Specification of Letters Patent.

Patented May 2, 1911.

Application filed'March' 29,1910. Serial No. 552,197.

To all whom it may concern:

Be it known that I, JAMEs H. BOBBITT, a citizen of the United States, and a resident of Holstein, in the county of Adams and State of Nebraska, have invented a new and Improved Sash-Fastener, of which the following is a full, clear, and exact description.

My invention relates to sash fasteners, and has for an object to provide a device of the above class to removably engage the sash of a window or the like to hold the same in a locked position. For the purpose mentioned use is made of a rack mounted on a collar in engagement with a spindle, and means engaging the spindle for removably holding the spindle in a locked position to engage the rack with the sash of a window, to hold the same stationary.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which- Figure 1 is a side elevation of a portion of my device showing the rack and springcontrolled collar with the rack in its initial position; Fig. 2 is a similar view but showing the rack in a position whereby it is adapted to engage the sash of a window; Fig. 3 is a front view of my device showing the rack and easing; Fig. 4 is a rear view of the same; Fig. 5 is a sectional plan view disclosing my device in operative position; and Fig. 6 is a sectional side view of the dog and rack for removably locking the spindle, and taken on the line 66 in Fig. 5.

Referring more particularly to the various figures, I employ a casing 1, having a front plate 2 and side plates 3, having mounted thereon a collar 4, comprising a lug member 5 and an arm member 6. Mounted on the arm member 6 is a rack 7 comprising a curved member having a series of serrations 8 thereon, the rack 7 being mounted to slide against a lug 9 secured to the side plates 3. A fiat spring 10 is provided secured to the casing 1 and adapted to en age the lug 5, as will be easily seen by referring to Figs. 1 and 2. The collar 4 is provided with a rectangular hole 11 through which is adapted to pass a spindle 12 having a controlling knob 13 secured thereon, the said spindle being mounted to turn in a window casing 14 of a window 15, having a sash 16, and

seen by referring to Fig. 5. Intermediate the knob 13 and the window casing 14 is a circular casing 17 secured to the window casing 14. Centrally mounted in the casing 17 is a ratchet 18 keyed to the spindle 12, and a dog 19 having a knurled handle 20 is provided in the casing 17 and mounted to engage the ratchet 18, a spring 21 being secured to the casing 17 and engaging a lug 22 on the dog 19, to hold the dog 19 in engagement with the ratchet 18.

To operate my device to removably engage the sash of a window, to hold the same in locked position, the window is raised or lowered to the desired height and the knurled handle 13 is turned to move the collar 4 downward, so that the rack 7 will engage the sash 16, and the dog 19 engaging the ratchet 18 securely holds the spindle 12, so that it can not turn backward and release the sash 16 from the rack 7. Now when it is desired to release the sash, the dog 19 is first drawn out of engagement with the ratchet 18, and then by turning the knob 13 the rack 7 will move upwardly and out of engagement with the sash 16, thereby enabling the window to be moved.

It will be seen that my device can be mounted to act on either the upper or lower sash, or can be so mounted in the window casing that the rack 7 will engage the upper and lower sashes at the same time.

In order to provide a neat appearing de vice, the knob 13 can be artistically decorated in various designs; and the casing 17 can be made to lie flush with the window casing, or as shown in Fig. 5.

It will be understood that although I have shown a particular construction. for the pur pose of describing my invention, I do not limit myself thereto, the scope of my invention being fully defined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A sash fastener comprising a spindle, a collar secured to the spindle, an arm extended from the collar, a rack mounted to swing on the arm, a lug on the said collar, and a spring engaging the said lug, for holdmg said rack in operative position.

2. A sash fastener comprising a spindle, a In testimony whereof I have signed my collar secured to the spindle, an arm exname to this specification in the presence of 10 tended from the collafr, a serrated rack two subscribing witnesses. mounted to depend rom the arm and w 5 adapted to swing thereon, a lug on the said JAMES HOMER BOBBITrl collar, and a flat spring engaging the said \V'itnesses: lug, for holding the said rack in operative JOHN H.
