SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 415,882, dated November 26, 1889.

' Application filed March 18, 1889. Serial No. 303,694. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE V. POWELL, a citizen of the United States, residing at Moriah, in the county of Essex and State of New York, have invented certain new and useful Improvements in VVindow-Sash Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to improvements in window-sash fasteners; and it has for its object to provide a sash-fastener which will be effective in operation and which will serve the additional function of a weatherstrip.

Theinvention will be fully understoodfrom the following description and claims, when taken in connection with the annexed drawings, in which-- Figure l is a face view of a window with my improvements applied. Fig. 2 is a vertical sectional view taken in the plane indicated by the dotted lines a: 00 of Fig. 1. Fig: 3 is a plan view of the top horizontal lockstrip. Fig. 4 is a cross-sectional view of the same, taken on the line y 3 thereof. Fig. 5 is a perspective view of one of the metallic wear-strips as employed in the slots of the weather-strips. Fig. (3 is a sectional detail view taken on the line .2 z of Fig. 2; and Fig. 7 is a sectional detail view of the upper portion, looking in a direct-ion opposite to that of Fig. 2.

Heretofore sash-fasteners have been employed in which oblique or incline slots are formed, so that they may be moved to and from the sash, and such fasteners have been made to serve as weather-strips.

My improvements differ essentially from these, in that the strips have two opposing inclined surfaces and the movable or sliding parts are so arranged that one of them will tend to lock or impinge upon the lower sash when moved in a direction opposite to the locking action of the opposite strip; consequently, when the strips are moved so as to hold the sash in the position desired, any effort to move the sash either up or down will be forcibly opposed by a double lock, and one which will act automatically or by the movements of the sash itself.

Referring by letter to the accompanying drawings, A indicates a win (low-casing, which may be of any ordinary or approved construction. This casing is provided in its sill and at the base of the vertical rails with recesses a, to receive the lower end of the lockstrips, as will be presently explained.

B and 0 indicate window-sashes which are placed in the casing, as shown.

D indicates a short strip which constitutes the upper portion of the Weather-strip and sash-fastener. I employ one of these strips on each side of the windowecasing, and rigidly secure them to the upper portion thereof, as shown. These strips D have their inner lon' gitudinal sides inclined, and the incline of one is just the reverse of that of the otherthat is to say, the incline of the right-hand strip D is on the outer side and from above downwardly and inwardly, while the incline of the left-hand strip is on the inner side and from above downwardly and outwardly.

E indicates the movable or sliding strips, there being also one on each side of the easing, and serve respectively, in conjunction with the rigid strips, to form weatherstrips and sash-fasteners. The right strip E has its upper inner side inclined to conform to and engage the inclined face of the upper rigid strip D. This strip E is provided with a suitable number of oblique slots 1), which are lined with metallic wear-plates, as will be presently explained, and said slotsIare arranged' at an angle to the slots in the lefthand strip E. The left-hand strip E has its outer upper side inclined, as described, to conform to the inclined face of the upper rigid strip D, and is also provided with the oblique slots.

F indicates screws or the like, which serve to hold the sliding strips and guide the same in position. These screws pass through the slots and take into the side rails of the casing.

By the construction described it will be readily apparent that when the sliding strips have been set up against the sashes anytendency to move the latter either up or down will merely serve to apply the fastenings more forcibly thereon. This is due to the fact that the inclined faces are reversed, and that they are forced against the sashes by being moved in opposite direhtions.

F indicates a sliding strip arranged on the inner side at the top of the casing. This strip is also provided with oblique slots, so that it may be crowded against the top rail of the upper sash and co-operate with the other members in forming a weather-strip, as well as a lock or fastening.

G indicates the metallic wear-plates for the slots of the movable bars or strips. The form of these plates is better shown in Fig. 5 of the drawings. These plates are shaped from sheet metal by cutting an oblique slit in the right direction and continuing slits at opposite ends and parallel thereto, so as to form a lip d. These. plates are secured around the inner sides of the slot-s in the strips with the tongue orlip d therein, and on the side which the greatest friction is brought by operation.

These plates prolong the usefulness of the thereof, one of which strips has its inner 1ongitudinal side inclined and the opposite strip its outer longitudinal side inclined, and the sliding strips having their upper portions inclined to conform to the inclines on the fixed strip, substantially as specified.

2. The combination, with a window-casing having its sill recessed, as described, of the obliquely-slotted sliding strips, having their upper longitudinal edges inclined and their lower ends adapted to enter the recesses of the sill, and the-upper strips secured to the inner walls of the casing and beveled so as to engage the beveled edges of the sliding strips,

and the horizontal sliding strip secured to the upper inner side of the casing, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE W. POWELL. Witnesses:

W. T. SHERMAN, E. W. BURHAUS.
