EDXVARD HEDLEY, OF MEDINA, NEWv YORK.

SHINGLE-MACHINE.

Specification of Letters Patent No. 14,914, dated May 20, 1856.

To all whom it may concern:

Be it known that I, EDWARD HEDLEY, of the village of Medina, Orleans county, New York, have invented a new and useful Machine for Planing and Shaping Shingles, called Hedleys Rotary Shingle-Machine; 7 and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings and model.

The frame work A, A, is of timber or iron about twelve feet long by 3 feet high and from 2 to 3 feet wide. The cylinders B, B, are fixed upon and above the frame work. Each of said cylinders is to be from eight to ten inches in diameter and in length from three to four feet and hung on gudgeons of solid brass or other suitable metal with close boxes of proper metal. Each of said cylinders is furnished with from two to five planing knives of about 18 inches in length made of the best kind of steel, the shafts at each end of the cylinders projecting beyond the frame work from three to nine inches. This is to furnish proper room to attach pulleys for bands to play upon. The first of said cylinders is about the middle of the frame work. The second cylinder is placed about four feet farther forward upon said frame work and nearly on the same level as the former and both are to play above an apron or belt composed of leather chains and metallic plates c, c, c. This apron or belt is composed of two leather bands or chains of iron of sufficient length to play over four pulleys D, D, of about two feet 3 inches in diameter fixed near the ends of the frame work aforesaid. These two bands or chains are covered and connected together by a series of iron plates c, c. Each plate is composed of three pieces of metal. The whole plate if entire is to be 18 inches square. On the underside of each plate are three metal ribs cast on the plates, one on the center and the other two near the out edge of the plate. The bands or iron chains go between the ribs or grades and are attached to the plates by rivets or other ways of fastening. The ribs or grades are double and wedge shape so as to give the proper taper to the shingle by running on solid bars of iron placed under the ribs or grades. These rails are about six feet long and about 12 inches apart and parallel to each other about one inch thick by 4 wide and from the end of these rails are three other of the same size and kind and placed one inch nearer the center of machine than the last mentioned rails to the front end of the machine or finishing end. The rails in all cases are exactly under the ribs or grades on the plates of the apron aforesaid. In front of each of the revolving cylinders is a roller E, fixed on springs and very near each cylinder to draw the rough shingle in toward the knives. There is also one placed behind the knives to draw it out and keep the shingle down to the bed, between the hind roller and the knives are two gages set to keep the shingle from chattering one close to each knife or set of knives. The machine is set in motion by steam, water or horse power applied to a drum or pulley F. On t-he same shaft are two pulleys G, on which bands are extended to the ends of the cylinders H, H, and by cog work the ends of the drums or pulleys which drive the apron. The winch or endless chain j drives the four rollers E, E, by cog pulleys attached to the rollers and at the same speed as the apron moves.

The machine being in motion the apron moves at about 40 feet per minute and the cylinders in the same time make 2,500 or 3,000 revolutions. The rough shingle is placed on the metal bed or carriage with the butt against the angle on the plate and passes toward the first cylinder. In its passage it is lirst secured and passed down to the plate by a roller then under the cylinder. As the shingle passes under the cylinder the grades on the under side of the plates or carriage gradually raise the hind end of the shingle so when it has passed the first cylinder it has received just the bevel desired and is made true and smooth as can be desired on one side. It is then turned on the same bed by an attendant and passes under another roller and then passes under the second cylinder the hind end of the grades gradually rise to asecond angle. The shingle emerges from beneath far more perfect and smooth than can be made by any process of shaving known to man and at the rate of about from two to four thousand per hour7 and requires the attention less feeding bed of beveled slats, so as to of a man and boy to feed and turn the shingive the required taper to the shingle as it 10 gle. The machine requires from two to passes beneath the knives Substantially as four-horse power and will do the work of set forth in the original specification.

5 twenty men per day and supply an article EDWARD HEDLEY. [n s] of shingle as near perfect as can be made. Witnesses:
