which will carry out this work in an accurate,

and expeditious manner.

A further object of the invention is the provision, in a machine of the character specified, of a rotary dial or plate having pockets to which the screw or bolt blanks the heads ofwhich are to be slotted maybe fed either said machine.

automatically or manually, as desired.

A further object of the invention is the provision of improved means for intermittingly rotating the dial-plate or carrier in which the screw-blanks are placed.

A further object of the invention is the provision of means for reciprocating said dialplate or carrier to cause the heads of the blanks carried thereby to be brought into contact with means for forming the slots in said heads.

A further object of the invention is the provision of improved devices for ejecting the blanks after the heads thereof have been slotted by a milling-tool or other suitable form of cutter.

A further object of the invention is the provision of means for ejecting the screw or bolt blanks, said means traveling at a greater rate of speed than the dial-plate or carrier while Like numerals designate similar parts throughout the several views.

Referringtothedrawings,thenumeral5designates the supporting-framework of my improved machine, which in the form represented isin the shape ofa column orpillar, although any other suitable frame maybe employed. Located on the top of this framework is a pan 6, preferably of rectangular form, which may serve as a receptacle for blanks to be fed to the machine or as a catch-pan for cuttings, oil, &c., said pan being bolted to the frame at 7. (See Fig. 1.) Adjustablyseeured to this pan 6 is a head 8, having slots 8 in its lower portion, through which pass bolts 9, and for adjusting said head a screw 10 is provided, which is threaded into the base of the head, as illustrated in Fig. 1, all as will be hereinafter explained. This head is provided with standards 12 and 13, respectively, having bearings 12 13, in which is journaled a shaft 14, carrying a gear-wheel 15 and a belt-pulley Journaled in other bearings 17 17 at the top of head 8 is a shaft 18, carrying a pinion 19 and a stepped pulley 20, and said shaft 18 rotates in a sleeve 21, having a horn 21, with a bearing 22, the latter fitting over the end of shaft 1% and serving to steady and sustain the same against fiexure. Secured to said shaft 14 is a pair of milling cutters or saws 23, spaced apart by a sleeve 24 and adapted to cooperate upon the heads of two bolts or screw-blanks,as will be hereinafter explained.

While milling-cutters are shown for acco mplishing the purpose stated, it is, however, distinctly to be understood that the invention is not limited thereto, for cutters operating in a difierent way may be substituted for those shown without departing from the invention.

Secured to the pan 6 in the illustration given is a sleeve 25, having a flange 26, through which pass bolts 27, as illustrated in Fig. 5, and this sleeve is provided with a lateral offset 25, in which is pivoted a pawl 270, one end of which is normally forced inward by a spring 28. (See Fig. 5.) Fitted for reciprocation within this sleeve 25 is a shaft 29,

and to one extremity of this shaft is secured a dial-plate or carrier 31, having a series of concentric sets of seats or openings 32, preferably bushed, as at 33, for the reception of the bolts, screws, or blanks 34,- the heads of which are to be slotted in the machine. This dial-plate or carrier 31 is preferably provided with a hub 31 and in the illustration given is secured to shaft 29 by a screw 35, passing through the hub, a plate 36, fastened to the dial-plate by screws 36 and a bolt 37, the head of which bears againsta washer 38 upon the plate and the stem of which is threaded into shaft 29, as illustrated in Fig. 5. Adjacent to its lower end shaft 29 is provided with a ratchet 39, the hub 39 of which is sleeved upon said shaft, and normally in contact with this ratchet is the long tail 270 of the pawl 270. Passing through the hub 39 is a screw 40, which is threaded into shaft 29 and the end of which enters a groove 41 in a stem or spindle 41, carrying an antifriction-roller 42.

Journaled in bearings 43 43' of the frame 5 is a shaft 44, provided at one end with a gearwheel 45 and at its opposite extremity with a cam 46, upon which rests the antifrictionroller 42 of the stem 41, connected to the shaft 29, as above described, and mounted in a sleeve 47, projecting from a link 48, pivoted at 49 to the column 5, is a shaft 50, carrying a small gear 51, in mesh with gear 45, and a belt-pulley 52. By journaling shaft 50 in sleeve 47 provision is made for substituting gears 51 of different sizes for the one shown, whereby shaft 44 may be driven at the desired speed, and to permit this to be accomplished the link 48 has a lateral extension 48, slotted at 48 and adjustably secured to the column bya bolt 52. (See dotted lines, Fig.2.)

For intermittingly rotating the shaft 29 by means of the ratchet-wheel 39 I may employ various devices; but in the preferable construction herein illustrated a pull-pawl 53 is provided, the nose of which engages with the teeth of said ratchet-wheel and intermittingly actuates the same. This pawl is located at the end of a bar 54, and for actuating said bar a cam 55, having a laterally-projecting arm or wiper 56, is secured to the shaft 44, said arm or wiper engaging with a lever 57, pivoted to the frame at 57 and having an angular extension 57 which passes between V projections or bearings 58 58, one of which may be a roller on the bar 54 and the other a fixture of the frame, a spring 59 serving to retract the bar after the cam 55 has exerted its influence. As will be obvious, when the cam 55 rocks the lever 57 upon its pivot 57 the angular end 57 of said lever will work between the projections 58 5S and will reciprocate the bar 54 and cause the pawl to engage the teeth of the ratchet-wheel 39 and partially rotate said wheeland the shaftto which it is secured, a spring 59 returning the lever and pawl to their normal positions.

Pivoted to an ear 43 of bearing 43 is a lever 60, preferably of angular form, as represented in Figs. 2 and 6,and to the opposite end of said lever is pivoted at 61 alever 61, having a forwardly-extending portion 61 pivoted at 62 to the sleeve 25 and provided with a depending nose 61 which rests upon the ratchet-wheel 39. Located on the shaft 44- and preferably adjacent to cam 46 is a cam 63, (see Fig. 1,) and this cam operates thelever in a manner hereinafter stated.

Pivoted to one end of lever 61 is a link 64, and this link is in turn articulated to a lever 65, pivoted in a bracket 66, depending from the pan 6. To the long end of lever is jointed a head 67, to which blank-ejectors in the form of pins or plungers 68 68 for discharging the slotted blanks are attached. These ejector enter the openings in the dialplate or carrier 31 and serve to discharge the blanks the heads of which have been slotted by the cutters 23.

Attached to the column 5 below shaft 44 is a pan 69, which serves as a drop or catch pan.

In the operation of my improved machine screw, bolt, or other blanks to be slotted are placed, either manually or automatically, in the seats or openings of the carrier or dialplate 31, and the machine being set in motion shaft 29 is raised by cam 46 to force the carrier upward and cause the heads of two of the blanks to be slotted by the cutters In the vertical movement of the shaft29 the ratchetwheel 39 is carried above the pawl 54-,as shown in Figs. 1 and 6, and in the timing of the machine when two blanks have been slotted the cam 46 has been turned in the direction of the arrow to bring the cut-away portion 46 of its periphery opposite roller 42., thereby permitting shaft 29 to drop and cause the teeth of ratchet-wheel 39 to be brought into line with the nose 53 of the pawl 54, when arm 56 of cam 55 will operate upon lever 57 and cause said lever to actuate the pawl and turn the ratchetwheel 31 and shaft 29, to which the carrier is attached, one step, thereby bringing another pair of blanks beneath the cutters. Stop-pawl 270 prevents back motion of the shaft and attached ratchet-wheel during this action. During the upward movement of shaft 29 the ratchet-wheel 39 will tilt lever 61 upon its pivot 62, thereby through the link 64 and pivoted lever 65 (said parts acting as a compound linkage) forcing upward head 67 and ejeetors 68 63 at a speed faster than the movement of the shaft, whereby the slotted screw-blanks will be ejected before new blanks are forced against the cutters 23. After the blanks have been slotted the shaft 29 drops and cam 63 comes into contact with lever 60 and through the levers and links constituting the compound linkage described pulls downward head 67 positively to withdraw the ejectors 68 68' from the openingsin the dial-plate or carrier 31. These finished blanks when ejected fall into the pan 6, from its bed-plate or pan 6.

which they may be removed in any desired way.

It is importantin machines of the class described that a blank or a set of blanks the head or heads of which have been slotted should be positively ejected before another blank is forced against the cutter, and this is accomplished by the compound linkage described, through which an accelerated speed is given to the ejecting-plungers. Other means may be substituted for accomplishing the result stated, the invention not being limited to the devices illustrated.

It will be observed that provision is made for the reciprocatory and rotary movements of the shaft 29 and itsattached dial-plate or carrier 31 by virtue of the connection of the stem 41 with the shaft by screw 40, said screw passing through the hub of the ratchet-wheel 39 and entering a groove in said stem, as illustrated in Fig. 5.

While the machine is shown as of vertical arrangement, it is distinctly to be understood that the invention is not limited thereto, for many ofits parts could be arranged horizontally or in other positions without departure from the scope thereof.

While two concentric sets of bushed openings are illustrated, yet more than two sets may be employed, or even one set, if deemed necessary, without departure from the invention, and many details of the machine may also be variously modified.

To cushion the blow of the'shaft 29, a washer 7 0 may be fixed to the top of sleeve 25, or other means may be employed for accomplishing this purpose, if desired.

Various sizes of dial-plate or carrier may be substituted for the one shown, and to adjust the head 8 to position the cutters 23*properly over the blanks the bolts 9 are loosened andscrew 10 is turned to move said head upon This pan and also the pan 69 may, however, be omitted without departure from the invention, and the head may be supported in various ways differing from that shown.
