This invention relates to machinery for marking or printing hosiery or other articles, by transferring the desired markings from a strip of paper or other sheet material to the articles to be marked.
Generally stated, the object of the invention is to provide a novel and improved construction and arrangement whereby the hosiery or other articles to be marked may be caused to pass l successively through a machine that will automatically transfer the desired marking from a strip of paper to the hosiery or other articles, in a manner that will obviate the necessity of any hand work, in the transfer of the markings from the paper to the stockings or other articles, even though heat may be required to make the transfer effective, the hand work required being that which is necessary for the proper positioning of the stockings or other articles on the machine.
It is also an object to provide certain details and features of construction and combinations tending to increase the general efficiency and desirability of a machine of this kind for transferring wax or other desired markings from paper to the goods or articles to be marked.
To the foregoing and other useful ends, the invention consists in matters hereinafter set forth and claimed and shown in the accompanying drawings, in whi'ch Fig. 1 is a side elevation of a transfer machine for placing the desired markings on stockings or other articles, embodying the principles of the invention.
Fig. 2 is an enlarged detail perspective View of certain portions of said machine.
Fig. 3 is a perspective of one of the stockings, showing the manner in which the same is folded for placing on the machine.
Fig. 4 is an enlarged transverse section on line 4-4 in Fig. 1 of the drawings.
Fig. 5 is a detail section on line 55 in Fig. 4 of the drawings.
Fig. 6 is a similar view on line 6--6 in Fig. 4 of the drawings.
Fig. 7 is a similar view on line 'l-J in Fig. 4 of the drawings.
Fig. 8 is an enlarged detail section on line 88 in Fig. 7 of the drawings.
As thus illustrated, the invention comprises a machine body I provided at its top with a horizontal table 2, and provided at its ends with rollers E: and 4, which are preferably adjustable toward and away from each other, and upon which rollers a conveyor belt 5 is supported. In this way, the upper portion of the belt 5 is adapted to rest on the table 2, and is adapted to serve as a support for the folded stockings 6, shown in Fig. 2 of the drawings, each stocking having been folded as indicated in Fig. 3 of the drawings. The table 2 may have spacing marks I thereon to indicate the positions of the stockings.
A strip of paper 8, upon the lower surface of which the wax transfers are carried, or other impressions or markings, is arranged to travel over sheaves 9, l!) and l I, and around the rotary feed roller l2 and the idler l3, from the roll l4 upon which the supply of paper is carried. As fast as the transfers are removed and placed on the stockings, the waste paper is collected on the roll I5, the latter being the feed roll that pulls the paper along crosswise of the conveyor belt 5 previously mentioned.
In order to transfer the wax markings from the paper to the stockings, a presser plate i6 is provided, immediately above the conveyor belt 5, containing an electrical heating element, and by means of a flexible cord I1 current is supplied to said element to keep the plate heated to the desired temperature. This plate I6 is carried on the lower end of a rod 18 that is. movable up and down in the bearing is, which latter is adjustable horizontally on the supporting arm 20, and a spring 2| is interposed between the lower end of the bearing 19 and the top of the presser plate, and when the arm 2!) moves downwardly, the said spring provides the presser plate I5 with a yielding pressure on the paper 8, sufficient to press the latter against the stocking 6 on the conveyor belt 5, so that the wax impression will be transferred from the paper to the stocking, in the desired manner.
For the driving of the machine, an electric motor 22 is provided and connected by a belt 23, at whatever ratio is desired, with the longitudinal shaft 24, which latter is connected by the worm gearing 25 with the transverse shaft 26, upon the axisof which latter roller 21 is mounted to cooperate with the idler roll 28 for gripping and feeding the lower portion of the conveyor belt 5, as indicated in Figs. 1 and 4 of the draw ings. To intermittently rotate the roller 27, the shaft 26 is provided with a plate 29 upon which, a lever or dog 36 is pivoted, and provided with a roller 3! for engaging the stationary cam 32, as shown more clearly in Figs. 5 and 6 of the drawings. The shaft 33 for the roller 21 is, as previously indicated, disposed in alignment with the shaft 25, and this shaft 33 is provided with a ratchet or clutch plate 35 having notches 35 for engagement with the dog or detent 30, previous- 1y mentioned. Thus, the continuous rotation of the shaft 26, by the motor 22, through the worm gear 25, will cause intermittent rotation of the shaft 33 and the rolier 21 because of the disengagement of the dog or detent 3% from one of the notches 35 each time the roller 31 engages the cam 32 previously mentioned. In this way, the belt 5 is stationary each time the presser plate H5 is moved downwardly to transfer an impression from the paper to the next stocking.
To operate the arm 26 up and down, in timed relation to the intermittent feeding motion of the belt 5, the cam 29 is properly shaped to engage the roller 3% on the vertically disposed bar 37?, which latter is movable up and down in the bearings 38 and 39, there being a spring 49, as shown in Fig. 4 of the drawings, to cause the upward movement of the bar 3?, and the consequent upward movement of the plate It away from the paper strip.
To provide an intermittent feeding movement of the paper strip 8, the shaft t! of the roller l2, previously mentioned, is provided with a pinion 42 for engagement with the vertically disposed rack 43, which latter is suitably mounted in the body of the machine to slide up and down, with a coil spring 4' 1 suitably arranged to move the rack 43 downward, and with adjusting means 45 to adjust the tension of said spring, as well as the stroke of the rack thereby to adjust the feeding stroke of the paper strip 3 under the heated pressure plate. The lower end of the rack 43 is disposed in position to engage the cam 45 on the shaft 26, so that the rack 3 is moved up wardly by this and then moved downwardly by the spring M previously mentioned. The shaft 4! and the shaft M of the roll l5 are connected together by a coil spring driving belt 48, so that the paper 8 will be given an intermittent feeding motion in properly timed relation with the presser plate l6 and the conveyor belt 5, so that each time the presser plate It moves downwardly, a wax impression on the paper will be held stationary below the presser plate, while the stocking or other article is also being held stationary by the conveyor belt and the pressure exerted by said plate will cause the belt 5 to rest on the table 2, so that the desired necessary pressure may be exerted upon the stocking or other article. If desired, the periphery of the roll 52 may be provided with small, sharp points to engage the paper strip 8, to properly feed the latter. To permit the rack 53 to move downwardly, without rotating the shaft M backward, the ball or roller clutch device t9, shown in Fig. 8 of the drawings, may be interposed between the shaft 6! and the roller I2, whereby the roller will be rotated when the rack 43 moves upwardly, but will not be rotated when the spring 4 moves the rack downwardly.
Thus, the invention provides means for practically automatically, by simple machinery, transferring wax impressions or markings from a strip of paper to stockings or other articles, by means of a heated presser plate, thus obviating the necessity of any hand work in the marking of the stockings or other articles. Of course, the stockings must be placed by hand on the conveyor belt, but there is no hand work involved in the transfer of the wax impressions from the lower surface of the paper to the stockings or other articles. Previously, this work was done by hand, by using an ordinary flat iron, or hand iron, of suitable character, but this hand work is eliminated by the use of the machine, as shown and described.
The machine shown and described is illustrative of one form of the invention and it will be understood that while the transfers are shown as being fed transversely of the conveyor belt upon which the stockings are carried, it is obvious that the transfers can be fed or supplied in any suitable or desired manner, without departing from the spirit of the invention.
It will be seen that the casting or machine body I, together with the plate H5 and the various belt and strip feeding instrumentalities, constitute a structural machine unit distinct from the table 2, which latter with its feed rolls 3 and 4 and belt 5 and legs 5!] constitutes another structural unit. Preferably, as shown, the machine unit body i is supported by the under frame 5| of the table unit. By employing the two units in this manner advantages are obtained in connection with the construction and assembly of the machine, as well as in the use thereof. With the strip 6 provided with a separate and independent feed, the impressions thereon can be closer together than are the stocking or articles 8 on the feed belt 5, and thus a saving in paper, from which the said strip is usually made is accomplished, as compared with what would be the case if the impressions were spaced apart the same distance as the stockings or other articles. The belt 5 rests on the top surface of the table 2, with enough of the latter left exposed for use by the workers in folding and removing the hosiery or other articles. In this way the hosiery or other articles can be spaced apart the desired distance, and the length of the table and belt are such that a plurality of said articles can be approaching the strip and the plate 5 I 6, when the machine is in operation, and the stamped articles can be removed from the belt to the surface of the table, after they move out from under the strip and hot plate. The workers can stand at either or both sides of the table, in order toproperly place the folded hosiery on the belt at one end of the table, and to remove them at the other end thereof. Preferably, the stamped hosiery should remain long enough on the belt to enable the wax impression to cool and harden. Obviously, the decalcomania or transfer unit having the body I can be assembled with the table unit in a manner to permit relatively convenient and easy separation of one unit form the other, for the purpose of making repairs, or for any other desired purpose.
Also with the construction. shown and described, the means for feeding the tape or strip 3, and the means for vertically reciprocating the hot plate 56, are supported entirely at one side of the table unit upon which the belt 5 travels longitudinally. Obviously, the inverted U-shaped casting, shown more clearly in Fig. 4, for supporting the shafts upon which the feed rolls Z'l and 28 are mounted, may be fastened to the under side of the table 2, or it may be supported on the body 5 in any suitable or desired manner. Thus the compact machine unit having the body l is structurally distinct from the table unit, and is set into the side of the latter, in the manner shown, and the continuously rotating shaft 26 of the said machine unit is adapted to be connected to the shaft 33, through the medium of the elements 29 and 3 3, as previously explained, whereby the table unit need support no moving parts except the conveyer belt 5 and the rolls 3 and 4, and possibly the rolls 2'! and 28 as well, although it is obvious that these two feed rolls may easily be a part of the machine unit having the body l upon which all other movable parts are'supported. And, of course, by using the tape or strip 8 transversely of the belt 5, the problem of organizing the two units, and of satisfactorily feeding the strip 8 by means of simple power transmitting connections, is simplified and rendered more satisfactory not only in the manufacture and assembly of a machine of this kind, but also in the commercial use thereof.
