Description
NITED Patented December 1 1903.
ALBERT J. PERKS,IOF SPRINGFIELD, OHIO, ASSIGNOR TO WEBSTER dt PERKS TOOL COMPANY, OF SPRINGFIELD, OHIO, A PARTNERSHIP.
PAPER-remmen.
SPECIFICATION forming part of Letters Patent No. 745,515, dated December 1, 1903.
Application tiled October l. 1903.
To all whom t may concern:
Be it known that I, ALBERT J. PERKS,a citizen of the United States, residing at'Springfield, in the county of Clark and State of Ohio,
have invented certain new and useful Improvementsin Paper-Trimmers, of which the following is a specification.
My invention relates to improvements in devices for trimming the edges of wall-paper ro and similar uses; and it relates particularly to that class of trimmers designed to be used with a straight-edge or gage to which the trimmer is applied and in connection with which it works.
My invention consists of the constructions and combinations of parts hereinafter described, and set forth in the claims.
In the accompanying drawings, Figure 1 is a perspective view of my improved device zo shown in position on the support or straightedge with which it is adapted to work. Fig.
2 is a side elevation of same. Fig. 3 is an end elevation, partly in section; and Fig. a
is a perspective view of the straight-edge or support slightly modified.
Like parts are represented by similar characters of reference in the several views.
In the drawings, u, represents a main frame or supporting-head, which is preferably cast 3o or otherwise formed integrally with a handle c', aknife-receiving recess a2, and a backwardly-extending gage and spring-support a3. This gage or spring-support a3 is provided on one side with a depending flange o4' 5 and on the other side with a similar depending flange a5, the latter, however, being preferably formed separate from the main body and vsecured thereto by screws or otherwiseV for convenience in manufacture and assembling. Secured to the iiange a5 and adapted to extend inwardly parallel with the bottom of the gage portion c3 there is a spindle b, which carries a roller b', the distance between the upper periphery of the roller b' and the lower surface of the lgage portion c3 being sufficient to admit the ange c of the straightedge or support c. From the top of the gage or support as there extends forwardly a liat spring d, in the end of which is journaled a 5o roller d'. This spring d is made of such shape and length that the roller contacts at piece, the main body of Serial No. 175,284. (No model.)
all times with the top of the frange c' when the device is in position for operation, and when in this position the spring d is under tension. The spring is of such length and shape that the roller contacts with the iiange at a point between the handle a', where the power is applied, and the roller b', the construction being sueh that with the spring under tension there is a tendency to tip the main frame forwardly and seat the gage as squarely upon the tlange c', with the roller b pressed upwardly on the under side of the said fia-nge c. The roller d in the end of the spring, however, being located between the gage and the point where power is appliedthat is, the handle CLL-when pressure is exerted on said handle the tendency will be to tip the frame about the roller b'. This, however, will be resisted by the roller d', and as the spring is pressed the rear portion of' the gage will be elevated, turn on the roller d as a pivot, and the entire tension of the spring with the pressure exerted thereon will be received and divided between the rollers d and b', so that the device will be practically relieved from friction in the operation.
The straight-edge or support which I preferably use `in connection with this device is made of metal, preferably of a single integral which is bent to form bearing edges c2 and c3 at each side thereoi` and then bent upwardly to form the liange c', on which the cutter is carried.
By this construction I provide a very simple cutting-outt. The metal which I prefer for the straight-edge is aluminium, making avery light stiff support or straightedge, not liable to the shrinkage and swelling which affects the accuracy of wood in straight-ed ges. The placing of the roller d in the end of the spring and balancing the forces upon the rollers d' and o' renders the device of very light operation and practically removes all friction from the same when it is in use or in the act of cutting.
Having thus described my invention, I claim- '1. The combination with the straight-edge or support formed of a single piece of metal, the main body of which has a bearing-surface on each side as described, and the inwardlyroo l projecting flange supported by the upturned edge or web, and a cutter having a gage portion to embrace said ilange, a roller under said flange and a spring also provided with a roller on the upper portion of said flange, substantially as and for the purpose specied.
2. In a paper-cutter, the. combination with the main su pporting-head havinga forwardlyextending handle and an upwardly-extending gage portion, said gage portion being provided with downwardly-extending flanges on each side and an inwardly-extending fulcrum-roller in connection with a spring secured to said gage portion and extending forwardly but ending between said handle and said fulcrum-roller, said spring being curved downwardly and having a roller journaled in the end thereof, substantially as and for the purpose specified.
3. The combination with the recessed head having a handle, the gage portion, withthe inwardly-extending roller and the spring on said gage portion also provided with a roller, substantially as and for the purpose specified.
4. The straight-edge formed of a single piece of metal having the main body thereof provided at each side with bearing-surfaces and an upwardly-extending web which is bent inwardly to form an overhanging supportingiiange, substantially as specified.
In testimony whereof I have hereunto set my hand this 26th day of September, A. D. 1903.
ALBERT J. PERKS.
