Sash-lock.

Application filed February 3, 1911. Serial No. 606,409.

To all whom it may concern:

Be it known that I, Charles Hudson Snider, a citizen of the United States, and resident of Conway, county of Horry, and State of South Carolina, have invented certain new and useful Improvements in SashLocks, of which the following is a specification.

This invention relates to improvements, in window buttons and has for its object the provision of a window button adapted to lock the lower sash against upward movement and to force the meeting rails into tight engagement when the sashes are in their normal positions so as to prevent rattling.

The above and other objects will be better understood from the'following description, taken in connection with the accompanying drawings, in which—

Figure 1 is a cross sectional detail of the upper and lower sashes showing my device in side elevation and applied thereto; Fig. 2 is a similar view showing the device in vertical section; Fig. 3 is a view similar to Fig. 1, but showing the latch disengaged from the keeper and held elevated; and Fig. 4 is a perspective view of the parts detached.

The meeting rails are designated by the numerals 5 and 6, and the window panes by the numerals 7 and 8. The keeper is preferably secured to the upper surface of the meeting rail 5 of the lower sash and comprises a horizontal portion 9 corresponding approximately to the width of the rail 5, and a vertical portion 10 somewhat less in width than the horizontal portion 9. The vertical portion 10 is arranged at that side of the horizontal portion 9 which is nearest to the rail 6, and at its upper end is provided with a bead or shoulder 11. The bead or shoulder 11 overhangs the horizontal portion 9,' as shown in the drawings. The horizontal portion 9 is provided with openings 12 for the reception of screws or other fastening means to secure it to the rail 5.

The support for the latch comprises a horizontal portion 13 somewhat less in width than the width of the meeting rail 6 of the upper sash, portion 13 having openings 14 for the reception of screws or other fastening means for securing it to the rail 6.

When the support for the latch is secured, 55 as shown in Figs. 1 to 3 inclusive, the inner side or that adjacent to the keeper, will be coincident with the inner side of the rail 6 or substantially so, but there will be a space between the outer side and the pane 60 7. Rising from the outer side of the portion 13 is a vertical wall or stop 15, the upper side of which is enlarged and rounded as shown at 16, such enlarged round portion overhanging the portion 13. Formed with 65 the portions 13 and 15, are a pair of spaced lugs 17 and 18, the space between said lugs alining with an opening 19 formed in the vertical portion 15.

The latch is made up of two sections 70 designated by the numerals 20 and 21. One end portion of the section 21 is arranged between the lugs 17 and 18, and is provided ' with an opening 22 to aline with openings 23 formed in the lugs, these alining open- 75 ings receive the pivot pin 24. The opening 22 is so positioned with respect to the adjacent end of the section 21 that the said adjacent end will not bind on the portion 13 when the latch is being moved from a 80 horizontal to a vertical position, and vice versa; in fact, a recess 25 is formed in the portion 13 and between the lugs 17 and 18, and this recess communicates with the opening 19, which latter is provided for the pur- 85 pose of receiving the pivoted end portion of the section 21 when the latter swings outwardly. The opposite or outer end portion of the section 21 is provided with a tongue 26 and shoulders 27 and 28. The shoulders 90 27 and 28 at one end curve upwardly as shown at 29 in Figs. 1, 3, and 4, such curvature being located on the side adjacent to the pane 7 when the section 21 is in raised position as shown in Fig. 3. The section 95 20 is recessed at one end, as shown in Fig. 4, to receive the tongue 26, and the extremities of the section 20 on either side of the said recess are shaped to conform to the contour of the shoulders 29 upon which they 100

1,007,398 bear. With this construction, it will be manifest that a knife blade joint is produced whereby movement of the section 20 with respect to the section 21, will be lim5 ited in one direction. The tongue 26 is provided with an opening, not shown, and this opening alines with similar openings formed in the sides of the recess, and arranged in the said openings is a pivot pin 30. The 10 free end portion of the section 20 is slightly offset and on its inner face is provided with a curved bill 31. The curvature of the inner surface of the bill conforms to the Curvature of the bead 11 of the keeper and the ex15 tremity of the bill is rounded off as shown at 32, such rounded portion being received by a groove 33 formed in the inner surface of the vertical portion 10 of the keeper, and directly below the bead thereof.

The sections 20 and 21 of the latch are yieldingly held in alinement by means of a leaf spring 34, one end portion of which is secured to the outer side of the section 21, and the free end portion of which bears on 25 the corresponding side of the section 20.

When the latch is arranged on the support and out of engagement with the keeper, as shown in Fig. 3, the said latch is held elevated by means of a spring. This spring, as 30 shown in detail in Fig. 5, comprises a horizontal middle portion 35, opposite side portions 36 and 37, coils 38, and bearing portions 39. The distance between the coils 38 is a trifle greater than the width of the 35 portion 21 so that the latter may be inserted therethrough when assembling the parts, and when so inserted the opening 22 is brought into aliiiement with the coils 38, after which the pivot pin 24 is inserted 40 through the parts as before described. The middle portion 35 bears on the outer end portion of the section 21 and the bearing portions, 39, bear on the upper surface of the portion 13 of the support. The side 45 portions 36 and 37 are normally at substantially right angles to the bearing portions 39, so that when the latch is disengaged from the keeper, the horizontal portion by tending to move outwardly will force the 50 latch upwardly until the same abuts against the rounded portion 16, as shown in Fig. 3. When the parts are so. positioned, the extremity of the bill will be out of vertical alinement with the bead of the keeper and 55 the rail 5 so as to permit upward sliding movement of the lower sash.

It will be seen now by reference to Fig. 1, that the distance- between the extremity of the bill and the pivotal point of the latch, 60 when the meeting rails are in horizontal alinement, is somewhat less than the distance between the said pivotal point and the inner side of the bead 11, so that when the latch is moved into engagement with the keeper, the bill will first bind on the bead 65 as shown in Fig. 1. By a continued downward pressure, however, the spring 34 will be flexed as the section 21 moves downwardly and outwardly, and its outer end. moves nearer to the keeper. As the outer 70 end of the section 21 moves toward the keeper, the bill 32 will finally move over the bead 11 and into the socket 33 whereupon the spring 34 will assume its normal position and force the bill into the groove. It 75 will be seen that during this movement, of the bill, the meeting rails will be moved relatively to each other and into tight engagement, whereby rattling will be prevented. In order to disengage the latch from the 80 keeper, the free end portion of the section 20 is moved upwardly and outwardly either by hand or by a suitable tool, until the bill clears the bead, whereupon the spring will move the latch to the position shown in 85 Fig. 3.
