYIllL ClolZQllS O1 16 nited States, residing at St. Louis, in the L State of Missouri, have inven ed certain new and useful Improvements in lVinoow-Sash and we do declare the following to description i vention, such as will enable other skilled in the to which it appertains to malre and use the same.

This invention relates to window sash stops, and it relates more specifically to an improved device for preventing relative movement of the upper and lower sash beyond a predetermined distance.

One object of our invention is to pro vide a device of this character in which the stop element is capable of quick and easy removal by a person at the side of the window to which thedevice is attached, so as to allow the window to be opened to its full extent.

Another object of the invention is to provide a device of this character in which the two separable stop elements may be quickly Figure 1 is a fragmental portion of a' window having our improved window stop secured thereon;

Fig. 2 is a vertical sectional view along the line 2-2 in Fig. 1;

Fig. '3 is a horizontal sectional view along the line 3-3 of Fig. 1;

Fig. 4 is a perspective view of the element which is permanently attached to the window sash;

Fig. 5 is a perspective view of the element which is removably secured to the sash through the medium of the element illustrated in 'Fig. a; and

Fig. 6 is a fragmental detail view which shows the inner side of the upper part or": the permanently secured element.

Referring to these drawings in detail in which similar reference characters correspond with similar parts throughout the several views, the upper sash a and the lower Specification of Letters Patent.

Serial No. 243,169.

sash 6, being of ordinary construction, are not described in detail except to mention the ccss c which receives the permanently secured element 7 which is shown separately in Fig. 1. This element 7 comprises a plate which is formed with a pair of parallel flanges 8 which extends at right angles from the intermediate portion 9. The intermertion 9 is provided with screw holes I 10 through which suitable .crews may be engaged with the sash a as shown in Fig. 2. A stud or boss 11 extends from one side of the plate 7, and a stud or spur 12 extends from the opposite side of the plate, the spur 12 being useful as a means for holding the plate 7 in position on the sash while the latter is being scribed for outlining the aperture 0, and also being useful for cooperating with the screws for holding the plate in the recess 0. The plate 7 is formed with a boss 13, a corresponding recess 1 1, and a radially extending aperture or slot 15; said boss and recess being concentric with one another, and one of the apertures 15 being concentric with the boss and aperture and communicating with the latter. A shoulder 16 is formed eccentrically in the recess 14;, and this shoulder forms a stop against which a locking element normally rests. The locking element referred to comprises a shank 17, a shoulder 18, a manipulative element 19, and a wing or lateral extension 20 in the shank 17. The shank 17 extends through a single aperture or bearing 21 which is formed in a normally vertical wing 22 of the stop element shown in Fig. 5, this stop element being formed with a normally horizontal wins 23 and with a base element 2 1 which renders this stop element very strong and rigid. The vertical wing 22 is formed with an aperture 25 which normally receives the stud 11, and this element 22 is also formed with a recess 26 which normally receives the boss 13 and conforms to the shape and size of the latter.

It will be seen that the stop element 22 is merely in the path of the sash b, but not secured to it, and so the stud 11 and boss 13 can quickly and easily be inserted in their respective seats regardless of the relative positions of the complemental sashes. This feature is very important, because when one part is secured to the lower sash and the other part of the upper sash, the shrinking or swelling of the sashes and window frames causes the relative positions of the complemental stop elements to vary and this often renders it impossible to engage the stop elements with one another.

The stud 11 is somewhat longer than the boss 13, measured along their axes and therefore the stud 11 will begin to enter the aperture 25 before the boss 13 enters the recess 26. Therefore, in theevent that the shank 17 of the securing elements is prevented by its lateral extension 20 from entering the aperture 15. it is only necessary to turn the securing element until the lateral extension registers with that of the aperture 15, and the shank 1? will pass freely through the aperture 15 while the boss 13 passes freely into the recess 26. liiioreover, it will be seen that the stud ll supplements the boss 13 in strengthening the connection or engagement of the stop member 22 with the stop member 7.

When the elements of the device are assembled in the normal position shown in Fig. 2, the parallel edges of the wing 22 fit snugly between the flange 8,v the stud 11 t snugly in the aperture the boss i snugly 1n the recess 26, the shoulder 18 fis snu 'ly against the outer surface of the wing o c 22, and the lateral extension 20 fits snugly against the inner surface of the recess l t and against the shoulder 16. Thereforedzhe elements of the device are securely locked together, and it would be impossible to cause any relative vertical movement between the elements shown in Figs. eland 5 unti. the manipulative element 19 is turned to bring the wing 20 in registration with the radial slot 15; but when the manipulative element is thus turned the latter may be employed as a handle for easily withdrawing the stop element from the permanently secured element. When the stop element has thus been removed, the upper and lower sashes may be moved vertically with relation to one another without any interference by this device. However when they are in the as sembled rela 'ion, the wing 23 and brace element 24 extend laterally over the lower sash, and the latter cannot then be moved beyond the predetermined distance which is'determined by the location of the element 17 the upper sash.

Although we have described this embodiment of our invention very specifically, it is not intended to limit this invention to these exact details of construction and arrangement of parts but we are entitled to maize minor changes wit 'n the scope of the in ventive idea disclosed in the foregoing description and following clain rVVhat we claim as our invention is:

A sash stop comprising a vertical plate for attachment to an upper sash, said plate having parallel flanges integral with the .l edges of its outer side, a prong integral with the inner side of said plate near its lower end and adapted to be driven into the sash, ,a lug integral with theouter side of said plate in line with'said prong and adapted to receive blows from a ham ner whereby to drive said prong without inyuu ing the plate or its flanges a boss integral with the outer side of said plate near its upper end, said plate having in its inner side a socket alined with said boss and provided with an internal stop, said boss having a key hole slot opening into said socket, a second vertical plate receivable between said flanges and having an opening and a socket receiving said lug and said boss respectively, a sash stop on the lower end of said. second plate, a pin passing through said second plate for reception in said keyhole slot, a lateral projection on the inner end of said pin for disposition in the first named socket when said pin is turned, and a winged head on the outer end of said pin for contact with the outer side of said second plate.

In testimony whereof we have hereunto set our hands.
