CUTTING ATTACHMENT FO'R CORNICE-BREAKS SPECIFICATION forming part of Letters'latent No. 727,895, dated May 12, 1903. Application filed December 29, 1902- Serial No. 136,880. (No model.)

To alt whom it may concern.-

Be it known that I, GEORGE RANDOLPH BYDE, a citizen of the United States, and a resident of Fresno, in the county of Fresno and State of California, have invented new and useful Improvements in Cutting Attachments for Cornice-Breaks, of which the following is a full, clear, and exact description. My invention relates to certain novel and.

copper, zinc, or any like material may be;- easily and rapidly cut in any desired width by simply inserting the sheet between the holding or clamping jaws of the cornice breaks and moving the cutting means from end to end of the machine, thereby severing the strips or pieces of metal intosheets of standard sizes.

My improvement is also directed to a mechanism of the character heretofore stated which shall be providedwith adj ustable means for clamping or holding the materialso that the sheet may be severed along a predetermined line. It is also directed: to lthecon struction of a machine the cutting attachment whereof shall be brought into bearing engagement with a portion of said machine, said cutting attachment being adjustable and provided with means for holding it in its normally operative cutting position.

With the above-recited and other objects of a similar nature in view my invention consists in the construction, combination, .and' a1:-v rangement of parts, as will .be described in this specification, delineatedin the aocom'pae nying drawings, and set forthinthe appended claims.

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

Figure 1 is a view in front elevation of a machine embodying myimprovements. Fig.

2 is a view taken transversely through the cutter.

strengthened by braces 1". frame'are mounted the parts forming an ormachine on the line 2 2 of Fig. 1; and Fig. 3 isa sectional view on the line 3 3 of Fig. 1, illustrating the mounting of the adjustable Referring now to the accompanying draw- .ings in detail, wherein I have shown an embodiment of my invention, 1 designates the base or main frame of my machine, which may be of any desired character and which is Upon this basedinary cornice-break, such parts consisting of the jaws or clamping-bars 2, and 4 and the shaft 5. Upon the machine are mounted vertical standards 6,, which support the horizontally-disposed guide-rails 7 and 8. The

construction just described will be clearly observed by reference to Fig. 1 of the drawings. These parallel guide-rails 7 and 8 are adapted to support a traveling carriage 9,

which carries the cutting mechanism of the machine, the construction of which carriage j I will now proceed to describe in detail.

Referring to Fig. 2, it will be seen that such carriage is formed of two vertically-extendingwalls or sides.10 10, connected at their end portions'byintegrally-formed curved portions 11 11,- which curved parts of the carriage are adapted to form slides through snugly fit'any-size machine, I have provided a set screw 14, which extends through apertures in the'sides ofsaid carriage.

' The cutting mechanism which I employ is adjustably connected with said carriage and comprises a vertically-arranged arm 15, adjustably secured to said carriage through the medium of set-screws16 16, the said arm carrying at its lower free enda' horizontally-disposed t'ubular sleeve 17, the sleeve and its vertical arm forming a bracket or holder for the cutter. A cylindrical shell or casing 18 is removably held in said sleeve 17 through the medium of a set-screw 19, and the rear portion of the casing, as at 20, is provided with a contracted bore 21, through which extends an adjustable screw rod 22, having thereon a locking-nut 23, which nut bears against the rear wall 24 of said shell or eas' ing. As will be evident upon examination of Fig. 3, this shell forms a housing for the cutter of the machine, and while such cutter may be of any desired sort still I prefer to employ one substantially as shown in said figure, the cutter comprising a cylindrical shank 25, carrying a cutting-disk or circular head 26 at its outer end, such shank having a normal outward pressure exerted thereon through the medium ofa coiled tension-spring 27, located between the end of said shank and a bearing-disk 28, such disk fitting snugly within the bore or shell of the casing and being adapted to be moved along the same through the medium of the screw-rod 22, whereby the spring tension or pressure upon the shank of the cutter may be varied or regulated.

Through the lower clamping bar or jaw 2 of the machine extend the relatively long screw-threaded rods or shafts 29, these rods or shafts carrying at their end portions 30 the upward'extending spring guide-arms 31, which bear against and form a rest and guide for the material to be operated upon by the cutter, said spring guide-arms being adjustable along the portions 30 of the rods or shafts 29 by tightening or loosening the set-screws 32, extending through screw-threaded apertures in the lower ends of said spring guidearms and bearing against the aforesaid rods or shafts.

For the purpose of forming a bearing-surface for the cutting-disk during its course of travel across the machine I secure a bar 33 to the upper edge of the jaw or clamping-bar 2 of the machine, the cutter being pressed or held against this bar by means of the tension-spring hereinbefore described, thereby insuring that a straight accurate cut shall be made in the material or stock.

For the purpose of holding the threaded arm of the cutting-bracket in any desired position I may employ suitable bearing-blocks 34 34, which are interposed between the aforesaid vertical arm 15 and the sides of the carriage. WVhile I have shown said blocks in the present instance (see Fig. 2) of cubical form, they may for some purposes be beveled, so that the cutter may be tilted at any desired angle.

From the above description, taken in connection with the drawings, the construction and operation of my improved mechanism will be readily apparent. The sheet of metal, which I have shown in. the present instance at A, is clamped between the jaws of the machine, and the cutter-carrying mechanism is adjusted upon the carriage, so that a strip of desired size may be severed. If necessary,

the cutter is also adjusted in the sleeve of the bracket and the spring-arm is moved along upon its red a suiiicient distance to act as a guide or support for the aforesaid cutting mechanism. The cutter is then moved across the machine by grasping the handle and pushing or pulling the carriage, and a strip of desired size is cut from the sheet.

While in the present instance Ihave shown and described one particular embodiment of my invention, it will of course be understood that I do not limit myself to the precise details of construction shown herein, as there may be modifications and variations in some respects Without departing from the spirit of my invention or sacrificing any of the advantages thereof. For instance, it is to be understood that the guides for the traveling carriage may be made of any shape other than that herein shown, and the adjusting means for the cutter and its bracket may also be varied, the main object being to obtain a clamp and adjustable gage for a sheet of metal to be cut and then to out such metal by means of a disk movable across the surface of the sheet of metal.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
