SPECIFICATION formingpart of Letters Patent No. 680,687, dated. August 20, 1901. Application filed May 20, 1899. Serial No. 717,538. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT C. BLOOD, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Machines for Printing Stockings and Similar Goods, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

My invention relates to machinery especially adapted and intended for printing on stockings or similar goods, the object of my invention being to provide a machine at the same time simple, eflicient, and reliable for this purpose. The nature of my improvements Will be best understood as described in connection with the drawings,in which they are illustrated, and in which- Figure 1 is a side elevation of my improved machine; Fig. 2, a plan view thereof; Fig. 3, a front view; Fig. 4C, a view of the printinghead, taken as on the sectiondine 44 of Fig. 5. Fig. 5 is an end View of the same printing-head, and Figs. 6 and 7 are elevations of the gear and special devices used for giving intermittent motion to the work carrying platforms.

Aindicates the frame of the machine, upon the sides of which are supported the side pieces of the supplemental frame, (indicated at A,) these side pieces being connected by cross-pieces A A In each of the cross-pieces is formed a longitudinal key-shaped guide and clamping slot, (indicated at a and a b and 1) indicate shafts supported on the main frame and supporting in turn chainwheels B and B, over which run endless chains, as indicated at D, the endless chains supporting and forming part of an endless apron made up of a series of symmetricallydisposed platforms D, having guide-rods, as indicated at cl, against which the goods are placed, as best shown in Fig. 2, so as to bring them in proper registry with the printingheads. On one of the shafts-that indicated at b, as shown is secured a gear-wheel B and also a stop-disk B formed with a series of segmental stop-sections, (indicated at 12 O is a shaft, which, as shown, is the driving-shaft for the machine, having attached to it the fast and loose pulleys O and C 0 indicating the belt, and c a beltshifter.

O is a segmental gear adapted to engage the gear-wheel E the toothed segment being equal to quarter that of the wheel B and the diameters of the gears being such that the shaft 0 will make one complete revolution for each quarter-turn of the shaft 22.

Also secured to the shaft 0 is the segmental disk-stop 0 arranged on the opposite side of the shaft to the segmental gear O and of such form that it will engage with one of the segmental sections in the disk 13 at the instant when the segmental gearB leaves contact with the gear E the engagement being maintained until the segmental gear again engages the gear 13 this device giving a perfect stop-motion and holding the Work-holding platforms in stationary position at all times, except when the intermittent motion is imparted to them by the engagement of the segmental gear with the gear-Wheel B 0 is a bevel gear-wheel secured on the end of the shaft 0 and engaging a bevel-gear E on the bottom of the vertical shaft E, supported in bearings on the frame of the machine. The shaft E has a bevel-gear E at its top which engages a bevel-gear F on the end of a transverse shaft F, supported on the standards A.

G G are brackets, faces G and g of which fit against the cross-bars A and A of the frame and are secured thereto by T-headed bolts-fitting in the clamping-slots a and a as indicated at M M, this mode of attachment permitting the brackets G to be moved across the face of the machine to any desired position. While I have shown two of these brackets, it will be understood that a single one, or more than two, may be employed, if desired. Brackets G are formed with rearwardly-extending forks, as indicated at G said forks being perforated to permit the passage of the shaft F through them, and the brackets are further provided with forwardlyextending arms G G which furnish bearings for the vertically-moving rod actuating the printing-heads, and, as shown, I also se-' cure to faces G G on the brackets G horizontal forwardly-extending guides, as indicated at H H, the arms H being grooved, as indicated at h, to form guideways.

I I indicate levers centrally pivoted to the brackets G, as indicated at I, said levers having cam-rollers, as indicated at I at their rear ends, while their front ends 1 are pivotally connected through a link I with vertically-movable rods 1 moving in bearings in the arms G the lower ends of the rods I being preferably turned down somewhat and provided with a spherical bearing, as indicated at 1 which enters an opening J in the head J. A bar I is secured to the bottom of the rods 1 somewhat above the portions I, said plate being formed with perforations, as indicated at i on opposite sides and serving to secure the rod I to the head J, the upper face of said head being form ed with threaded perforations J 2 J into which scre'w studs J which pass through the holes i in the plate 1 and are secured to the said plate by nuts 9' springs J J being interposed between the plate 1 and the top of the head J, as shown, and an elastic connection being thus formed between the rod 1 and the head J. As shown, the head J is formed with a V-shaped groove in its end face, as indicated at J into which the type-holding form J 4 is slipped, some convenient device, such as a binding-screwy, (see Fig. 4,) holding it in position. Returning now to the top of the machine, F F indicate cam-wheel's, which are secured to one of the arms G of the bracket G and by means of a longitudinal slot, as indicated at f, Fig. 2, keyed to the shaft F, so as to tu rn with it, while free to move longitudinally along it when the brackets G are adjusted.

f (see Fig. 1) indicates the cam-groove in the cam-wheel, and the cam-roller I on the lever I is engaged in this groove.

For the purpose of inking the type in the head or heads J, I provide an ink-holding box K, on the sides of which are formed projecting lugs which run into the slots h of the guide-arm's H.

K is an inking-roller supported in the box K.

A is a connecting-rod secured to one end of the bell-crank lever K K, which is pivoted at K and has at the end of its arms K a cam-roller 70, working in the cam-groove on the face of the cam-wheel F, as shown in the same cam-groove f which ac'tuates the lever I.

In the operation of the machine the operative places the stockings on the platforms D, as best indicated in Fig. 2. The endless belt or apron of platforms is then intermittently fed forward by the action of the driving-gear described, bringing each platform in ing is effected, of a frame-standard turn toa position of rest beneath the printing-head, and while it is held there the action of the cam-wheel F acting through the mechanism described, forces down the printing-head until the desired impression is made on the stocking. The head then rises, and while it is in its upper position and while the platforms are making another intermittent movement forward the action of the camwheel F forces the inking box and roller forward under the printing-head, so as to impart a fresh layer of ink to the type, the reciprocating movement of the inking box bringing it back to the position shown in Fig. 1 before the printing-head again descends to print the stocking held on the next successive platform.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for printing on stockings and similar goods the combination of endless feed-chains carrying a series of fiat platforms, means for feeding the chains and platforms forward with an intermittent movement whereby each platform is brought in succes sion beneath the printing-head, means for locking the chains and platform in position during the intervals of their movements, gages on each platform to regulate the position of the work thereon,- a reciprocating printing-head arranged to operate on the work when on a platform beneath it and means for operating the printing-head dur ing the dwell in the movement of the workholding platforms.

2. In a machine for printing on stockings and similar articles, the combination with shafts as b and b, feed-wheels, as B and B, mounted thereon and endless feed-chains carrying a series of platforms supported on said wheels, of a gear-wheel as B and a stop-disk as B secured on one of the shafts, said disk having a series of segmental facets, as b b &c., a driving-shaft O, a segmental gearwheel C secured thereto and adapted to intermittently engage and operate gearB a stop disk 0 also secured to shaft 0 and adapted to engage and interlock with the facets of the stop-disk 13 at and during the time the gear 0 is disengaged from gear 13, a reciprocating printing-head, as J, and means operated by the driving-shaft for operating said printing-head during the dwell in the movement of the platforms.

3. In a machine for printing on stockings and similar articles, the combination with a series of platforms adapted to support the articles to be printed and means for intermittently moving said platforms to bring them in turn to the position where the print- G extending above the level of the platforms, a longitudinally-movable rod, as 1 supported on the standard G, a printing-head J supported on rod 1 means for reciprocating the rod and printing-head is in its uppermost position and head to print the goods and to elevate the for the purpose of inking the type in said head after printing, a horizontal guide H sehead.
