CHARLES NEELY, OF EBENSBURG', PENNSYLVANIA.

SHINGLE-CUTTING DEVICE.

Application filed April 7, 1915.

To all whom it may concern:

Be it known that I, CHARL S NEELY, a citizen of the United States, residing at Ebensburg, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Shingle-Cutting Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved shingle cutting device of that character shown and described in Patent No. 1,092,381, issued to me April 7, 1914.

The present invention has for its primary object to generally simplify and improve the construction of my original invention, whereby asbestos shingles may be expeditiously and accurately out without danger of breaking or mutilating the same so as to render them unfit for use.

It is a more specific object of my invention to provide an improved construction and mounting of the movable knife blade whereby a shearing out upon the material at the necessary pressure may be obtained with a minimum of manual labor.

It is an additional object of the invention to produce a cutting device for asbestos shingles which is highly durable as well as very eliicient and reliable in practical operation and may be produced at comparatively small manufacturing cost.

With the above and other objects in View, my invention consists in the novel features of construction, combination, and arrange ment of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which,

Figure 1 is a perspective view illustrating the preferred embodiment of the present invention Fig. 2 is a transverse section of the device; and Fig. 3 is a section taken on the line 3-43 of Fig. 2.

Referring in detail to the drawing, 5 designates the base or body bar of the device, the opposite ends of which are boltcd or otherwise rigidly fixed upon the blocks or cleats 6. Each of these end blocks is provided with a standard consisting of the spaced vertical arms 7 between which one end of the vertically movable cutter bar 8 is engaged. Upon one face of this bar, the longitudinally extending cutting blade 9 is secured by a series of screws indicated at 10. This cutting blade tapers 1on- Specification of Letters Patent.

Serial No. 19,738.

gitudinally from one of its ends to the other and the cutting edge thereof, indicated at 11, is disposed below the plane of the lower edge of the bar 8. This cutting edge of the blade 9 is very slightly inclined or beveled transversely, and it is in this slight inclination of the cutting edge of the blade that the practical effectiveness of the cutting action resides. To the opposed longitudinal edge of the base or body bar 5, a metal strip 12 is secured, with the upper edge of which the cutting edge 11 of the blade 9 co-acts.

' To the opposite ends of the vertically movable bar 8 and upon the upper edge thereof, the lugs or ears 13 are secured. lever 14 is fulcrumed at one of its ends upon a transverse bolt 15 which is mounted in the upper ends of the spaced vertical arms 7 on one of the end blocks 6. The other end of this lever 1 1 is provided with a longitudinally extending slot 16. A relatively long lever 17 is fulcrumed at one end upon a bolt 18 secured in the upper ends of the arms 7 on the other of the end blocks 6. This latter lever, intermediate of its ends, carries a bolt 19, preferably provided with an anti fric-- tion roller which is slidably engaged in the slot 16 of the lever 14. Spaced links 20 connect each of the leverslt and 17 adjacent its pivoted end, to one of the ears 18 on the cutter bar. A rubber cushioning disk, inclic'ated at 15, for the lever 17 is arranged upon the end of the bolt 15.

It is to be particularly observed, from ref erence to Fig. 2 of the drawing, that the cutting edge 11 of the knife blade 9 is slightly spaced laterally from the edge of the metal strip 12 which is secured to the base 5 so that they will not contact with each other in theoperation of the device.

In the operation of the machine, the asbestos composition shingle is laid. upon the base 5, the asbestos sheet projecting over the upper edge of the plate 12 and beneath'the cutting edge of the blade 9. The operator now forces downwardly upon the free end git,

downward pressure, there will be a shearing cutting action of the knife blade through the sheet of asbestos.

The base 5 of the device is provided with a suitable gage indicated generally by the numeral 21. As this gage is fully shown and described in my prior patent, above referred to, the same will not, therefore, be set forth in detail in the present specification. It will sufiice to state that, by simply adjusting the movable gage bar to the proper position, shingles of any desired dimensions may be quickly and accurately out.

From the foregoing description, taken in connection with the accompanying drawing, the construction, manner of operation, and several advantages of my invention will be apparent. It will be seen that l have materially simplified and improved the construction of my prior invention, whereby the same is rendered more positive and reliable in its action, T he device may be operated with a minimum of labor upon the part of the operator to quickly cut a large number of shingles. lit is apparent, of course, that the body bar which carries the movable cutting blade may be of any desired cross-sectional form as may be requisite in order that the same will have the necessary inherent strength. In view of the fact that the device embodies in its construction but few parts which are all of exceedingly simple form, it will further be seen that the invention can be manufactured and sold at relatively small cost.

While I have shown and described the preferred construction and arrangement of the several elements, it is to be understood that the device is susceptible of considerable modification therein, and I, therefore, reserve the privilege of resorting to all such legitimate modifications as may be fairly embodied within the spirit and scope of the invention as claimed.

' Having thus fully described my invention, what I desire to claim and secure by Letters Patent is l. in a cutting device of the character described, a vertically movable cutter bar, guides for the ends of said cutter bar, levers pivotally mounted at one of their ends upon said guides and connected to each other for relative movement, one of said levers being provided with a handle, and links connected to the respective levers contiguous to their pivoted ends and to the relatively opposite ends of the cutter bar.

2. A cutting device of the character described including a vertically movable cutter bar, guides for the ends of said cutter bar, levers pivotally mounted at one of t 'ieir ends upon the respective guides, one of said levers being provided in its free end with a longi tudinal slot, a bolt fixed in the other lever for longitudinal movement in slot, said latter lever being provided with a handle, and links connected at one of their ends to the respective levers contiguous to their pivots and at their other ends to the rela tively opposite ends of the cutter bar.

3. A cutting device for asbestos shingles incli'lding a base, a metal plate secured t: one of the longitudinal edges of said base, a vertically movable cutter bar, guides upon the base in which the ends of the cutter bar are movably mounted, a cutting blade fixed to one face of said bar and having its cutting edge disposed. below the plane of the lower face of said bar, the cutting edge of said blade being longitudinally inclined with respect to the base to effect a shearing cut, and manually operable means connected to the cutter bar to actuate the same.

4. A device for cutting asbestos shingles includin a base, a metal plate secured to one of the longitudinal edges of said base, a vertically movable cutter bar, guides on the base in which the ends of the cutter bar are engaged, a cutting blade secured upon one face of said bar and having its cutting edge slightly inclined transversely and disposed slow the plane of the lower face of said bar, said cutting edge of the blade being longitudinally inclined with respect to the base to effect a shearing cut, and manually operable means mounted upon said guides and connected to the cutter bar to actuate the same.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

CHARLES NEELY.
