Description
Peiuited tait/lt @wat @fina `SOMMERS CROWELL, OF PHILADELPHIA, PENNSYLVANIA.
Letters Patent No. 86,139, dated Janna/ry 26, 1869; antedated January 4, 1869.
,IMIPROVED CLOTHES-LINE STRETCHER.
The Schedule referred to :in these Letters Patent and making part of the lama To all whom it ma/y conce/rn In the accompanying drawings, which make a partof this specification- Figure 1 is an isometrical v iew of the improved device.
Figure 2 is a like view of the bracket B, the sheave v A and cap D being removed.
Figure 3 is a sideelevation of the-sheave A detached.
Like letters, in all the igures, indicate the same parts.
A is a sheave, around which the line is stretched. There is one sheave situated at each turn of the line.
B is a bracket, which supports the sheave.
The latter is castvtround a rod, the lower end of which constitutes a journal, C, to the sheave,.and has a head, a, on its end, which, coming against the under side ofthe plate b ofthe bracket, prevents the journal slipping upward when the line has an inclined position given to it 'by being propped up, which position has a tendency to raise the sheave and draw the journal from the bracket.
The metal at the end of the plate' of the bracket is cast around `livets c c, by which the cap D is confined to the end of the said plate b, to hold the jonr-V nal G in place, The rivets are clearly seen in fig. 2.
The plate d of' the bracket has screw-holes e cast in it, for the purpose of confining it to the fence.
I also cast the rivet-holes in the cap D, and have no drilling whatever in any part of the device; and there being no fitting required, it can be made very cheap, and consequently be brought within the means of every housekeeper.
What I claim as my invention, and desire to secure by Letters Patent, is-
As a new article of manufacture, a clothes-line stretcher, consisting of a sheave, A, having an enlarged head, A', cast with a journal, C, and flange a, and working in a bracket, B D, formed of two pieces, ll as shown and described, and for the purpose specied. A
In testimony that the above is my invention, I have hereunto set my hand and affixed my seal, this 7th day of 1868.
