GEORGE B. COWLES, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO WHITE 85 COWLES, OF SAME PLACE.
Specification forming part of Letters Patent No. 134,980, dated January 21, 1873.
To all whom it may concern:
Be it known that I, GEORGE B. COWLES, of Bridgeport, county of Fairfield, State of Connecticut, have invented an Improvement in Window-Shade Rollers, of which the following is a specification:
My invention consists in attaching the stoppawl to the end of standard to which the end of roll-axle is secured at a right angle to its projection, and in a longitudinal position to the roll, the fulcrum of same extending through the axle to prevent its turning and secure it laterally; and in further providing a circular recess in end of standard for a spring to catch to pawls, it being back of same and out of sight. The ratchet for pawl is cut on the face of flange of roll. The action of pawl being toward the roll longitudinally prevents all rattling of same, and simplicity and cheapness of construction being the object attained.
In the drawing, Figure l is a longitudinal view of roll, showing the standard and attachment of pawl. Fig. 2 is a front view of pawl and iiange. Fig. 3 is a detail of flange, showing the construction of ratchet. Fig. 4 is a section of standard.
Description.
Construction.
The roll A 1 make either of tin or other sheet metal or wood, and provide a coilsprin g and axle the same in form and operation as those in general use, except the ratchet and the end of axle connecting with standard B,
that is round. This standard has a circular chamber turned in its end, and the stud squared oft to give a good bearing for pawl F. To secure the end of axle D to the standard B I drill a hole into the standard on one side, thesize of axle, nearly through. I then drill another smaller hole into the standard lengthwise, down through the hub l and axle D, and fit a pin, E, with head, that secures the pawl F in position and runs down through the axle. To throw the pawl in connection with ratchet, I it a circular spring in groove a, one end secured to the standard, the other to the pawl. For the ratchet I cut three shal low grooves, b b, into the face of Vroll-flange. The form of pawl is such that it operates in the grooves b above the center, and forces the roll endwise against the shoulder 2, and prevents all rattling when the roll is used for a carriage-window.
The operation is as follows: The curtain or shade is rolled up on the roll A. The stands B and C are secured to the jambs of the window by screws through the foot g. The roll is then set in position; the pin E put through pawls 'and axle. The spring is now slaclner nearly so, the pawl F preventing its unrolling. To operate the pawl I attach a cord at the outer end at t',- the shade isl drawn down by the hand to any point `desired and winds up the spring, and the pawl will hold the curtain at any point desired, it working automatically. By pulling the cord the pawl lets go its hold on the ratchet, and the spring unwinds and rolls up the shade, its speed and position regulated by the hand.
What I claim as new, and desire to secure by Letters Patent, is
1. The pawl F, as arranged, or its equiva-I lent, bearing endwise on the roll, by which lateral motion is prevented. y
2. The arrangement ot' the pawl F, ratchet b on ange G, shoulder 2, in combination witlr axle D, secured in standard or its equivalent B, by pin E, as described and for the purpose specified.
In testimony whereof I have signed my name to this specication before two subscribing witnesses.
. Y GEORGE B. COWLES.
Witnesses A. SKAATS, LAURA A. HUBBELL.
