POWER DRIVEN MITERING MACHINE FOR PRINTERS 3 Sheets-Sheet 3 Filed Feb. 27, 1928 Patented Mar. 18, 1930 PATENT o FFlcs EDMUND PAUL EHBLINGER, OF JANESVILLE, WISCONSIN POWER-DRIVEN MITERING MACHINE FOR- PRINTERS Application filed February 27, 1S28. Serial No. 257,526.
This invention relates to a power driven mltering machine for printers.
In printing, it is frequently necessary to cut the slugs or spacers with mitered' ends,
so that they can. be accurately fitted in the block of type carried by the chase. This operation is difiicultto accurately perform and consequently it has usually been relatively crude;
This invention is designed to provide a very simple power driven mitering machine especially adapted for printers use, although obviously-it could be used in other capacities, and which is so constructed that the slugsmay be slipped in pairs into position and may be automatically clamped by the machine and quickly cut with mitered ends.
Further objects are to provide a machine in which the cutting is secured by means of a grinding wheel having, a cylindrical face so'that no accurate angular facing isrequired for the grinding wheel, but merely a flat facing.
Further objects are to provide a mitering machine for printers use which is so constructed thatthe machine will automatically grip a plurality of slugs when-theoperating hand lever is moved in one direction, andwhich will rel'easezthe slugsupon completionof the grinding movement so that the utmost speed may be obtained.
7 An embodiment of the invention is shown in the accompanying drawings in which:
Figure: I is a plan View of the entire machine;
Figure 2 is a sectional view on the line 22 of Figure 3;
FigureS-is a sectional view on the'line 33 of Figure 1 Figures is a fragmentary plan view of the lower portion of the mechanism Figure 5' is a perspective view of. one 'of' the slugs showing at one end, in full lines, the bevelled edge produced. by the" machine, and showing in dotted lines at the other end, the corresponding bevel that canib'e produced at the other end of the=slug,-if desired.
Referring to the drawings, it will be seen that the machine comprises a base portion, 1 from-Which rises a supporting arm or bracket 2, such arm projecting laterally of the machine. The base is also provided with a pair of upwardly projecting guides 3' and with a pair of rear spaced pillows 4'. A table top 5 is secured to the rear pillows .4 and to in- 5 wardly projecting lugs 3 (see Figure 3) carried by the uprights or guides '3. This table top is provided with a pair of slug guides 6 which are arranged at right angles to each other, as shown in Figure 1, and which may be formed integrally with the table top, if desired. These guides are adapted to have the slugs 7 held in contact therewith and the bottom of the slugs is adapted to rest upon the table top. 1
The means for cutting away the ends of the slugs to form the bevel, consists of a grinding wheel or other cuttingwheel 8 carried by the shaft 9 of a small electric motor 10. This electric motor is carried by a piv9 otallymounted frame 11. The frame 11 is pivoted upon a pintle pin 12 carried by the arm'2 (see Figures 1 and 2). It is urged upwardly'by means of a spring 13 loosely coiled about a rod 14 pivoted at its lower end to a bracket 15 upon the base. The rod passes loosely through an aperture in the frame 11 and is provided with lock nuts 16 Whichliinit the upward motion of the frame 11 under the action ofthe spring 13. The motoris provided with a base 17 (see Figures 1 and 2) which is dovetailed into guides formed in the pivoted frame 11. It is adjusted towards or from the workby means of the screw 18 (see. Figure 1). The frame 11 is rocked by means of a handle or lever 19 which is pivotally held to the frame 11 by means of the bolt 20. lhe lever projects outwardly from the bolt and carries a pin 21 which rides within an arcuate slot 22 formed in the frame 11 and a'dapted to' limit the rocking .motion of the lever with respect to the frame. 1
The positioning of the slugs is secured by means of a stop 23 which, as may be seen from Figures 1, 2 and 3, is'provided with a f pointed end with the faces of the pointed ends arranged at right angles to' each other and against which the ends of the slugs? are adapted to contact. This guide"23 is provided with: aportion'2 i of dovetail shape,
which fits a corresponding slot formed in a vertically movable crosshead 25 (see Figure It is adjusted by means of the screw 26 (see Figure The c'rosshead is guided by means of the guides 3 previously mentioned, such crosshead and guides being provided with slot and tongue connections. The cross head is provided with a pin 27 (see Figures 2 and 3), the pin fitting within a block 28 carried in a rectangular slot 29 formed in a projecting arm 30 of the frame 11. Normal-' ly, the crosshead isheld in the position shown in the drawing, but it is obvious that when the pivoted frame 11 is depressed by means of the hand lever 11, that the stop 23 will be moved downwardly out of the way of the downwardly moving grinding wheel or cut-.
ting wheel 8.
Means are provided for holding the slugs 7 in contact with the guides 6 formed on the table top. These means comprise a pair of arms 31 (see Figure 1) which are rigidly carried by upright shafts 32 projecting upwardwhen the slide 35 is moved inwardly and,
consequently, to force the arms of gripping dogs 31 into engagement with the slugs 7 (see Figure 1). The slide 35 is moved inwardly by means of the lever 38 (see Figures 3 and 4). This lever 38 is connected to the slide at its lower end and is pivotally mounted intermediate its ends upon a bracket 39 carried by, the base 1. It is adapted to be moved into the position shown in Figures 3 and 4 by means ofthe lever or handle 19. This is accomplished by rocking the handle towards the outer side of the machine (see Figure 1).
The handle contacts in this position with the lever 38 and consequently rocks the lever out wardl'y and forces the slide 35 inwardly. Thisslidecarries a pin 40 (see Figures 3 and V 4) which is adapted to be engaged by the locking pawl 41, such pawl being urged upwardly by means of a leaf spring 42.
Itjis apparent, therefore, that when the operator rocks'the lever or handle 19 outwardly, that 'he clamps the slugs 7. against the guides 6. In order to automatically release the slugs, a downwardly projecting tongue 43 is "carried by'the crosshead 25 (see Figure 3) When the table is depressed, the crosshea d is depressed, as previously described, and the tongue 43 contacts'with the latch or pawl 41 and [thus releases the slide 35/ The tension of the spring 34'and the angular relation of the arms 33 cause the slide to move forwardly and cause the locking dogs 31 (see Figure 1) to release the slugs.
It is apparent, therefore, that in operating the machine, all that is necessary is to position the slugs upon the table 5 and slide them forwardly, until their front edges contact with the stop 23. Thereafter the o erator rocks the handle or lever 19 outwar ly and thus locks the slugs in place. 7 Thereafter, he
depresses" the frame 11 by pressing downwardly upon the handle or lever 19 and causes the cylindrical face of the grinding or cutting wheel 8 to pass over the projecting ends of theslugs and correspondingly bevel them. Upon completion of the downwardmotion, the trip tongue 43 releases the pawl 41 and consequently the dogs 31 move outwardly away from the slugs and release the slugs.
- It is to be noted particularly that the an gularly set guides 6 converge towards a point,
and that the stop 23 hasits pointed end at the point of convergence of the angularly-set guides. Further, it is to be noted particu larly that this stop has its faces set atright angles to each other. The result of this construction is that the machine will automatically take care of any size of width of slugs be very quickly operated even by an unskilled person.
Further, it is to be particularly understood that other types of cutters may be used besides the grinding wheel indicated.
' It is apparent also'that variousmodifications in theprecise manner in which the; de
vice is formed, may be made without departing from the spirit of theinvention, therefore, although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may bevariously embodied and as the scope of such invention is to be determined as claimed. g
