UNITED `STATES WIRT B. BOYCE, OF CHICAGO, ILLINOIS.
PULLEY.
Application filed January My invention relates to pulleys and particularly to those which are used for window shade control and the like, and which are adapted to lock or bind the cord in any desired weight holding position. The object thereof is to provide an improved device which is practically unbreakable, neat in appearance, noiseless in operation, positive in action, and which can be manufactured at low cost and furnish-ed to the public at a correspondingly small expense.
A practical embodiment of my invention 'is shown in the drawings in which Figs. 1 tollil are, respectively, face, bottom, rear and end views of my improved device; Fig. is a strip of substantially uniform thickness from which the frame or casing is formed; and Fig. 6 is a perspective showing a slightly modified form.
Further describing my invention with reference to the drawings in which like characters of reference denote like parts throughout: The material of the framing of my improved device, as shown in Fig. 5, may consist of a long and comparatively narrow strip of metal of substantially uniform thickness which may be formed by blanking dies into substantially the outline shown. It is then also bent accurately along the dotted lines so that numeral 1 represents the main body portion, 2-2 represent the side walls, 3-3 the re-inforcing or suspension walls, and 4-4 represent the ears by which the completed device is attached to any desired object. It will be observed particularly, as shown in Fig. 8, that in forming the material so that the side walls 2 are in clos-e relation to the re-inforcing walls 3, a very slight spacing 5 may be produced by the spring of the material. It is also to be observed that in the form in which I prefer to manufacture the ldevice the main body portion 1 is in a plane slightly above the attaching planes of the ears 4:. But the side and reinforcing walls may contact with each other, and the body portion may be so formed as to contact with the structure to which the device is attached without departing from the spirit and scope of my invention. The pulley or roller 6 is of well-known form having a central groove 7 and oif-set short channels 8 and 9 leading from the central groove 7 to the peripheral portions 10. l
A pin 15 extends through the pulley and the ends 16 extend through openings 17 in the side walls and form gudgeons which ro- 24, 1925. Serial No. 4,582'.
tate in the bearings thus formed. Bearing the ends of the pulley and the side walls,
thin disks 20, (see Fig. 1) preferably of different metal from that of the frame and the'roller.
Then the device is operated with a cordv passing thereover, the. free or operating endy 25- is drawn over the central groove of the pulley until the weight on the other endv is slight-ly above the point' at which, locking is desired; the operating end is then thrown to the right orleft of the weight Vand permitted to reverse the action of the pulley so that the cord is carried by the grooves 8 and 9 to one side or the other of the pulley so that it is bound or gripped between the grooved portion 26 and the base of the device, as shown in Fig. 2.
As shown in Fig. 6, a part of the main body portion 1 may have a tongue cut therein as indicated by the dotted lines 21 in Fig. 5 and slightly bent upward as indicated by numeral 21 in Fig. 6. The body portion thus raised may be provided with a projection or boss 12 whereby the cord may be more readily controlled in its movements to one side or the other of the clamping roller, and so that. as a whole, the upwardly turned portion will stand in closely clamping relation to the pulley or roller portion 6.
I claim:
1. In a pulley, a casing for a single rollercomprising a continuous strip of met-al including a body portion, a plurality of side walls angularly turned upwardly from the body portion, reinforcing walls secured to the outer ends of the side walls and turned backwardly in close relation to the side walls as a reinforcement therefor, and attachment ears on the reinforcing walls.
2. In a pulley, a casing for a single roller comprising a continuous strip of metal including a body portion, a plurality of side walls angularly turned from the body portion, reinforcing walls secured to the outer ends of the side walls and turned backwardly in close relation to the side walls as a reinforcement therefor, and attachment ears on the reinforcing walls having their engagement faces in a plane below the plane of the body port-ion.
3. In a. pulley, a casing for a single roller comprising a continuous 'stripof metal inoluding a body portion, a plurality of side Walls angularly turned from the body portion, a roller having axial pivot mountings to connect it with the side Walls, reinforcing Walls secured to the outer ends of the side Walls and turned backwardly in close relaltion to the side Walls as a reinforcement therefor, and attachment ears on the reinforcing walls.
4. In a pulley, a casing comprising a continuous strip of metal including' a body portion, a plurality of side walls angularly turned from the body portion, and a roller having` a principal groove and off-set channels leading therefrom to its periphery, and part of said body portion having a tongue cut therein and raised to come. in closer relation to the periphery of said roller.
5. In a pulley, a casing comprising a continuous strip of metal including a body portion, a plurality of side Walls angularly turned from the body portion, and a roller having a principal groove and off-set channels leading therefrom to its periphery, and part of said body portion having a tongue cut therein and provided with a hump adapted to come in closer relation to the periphery of said roller.
6. In a pulley, a casing comprising a continuous strip of metal .including a body portion` a plurality of side Walls angularly turnedfrom the body portion, reinforcing walls secured to the outer ends of the side Walls and turned backwardly out of rigid Contact therewith to reinforce the side Walls, and attachment ears on the reinforcing Walls having their engagement faces in a plane below the lower face of the body portion whereby said body portion and said side Walls are` suspendedly supported by the said reinforcingr walls.
In witness whereof I have hereunto set my hand at Chicago, Illinois, this 12th day of January, 1925.
