' CUTTING-MACHINE.
To all whom z'tmay concern: "Be it known that 1, JOHN C. BACKERT, a
' citizen of the United States, residingat the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful I mprovements in Cutting-Machines, .of which the following is a full, clear, and exact de-.
, scription.
This invention relates to machines for cut ting printers rules, slugs, or other simllar material, and aims to provide improved material gaging and holding means, in addition to other features. I V
A preferable embodiment of my improvement is described in detail in the follow-j ing specification, taken in connection with the accompanying drawings, formlng part thereof, and in-which V Figurel is a top plan view of an assembled cutting machine embodying the im provement of the present invention. Fig. 2 is an end elevation of the machine shown in Fig. 1, partsbeing broken away. Fig. 3 is a fragmentary top. plan view of the cutting machine with the work back and gage positioned to giveacutting bevel to the material cut, this view illustrating the use of the filler angle gage block. Fig. 4 is an enlarged fragmentary section on the line 4-4 of Fig. 1. Figs. 5 and 6 are perspective detail views respectively of the workclamp and filler-block.
Referring to these drawings by numerals, 1 indicates the'base from which rises the standard 2 of a supporting frame, the beds plate of which is indicated at 3, this plate being suitably grooved to receive the guiding'tongues 4 of a sliding work-table 5 in the usual manner in'machines of'this class. This work-table 5 adjacent one end'has an up-standing and overhanging arm 6 from which theupwardly extending arm 8 of a swinging back 9 is pivotally supported, as indicated at 7. This back provides a back-rest for work placed on the table and cooperates with a gage, as will beseen later. Thisback forms a hollow structure having parallel longitudinal sides connected by spanning bars, the bar at one en'dbeing continued and, up-turned to .fOIIh, the hinging arm'8. One of these longitudinal bars, indicated at 9*, forms the actual back against which the work rests and is preferably pro- .videdwith a scale which has reference to a gage cooperating with the back. The back 9 may be held at various angles relative to the far edge of the table5. To this end a pin 10 is suitably mounted in the" frame on the back and cooperates with. angle holes 11 formed in the table. 5 to position the face of the back .bar.9 at reverse; angles relatively to the table and relatively'to a cutting tool positioned adjacent this edge and parallel therewith. These angle holes 11 represent, in the present instance, reverse angles of 45 from the right angle or a- 90 line, in which the back is held as shown in Fig. 1, in which position the pin 10 cooperates with a 90 hole 12 in the table (see Fig. 3). a
.The standard 2 of the machine frame is provided with journals 13, in which is mounted the shaft 14 of a cutting, tool, a fly-wheel 15 and operating handle 16 being provided for this shaft. The cuttingtool is in the form of a rotatable disk cutter 17' of suitable design and construction, the inner face of this disk lying in a plane closely adjacent to and parallel with the adjacent edge of the table 5. It will be evident that the table 5 may be moved by one hand of the operator toward the cutter while with Specificationof Letters Patent. Pate t d Ap 2?;1 Application filed December 24, 1914. Serial No. 878,878.
end of the base 18, or the end adjacent the cutter 17, is provided with a rigid right angular arm 19 having a slot therein intermediate its top and bottom edges and extending for a short, distance from its forward end, this slot being designated at 20 in Fig. 2 and being for the purpose of permitting a clamping member to extend through and beyond the arm 19. The upper face of the arm l9is provided preferably with a gage-plate corresponding with the gageplate on the bar 9. The arm 19 extends at right anglesto the adjacent face of the bar '9 so that these bars form a right angle therebetween and will take and hold in proper position material of right angular configuration at one end. The arms 18 and 19 are connected by a web 22 having guide eyes23 thereon to receive a filler angle block as hereinafter described. The gage itself is adjustable longitudinally of the back bar 9 by means of a threaded block 24 engaging the rotatable screw mounted in the frame of the back and operated'through a suitable hand wheel 26 to move the block 24 and the attached angle bars 1819 l ongi-' the hack, thescale and the bar secured through the hand wheel 26.
The work may be clamped against the I face of the back 9 by means of a clamping bar 27 carried by the base 18 of the gage and movable therewith longitudinally of the back. This bar at its forward end and inneiyedge is provided with a relatively narrow clamping tooth'28. The re'ar portion of the bar extends through a slot in the guide 29 secured to the face of the base 18, being against the back 'adjustably held in said guide with its forward end pressed against the work'seated by means of a friction spring 30 which not only serves topress the finger 28 but also serves to retain the bar 27 in any position to which it is moved longitudinally of the back. The outer edge of the bar 27 is formed with an operating finger 31, which likewise serves as a limiting stop for outward movement of the bar, and
* with a stop lug 32 which engages the guide 29 and prevents the bar being moved too far in the opposite direction so as to retract this forward'end from within the slot 20 of the gage-arm 19. The finger 31 prevents the rear end of the clamping bar from being withdrawn from the adjusting guide. It will be understood, of course, that the friction of the spring 30 holds the clamping bar 1 in longitudinally adjusted position and that the tension of the spring tends to move the forward clamping end of the bar into engagement with the work. By having the forward end 28 of the bar relatively narrow, it is possible to clamp verysmall pieces of material against the bar 9 this type of clamp being employed where the larger clamps are of too great breadth, as for instance in my prior Patent No. 1,114,329, of October 20,1914.
I have heretofore stated that the back may be swung and held at various angles relative to the cutting plane and relative to the edge of the table 5 adjacent the cutter which table edge, in the present instance, is in parallel with the cutting plane. The back and gage may be swung to an angle of 45 and clamped there. Therefore a series of slugs 33 '(Fig. 1) clamped by the bar 27 in the right angle formed by the bars 9? and 19, will have their ends presented at an angle or any other work, it is desirable to trim the opposite ends at precisely reverse angles.
With prior constructions the beveled ends of alined slugs could not engage the bar and at the'same time rest against and in par allel withthe back 9 so as to present their untrimmed edges to the cutter at this reverse angle. I have provided an-angle fillerblock which may be moved into and out of Frequently in constructing boxes,
position and with which the-previously bev- V eled ends. of the trimmed slugs will 006p crate instead of with the gage-bar 19. Such w a filler-block is shown in the drawings,
wherein a block 34 is provided having one edge 35 of a bevel corresponding to the bevel of out, say 45, and this bevel. forming with an adj acent'edge an angle of 45. The block 34 is formed wi an attached shank 37 which slides and also swivels in theguide .eyes 23 of the gage; The block 34 therefore may be swung in th an offset arm 36 having against the gage-bar 19, as shown in Fig.
3, and slugs 33 withtheir edges beveled to a reverse angle to the angle 35 of the-block may be held against the straight edge 38 of the block (which is parallel with the cutting plane) and against the bar inclined at" the proper angles They will therefore have their untrimmed ends. pre- 9 which is sented at a reverse 45 angle to the cutter so that these ends may be trimmed at the reverse angle to the previously trimmed ends, V
the gage being adjusted upon the base to provide the requisite length. This block 34 is slotted intermediate its topand bottom as at 39 in Fig. 6 so that whenit is usedthe forward clamping end of the bar 27 may be projected therethrough and may engage and hold the material,as indicated in Fig. 3 of the drawings. The filler-block 34 with its swiveling spindle 37 may be readily removed from the eyes 23 so that in the event the table is adaptedto hold the back at a plurality of diiferentangles, a plurality of such filler-blocks may be provided with their sides beveled to corresponding angles. The.
ends-of the material may be beveled at the I same angle and not reversed, if desired.
