SPECIFICATION forming part of Letters Patent N 0. 404,211, dated May 28, 1889.

Application filed May 21, 1888. Serial No. 274,474. (No model.)

To aZZ whom it may concern:

Be it known that I, FERDINAND MATTIIEY, engineer, a resident of St. Imier, Switzerland, a citizen of the Swiss Republic, have invented new and useful Improvements in Fittings for Blinds, Curtains, and the Like, of which the following is a specification.

My invention has relation to fittings for blinds, curtains, or the like; and it consists in the arrangement and combinations of parts, as hereinafter described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings, Figure 1 is an elevation of the device, the top of the inclosing-casing being removed. Fig.2 is a vertical section thereof, partly in elevation. Fig. 3 is a section, partly in elevation, of the lower portion of the box or casing with the parts therein, showing the position of the parts when the blind is stationary; Fig. 4, a similar view showing the position of the parts when the blind is in motion. Fig. 5 is an elevation of the rack and parts connected therewith. Fig. 6 is a perspective View of the rack and the pivoted angular lever or arm. Fig. '7 is a perspective view of a portion of the casing and the pivoted dog, looking from the rear. Fig. 8 is a perspective view of the pivoted angular lever.

In the above-described figures of drawings, A indicates the curtain-roller, one end of which is journaled in a suitable bracket or lug attached to one side of the window-frame, and its other end being journaled in .a box or casing, 13, attached to the opposite side of said frame. The journal of the roller projects within the casing, and upon it is mounted a pinion, 0. Upon a shaft, (1, passing through the sides of the casing, is loosely mounted a toothed wheel, D, having a barrel portion, F, said wheel meshing with the pinion O on the journal of the curtain -roller. A suitable clock-spring is fitted within the barrel F, the tendency of which is to rotate the wheel D to cause the curtain to be raised, in the manner presently described.

Loosely mounted upon the shaft cl, but secured to the barrel F, is a pinion, E, which meshes with the teeth formed upon the upper end of an arm or rack, N, loosely mounted upon a pivot or shaft, G, in the lower end of 7 The inclined faces just mentioned form angles with a center line from front to rear, as well as from side to side-that is to say, from 1 to 1 there is, as it were, a straight line from the points 2 2 to the points 2 2, and from 1 to 2 2' the under surface of the projecting arm 0 forms an angle, so that the points 2 2 are lower than the line 1 1" and the points 2 2 are below both the line 1 1 and the points 2 2.

P is a coiled spring projecting through a recess, 7r, formed in the arm K of lever L and bearing upon the arm 0 of angular lever O, which latter in turn bears upon a dog, 0', pivoted to a lug, 0 on the casing B to hold said dog in contact with the wheel D to prevent the rotation thereof while under the stress of the clock-spring before described, the face of the dog 0' being serrated to engage with the serrated face of the wheel D.

The operation of my device is as follows: The curtain being stationary, the parts assume the position shown in Figs. 2 and 3. Now, when the lever L is swung on its center it tends to move the piece 0 sidewise. The latter cannot, however, yield in that direction, and the roller K, acting as a cam upon the inclined surface 1 1 2 2, carries the piece 0 from the position shown in Figs. 2 and 3 into that represented in Fig. 4, the spring P being compressed and allowing the dog 0 to fall away from the serrated face of the wheel D and set the latter free. The clock spring then acting upon the wheel D will revolve the latter and the pinion 0 upon the journal of the curtain-roller, gearing with the wheel D, will rotate said roller, causing the curtain to be wound thereon. During the revolution of wheel D the rack N, by meshing with pinion E, will be oscillated upon shaft G, carryin g with it the pivoted lever O, the extremity K of lever L during this movement being held in engagement with the inclined face. If at any point in its travel the lever Ii is released, the spring I, pressing upon the arm 0' of lever 0, causes the roller to ride back upon the inclined face from 2 toward 1, and thereby forcing the pivoted dog 0 into engagement with the wheel D, stopping its rotation and arresting the movement of the curtain.

\Vhen it is desired to lower the curtain, the lever L is manipulated in the manner before described to cause the dog 0' to release wheel I). The curtain is then drawn down by the other hand, and in this movement the pinion (l, meshing with wheel 1), causes the latter and the barrel F to rotate in a reverse direction to that taken when the curtain is being raised, and consequently causing the clockspring to be wound. In this movement of the parts the rack N, by meshing with the pinion will be oscillated to the opposite side of the use, carrying with it the angle-piece O, the arm K of lever L, of course, being still held in engagement with the inclined face to keep the dog 0 out of engagement with wheel 1). \Vhen the curtain has been drawn down suiticiently, the level-arm K of lever L is caused to release the inclined face, thereby allowing the dog 0 to again engage the wheel I).

The rack N, as will be seen, serves merely the purpose of a support for the angle-piece O, and when the curtain is being raised or lowered oscillated on its shaft toward one side or the other of the case, as hercinbel'ore stated.

Having now described my invention, what I claim is 1. In fittings for blinds, curtains, and the like, the combination, with one of the rollerjournals, of a pinion mounted thereon, a toothed wheel engaging with said pinion, acoiled spring operating to rotate the toothed wheel, a spring-actuated lever operating upon a dog to hold the same in engagement with said toothed wheel, and a lever adapted to operate upon said spring-actuated lever to allow the dog to release the toothed wheel, as described, for the purpose specified.

2. In fittings for blinds, curtains, and the like, the combination, with the curtain-roller, of a pinion mounted on one of the journals of said roller, a toothed wheel engaging with said pinion, a pinion adapted to rotate with said toothed wheel, a coiled spring acting to rotate the latter, a toothed arm or rack engaging with the latter pinion, a two-armed lever pivoted to said arm, one limb being provided with inclined bearing-snrfaees, as described, a spring bearing upon the other limb of said pivoted lever, a dog located between the spring-actuated limb and the toothed wheel aforesaid, and an operating-lever adapted to engage with the inclined bearing-surfaces described, said parts being arranged for eo-oporation, as described, for the p u rpose speei lied.
