To all whom it may concern Be it known that I, Mosns OWEN, a citizen of the United States, residing at West- 1nont, -Johnston-n,- in the. county of Cambria and State of Pennsylvania, have invented 'certain new. and useful Improvements in ciency of tools of this character; to reduce danger of derangement or breakage to the minimum; to provide for ready repairs when the necessity for such arises; and to adapt the tool for rapidly cutting off bar metals of any contour in cross-section.

With the above and other objects in view, as will appear as the nature of the invention is better understood, the same consists in the novel construction and arrangement of parts of a cuttii'ig-olf tool, as will be hereinafter fully described and claimed.

In the accompanying drawings forming part of this specification and in which like numerals of reference indicate corresponding parts: a

Figure 1 is a face view of the tool;

Fig. 2 is a side elevation, partly in section;

Figs. 3 and 4: are detail views of one of the tool holders;

Fig. 5 is a detail view in side elevation of the head or body of the tool;

Fig. 6 is a detail view of one of the tool holder actuating screws;

Fig. 7 is a detail of one of the parts of the tool,

Referring to the drawings, the numeral 1 designates the body or head of the tool,

which is a solid plate of metal of circular form, and has a portion of its periphery reduced to provide an annular guide '2, and a circumferential flange 3. The body has a centrally disposed bore or opening 4: to receive the bar to be cut, and radiating from this opening are four lateral tubular guideways 5 disposed at right angles to each other and extending entirely through the body, each guideway being provided with a longitudinal all-through slot 6 continued throughout its length, and the outer end of each Elpecification'of Letters Patent.

guideway being formed with a socket or.

' outer face being provided with a channel 11 to receive the cutter C. The other jaw 12 which is secured to the jaw by bolts 13, carries clamping bolts 14 which serve to secure the cutter in place. The threaded bore 15 of the nut 8 is engaged by the screw 16 of the tool holder actuator, shown in detail in Fig. 6. The intermediate portion of the actuator carries a fixed collar 17 to engage the counterbore 7, beyond which collar is a cylindrical extension 18 provided with a key-way 19 and terminating in a reduced threaded extension 20. The outer face of the collar 17 is engaged by a cap 21 having cars 22 and a central opening 23 to receive the extension 18, the opening being surrounded by a boss 24: that also engages the counterbore 7, bolts 25 engaging the ears 22,'serving to secure the cap in place, and thus hold the actuator from retrograde movement.

Keyed to the extension 18 is a bevel pinion 26 which is held against danger of working loose by a washer 27 and a nut 28. Three of the actuators and pinions are identically the same, but the fourth actuator 29 is extended any desired distance beyond the body and constitutes the driving member as it receives the power from any suitable source to drive the three remaining gears and actuators. The gear 30 of the driving member is additionally secured thereto by a pin 31, otherwise it is the same as the pinions 26.

Mounted to rotate upon the guide 2 and held thereon by the flange 3, is a ring gear 32 that meshes with the pinions 26 and 30 and imparts rotary motion thereto and thence to the tool holders, all of the latter being actuated in unison and at the same rate of speed.

In practice the head or body will be firmly secured to'a fixed part of a lathe or the like V t isto he understood. that more thanone g- 21f tao r'vmaybs'emp y ds0110 ma chine; and also "tha'tfsuita ble reversing gear may b'e'usecl to" brlng'the tool "holders back to the starting point, and as these aclclitlonal mechanisms Wlll be readily understood, illustrationthereof is deemed unnecessaryi Having thus 1.- A cutting tool comprising 7 a stationary head having a plurality of radially disposed screws journalecl in the-caps and passing through the nuts, pinions' carried 1 by 'the screWs',a11cl a; ring'gear engaging thelpine iOHStO'ImPEt-It rotary motion tonall ofthe pinions.
