Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed December 5. 1905- Serial No. 290,340.

To all whom it may concern:

Be it known that I, THEODORE N. JoNEs, a citizen of the United States, residing at Boulder, in the county of Boulder and State of Colorado, have invented certain new and useful improvements in Sash-Holders; 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, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in sash locks, my object being to provide a device adapted to lock either sash against the opening movement and also to hold either sash against further movement when partly open for purposes of ventilation.

My further object is to provide a device of the class stated which shall be simple in construction, economical in cost, reliable, durable and efficient in use, and to these ends the invention consists of the features, arrangements and combinations hereinafter described and claimed, all of which will be fullyunderstood by reference to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure l. is a front view of a window equipped with my improved sash lock. Fig. 2 is a section taken on the line 2-2 Fig. 1 looking in the direction of the arrow, the parts being shown on a largerscale. Fig. 3 is a sectional detail view of the device shown on a still larger scale. Fig. i is a section taken on the line -l-it Fig. 3. Fig. 5 is a detail view of the manipulating key or spindle adapted to adjust the lock from the inside when it is desired to open either sash of the window. Fig. 6 is a detail view of a ventilating plate through which the operating key passes, the said plate being adapted to hold the key in the operative position and prevent it from pulling out. Fig. 7 is a view of the drum housing, looking from the inside of the window frame outwardly.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the window frame, 6 the upper sash, and 7 the lower sash. The window frame is provided on one side adjacent each sash with a mortise or recess 8 in which is located a housing 9 having a drum l0 eccentrically journaled therein. One extrem ity of this drum is provided with a hollow journal l2 whose opening registers with the opening in the adjacent solid portion of the drum through which the key passes. The opposite extremity of the drum is provided with a sleeve 14 which extends through a chamber 15 formed in the drum to make room for a coil spring 16 which is coiled around the sleeve, one extremity 17 being made fast in the solid portion of the drum while the extremity 18 is made fast in the stationary casing or housing 9. The sleeve 14 is provided with a reduced journal 14 which engages an opening in the housing, the shoulder of the sleeve between the journal and the body thereof engaging the housing on the inside whereby the drum is securely held in place. The housing is made in two parts as shown in Fig. 7 so that it may be applied to the drum and then inserted in the recess or mortise 8 formed in the frame adjacent the sash run-way as heretofore explained. The housing members are secured in place by suitable fastening devices as screws 19 (see Fig. l).

The window frame is bored from the outside to form an opening registering with the opening of the drum and in this bore is inserted the key 13 whose portion engaging the drum is angular or polygonal in cross section to engage a counterpart opening of the drum whereby as the key is turned a corresponding movement is imparted to the drum. To the outer extremity of the key 13 is applied a milled head 20. As shown in the drawing this head is provided with a polygonal or square opening to engage the portion 13 of the key of counterpart'shape, the head being locked in place by means of a screw 21 threaded in the end of the key. In order to prevent the withdra 'al of the key, the latter is provided with a circumferential groove 22 in a portion thereof which protrudes from the window frame when the key is in place. This circumferential recess is engaged by plate members 23 secured to the frame on opposite sides of the key, the inner edges of the plates engaging the groove of the key thus permitting freedom of rotation but preventing longitudinal or endwise movement. The plate members .3 are made last to the frame by means of fastening screws 24: insorted in suitable openings.

From the foregoing description the use and operation of my improved device will be readily understood. As shown in Fig. l of the drawing, two of the devices are employed for each window, that is to say one for the upper sash and one for the lower sash. Each device is so located and arranged, that if an attempt is made to open the window or to raise the lower sash or lower the upper sash, the sash acts to actuate the cccentrically mounted drum to cause the latter to engage the sash more tightly, whereby the sash is prevented from moving in the opening direction. Now if it is desired to open either sash, it is only necessary to turn the key 13, in such a manner as to turn the drum in a direction opposite that in which it is actuated by the sash when an attempt is made to open the window in opposition to the lock. This movement of the key throws the eccentric cam out of engagement with the sash and allows the operator to move the sash in a direction to open the window. When the sash is opened or adjusted as desired, and the key released whereby the eccentrically mounted drum is allowed to return to engagement jwith the sash, the latter is locked against theflfurther opening movement. By virtue of this Having thus described my invention, What I claim is:

1. In a sash lock, the combination with a suitable casing or housing, a drum eccentrically mounted therein and re cessed at one extremity, the recessed portion of the drum being provided with a sleeve which the recess surrounds, the free extremity of the sleeve forming one of the drum journals, a coil spring surrounding the sleeve Within the recess or cavity of the drum, one extremity of the spring being made fast to the drum and the other extremity connected with the housing.

2. In a sash lock, the combination with a housing, a drum eccentrically mounted in the housing and provided with a recess at one extremity, the said recess surrounding one of its journals, :1 torsional spring located in the recess, the spring being connected with the drum at one ex tremity and with the housing at the opposite extremity, the drum being provided with an opening in the line of its axis, the said opening being angular in cross section, and a key shaped to fit the said drum and adapted to turn the in the frame, and a key passing through the bore of the frame and entering the opening of the drum, the drumopening and the key being shaped to cause the two parts to turn in unison, the key being accessible from the outside of the casing, and suitable means applied to the casing and engaging the key to hold the latter in place without interfering with its rotary action.

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

THEODORE N. JONES.
