BARNT M. WHITING, OF SAN FRANCISCO, CALIFORNIA.

Letters Patent No. 113,123, dated March 28, 1871.

IMPRovlalllllzrlTl IN sAs'H-HOLDERS.

The Schedule referred to in these Letters Patent and making part of vthe lame.

To all whom it may concern Be it known that I, BARRET M. WRITING, of city and county of San Francisco, State of California, have invented an Improved Sash-Lock and Fastener; and I do hereby declare the following description and accompanying drawing are sufficient to enable any person skilled in the art or science to jwhich it most nearly appertains to make and use my said invention or improvements without further invention or experiment.

The object of my ihvention is au improvement on that class of sash-fasteners which locks and secures the sash in any desired position. y

` In order to more fully illustrate my invention reference is had to the accompanying drawing forming a part of this specification, in vwhich l A represents a window-frame having the upper sash B and lower sash C.

The shaft d is secured vertically in boxes to the side piece of the lower sash-frame, and has xed horizontally at its upper end a toothed segment, e.

The shaft d is simply a small metallic rod or wire, and can extend down as far as desired. l

A thumb-plate or lever, f, on the lower end of the shaft d, within easy reach of a person standing on the floor when the lower sash is raised, serves to rotate the shaft in order to lock and unlock the sash.

Upon the top of the lower sash is a segmental wheel, g, a portion of which is provided with cogs, while the other portion is plain and serves as a'lock.

This wheel is secured horizontally to the upper face of thetop rail of the sash-frame, so that its toot-hed portion will be engaged by the toothed segment e, which is on the upper end of the shaft d, by which if can be partially rotated each way.

A rack-bar, h, is secured'to the side rail of the upper sash-frame, so that, when the wheel g is rotated in one direction, the plain edge will enter between any two of the teeth on the rack, and thus hold the sash in position.

This much of mydeviee, formost windows,y will be all that is necessary to form a perfect and securelock. Where the upper sash slides upand down. in the frame a rackfbar, h', is secured to the casing alongside of the lower sash, between the teeth of which a lug, t', on the shaft d, below the thumb-plate f, enters when the shaft is rotated, so vas to lock the upper sash, thus allowing'either sash to be locked independently of'the other.

In place of the segmental wheel g a plate, j, shown at fig. 3, might be employed, in which case the rackbar h should be secured to the casing above the lower sash, so that, when the plate j is thrown in one direction, one of its ends will engage in the rack h, while its-opposite end engages with theA rack h,thus locking the sashes.

By the use of this sash-fastener either the upper or lower sash can be locked at any desired position, and when thus fastened they'will be securely locked, so as to successfully resist any attempt to change their position Without first freeing their fastenings.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent, is-

The vertical shaft d with its toothed segment e, and

thnmb-1ever or plate j, the lug 'i in combination with y the partially-toothed locking-wheel g, and rack-'bars h and h', substantially' as and for the purpose above described.
