I TOOL Filed Jan! 9. 1930 757m (VzZhnlzzels A ToR 'EY A Patented July 21, 1931 JOHN ivrrm on minus, or nnmnorr, MICHIGAN swoon Application :filed January 9, 1930 Serial No. 419,542.
This invention relates to improvements in tools consisting of toolholders; and blades therefor, and is primarily intendedforuse in a well known type of automatic machine wherein a toolholder slot is provided inthe slide having its upper margin in alignment with the centre of the work and wherein the slide has no vertical adjustment, though these tools may also be successfully employed on other types and makes of machines.
It is an object of the invention to provide a tool intended for such purposes as necking 0r parting, or both necking and parting simultaneously wherein the blade or blades is/are so arranged in the toolholder that it/they may be readily removed and replaced in the same position in a short space of time by an unskilled operator withoutdisturbing the setting of the toolholder, or having to index the spindle.
Another object of the invention is to provid e a tool wherein the holder has one or more pivotalguides'thereon with blade receiving grooves formed in one side so that when the 7' angle of the guides is varied the inclination of the blades carried by them is changed.
A further object of the invention is toprovide means in such a tool for positively holding the'guides so that the. inclination of the blades cannot be changed by pressure exerted against them by the work. a
With these and other objects and advantages in view which will become apparentas the specification proceeds, the inventionis' hereinafter more fully described with the aid of the accompanying drawings, in which :t
Figure 1 illustrates a side elevation of the tool mounted 1n the Shde O a machme parallel wlth the plate 8, and that in the Figure 2 is a plan view of Figure 1.

Figure 8 is a section on the line 88 of Figure 4. v
Figure 9 is a section on the line 9-9 of Figure 8. p
Since the tool is primarily intended for use in one type of machine, it is shown in Figures 1 and 2 applied thereto and is mounted in a horizontal slot 1 :tormedin one side of a slide 2. The tool itself consists in part of a plate 3 which is adapted to rest against the base of the slot 1. This plate is usually held in position by a substantially U-shaped memher 4 which is forced against its upper and lower margins by a strap 5 supported on studs 6 projecting from the side of the said slide. v
I will now describe the embodiment of the tool shown in Figures 1- to 6 and 8 and 9. Extending laterally from the plate 3 is a hinge pin 7, and pivotallyimounted on the vlatter are guides 8 and 9 between which a spacing block 12 is arrangedthrough which the said pin also projects. Through the guides 8 and 9 apertures 8a and 8b and 9a and 9b are formed for the passage of studs 10 and 11 which'also project laterally from the plate 3 in alignment with the hinge pin 7. The studs are smaller than the guide aperturesthrough which they pass so that limited pivotal movement of the guides is permitted about thevhinge pin. Through the spacing block 12 openings 12a and 12?) are formed which fit snugly around the studs 10 and 11 which extend through them. i
Itwillbe noted thatthe guides 8 and 9 and-thespacing block 12 all lie substantially sides of the guides adjacent the block 12 longitudinal grooves 14 are formed so that blades 15 may be inserted from the ends. To the sides of the guides 8 and!) adjacent the block 12 retaining members 17 are secured longitudinallyunder the grooves 14 and extend upwardly beyond the undersides of the latter, These retaining members rest partly in recesses 18 formed in the sides of the guides so 1 that their outer sides lie substantially flushwith the'guide sides. The blades 15 have heads 16, across which cutting edges are formed, wider than their lower portions on one side of each of which serrations 16a are provided throughout their length. The thickness of the upstanding portions of the retaining members 17 against which the lower portions of the blades 15 rest shouldbe lessthan the amount which the blade heads 18 project laterally beyond their lower portions.
Transversely through the guides 8 and 9 threaded holes 19 are provided for locking screws 20 on the inner ends of which locking members 21 are so secured that the screws may rotate independently of the said members. @n the ends of the said locking members serrations 21a are formed to coact with the blade serrations 16a. In order to hold tli'e said locking members 21 against rotation with the screws 20, so that the serrations 21a will always remain in alignment with the blade serrations 16a, angular slots 19a are formed axially in the sides of the threaded holes 19 to engage the coinersof the locking members 21. Through the plate 3 an aperture 22 is provided to ai'i'ord access to the locking screw 20 in the guide 9. p
By turning either guide 8 or 9 about the hinge pin 7 the inclination of that guide and its blade 15 maybe adjusted. Nuts 25, 26 aiitl 27 on the outer extremities of the hinge pin 7 and studs andll exert pressure transver's'ely against the guide 8 and hold it arid the guide 9 against movement about the said hinge pin. To reinforce this held and positively preteiit rotation of the guides 8 9 and their blades when pressure is eiierted against the latter by the work, iiitli- (rated at A, tapped holes 23 are provided thrbiigh the, said guides at right angles to the axes of their apertures 86! and 9a and ex teiid into the latter. In threaded engagement with the tapped holes 23 are screws 24 the inner ends, of which are adjusted to contact the stud 10 after the. guides have been set at their desired angles.
The purpose of making the spacing block non-pivotal about the hinge pin 7 j is to facilitate separate angular adjustment of the guides 8 and 9. The adjacent sides of the blade heads 16, when securedin pbsitio'n by the lockingmembers 21', are forced intoihti mate contact with the sides of the spacing block 12, so that the thickness of the latter determines the spaciiig between the blades 15 which must be exact whentwo cuts are to be talren simultaneously. It is foi this reason, and to insureth'e use of the spacing blocl: as the determining factor iii spacing the blades, that the width of those pbsitioii's of the retaining members 17 against which the lower portions of the blades 15 rest is made less than the overhang ofthe blade heads 16 beyond the sides of their lower portrons. i v j v The plate 3 may be held in position in its slot 1 by a U-shaped member 1 and strap 5, or in any other preferred means, and the height of the member 4 is such that both the blades 15 may pass under it when being either inserted or removed. Thus it will be seen that the blades are readily accessible and may be removed by loosening the locking screws 2t) and without disturbing the setting of the guides 8 and 9.
It is believed that the construction and operation bf the tool will be readily understood from the foregoing description wherein the method of securing the guides 8 and 9 in position by tightening the nuts 25, 26 and 27 and the screws 24, and of tightening or loosening the blades 15 by turning the looking screws is fully described, The smooth parallel sides of the spacing block 12 which is non-pivotal on the hinge pin 7 permit the adjacent sides or the blades 15 to be easily moved over them as the latter and their guides are being angularly adjusted; and the nonpivetal arrangement or" the block facilities separate setting of the two guides 8 and 9 which are sometimes employed at an angle to one another.
, Referring to the modified construction shown in Figure 7, it may be remarked that a cross sectional view only is shown since Fi tires 1, 4 and 8 would apply equally to the changed structure wherein the spacing block and second guide are eliminated The one and only guide 90 rests against the plate 3 and is similarly pivotal about a hinge pin 7. A similar locking screw 20 and locking member 21 are provided to exert pressure transversely of the blade 15, and, since only one blade is employed in this construction and therefore the distance between blades which is considered in the two blade arrangement is no longer a factor, the retaining member 1.7 a is not only made higher but wider. In this case th'e width of the said member 17a is greater than the overhang of the blade head 16 beyond its adjacent side, so that when the locking screw 20 is tightened the lower portion of the blade 15 is forced into intimate contact with the member 17a, while the latter inturn rests against the adjacent side of the plate 3. This greater bearing surface is provide'd for the blade and this bearing surface is located immediately behind the locking member 21 by which transverse pressure is exerted against it.
Whuein the foregoing. thepreferred embodiments of the invention have been: described and shown, it is understood that these constructions are susceptible to such further alterationsand modifications as fall within the scope of the appended claims.
