'of applying transfer stamps commonly known as decalcomania stamps to pieces of fabric or such articles as it is desired to mark with said stamps.

While the machine disclosed herein is capable of use for marking a continuous web of fabric, it is also intended to be used I for automatically stamping separate articles,

such as pieces of underclothing, hosiery, neckties or any other articles to which said stamps may be applied. In its general features it comprises transfer mechanism embracing cooperating pressing members, one of which is heated to effect the transfer of the stamps to the fabric and devices for presenting a series of transfer stamps inproper relationship to the articles to be marked and to the transfer mechanism in order to effect the purpose of the machine,

In the drawings I have illustrated a pre ferred form of embodying the principles of this invention. p

sh1p to the series of articles to be stamped, a series of transfer stamps so that when the pressers are actuated the heat of one presser serves to transfer the stam to a predetermined portion of the article presented. To accomplish the proper evolutions there are generally speaking, three sets of-mechanlsm which may be termed respectively the stamp feedmg mechanism, the mechanism for actuating the transfer members and the mechanism or feeding the articles to the transfer mechanism. In the present embodiment of the invention these three sets of mechanism are all actuated and controlled from a single main actuating lever. In practice I employ a power shaft a which by means of gears a, a serves to drive the main actuating shaft a of the machine. On this main actuating shaft is fixed a properly shaped cam a which engages a bowl a carried by the main actuating lever a" from which is derived all the movements of the machine.

I will first describe in detail the mechanism employed for feeding the, garment or other articles in proper relationship to the stamps to be applied and to the transfer mechanism, according to the present embodiment of the invention. This feeding mechanism as shown comprises an endless apron or belt I) passing over rollers ordrums b, 6 arranged at front and rear of the machine. Said rollers may be provided with short spurs or projections b engaging the apron to prevent slipping between the apron and these rollers. The apron derives its movement, which in this case is intermittent, from a train of mechanism which comprises a link 5 pivotally connected with a ratchet lever b which carries a pawl b in position to engage and intermittently actuate a ratchet wheel 72 on the shaft 6 which shaft carries a spur gear I) meshing with a spur gear 6 on the shaft of the feed roll b the link I) being pivotally connected with a lever a. from which it derives its movement. In order to vary the throw of the ratchet a sector-shaped hood or shield I) is adjustably mounted on the shaft 1), the adjustment being made by means of the slotted arm or extension I) and the fastening screw 6, so as to prevent the pawl from engaging the ratchet for as much as the arc of movement of the ratchet as may be desired to give the necessary are of rotation to the shaft 71 It will be understood that when the main lever a descends the ratchet pawl b is retracted and that when the lever a rises the pawl 6 causes a clockwise rotation, (Figs. 1 and 3) of the ratchet and its shaft 6 and consequently a movement of the apron from right to left, the extent of which is dependent upon the arc of rotation imparted to said shaft 6 I will now describe the details of mechw nism for actuating the bed plate in cases where it is desired to have the bed plate move. The bed plate 0 in this case is provided with a yielding cushion a of felt or other yielding material and is supported on vertical slide rods 0 which pass through bearings 0 formed on the sides of the frame of the machine. The reciprocating vertical movement is imparted by means of a link 0 whose upper end is pivotally connected to the main lever a and whose lower end is connected with a lever c which is secured to a rock shaft 0. To the rock shaft 0 is arranged a pair of levers 0 which are pivotally connected to the cooperating levers c, which said levers c are plvotally connected with the bed plate 0. The levers 0 0 form toggle levers the straightening of which by the rotation of the rockshaft 0 serves to lift the bed plate into operative position beneath the belt or apron b, while the flexing of these toggle levers by the reverse movement of the rock shaft 0 serves to drop said bed plate to inoperative position. In order to adjust the traverse of the bed plate so as to accommodate it to articles of different thicknesses the rock shaft 0 has its opposite ends mounted in bearings formed in vertically adjustable slides or brackets a", best shown in Fig. 7 These adjustable slides are of angular shape, the horizontal portion being passed through a slot 0 in the rigid side frame, while the upward ex tension c" of the slide 0 is provided with a slot to receive an adjusting screw 0 by which it is adjustably clamped when set to the desired position. I prefer to provide a special adjusting means for positioning these slides 0 which comprises a rock shaft 0 carrying near its opposite ends lifting cams 0 which lie directly beneath a downward inside extension or'boss 0 formed at the lower inside portion of the slide 0 so that by therocki ng of the shaft 0 both slides 0 are simultaneously raised. and lowered to the proper position, the adjusting shaft 0 being locked when properly set by means of a slotted plate 0 and a binding screw 0. The plate is formed with a handle 0 by which to conveniently rock the shaft 0 When the proper adjustment of the fulcrum slides 0 has been made as just described, the slides are firmly secured in position by means of set screw 0 I will now describe the details of mechanism illustrated by which the upper presser member, which in this case is the heated presser, is actuated. This presser member is shown in the form of a flat plate 03 which may be heated electrically or in any well known, manner, and is supported by a vertical slide rod (2' mounted in upper and lower bearings d carried by a transversely adjustable frame (i (Fig. 2). This frame (Z is made adjustable across the machine by mounting it upon a cross bar d" which passes through a pair of split hubs d which are formed on the frame d'"'. These split hubs are securely clamped upon the cross bar (5 by means of set screws d while the accidental turning or rotation on the bar d is prevented by splining hubs or collars d to the cross bar. As shown in Fig. 3 a lifting collar d is pinned to the slide rod 03, which said collar is provided on its front and rear faces with downward projections or ears (Z which pass between the forks (Z of the forked lifting or actuating lever (PLJ which lever is secured to and actuated by the rock shaft 03. The object of the downwardly projecting ears is to prevent any rotative or torsional movement of the lifting rod 03. The rock shaft (i by which the lifting and dropping of the presser d is controlled, is actuated by means of a lever (Z secured thereon, which said lever a?" is connected by means of the link J with the main lever a", so that when'the lever a descends'the rock shaft 03 rotates clockwise to allow the presser d to descend upon the belt into operative position, while the raising of the lever of causes the presser (Z through'the intermediate mechanism to be lifted away from the feed belt and its cooperating presser member. It will be understood that the shaft d. is mounted in arms or brackets d project-ing horizontally from the fixed uprights (Z of the machine frame. 7 The forked lever al is adjustable longitudinally of the shaft (Z by means of the clamping screw d, which serves to clamp its split hub d securely to the shaft, while permitting its adjustment along said rock shaft to conform to the transverse adjustment of the frame (i I will now describe the mechanism for feeding the tape which carries the transfer stamps. The tape is wound in a coil or roll 6 upon an axis or rod 6 which rests loosely around inclined brackets or arms 6 project ing from the frame of the machine and is kept from moving downward on said brackets by means of the idler roll a which is carried in open bearings formed in said bracket 6 in a position immediately below the tape roll so as to form a peripheral contact and support for said tape roll. The cooperating 12 roll 6 is mounted beneath the roll e in fixed bearings so as to form a support for the roll e As the tape or strip of transfer stamps is fed forward by the feeding means to be described it passes'betweenthe roll a and the presser tape roll e and also between the rolls 0 and e by which it is pinched. The uncoiling of the tape from the roll diminishes the diameter of theroll of tape, but as its supporting rod 6' is free to slide down the inclined bracket 6 the pressure of the tape roll will always rest against the delivery roll 6 by reason of avity. From the lowermost point of the roll e? the tape passes toward the rear of the machine directly above the travel apron b and in the path of the two reciprocating presser members c and d. To the rear of the plane of presser members is mounted a positively driven feed roll a around which the ta )e passes and against which it is pressed y means of the cooperating idler roll 6 whose journal boxes 0 are spring pressed to give the proper pressure or pinch between these two rolls. The feed roll a has on one end of its shaft a pinion e meshing with the intermediate pinion e which is driven b means of the large spur gear a whose shaft is rotatedv at a variable speed by means of the cone 6 and belt 0 and the cooperating cone c in the manner of the usual cone drive. The belt 6 is moved longitudinally of the cone pulleys by means of the shi per til) 6 which is adjustable transversely o the machine by means of the adjusting screw 0 and is held in position by the supporting rod 0 The shaft of upper cone pulley is rotated by means of the ratchet wheel a secured to one end thereof, which ratchet wheel is intermittently driven by means of an oscillating lever- 6 upon which is mounted the pawl e The ratchet arm e is actuated by means of a pivotal link e" having adjustable connectionwith the rocking lever which is secured to the rock shaft a carried by the adjustable frame 03*. The rock shaft 6 is actuated by means of an arm or lever 6 which has a slot (Fig. 6) for receiving a pin e projecting from one side of the forked lever al so that as the forked lever (Z is oscillated by the movement of this rock shaft (Z motion is imparted to the lever e by the slot and pin connection just described to oscillate the short rock shaft e Hence it will be seen that both the tape feeding mechanism and the mechanism by which the upper presser is actuated derive their motion from and are controlled by the link d connected with the main lever a. It Will be understood,however, that while the descendin movement of the lever a, serves to move t e presser (1 into operative position, the pawl lever 6 is being retracted and is not actuating the ratchet which drives the tape feeding rolls; hence the tape is idling while the presser is descending and does not begin to feed until the presscr lifts away from it. A hood 6 similar to the hood 6 may be employed both to regulate the arc of rotation of the ratchet wheel and to,render the pawl inoperative durmg the first part of this forward or feeding movement, so that the presser (Z may be raised entirely clear from contact with the tape before the feeding movement of the tape begins. The tape is fed out of the machine after having left the feed rollers a, e by passing over an.

obliquely arranged guide bar or deflector c and between the draft rollers 0 c the lower end of which is driven by the belt 6" from the pulley 6 carried by the shaft of the drum or roll Z). J

It will be understood that the main lever a is lifted positively by the cam but that the weight of the parts, particularly of the heavy presser (Z is suflicient to cause its descent though the descent may be accelerated by additional weight on the lever a or otherwise. If the operator desires to arrest or prevent the movement of the transfer mechanism, this may be accomplished by swinging a pivoted latch f mounted on the end frame of the machine, into position beneath the outer end of the main lever a. To facilitate this operation from either end of the machine, I provide a rock shaft f extending from the front to the rear of the machine and ,provided at its ends with levers or handles f f The handle f carries a link 7 which engages the latch f so as to control its movement, as best shown in Fig. 2. The adjustable gage 0 consisting of a transverse bar mounted on adjustable supports 0 serves as a guide in properly placing articles to be stamped on the feed apron.
