\QQI' uni" 'ATEN T EDWARD HEID, OF INDIANAPOLIS, INDIANA.
AUTOMATIC SASH-LOCK.
Specification of Letters Patent.
Patented May 25, 1909.
Application filed February 25, 1909. Serial No. 479,996.
To allwhom it may concern:
Be it known that I, EDWARD HEID, a citi-.
zen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Automatic Sash-Locks;
and I do declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to locks or fasteners for vertically sliding window sashes that are used in pairs, comprising each a lower-sash and an upper sash, either balanced or without balance weights, the invention having reference particularly to devices whereby the sashes may be prevented from being opened, or whereby when either sash is opened purposely to a limited extent it maybe locked or latched to prevent further movement of the sash in its frame by persons outside of the building.
An object of the invention is to provide reliable sash locks especially adapted to permit the upper sash to be lowered for ventilating 1purposes and securely locked for limiting t a further object being to provide a sash lock that will automatically lock both sashes in closed position when either or both sashes have been closed after having been opened to a limited extent for ventilating purposes, it being an object of'the invention to provide locks whereby the ventilating openings may be limited in extent so that prowlers or sneak thieves can not enter the restricted openings.
A still further object is to provide an automat c sash lock that will be adapted to be applied readily to window sashes that are already in use, and be strong anddiirable.
The invention consists in a ratchet-toothed bar adapted to be attached to an upper sash, and a novel spring pressed catch adapted to be attached to the top of the lower sash to cooperate with the latch bar, the invention consisting further in the parts and combinations and arrangements of (parts, as hereinafter )articularly describe and afterward definer in the accom anying claim.
Referring to the rawings Figure 1 is a fragmentary elevation of the inner side of a Wall and a window therein provided with the improved sash locks; Fig. 2, a vertical sectional view-on the line A A in Fig. 1; Fig. 3,
1e amount of opening above the sash,
a fragmentary elevation reproducing a pori tion of Fig. 1 on an enlarged scale; Fig. 4, a fragmentary sectional View taken near the line B Bin Fig. 3 Fig. 5, a fragmentary vertical section ap roximately at the plane of the line C C in ig. 4; Fig. 6, a perspective 5 view of the. improved latch; Fig. 7, a perspective view of the siipporting base of the latch; and Fig. 8, a front or plan view of the latch bar.
Similar reference characters in the drawings indicate like parts or features of construction referred to herein.
In the drawings, 0 indicates the sill, b and c the upright side parts and d the top part of a window frame, 6 indicating the upper sash, and f the lower sash of the window mounted in the usual manner, so as to slide vertically. The invention comprises two latch bars 9 and g of identical construction which are secured to the inner side of the lower portion of the up er sash e and extend substantially from the ower end of the sash upward along the side arts of the sash to any desired extent, eac' latch bar being preferably of such length that it will serve as an indicator as to the extent that the upper sash should be lowered or the lower sash raised safely in through the opening. Each latch bar has a pluralit Y of inclined angular faces h and abrupt shoulders & constituting ratchetteeth, and the ends of.the bar have apertures j and j therein to receive screws 70, whereb the bars are secured rigidly to the sash, t 1e bars extending a short distance behind the upper portion of the lower sash. A pair of latches l' and l constituting ratchet dogs are mounted on the top of the lower sash and are s ring pressed into engagement with the ratc et-teeth of the latch bars so that they will engage the shoulders 01 and normally revent the upper sash from belng lowered or raising of the lower sash, each latch having an operating lever m formed thereon. The body portion n of the latch is relatively thick and strong and has an abut ment 0 formed at the under side thereof so as to be practically at the lower end of the latch, a portion of the body of the latch being formed as a relatively thin wing p inwhlch is a ivot hole (1. Each latch has a supporting ase plate 1* on which two wings s and s are formed that have pivot holes t and t therein respectively, the plate having apertures u and u therein to receive securing order to prevent admission of a person Cir , as to carry -under side of the lever n adjacent to .the
wing 19, the end of the arm y" having an angular hook-like projection 11/ that enters a socket z in the under side of the lever at the end of the groove therein so that the arm y is prevented from dislodgment in operation. By reference to Fig. 4 it will be seen that.
the abutment 0 is normally spring pressed against the top of the base plate r when the latch dog Z is engaging a shoulder i so that the thrust is sustained without straining the pivot of the latch, and this also prevents the atch from engaging and marring thesurface of the upper sash when the sash is moved so the latch bar down out of reach of the latch. 1
In practical use when both sashes are closed the latches l and Z will engage the ratchet-teeth of the lock bars Z and l at the lower ends of the latch bars and normally revent movement of either one of the sashes. 11 order to either lower the upper sash or raise the lower sash the levers m of the latches must be depressed so as to disconnect the latches or dogs from the ratchet-teeth, and then either sash may be moved, and inasmuch as the latch bars may be seen above the lower sash it is clear that either sash may be moved until the dogs engage the uppermost shoulders 11 on the latch bars which will indicate that the sash has been except by operating the latch levers.
moved within the predetermined limit. If occasion requires it, however, the sashes may be moved to a reater extent, as will be apparent, and when the open sash is being closed it will be seen that the latches will be s ring pressed against the inclined faces h of tlie ratchet-teeth until the sash is stopped, either in closed osition'or artly closed,and will automatica y engage the shoulders "i and prevent either sash from again being 0 enefi be c ear, therefore,'when a room has been ventilated and the opensash hasbeen closed it will become automatically locked sov that itcan not be opened from the outside, and
therefore a window can not be carelessly left unlocked afterhaving been closed or when opened to the desired extent for ventilating purposes.
Having thus described the invention, what is claimed as new, is
A sash lock comprising a base plate having two ears thereon, a latch dog having an operating lever and also an abutment thereon and arranged between the two. ears, the body part of the dog having a relatively thin wing, a pivot-pin connecting the wing to the two ears, a s ring'on the pivot-pin between an ear and t e wing and having an arm engaging the base plate and also an arm engaging the lever, said spring normally holding the abutinent in contact with the base plate, and a ratchet-toothed latch-bar to be engaged by the latch dog.
In testimony whereof, I affix my signature in, presence of two witnesses. I
