MACHINE FOR RIVING SHINGLES, &C.

Specication of Letters Patent No. 13,155, dated July 3, 1855.

To all whom zt may concern.'

Be it known that we, A. C. BILLINGS and B. H. RUGGLES, of Palmer, in the count-v of Hampden and St-ate of l\'lassachusetts, have invented a new and Improved Machine for Cutting or Riving Shingles, Staves, &c.; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a vertical longitudinal section of my improvement; Fig. 2, is a horizontal section of ditto, (fr) Fig. 1, showing the plane of section.

Similar letters of reference indicate corresponding parts in the two figures.

The nature of our invention consists 1st, in the peculiar means employed for giving the necessary feed motion to the carriage and 2nd, in the employment of ayielding or elastic head -s tock which will be fully vdescribed hereafter.

A, Fig. 1, represents a frame constructed in any proper manner to support the working parts of the machine.

B, represents a transverse shaft which works in suitable bearings on the lower part of the frame A, said shaft having a toothed wheel C upon it which wheel gears into a pinion D, on a shaft E, which is parallel with the shaft B, and also has upon it a fly wheel F, and driving pulley, the shaft E, being the driving shaft.

G, represents a curved lever, one end of which is connected by a bolt or pin (a) to one end of the lower partof the frame A. This lever has a curved slot (b) made through it, in which slot a pin (0) attached to one side of the toothed wheel C, fits or works, see dotted lines Fig. 1. The opposite end of the lever Gr, is connected by a link H, to the lower cross piece of a vertical reciprocating gate I, which works in suitable guides (d) att-ached to the frame A. To the upper part of the gate I, the knife J, is attached which is in a horizontal position, its lower edge being the cut-ting edge.

On the upper part of the frame A, there are placed two ways K, K, one of which is shown in Fig. 1. Between these ways a carriage L, is fitted and works. To the under side of the carriage a rack M, is attached as clearly shown in Fig. l. On the upper surface of the carriage L, and between the ways K, K, of the carriage a head stock N, works, said head stock being provided with a clamp O, at its upper end. The clamp O, may be constructed in any proper manner and secures the block from which the shingles are cut to the vertical portion of the head stock. The head stock, considered as a whole, is formed of a hori Zontal plate (e) which is the part which rests on the carriage L, and is fitted between the ways K, K, as previously described, and a vertical part (f) to the upper end of which the clamp O, above mentioned is attached. The plate (e) of the head stock is attached by a spiral spring P, to the carriage L, said spring tting in a recess in the carriage, see Fig. l. To the upper part of the frame A, underneath the carriage L, there is a lever Q, which works on a pivot (g) attached to a small horizontal arm (72.) on the frame, see Figs. 1 and 2. At the back part of this lever and at one end there is a spring (i) which keeps one end of the lever against. the side of one of the uprights (j) of the gate I. At the lower end of this upright (j) there is attached a small inclined or wedge shaped projection the edge of which is uppermost as shown in Fig. 1. To the opposite end of the lever Q, there is attached by a pivot (l) an arm (m) having a pawl (n), secured to its end, this pawl is kept in the teeth of the rack M, by a small spring (o) attached to the arm (m). The pawl (Z) has a lever (p) attached to it, the outer end of this lever projects through the side of the frame A, see Fig. 2.

The operation will be readily understood. Mot-ion is given the driving shaft E, in any proper manner, and as the toothed wheel C, rotates the pin (c) thereon in consequence of being fitted in the curved slot (b) of the lever G, gives said lever a vibratory movement and the gate I, is consequently operated with a vertical reciprocating movement.

The block from which the shingles are cut represented by A', is secured to the part (f) of the head block N, by the clamp O, the grain of the block being in a vertical position. When the gate I, has nearly reached the length of its upward stroke, the inclined or wedged shaped projection (7c) will act against the end of the lever Q, and the pawl will act against the rack M, and feed the carriage L, along so that the edge of the block will be underneath the knife J, in the gate I. The carriage is fed or moved a certain distance at each stroke of the gate and at a proper distance equal to the desired Width the shingle is to be cut. The head block and carriage are shoved back by hand by operating the lever (7?) and throwing the paWl from the rack. The spring P, allows the head block N, and

block A, to yield or give in case of any re-V what We claim as new, and desire to secure by Letters Patent, is

l. 7e claim giving the proper feed motion to the carriage L, by means of the inclined or Wedge shaped projection (7c), on the gate l, lever Q, and paWl (n) which acts against a rack on the under side of the carriage L, as herein shown and described.

2. We claim connecting or attaching the head block N, to the carriage L, by lneans of the spiral spring P, for the purpose of allowing the head block to yield or give when necessary as herein set forth.
