, IMPROVED WINDOW-SHADE RACK.

`'.'lhe Schedule referred to: these Lettera Patent and making part of the samey `-To all Chant *it-'lacy concern.- I. l

BeV it known -that LfJosnUA IUsur, of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Window-shade Racks; and I do hereby I declare that the following is a full,clear, and exact description` thereofifreterence' being had to the ac-Y companying drawings, and to the letters of reference marked thereon, whichgform a part of this specifi- I cation.

y, `Ihe object of my invention is to provide a window'- y shade rack which shall be neat, cheap, and eficient; `whicn maybe, it desired, entirely and `readily cast in -metal; the separate partsof which maybe easily put togethenaud when together,not apt to become disaconnected, or to get out of order.

. I Myshaderackis composedof three distinct-parts',

representedin the annexed drawings in figs. 1, 2, and 3. y Figure!!! represents jtheseparts put together, and the device as it appears iuactual use or operation.

Figure 1 is a vertical longitudinal section, through the middle, of `a. slotted metal guide, (which may beof any suitable ornamental form,) showing one-half of the `inner sideof the same, the `remaining half being its exact obverse. `',Ihe sides of this guide become morev elevated and broadened into a head, A, which is provided `with recesses, x, upon its inner slotted Iside, open- -ing out and downward at one extremity, closed and y rounded at the upperend.`

is a projection, extending beyond the lower face ofthe guide, the object of which is hereafter explained.l

It is arcountersunk screw-hole. i v `Figure 2 `representsa pawl, whose head is liattened or depressed at a certain point, as at l, and whichis provided with a tootl1,-t,iand projecting journals J J, the` latter of suchiform and 'dimensions as'to play loosely in the recess 1x', and its obverse. The mainl portion of the pawl extends back, and is formed into some ornamental shape, such as a leaf', as appears in Figure 3 is a toothed orratcheted rack, of any desired length, and constructed to Aslide freely into thcl `g'uide,ig. 1. One'extremity,b, of this rack, bends upythen'brauches out, and bends slightly inward, on each side; the other extremity ends in a lug, y, projecting `abovethe teeth ofthe rack.v Figure 4 shows my invention as it appears in actual use. i i

` Its operation, andthemanner of' putting `the separate Vparts together, is as follows:

First, the pawl, fig. 2, is turned upon its back, as it were, or, more clearly, in a reverse position to that shown in the figure 2. The journals J J are now entered into the recesses x, iig. 1, the head and neck of the pawl passing into the slotted head of the guide. Now the depression 1, upon the head of the pawl, al-

lows the insertion of the rack, iig. 3, at the lugged.

extremity l, into the guide. The said pawl is now turned over on its -face (its rounded head allowingY this to'be'done after the lug l has passed into the guide)l until its tooth falls between sonne two teeth/of the rack, the weight and leverage vof the projecting main portion of the pawl always insuring its catching, and, as is readily seen, preventing movement of fthe rack, except in one direction'.

The device may now be attached to the windowjamb W, fig. 4, -by means of a screw, passing through the countersunk opening provided in the guide therefor. l I

The point O being driven into the wood, but one screw is requisite tokeep my rack in position; and the head of thistsc-rcw is concealed from sight by the end ofthe pawl being iliade to protectY over it. i

The shade-cord C is now slipped around the head ofthe rack, which may be pressed down until the cord is sueiently taut, when the tooth of the pawl intel'- locks with the teeth in` the rack, thus securely holding -the cord as desired. r

When it may be necessary to loosen the cord, or to disengage it, the end of the pawl mayl be lifted up, when the rackinay be drawn up.

Ido not confine myself to the use of the peculiarly v shaped head of the rack, but substitute a pulley therefor.

I disclaim originality in the mere use, in a window'- shade rack, of' a toothed or ratcheted rack in connection with a catch, such device having. long been in use, and` being now in use in 'various forms; but

What I claim as my .own invention, and am depnrpose, if desired, to

sirons of securing by Letters Patent, is-

The combination of the guide, Iig. 1, provided with the recesses X, or their-equivalent, withthe pawl, tig. 2, working in said recesses, and the movable toothed rack, fig. 3, arranged, constructed, audoperating sub.-

stantially as and for the purpose herein described'and set forth.
