To al?, whom/ z'ft may concern:

Be it known that I, ALPHONSE ZAoi-IAEY BoDEEAUx, a citizen of the United States, and a resident of Berwick, in the parish oi' St. Mary and State of Louisiana, have invented a new and Improved Shingle-Machine, of which the following is a full, clear, and exact description.

This invention relates particularly to attachments to shingle-sawing machines in which the saw rotates in a horizontal plane, the object being to provide a simple device for ejecting the spalts from the machine instead oi' manually removing the same, as is the usual practice, thus obviating the possibility of cutting the attendants hands or lingers by the saw.

I will now describe a shingle-machine embodying my invention and then point out the novel 'features in the appended claims.

Reference is to be had to the accompanying; drawings, forming a part of this specification, in which similar characters oi' reference indicate corresponding parts in all the figures.

Figurel is a plan of a shingle-machine embodying my invention. Fig. 2 is a longitudinal section thereof. Fig. 3 is a sectional View showing a slight modiiication. Fig. 4 is a perspective View of the Spalt-ejector, and Fig. 5 shows a setting device therefor.

It may loe here stated that in Figs. l and 2 I illustrate what is termed a double-block machine, and in Fig. 3 is shown a singleblock machine.

Referring iirst to my invention shown in Figs. 1 and 2, 1 designates the bed-plate or table of the machine, and 2 a carriage movable lengthwise thereof through the medium of links 3 and a crank 4. These parts are of the usual construction, as are also the tilt-tables 5. arranged at opposite ends of the machine.v Mounted to swing on cross-bars 6 at the ends of the machine are ejectors consisting of spring-actuated plates 7, which extend inward, the upper members of the springs 7 being arranged to engage against the under sides oi' theI plates 7. From each plate 7 a latch-hook 8 extends downward and is designed to engage with a locking-bar 9, pivotedv at one end to a side rail of the bed-plate, as at 9b, and having its opposite end extended through an opening in the opposite side of thebedplate or table, and the bar is held yieldingly in its locking position by means of a spring 1.0. The lower end of the hook 8, it will be noted, is inclined so that when the spring is pressed downward the incline will force the locking-bar 9 outward until the hook passes the same. Then the spring 1() will draw the bar into engagement with the hook. The plate is pressed downward to its locked position by means oi' a presser 11, which projects downward from an end bar of the carriage. This presser is in the form of a bolt carrying a roller Il for engaging directly with the plate.

In the example shown in Fig. 3 the construction is practically the same, excepting that it is a single-block machine.

ln operation when blocks are placed in the carriage and the carriage reciprocated the devices ll will press the ejecting-plates downward to their locked position, where they will remain during the sawing oi' the block into shingles. When the block is reduced to a spalt and as the spaltis over a plate 7, the attendant by moving' the bar 9 releases the spring, so that it throws the Spalt outward, as indicated by dotted lines in Fig. 3. Two spalter push-blocks 9 are provided on the cross-bar carrying the plate 7 and serve to prevent a spalt from getting' under the original push-blocks on the carriage. .In the single-block machine two narrow blocks may be placed side by side. 'The outer block, or the block nearest the end of the carriage, may be oi less height than the inner block, and therefore it is more quickly reduced to a spalt, and when this point is reached and the spalt is over the spring it is ejected, as above mentioned.

It will be seen that by my invention an attendant that may be only slightly familiar with the shingle-sawing device having the horizontally-acting saw 13 may readily operate the machine without danger of cutting' his hands or ingers. In other words, it does not require a skilled sawyer to operate the machine.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a shingle-machine having a horizontally-rotating saw and a reciprocating carriage, a spalt-ejecting spring-actuated plate attached to a fixed portion oi' the machine, a locking device for the spring-actuated plate, and a device on the carriage for moving the plate to locking position.

2. In a shingle-machine having a horizontally-rotating' saw, a reciprocating carriage, a

spring-actuated plate attached to a xed portion of the machine and having a downwardlyextended hook, a presser carried by the carriage for moving the spring-plate downward, and a locking-bar for engaging with said hook.

3. In a shingle-machine comprising a horizontal saw and a reciprocating carriage, a Spalt-ejector comprising a spring-actuated plate attached to a fixed portion of the machine and having a downwardly-extended hook, a bar extended across the machine and .pivoted to one side thereof, a spring connec-
