Application sied necember ei, 192i. serial No. 525,131.
To @v -ZZ whom it may concern: Y
.Be it known that LTVILLLAM WV. Vosrnn, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Chio, have' made an Invention Ap- Vpertaining to` Pipe-Cutting Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art 'to which it appertainst-o make and use the same, reference being had to the .accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
This invention relates particularly to pipe cutting machines and has for its object the provision of a simple,lstrong and inexpensivemachine of this character `of novel Vconstruction and operable to ycut a pipe in two in an easy, rapid and eiiicient manner.
The invention is fully described in the folf lowing specification, andgwhile in its broader aspect it is capable of embodiment in numerous forms, a. preferred embodiment thereof is illustrated in the accompanying drawings, in which,-V f.
Fig. 1 is a .side elevation of a machine embodying the invention with a. pipe held in cutting position therein. Fig. 2 is a section on the line 2-2 in Fig. 1, and Fig. 3 is'a section on the line 3-3 in Fig. 1, with 1 portion broken away.;
.Referring to the drawings, 1 designates the base member of the machine, which member is of hollow form and has a standard 2 rigidly rising from each end thereof. The standards 2 are rigidly connectedat their upper ends inspacedrelation to the base 1 by a cross-arm or frame-head 3.
A hollow cross-head Lfwconnects and is guided by the standard forvertical reciprocatory movements between the base and top framemembers; 'A screw 5'is connected at its lower end tothe top of the cross-i.
head 4 for free rotaryV movenientsrelative thereto and extends-upward :therefrom through a hand-wheel 6, being threaded through the hub yof-such wheeh-'which hub is mounted in the frame-head 3ffor rotary, 'but not axial, movements relative thereto, so that a turning Vof the wheel will impart vertical adjustment tothe screw and..cross head.
A pair of rolls k7 Ais suitably mounted on shafts 8 in transversely spaced :relation ic-v Vtween the sides of the base member 1, with their axes transverse to such sides, and a similar pair of rolls9 are suitably mounted on shafts 10, intransversely spaced relation between .the sides of the cross-head 4 in parallel' relation to the rollsand-'disposed in position to cooperate withv the rolls? to grip therebetween a pipe .ori other circular work-piece 11. One of the rolls of the upper set, in the'present instance, is provided with a scoring edge 12-at one end thereof, which is .adapted to bite l a workpiece toV prevent longitudinal movement thereof when rotated'. It is evident that an adjustment of the spacing between the upi per and lower sets of rolls to accommodate work of different sizes and to facilitate the soY engagingv and-releasing of a work-piece is i accomplished by a raising and lowering of the cross-headst.
A drive shaft 13 is mounted at one end of the machine in a bearing arm 14e-which is pivotallyconnected to the base-frame 1 at V15 for swinging movements in a vertical planewith respect to the frame, whereby the shaft 13 may be moved inward ory outward withrelation `to the rollers 7 and y9. The bearing arm 1K4: is connected. bya link 16 to the cross-head 4:, as-for instance, to. an end of one of the shafts 10 thereof so'thata raising ofthe cross-head with .respect tothe base 1.will draw the bearing arin inward, and a loweringof the cross-head'willy force the bearing armioutward. The shaft 13 carries a sprocket-wheel-17 and this is connected by a chain 18 to a sprocket-wheel 19. on the adjacent end of each roll 7 and 9.,.the chain passing .over the sprocket-wheels ofthe up? per set of rolls and down and under the sprocket-wheels ofthelower set of rolls. The
lower flight of the chain is held in engage ment with one of the sprocket-wheels 19 of the lower roll Vset by an idler wheel 2O.V One end of the drive shaft 13 is shown as squared to receive Va crank for hand turning,` or if desired, it may be connected to any suitable motive power. Itis evidentthat Vif the crossehain 13 laterally from ithe machine it willjbe shortened accordingly and it is for this purpose that the bearing arm le forthe shaft 13 is its sprocket-wheel -17- are automatically adheads: is raised the length of projection of the Y' j usted tof compensate for any relative adjustment of the upper and lower sets ofv rolls.
The cutting element of the machine con prisesfa blade, die or other cutting member 2l, which is carried by a vertically adjustable arm 22 in position for the nose of the cutting member to peripherally engage the work in such manner that it will cut therein when the work is turned bythe driving action of the rolls 7 and 9. The arm 22 is pivotally mounted at one side of the cross-head i on a stud 23 projecting from one end portion of the cross-head so that the arm pivot will have vertical movements with the crosshead. The other end of the arm 22 is provided with a segmental rack 24 'which isv engaged by a vertically disposed worm 25, the shaft of which is mounted in a bea-ring 26 secured to a side of the cross-head 4; at the opposite end thereof tothe pivot stud 23. The worm shaft has a hand wheel 27 at the upper end thereof and it is evident that a turning of the worm will effect a vertical swinging' adjustment of the cutter arm 22, The cutting member 2l is adj ustably held to the arm 22 at the linner side thereof byl a bolt 28, or in any other suitable manner.
Itis evident that I have provided a simple and eflicient cutting-olf means for pipes or other cylindrical objects; that it may be easily and quickly adjusted to engage work of'd'ifferent diameters; that the driving chain for the work engaging and'rotating rolls is automatically adjusted during an adjustment of the rolls for different sizes of work soas to compensate for the relative adjustmen-t of the rolls with respect to they driving means,and that the cutting element is easily adjustable to vary the depth of cut and to suit they size of the work.
I wish it understood thatv my invention is not limited to any speciiic construction, arrangement or form of the/parts, as it is capable of numerous modifications and cha-ngewithout departing from the spirit 'of the claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is,-
