IMPROVEMENT IN APPARATUS FOR CLASPING HooP-sKiR'i-s.

Specification forming part of Letters Patent No. 50,728, dated October 3l, 1865- To all 'whom it may concern Beit known thatl, CHAUNCEY L. OLMsTEAD, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Apparatus for Clasping Hoops to Hoop-Skirts and similar Articles 5 and I do hereby declare that the'following is a full, clear, and exact description of my said invention, reference being had to the accompanying drawings, in which- Figure l represents a vertical longitudinal section of a part of a hoop-clasping machine with my improvements applied thereto. Fig. 2 represents a top view ot' a part of the machine, looked at in the direction of' the arrow a, Fig. l; and Fig. 3 represents a transverse section of a part ofthe machine at the line xx ot' Fig. 2, seen in the direction ofthe arrow b.

My improvements relate to the feed mechanism ot hoop-clasping machines. In such machines 4the clasps are placed promiscuously in a slightly-inclined pan-hopper, from which the jar of the machine causes them to escape and pass to the upper end of an inclined feedingplate, down which they slide to the clasp-supplying device, which holds them in line and supplies them in succession to the clasping mechanism. During the passage of the clasps down the inclined feeding-plate they come in contact with inclined directing-bars, whose function is to cause the clasps to arrange themselves, with their tongues, in the proper positions they are to occupy in order to be received into the clasp-supplying device. The operation of such bars has been found by experience to be inadequate tothe requirements of the machine, and, besides, many clasps which do not attain their proper positions pass over the entrance ofthe feed-supplying device and are scattered on the iloor, thus occasioning material loss.

The object of my improvements is to render the delivery of the clasps to the clasp-supplying` device more certain and to lessen the loss ot' clasps.

To this end the i'rst part of my improvement consists ofthe combination ofthe feeding-plate with what I term a needle, consisting of a thin pointed rod secured to the feeding-plate in advance of the passage to the feed-supplying device, with its point extending toward the clasp-hopper, so as to act upon the clasps as they descend and permit such only as have attained the requisite position to pass into the feed-supplying device.

rlhe second part ot' my invention consists of the combination otthe feeding-plate with a gate placed in the passage to the feed-supplying device, and having an opening in it to per,- mit the clasps which have been properly arranged to escape one at a time, but closing the remainder of the passage in such manner as to prevent the escape of misarranged clasps and insure their delivery through an opening communicating with a receptacle in which they are caught.

As the construction, arrangement, and mode of operation otmachines for clasping hoops to hoop-skirts are well understood, I do not deem it necessary to represent and describe a complete machine, but I have represented in my drawings all the parts of the machine to which my invention appertains. The remaining parts ofthe machine maybe constructed as described in the Patent No. 37,124, granted to Jedediah Wilcox, assignee ot' Joseph H. Baird, the 9th day of December, 1862.

The hopper A of the machine consists ot' a shallow pan, slightly' inclined and having an opening, d, at its lowest part, from which the clasps escape by the jar of the machine and pass to the feeding-plate B. The feeding-plate is inclined in the usual manner. It is litted at one side with a bar, C, which prevents the escape of clasps, and at the other with an inclined guide-bar, D, having a groove or opening at its lower side to admit the flanges of the clasp, and so located in respect to the opening ofthe hopper from which the clasps escape that they come in contact with it, and by sliding down in such contact are caused to arrange themselves with their tongues in proper positions to enter the clasp-supplying device E. The side bar, O, and guide-bar D converge, so that their lower ends form a narrow passage through which the clasps pass to the entrance l the two. Hence, as the clasps pass down the feed-plate in contact with the guide-bar D, such as have been properly arranged enter readily the channel-way between the point of the needle m and the guide -bar D, while the bulk of the misarranged clasps are directed away from the guide-bar by the point of the needle and pass through the escape-slot f to the spout G leading to the catch-box H. Occasionally a misarranged clasp may escape the action of the needle, but this is a rare exception to the general rule.

In order that the misarranged clasps may not pass through the passage between the side bar, C, and guide-bar D and fall to the Hoor, a gate, 7i, is applied to this passage. This gate crosses the passage at an angle, so as to direct such clasps as pass over the needle m into the escape-slotf, butit has an opening, e,
