Leners Patent No. 93,496, dated August 1o, 1869.

IMPROVEMENT IN Samana-MACHINE.

The Schedule referred to in these Letters Patent and making part of the same.

To all lwhom. ttmay concern:

. Be it known that we, DANIEL B. Slnoxii'r and WIL- LIAM B'UsKIRmof Winchester, in thel county of Clark, and in the State of Missouri, have invent-cd new and useful Improvements in Shingle-Machines; and they do hereby declare that, the following is a full, clear, and exact description thereof', reference being had to the annexed drawings, making. part of this specifica-` a man can work in taking off hand each shingleas.

it is cut, and removing it fmin the knife, to make way for its successor.

In our improvement, the machine is self-clearing, and may .be run by hand, so' as to cut from fifteen hundred to two thousand shingles per hour.

In the drawing- A A are the sills, and

B B are the uprights of our machine.

O is a platform, on which the feeder or attendant stands, and

D is the bed, on which the `block froln which the shingles are cut, is'to rest as it is fed to the machine.

E is the driving-shaft, having at one Vo1 both sides of the machine a fly-wheel, F, which may each be flu'- nished with a crank, when the machine is to be run by hand, or a'pulley, when it is to berun by other than hand-power.

In the centre of the shaft is a crank, l', to the pin of which is connected one end of the pitman G, vthe other end being attached to the knife-sash, as will' be hereafter described.

'lo the uprights B are firmly attached the guides II H, each having a groove, in which'tlie sliding edges of the knife-sash work.

I I are the uprights or slides of the knife-sash, and to ,these hprights is bolted the knife K, as seen i the drawing where. figjl shows a front view,'and iig. 4, an enlarged rear elevation ofthe sash.

I l' are cross-ties, connecting the nprights or slides I l.`

It will be seen, on reference to figs. 3 and 5, that a v space`is'open between the edge of the knife andthe front face of the upper cross-tie 1', through which the shingle will pass, after being separated from its block,

as indicated by the arrow.

lwouprights, a a, extend from one cross-tie I to the other, between the slides I, and two other nprights a a', near the centre of the sash, strengthen it, and

afford a bearing for the pin, to which the upper end of the pitman G is attached by a strap-joint. (See figs. 3, 4, 5, and 6.)

The slides I, cross-ties I', and uprghts a a', may be all .one casting. l

An upright spindle, b, extends from the centre of one cross-tie I to the other, and is made adjustable to or from the front of the machine, by being. allowed to move laterally'in the slots ff, through the cross-ties,

and in which it may be xed by tightening the nut at its uppeil end, while the set-screws c c will prevent it and the gauge-plate L from being forced back, as thc block is brought up against the plate.

By this arrangement is determined and fixed the thckness'of 'the shingle at the middle of its length.

'lfhe gangeplateL is hung upon the spindle b, so as to vibrate in such a manner that the plane of its face may be presented obliquely'to the shingle-block, toward'either side ofthe machine. Y I

The taper of the shingle, as shown in ig. 6, wherethe edge of the knife is represented by the broken and` Adotted line, is determined by the degree of oblique vibration allowed to the plate L, and this is fixed by the temper-screws l d (l (l, which are tapped through the uprights a a. t

To the face of the gauge-plate are attached two springs c e, which may be fixed in recesses in vthe plate,

so that when the block is held against thc plate, the

springs will be Hush with its surface.

These springs extend up above the top edge of the gauge-plate, and behind the knife above its edge, pressing againstJ the back face of the knife, when not forced into their recesses in the plate, as seen in iig. 5.

When a shingle is being out, it passes, as the knife descends, between its rear face and the spring. It is there held whileA the knife ascends to make a new cut,

and as this is done, o n the descent of the knife, the

shingle that -was held' between the springs and the knife is pushed out and rearwards by the shingle that takes its place, and ,is held until it, in its turn, gives place to another. n As the shingles fall, they are conveyed bythe chute or incline M, to a point convenient for bundling.-

Having thus fully described our invention, What we claim therein as new, and desire to secure by Letters Patent, is

The gauge-plate L, in combination with the spindle b, slots f i,.set-screws c c, andv temper-screws d d d d, substantially as and for the purposes set forth.

AIn testimony that we claim the above-described improvements in shingle-machines, we have hereunto signed our names, this 8th day of June, .1867.
