JOHN H. PARSONS, OF QUINOY, MICHIGAN.

IMPROVEMENT IN UMBRELLAS.

Specification forming part of Letters Patent No. 51,616, dated December 19, 1865.

To all whom it may concern:

Be it known that I, JOHN H. PARsoNs, of Quincy, in the county of Branch, and in the State of Michigan, have invented a new and useful Improvement in Umbrella-Frames and I do hereby declare that the following is a full and exact description thereof', reference being had to the accompanyingdrawings and the letters of reference marked thereon.

The nature of my invention consists in the use of a knucklejoi'nt in each ot' the bows of an umbrellaframe, which, when in use, are kept straight by the use of a small cone-shaped slide fitting closely over the joint. The stat't'I construct in two parts, screwing together in or about the middle. The object of the knucklejoint in the bows is that they may be folded together and occupyonly haltl the space that they do when in use. The staff also being made in two parts, by unscrewing the lower part the two in length occupy the same as the bows.

For a more exact and detlnite description of my invention, its construction and operation, reference is made to the accompanying' drawings, in which- Figure 1 is a perspective view; Fig. 2, arcverse section. Fig. 3 represents the manner in which the frame is closed or folded.

Let Fig. l represent an umbrella frame opened or spread, the left-hand part showing the frame, and in which are the improvement I claim: lettera, the staff; letters b b b, the bows; letters c c c, the rods running from the slide h on the staff a. I make a knuckle-jointin e'ach of the bows at the point g, the object of which is that the lower part of the bows may be turned parallel with the upper part. I attach the upper ends of the rods c c c to a movable cone or slide, d, which can be slid up or down the bows. By sliding them down over the joint at g they it closely over the joint and on a concsha-ped ferrule at E, just below the joint, and make the bows straight and firm at the joints g.

For a more distinct description of the operation of the bow and slide reference is made to a sectional view in Fig. 2, in which- Let letter b represent a detached bow. The knuckle-joint will be seen atp/,just below which is a ferrule on the bow. rIhis ferrule is made cone-shaped, so that the slide el may fit closely over it and hold the joint firm. The coneshaped hollow slide d is made to slide up or down the bow by the rod c. In order to keep the slide d closely tted over the ferrule, I use the small tigh tly-titt-ed slide I, which is pushedlower part ofthe bows will at once fall back parallel with` the upper part, as represented in Fig. 3 at band J. The staffbeing unscrewcd, the two parts may be laid side by side, as at a a, and by attaching a band around the whole the umbrella is folded for packing or traveling purposes.

The umbrella Iconstruct in any of the known ways to which I apply the above-described improvement. The slides or hollow cones are made ot' any durable metal. The small tight slides are made of rubber or fine leather, inclosed in ametal band to insure its durability and fit tightly to the bows.

I claim as a new and useful improvement in umbrellas- The arrangement herein described of the knuckle-joints, the conical and tight slides, the ferrules, and the detachable and folding staff, substantially as described.

SIMM SPRAIMAN, G. O. BAILEY.
