Description

Dec. 5, 1950 J. w. CONWAY CLOTHESLINE PULLEY ASSEMBLY Filed May 21, 194'? Fiyi.

Patented Dec. 5, 1950 UNITED STATES PATENT OFFICE 3 Claims.

This invention relates to a clothesline supporting means, more particularly to a clothesline pulley assembly, and has for an object to provide such a device particularly for supporting the outer end of a double clothesline in such a manner that the line may easily be shifted when loaded with clothes, but also so that both runs of the line can be used for supporting the clothes and the line will be capable of readily running around the pulley while the clothes are supported on it, without difculty, and Without loosening or displacing the clothespins.

Another object is to provide a structure of this character which may readily adjust itself to different conditions and loads, and which is so ccnstructed that the clothesline will always automatically maintain a proper position on the device for most effective operation.

With the foregoing and other objects in view, I have devised the construction illus Jrated in the accompanying drawing forming a part of this specification. It is, however, to be' understood the invention is not limited to the specific dctails of construction and arrangement shown, but may embody various changes and modifications within the scope of the invention.

In this drawing:

Fig. l shows a double clothesline with my improved'assembly supporting the outer end thereof;

Fig. 2 is a section of the device on a larger scale and Fig. 3 is a top plan view'on a somewhat reduced scale.

The usual double run clothesline is indicated at i9 running over a pulley I I of any suitable construction supported at the house on, for eX- ample, a post I2 of a porch where the line is easily accessible, and the outer end is supported on a pole or post I3, for example, from any suitable support, preferablv a hook Ict. The outer pulley assembly comprises a bracket or support I5 comprising a tapered arm I5, preferably a substantially flat strip of metal provided with an opening I1 at its outer end having curved walls to seat over the hook Ibi, the opening preferably being larger than the hook, so that with its curved walls it is free to rock or oscillate on the hook, not only laterally but also up and down,

to accommodate the device to different conditions on the line, as, for instance, should it become slack, or more heavily loaded on one side than the other, or other changing conditions. At its other end, the support I5 is provided with a head portion I8 which is preferably substantially fiat, and between this head portion and the arm portion I6 is offset upwardly and transversely curved, as shown at I9, to provide a` transverse curved groove 2n and at its forward side with an upright transverse curved shoulder 2 2|, the opposite wall 22 tapering gradually from the deepest part of the groove to the under side of the arm.

Mounted in this head portion I8 and depending therefrom is a supporting bolt or stud 23 rigidly mounted in the head portion in any suitable manner. A convenient and satisfactory way is to provide the bolt or stud with a head or shoulder 25 spaced from its upper end, seating against the under side of the head portion 18,-the portion above this flange being passed through an opening in the head IB and threaded to receive a clamping nut 25 whereby the bolt may be securely clamped to this head portion.

Mounted to rotate on this bolt or stud is a pulley construction 25 comprising an upper body portion il and a lower tapered iange portion 23. The upper body portion 2l is preferably somewhat tapered, with its larger diameter at its upper end, and the flange portion 28 is located at the lower end of this body portion and is sub stantially frusto-conical in shape so as to taper downwardly and outwardly from the lower end of the body portion. The angle of the taper may vary, but it is preferably from about 3G to about d5 degrees to the horizontal and should be such as to permit the line with ciothes on it held by the standard type of clothespin 29 to run around the edge without disconnecting the pins. There is also preferably formed at the upper end of the tapered flange portion 28 a horizontal shoulder 39 which is somewhat larger than the diameter of the lower end of the body portion 2l, to thus form a horizontal shoulder or shelf to support the line iii, and prevent it from running down onto the tapered i'iange as the line slaeizens. it is also preferred to provide in the lower end portion of the body portion 2i a shallow groove 3i immediately above the shoulder or shelf 3@ to prevent the line moving up on this body portion on a small slack in the line, which would permit the pulley to swing downwardly a relatively small amount, but would not retain the line against moving up on the body portionv on a much greater dropping of the pulley.

The body portion 2l and the ange portion Z8 maybe formed in one piece, but a much lighter weight construction is substantially that shown in the drawing, in which the body 2l is a hollow relatively thin metal construction closed at its lower end 32, with the tapered flange portion. 23 having a horizontal top wall 33 at the under side of the wall 32 and secured thereto by any suita ble means, such as the rivets 34, the flange portion 28 being also of sheet metal, but of proper gauge to provide the proper strength. A disc 35 may he secured in the upper part of the body portion by any suitable means, such for example, as welding to the body portion, as indicated at 36, to provide an upper bearing for the device on the bolt 23, the lower bearing being provided with the two walls 32 and 33.

In operation, with the line l0 of proper tightness it will run around the groove 3| and on the Shoulder 30. As the clothes are hung on either side of the line they may be adjusted outwardly by shifting the line in the usual manner. As they reach this pulley assembly, they can readily pass around it without being detached from the line when held by the standard pins 29. The lower or depending portions of these pins merely engage the rim of the tapered flange 28, as indicated in Figs. 2 and 3, and this flange will merely cause the pins to be tipped or inclined without loosening or disconnecting them from the line, and they will merely pass around the pulley with the clothes without becoming loosened or detached. Sagging of the device by the weight of the clothes or stretching of the line will not cause the line to run down on the tapered ange 28, but it will be supported on the horizontal shoulder 30 and be retained in proper running position on the body portion 2l'. The taper of this body portion 27 with the largest diameter at the top will tend to cause the line to run downwardly on this body portion so as to automatically locate itself at the lower end thereof unless the outer end of the support I5 with the pulley should drop considerably to cause the line to move upwardly on this body portion. The groove 3l, however, will retain this line at the lower end of the body portion for ordinary sagging of the line and dropping of the pulley, but after it has dropped to a certain angle, say about 45 degrees or lower, the line will run up the body portion 2 into the groove 29. This groove supports the line ofi the pulley and away from its upper edge so that the line cannot jam between the upper edge of the pulley and the support. For best operation, the diameter of the head I8 should be about the same diameter or a little larger than the diameter of the upper end of the body portion 2l. If the head portion is narrower than the upper end of the pulley or of a smaller diameter, there is a tendency for the line to get in between and bind between the edge of the pulley and the support when the line becomes slack and the pulley drops or hangs downwardly at an angle from the hook, and the more the tension the tighter it binds, but with the head about the same diameter as the upper end of the pulley and with this groove 2U in the under side of the support, there is no danger of the line becoming jammed or binding between the pulley and the support no matter how far the pulley may sag or at what angle it may drop from the supporting hook I4. As soon as the line is tightened this device will be automatically shifted to the more nearly horizontal position. and the line will automatically move down the pulley to its normal position in the groove 3| and on the shoulder 30. The curved shape of the opening I1 will permit the device to automatically tip sideways at a considerable angle, even up to as much as about 45 degrees on uneven loading of the line; that is, for example, when all the weight is on one run of the line, or with other uneven loading conditions, the device automatically assumes the neutral position to permit eective running of the line and most easy operation. That is, it lets the pulley accommodate itself to strains from diierent points and different angles. This increases efficiency Ll f) 4 of the line and increases its capacity as both sides can be used.

Having thus set forth the nature of my invention, what I claim is:

l. A clothesline pulley assembly comprising a supporting bar provided with means at one end for mounting it on a supporting hook or the like for tree lateral and up and down rocking movements, a depending bolt at the other end, a line supporting pulley mounted on the bolt comprising an upright somewhat tapered body portion with the larger diameter at the top, a downwardly and outwardly tapered ange portion at the lower end of the body portion, and said bar including a head portion covering the upper end of the pulley and a transverse curved upward recess in the under side of the bar at the edge of said body portieri to receive the line from the body portion ,l and support it on a given dropping of the pulley sagging of the line.
