T all whom 'it may concern:
Be it known thatI, DUANE E. E. ROLAND,
. a citizen of the United States, and a resident of Roxborough, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Cutting .Attachment for Tube-Forming Machines, of
. rwhich the followingiis a description.
paper of many plies to produce so-called My invention. relates to that type of niachines in which tubes are .formed ot heavy fiber-board tubing to be ,subsequently made into drums or barrels by the addition of atcached heads and bottoms and the application of hoops. The tubes are formed by wrapping the material in4 successive layers on a steel cylinder, the layers being glued to one another. The tubing is formed continuously by the machine 4referred to and as it moves forwardly it is siowly revolved. At present the formed tubing passes to a part of the machine for the second or cutting operation by which the tube is cut into longT lengths, usually about seventy-two 'inches long and these pieces are then carried along for the third operation which cuts the pieces up into the desired lengths, twelve, fifteen or twenty-four inches in length for example.
llIy invention particularly-relates to the second operation or cutting of the tubes into long lengths in the machine in question, the operation now being entirely manually controlled, the object of my invention being to.'
perform the operation largely automatically.
The nature of the invention, its distinctive features and advantages can best be stated in coniiectioii.\\'ith the specific description ot a practical embodiment ot the invention'as hereinafter g'iv'en.
Reference is to be-liad to the. accompanying drawings forming a part otthis speciiication, it being understood that the drawings are' merely. illustrative'of one example of the invention.

Figui-e 8 is av diagraminatical view of a circuit that may be employed.
In the illustrated example, A represents a machine bed having track rails l5 at the.
sides, and C indicates a tube requiring to be cut into lengths. A carriage here designated generally by the numeral l() is provided with axles 11 `having wheels 12 ruiining on the rails At one side said carriage has upwardly extending biackcts 13 to` which arms 14 aie secured by bolts 14d,
said arms carrying a presser roller 15 to bear against the tube C at one side at the Y,
top. On the carriage 10 at the opposite side from the ioller 15, the saw 16 for cutting the tube into lengths is located and is mounted upon a mandrel 1T turning in bearings 18,
on a bracket or Jframe 19 having hubs or fixed bearings 20 fixedly secured to a longitudinal shaft 2l turning in bearings 22, 23 on standards 24, 25, said standards providing bearings 2G for the axles 11 of wheels 12 and provided with stud arides 27 ior` wheels 28, running at the under side ot' the track rails B. The sha'tt 21 has fixed thereto the-hub 2S) of a handle 3() for manually swinging ot the saw toward or from theI tube C when desired, rocking the shat't 21 in the bearings 22, 23. Un the carriage outside ot' the saw a lstop means is provided to limit the outward swinging ot' the movenient ot the saw and its frame. For the purpose in the illustrated example an upwardly extending member 31 is provided on one oi' the bearings as 22 and is provided with a set screw 32 adjustable to variously limit. the outward swinging movement permitted the saw Jframe. The arrangement of the carriage and saw is such that when the saw isswung inwardly to the tube C (which the tube, the saw and tube at the same time revolving'ainl in accordance with my invention, the saw having completely severed the tube the carriage is automatically arrested, the arresting of t-he saw thereupon, permitting the overbalanced saw frame with the saw to swing laterally outward away from the tube. The carriage, in accordance with the illustrated form ot' my invention, is manually returned to its original position by the attendant, all the other operations/oi' the carriage and saw being automatic, means being provided to automatically swing the saw frame inwardly to the sawing position. In `the present linstance electromagnetic means in circuit with an automatic circuit closer and a circuit breaker serves to swing the saw laterally inward, the illustrated means for the mentioned purpose being as next described.
The automatically operated circuit closer, designated generally by the numeral 40, and shown in detail in Figures 6 and 7 is operated to close the circuit by the advancing end of the tube Chaud. the automatic circuit breaker designated generally by the numeral 60 is operated to break the circuit by the action of the advancing carriage 10, said circuit breaker being so positioned as to cause disengagement of the cutter only after the severing of the tube is completed. On the carriage is an electro-magnetic device, here shown as a solenoid 337 the. core of which is connected as by a short cable or other flexible element 34 with the saw frame 19 and a conductor wire 35 runs from said solenoid to the circuit closer 40, the conductor 36 running from said circuit closer to circuit breaker 60, the latter being connected by a conductor wire 37 with the solenoid 33. A manually operable switch 38 is included in one of the conductor wires. The circuit closer 4() as illustrated includes an insulating base 41 to which is secured by bolts 43 or the like.` yoke-like clamps 42 ot' U-shape having a` clamp screw 44, said yokes extending beneath a rail 45 along which the circuit closer is adjustable. the screws 44 serving to.secure it in. adjusted position. The odset upper end 411 of base 41 presents members at a}')proximately right angles, the one having rigid therewith the metallic base 46 oi a switch blade 50 pivoted to said base 46 as at 49. A binding ,screw 47 serves to secure a short conductor strip 48 running from the base 46 and is adapted to secure also the conductor wire 36. The blade 50 is adapted to engage ber through ywhich a. binding screw 5'2 passes for securing the conductor wire 35. A retractile 'spring 4l. and to switch blade 50 and normally tends to maintain the blade out ol' engagement with the clip 51 and therefore with the circuit broken.
a switch clip 51 on the; base 41, said clip having a conductor mem#y 54 is secured to the base.v
A switch handle 55 ise'- cured by an insulating Ablock '56 to the blade 50, said block being suitably secured as by screws 57 to, the handle and' secured by screws or bolts 59 to the laterally offset upper end 54S of blade 50.. The handle 55 may be operated manually should occasion require it and it lies in the path of the tube C to be engaged and tripped by the latter by moving the switch blade 50 into clip 51 and closing the circuit.
The circuit. breaker 60. includes a fiber base 6l to whichl is secured by bolts 63 or the like a plate 62 which serves to clamp the base to a longitudinal rail 64 for permitting adjustment of the circuit closer to a proper point along said rail, a set screw 65 serving to secure the circuit closer in adliusted position. The main switch blade 66 is pivotally secured to its relatively lixed hase part 68, havingl a. conductor piece 68a through which a binding senew 68b passes into the liber base 61 for securing the conductor wire 36. A secondary switch blade 69 is pivotally secured to the blade" 66 by plate 70, secured at one end as'by a rivet or auxiliary blade. Said blades -are adapted to engage a contact clip 73 secured to the base 61. a conductor piece` 75 running from said clip to a binding post 76 that secures the conductor wire 37. A spring 74 connects the main and auxiliary switch blades to disengage the auxiliary blade from the clip 73 without. sparking. The main blade 66 is provided with a handle 77 secured* thereto by an insulatingblock 78 which is bolted as at 79 to said handle and bolted as at 80 to said blade. A spring 81 secured at its respective end's to the ber base 61 and to which handle 77 normally tends to maintain the switch closed. The saw driven by any suitable means for revolving the saw, there being shown a belt pulley 17"l thereon, over which the belt 17b runs from an elongated pulley 17c on the motor shaft 17 on the machine frame, the arrangement permitting the saw frame. to swing laterally onV the shaft 21 without interference with the belt drive. y c
With the described arrangement, the cir-v cuit closer 40 having been vsecured in a position at thev proper pointalong its rail 45 and the circuitbreaker 6() havingy been. secured'in the proper position along :its rail 6 4,- in the operation of the tube-forming machine as the' forward endet/the tube C reaches lthe trip handle 55, the latter will be engaged by said tube and the switch blade 50 moved on its pivot 49 against the tension ot the spring 54 and into the clip 5l, thereby closing the circuit and thus energizingthe solenoid which causes the saw frame 19 and the saw to be swung laterally inward. As the saw cuts into the tube C the `forward Sliaabi'y bolt 71, and secured by a. pivot 72 to saidarbor 17 isv lso ' severed by the saw, the carriage will -to normally maintain a position with the saw out of engagement with the tube C and therefore upon the solenoid being de-energize'd, the saw frame will rock and will withdraw the saw from the tube and automatically assume the outer position. The severed length of tube is manually removed and the carriage is then moved manually by the attendant to its original position for another forward and cutting movement when the circuit is again closed by the end of the tube acting on the circuit closer 40.' The saw frame 19 may be balanced suitably as ,sufficient tendency to move it forward to counter-act the traction of the carriage on the tracks B, therebeing provided for the purpose in the illustrated example a weight 83 suspended on a cable or other :flexible element 84 sccuredhtethe carriage. i
I would here explain that in the operation of the tube-forming machine as now constructed, the manual thro-wing of the saw into or out of action results in a waste of material due to the lack of precision in determining the successive operations of the saw, so that when the tube is finally cut into the desired lengths for the makingiof the barrels, short ends are produced and the loss constitutes an important item of cost inthe manufacture. This loss is wholly eliminated by the use of my invention because the initial cutting of the tube into lengths of for example, seventy-two inches, is with precision, so that the severed length will cut exactly into a given number of shorter lengths suitable for the barrels and without any short pieces of tube remaining. The positions of the circuit closer 40 and circuit breaker C() can be accurately determined so that the saw will bethrown into actionunfailngly at the proper time and thrown out of action instantly when the tube has been severedv The trip member on the carriage 10 for engaging the trip handle 7 7 of the circuit breaker 60 may consist of a projection 108. The arms 14' carrying the presser roller 15 may be adjusted laterally abouttheir pivot bolts 15, said arms at the lower ends having members 14 formed with slots 141 to receive adjusting bolts 14, as best seen in Figure 3.
I would state in'conclusion that whlle the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the mechanical ldetails herein illustrated, since manifestly the same canbe considerably varied without departur from the spirit of the invention as defined in the appended claims.
Having thus described my invention, I claim:
1. In a machine in which material to be severed is given longitudinal movement; a
