CHARLES SOMMER, OF CHICAGO, ILLINOIS wlNDow LIFTINGAND oLoslNe.- DEVICE.
Specication of Letters Patent.
App'iimion filed February 5,1906. Serial No. 299,382.
the city of Chicago, in the county of Cook and State of Illinois, have inventeda new and Improved Window Lifting and Closing Device, of which the following is a full, clear,
and 'accurate descri tion.
This invention re ates to improvements in window-sash lifting and closing devices; and it is the object of same to. providea mechanical contrivance by .means of which .this can be readily accomplished by any person and in the case of windows access to which is obstructed by furniture and other obstructions. I attain this object by means of a spring-.ac-
tuated contrivance in-which the movement of the spring-housing is controlled by a pawll arranged horizontally above the periphery of the former engaging with the inclined ratchet-teeth cut into the top of the open housingand being provided with a lever forming a counterweight,xwhereby engagement between the inclined teeth and the pawl is maintained. This lever is used at the.

Figure 1 is a front view of the device ernbodying my invention, partly in section and showing the position of the spring-barrels within the window-frame and their connection with a corresponding rack. Fig. 2 is a transverse section through the casing containing the spring-actuated barrels. Fig. 3 is a sectional plan view showing the relative position of the window-sashes with their respective racks and the corresponding connect1on with the spring-barrels. Fig. 4 is a full front view of the complete window and frame.
Referring to the drawings, 1 designates a casing designed to be seated in a recess of al Window-frame. This casing is provided with two compartments, each containin a springbarrel 2 and 3. S ring-barrel 2 1s located with relation to the ower and 3 with relation Y 3 are mounted to-rotate.
.engaging with a pawl, thereby to the upper sash.l Both sashes are actuate by their respective spring-barrel in. the direction as indicated by arrows. Casing 1 is secured within window-frame 4 by wood-screws 5. Extended transversely through the cas'- ratented July 31,1906'.
ing and held from rotary motion thereto are shafts 6 and 7, on which spring-barrels Zand Arranged within spring-barrels 2 and 3 are coiled springs 8 and 9. Oneend of each spring is attached to' the journal of the spring-barrel, while the `other is fastened to pins 10 and 11, each pin being secured in bosses 12 and 13 of the casing by means of a'screw-thread, as shown. On the periphery of each barrel are gear-l teeth 14, designed to en age with a corresponding rack 15, seated in a vertical recess formed in the side rail of the sash, as clearly indicated in Fig. 1.
Springs 8 and 9 are housed within vthe spring-barrel by means of a housing 16, the crown of which is provided with teeth having an inclined plane designed for the purpose of orming a ratchet. vPawls 17 and 18 are pivoted inlugs 19 and 20, forming a part of casing 1, and
ypins 21 and 22.
placed into the recesses of the window-frame.y
The device is laced in both of the yer-tical members of t e windowfframe midway between top and bottom, operating the upper as well as the lower sash from its central posi- IOO tion and properly counterbalancing the weight of each sash, as shown in Fig. 4. The device shown in the left-hand vertical member of the window-frame may be minus the pawls,
as shown. For example, if the lower sash is to be raised awl 22 is disenga ed by pressing lever 24 ownward within sot 25, Fig. 4. Spring 9 will then rotate s ring-barrel 3 in the direction indicated. T e latters teeth will engage with those of the corresponding rack 15, and the sash moves u ward until the desired width of opening has een obtained,
whereuponpawl 22 is released. Immediately I its own weight forces it into engagement with the ratchet and the movement of the sash is at once arrested, as will be obvious. When the upper window is openedie., when the upper sash is forced downwardspring 8 is wound around the journal part of barrel 2, the spring is set at tension, andpawl 2l secures it in this position until said pawl is disengaged by pressing lever 23 downward within slot 26, which sets the device in action in the same way as explained above.
It will be seen that each sash may be stopped at any desired point within the range of its possible movement by a very simple and effective mechanism.
Having thus fully described the novel features of my invention, I claim as new and desire to secure by Letters-Patent* A window lifting and closing device, comprising a casing arranged in a window-frame,
tain the en agement between t e pawl and the said inc ined teeth, a rack secured to the vertical member ofthe window-sash and gear connection between the s ring-housing and the said window-sash, su stantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
