CRIMPINGe-IVIACHINE.
SPECIFICATION forming part Of Letters Patent No. 790,088, dated May 16, 1905.
Application filed July 2'7, 1904. Serial No, 218,338-
To all whom, it may concern: 7
Be it known that I, FREDERICK J. THOMAS, a citizen of the United States, and a resident of Taunton, in the county of Bristol and State of Massachusetts, have invented new and useful Improvements in Crimping-Machines, of which the following is a specification.
My invention relates to machines for crimping metal articles.
In United States Patent No. 7 63,111, dated June 21, 1904:, and granted to William A. Rayment, is shown and described a knife comprising a blade made with a shank having an annular flange near the junction of the shank and blade and a hollow sheet-metal handle having the rim at its inner end turned or crimped over the flange on the shank.
My invention has for its object to provide an improved crimping-machine, and is illustrated as embodied in a machine for use in crimping the inner end of the handle of the knife, shown and described in the patent above noted, over the flange on the shank to unite the parts.
My improved machine comprises a number of crimping wheels or rolls grouped so as to provide between them a pocket to receive and support the article to be crimped. Mechan: ism is provided to rotate the rollsso as to cause the article being crimped also to be rotated, but on an axis of its own, thereby causing the rolls to circumscribe, and thereby turn or crimp, the rim of the handle or other article being operated upon.
In the best form of my invention three rolls are employed, forming a triangular group, so as to pocket and grip between them the article being crimped. One of the three rolls is mounted upon a holder which is yieldingly pressed toward the other two rolls, the latter preferably being carried by a fixed support. Any suitable mechanism to rotate the rolls may be utilized; butI prefer, as herein shown, to drive the two rolls on the fixed support and to let a third yieldingly-supported roll act as an idler and be turned by rotation of the article being operated upon. The article to be operated upon is placed between the three rolls with the rim to be crimped in the same plane with and engaged by the rolls. The machine being started, the two driven rolls rotate the article,which transmits rotary motion to the otherroll, and as the rolls circumscribe the rim thelatter is crimped by the bending action of the rolls thereon.
In the accompanying drawings, Figure 1 is a plan View of a crimping-machine embodying one form of my invention. Fig. 2 is a front view of the machine shown in Fig. 1. Fig. 3 shows the drive for two of the rolls. '60 Fig. A is a section on line 4. A of Fig. 1. Fig. 5 is a plan view of one end of the frame of the machine shown in Fig. 1. Fig. 6 is a detail hereinafter described.
Having reference to the drawings, 1 represents the frame or base of my crimping-machine. Fixed to base 1 are two brackets 2 and 3, in which are journaled two shafts 4: and 5, carrying at their rear ends gears 6 and 7, respectively, both driven by a gear 8, fixed to the hub of a belt-wheel 9, the latter being journaled on a stud 10,proje,cting from bracket 2. At their. front ends shafts 4 and 5 carry,
' crimping-rolls 11 and 12, arranged one above the other in the same vertical plane. Horizontally opposite the space between the two rolls l1 and 12 and in the same plane with the latter is a third crimping-roll 13, fixed to the outer end of an arbor 13, journaled loosely in a holder 14. Holder 14 is mounted to slide on a way 15, providedon base 1, toward and from. rolls 11 and 12 and is engaged by one arm of a bell-crank lever 16, pivoted at 17 to base 1. The other arm of lever 16 carries a weight 18, which acts to yieldingly hold'roll 5 pocket to receive and hold the article to be crimped, as shown at a: in Figs. 2 and 6, and in some-instancesthe article need not be otherwise supported.
The handles of knives, in the manufacture of which this machine is principally intended to be used, are more or less elliptical, as
shown; but the movability of holder 14 on its way 15 and the yielding pressure of lever 16 permit roll 13 to follow the irregularities of the knife or other article as it rotates with the rolls. 4
As herein shown, the rolls are made with annular grooves upon their peripheries to embrace the flange on the shank of the knife shown and described in the patent above noted, and as the knife rotates between the rolls the sides of the grooves turn in or crimp the rim at the end of the handle over the flange and fit it to the flange;
.During the operation of the machine the pressure of the rolls on the article being operated upon caused by weight 18-ean be increased or diminished by the operator, as required, through handle 20, which also serves as a convenient means to shift roll 13 toward and from rolls 11 and 12 to permit of inserting or removing the work.
Of course when the machine is to operate upon articles other than the knife, which is shown for illustrative purposes, the shape of the rolls can be modified as maybe required.
What I claim is 1. A crimping-machine comprising a number of crimping-rolls grouped to pocket and support the article to be operated upon so as to cause it'to be rotated on an axis of its own when the rolls are actuated; a lever connected with one'of said rolls, a weight acting through the lever to yieldingly support the roll connected with said lever, and means to rotate positively one or more of the rolls.
2. A crimping-machine comprising a number of crimping-rolls grouped to pocket and support the article to be operated upon so as to cause it to be rotated on an axis of its own when the.-rolls are actuated; a fixed support on which some of the rolls are mounted; a holder movable toward and from the rolls on the fixed support and carrying another one of said rolls; a lever connected with said holder, a weight acting through the lever to yieldingly force the holder and roll carried thereby toward the rolls on the fixed support, and means to rotate positively one or more of the rolls.
3. A crimping-machine comprising a number of crimping-rolls grouped to pocket and support the artieleto be operatedupon so as to cause it to berotated on an axis of its own when the rolls are actuated a fixed support on which some ofithe-rollsare mounted; aholder movabletoward and from the rolls on .the
operated upon, and means to rotate positively one or more of the rolls.
