Tb all wh'om it oac m-y ,1
Be it known that I, SAMUEL Loarna, a
citizen of the United States, and a resident of oakianaeoumy of Alameda and State of California, have invented a new and use ful" Corrugating Machine; of which the 'i ol-- lowing is 'a specification.
My invention relates to a corrugating ma-- adapted for corrugating chine, particularly sheet metal. I 1 7 An object of the invention is to provide a sl'ieet-n'ietal corrugating machine which is adapted upon the application of a slight st I my invention which is illustrated in the. drawings accompanying and torming partform within the scope of my fort'to'instantly exert apoweri'ul force on the work or release the application of such force.
Another Object of my invention is to provide a corrugating machine which may be adjusted to maintain any desired relationship between the corrng'ating rolls regardless of their distance apart.
'A further object is to provide a machine of the character described in which the pressure exerted by the rolls on the work may be evenly distributed throughout the length of therolls. v- I a A still further object of my inventionis to provide a machine. of the character describedfin which the relationship between the. corrugating rolls may be entirely controlled through a lever operatable with one hand.
The invention possesses otherobjects and features of advantage, some of which, with the foregoing will be set forth in the following description of the preferred form of of the specification. .It'is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations oi the preferred invention as set forth in the claims.
Referring to -said-drawings:- Figurel' is a side view of the corrugating machine of lily-invention.

7 pressure roll and an adjustable rotatable pressure roll whose shaft is mounted in slidiable bearings. Y A pair of levers in}. crumed on the frame and operatively and adjustablyv connectedat one end to stems attached to said bearings ,-springs being arranged abont'tjhe stems so as to resiliently hold saidlrolls apart; Movem'ent of therolls toward ea'ch other is e fi'ected by means of a hand lever wh ch is fulcrumed' to the frame and is provided with a cam portion .arw ranged to engage a guided ,s'lidable block to which the other ends of said levers are connected; The adjustable roll may beheld positively and locked in various desired po sit'ions. Driving-of the pressure rolls is effected by'fgears which are adapted tov remain in engagement regardless of the 'posi tion of the adjustable roll. 1
A detailed description follows zi The machine of'my invention in its presentembodiment is particularly adapted for corrugating flat sheets of metal or sheets bent-to cylindricalor other forms. 1 As illustrated, the machine comprises vframe 5 having a post 6 fron which upper and lower arms 7 and 8eXtend transversely. Mounted in bearings 10 and 11 carried in the frame between the arms is a pair of shafts 12and 13. The bearings 11 are preferably held fixed in the frame, while the bearings 10 are slidablyheld in guideways 14 to enable the.
Fixed to the movable bearings 10, which bearings it will be noted are disposed at opposite ends of therolls, are vertical studs or stems 18 which extend through and above the :fraine. The rolls are resiliently held apart by meansof springs l9encircling the stems and interposed between the top of the frame and a nut 21v adjustably held on the stem. 1 I 1 Means are provided for causing both stems ,to be simultaneously depressed. Fulcrumed on the frame to swing in a plane parallelto the plane of movement of the roll 15 with respect to roll 16 is a pair of levers 22; one arm 23 of each of which is ie present embodiment of "the invention, engagement between the levers and stems is eflected by means of shoes 24 formed on the arms 23 arranged to rest in recesses 26 formed in nuts 27 which engage the thread ed portion 28 of the stem. It will be noted that the positioningof the nut 27 on the stem determines the effective length of the stem and thus affords an adjustable relationship between the stems and levers. The other arms 29 of the levers are connected to a slidable blotlr or cross-head 31 by means of links 82. The block is guided for move ment corresponding with that of the slidable roll by means of bars 33 fixed to the frame and engaging in suitable bores pro-- vided in the block.
Fulcrumed on the frame is a hand lever 34 onearm of which is in the form of a cam member 36 which is preferably arranged to engage a roller 37 carried on the block 31. Thus, by pulling the lever and elevating the block, motion will be communicated to the stems through the intermediate links '82 and levers against the resistance of the springs 19. By the use of the foregoing construction it will be clearly understood that a slight force applied to the lever handle 38 will cause the instant application of a powerful force to the metal which may be interposed between complementary parts of the rolls.
Means are provided for holding the adjustable roll in any desired position with respect to the fixed roll. as here shown, such means includes a pawl ll carried by the hand lever and arranged to engage a ratchet 42 which is adjustably secured to the movable block. The pawl is preferably associated with a spring 43 which tends to keep the pawl in engagement with the ratchet. T he pawl may be released from the ratchet by suitably pulling on a chain 44 after slightly depressing the hand lever.
Power for rotating the rolls is preferably transmitted through a clutch 46 to a drive gear 47 fixed on the'shaft 13. The motion of the gear 47 is transmitted to a gear 48 fixed on the shaft 12 by means of a pair of idler gears 4:9 and 50 mounted on fixed stub shafts carried on the post 6. The engagement of the gears 4-8 and 4:9 is such as to allow the vertical movement of the gear 48 without destroying their operative engagement. As here shown, the gear 4-8 is arranged to be moved tangentially across the face of the gear 49, so that considerable movement in its path is allowed without getting the gear entirely out of mesh, the movement of the roller shaft 12 relative to the shaft 13 being limited to maintain the meshed relation of the gears.
In the operation of the device, with the rolls suitably separated, the metal to be corrugated is inserted between the rolls. The hand lever is then depressed until the pawl engages in the desired ratchet notch,
the ratchet member having been previously adjusted on the block to afford the desired positioning of the roll 15, thus initially forming the metal immediately between the rolls with the desired corrugation. By then throwing in the clutch, power is applied to rotate the rolls to advance and corrugate the sheet. As soon as the corrugating operation is completed, the pawl may be withdrawn from the ratchet to enable separating of the rolls and removal of the work.
