RICHARD H. GARDNER AND JOHN l'V. GARDNER, OF TROY, NEW YORK.

MACHINE FOR CURLING COLLARS AND CUFFS.

SPECIFICATION forming part of Letters Patent No. 242,295, dated May 31, 1881,

Application filed April 52, 1860 (No model.)

To all whom it may concern:

Be it known that we, Brennan H. GARDNER and J. VVRIGH'L GARDNER, of the city of Troy, county of Rensselaer, and State of New York, have jointly in ven ted a new and useful Im provement in Machines forOurlingOollars and Cuffs, of which the following is a specification.

Our invention relates to such devices as are constructed to curl up from a flat form apparel collars and cuffs after they have been laundered and ironed, the object being to shape them so that they can be packaged in a form which is adapted to that part of the person to which they are applied when worn.

Accompanying this specification, and forming a part of it, are three plates of drawings, each plate containing one figure in illustration, Figure 1 showing, in perspective, a view of a cuff and collar curling device containing our invention, taken so as to illustrate the connections made at one of its ends for receiving and transmitting power to actuate its co-operatin g parts. Fig. 2 illustrates a vertical section of the same machine, taken at right angles to the engaging surfaces of the two rollers, which, by their revolving contact, as arranged, curl up the articles passed between them. Fig. 3 illustrates another view, in perspective, of the same machine, taken so as to show the end of the latter which is opposite to that indicated in Fig. 1.

In all of the illustrations the same letter-references indicate the same parts, and these are designated and described as follows:

At A there is shown an elastic roller, having its shaft-bearings in the framestandards L L, and as designated at S.

At A there is illustrated a non-elastic roller, made of metal, and as having its journals at S S in the adjustable boxes at d, with the latter constructed so that they can be moved up or down between the standards P P by means of guide-flanges O O O O.

In thetop of them-aehine-frame, and connecting with the standards 1 P, are arranged the set-screw plates 00 00, attached at a a, and containin g, by means ofa centrally-located threaded connection, the set-screws T 'l, and so arranged that when the latter are screwed down in their threaded plates the points of the screws will engage with the boxes (1 d, in which the bearings of the metallic roller are placed, and

thus force down the face of the latter against the yielding surface of the elastic roller, so as to produce at their point of contact a slight depression in the face of the elastic roller, as shown at L, Fig. 2, and this depression will be increased in depth by the intervening thickness of the material being curled. To allow this vertical adjustment of the bearing of the metallic roller-shaft the gear-wheel from which it receives motion axially fits loosely into the teeth of the one upon the metallic roller, so as to permit a slight vertical variation of the shaft of the latter without interfering with its geared connection, from which actuating-power is derived. As the surfaces of the two rollers engage thus impressed, the depression produced in the exterior of the elastic roller will only continue at their point of revolving contact, for the elasticity of the material of which the latter roller is made will cause its return in surface extension to conform to the usual circumference of it, when the point of impressed contact in it is passed by the revolution of the rollers.

AtB there is shown a guide-roller, arranged to turn in mandrel-bearings formed on the cranks b I), and the latter having journals and clutching-nuts on the machine-frame, atDD, by means of which the guide-roller is constructed to swing down when not used, as shown in the position designated by the dotted line B. When used the guide-roller is placed as designated at B, and the collars or culfs are fed into the machine over its top, as indicated at Y, by the passing cuff C O.

At S there is indicated the driving-shaft,

and which is provided with the gear-wheel F,

and upon which shaft there is attached a pulley, instead of the hand-crank a, when the machine is to be actuated by power. This geared wheel F, by means of the intermediate pinion F and shaft 5", aot-uates the metallic roller-shaft S and the same driving-- shaft S, by means of the pinion E upon its end opposite the pulley, and as shown in Fig. 3, and the connecting geared wheel E actuates the roller-shaft S of the elastic roller A. The letter K is placed to indicate the machineplatform, and the letters L L to designate the vertical supports of the device.

As the curling eifeet upon the material treated by the machine is produced by the impressed contact made between the adjustable metallic roller and the elastic roller and their opposite axial revolution, the effect will be the same whether one of these rollers actuated the other by their impressed traction, or both had intermediately-arranged geared connection to actuate the rollers, as shown, and the effect of the impressed contact will be the same, so far as the metallic roller and the elastic roller are concerned, when actuated to revolve in opposite axial revolution, whether the impressed contact between the rollers is produced by means of the set-screws or by weighting the ends of the metallic roller-shaft by means of rods and strapped bearings for its journals.

The elastic roller is provided with a metallic shaft and journals, and it may be made of rubber or other similar substance having suitable conditions of elasticity, and such as will allow it to yield enough upon its surface to form a slight indentation or depression where the nonelastic or metallic roller is forced down against its exterior, and which will by its elasticity return to its usual circumferential surface after having passed the pressure contact.

While we have described the non-elastic roller as made of metal, we do not desire to limit our invention to the use of the latter material, for wood or any similar substance harder than rubber or the m aterialof which the elastic roller is made, and which by its impressed contact will form a depression in the surface of the latter at the point ofcontact, will answer the same purpose.

We are well aware that an endless belt running upon two guide-rollers and underneath an intermediate roller has been employed to accomplish the same purpose, by passing the articles to be curled between a depression formed in the belt and the intermediate roller. This device differs from ours in the fact that the curling depression we employ is produced in the surface of an elastic roller by its inipressed contact with a non-elastic roller, and no belt is employed.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. In a machine for curling collars and cuffs having an elastic roller and a non-elastic or metallic roller with their surfaces in an impressed contact when revolving, the roller B, to bend or curve the collars or cuffs passing between the curling-rollers before entering between the latter, as shown and described.

2. The combination, with the elastic roller A and non-elastic rollerA, ofthe guide-roller B, arranged to turn in mandrel-bearings formed on cranks and capable of being swung down when not in use, substantially as described.

Signed at Troy, New York, this 30th day of March, A. D. 1880.
