MACHINE FOR PRINTING GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 491,025, dated January 31, 1893.

Application filed May 23, 1891. Serial No. 393,865. (No model.) I

To all whom it may concern:

Be it known that I, CHRISTIAN Z. F. Ror'r, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in Ma chines for Printing on Glassware; and I do hereby declare the following to bea full, clear, and exact description thereof.

My invention relates to apparatus for decorating lamp chimneys and like articlesof glass-ware, its object being to provide a form of apparatus by which designs or ornamentations may be imparted to the surface of such articles of glass-ware in rapid succession, to be subsequently baked into the glass to retain indelibly the design imparted thereto.

To these ends myinvention comprises, generally stated, a traveling carriage having a type carrier secured thereto, type so mounted in the type carrier as to lay with an even horizontal surface for inking, and conform to the bulbous, or other shaped body of the chimney or other article during printing, and mechanism for rotating the chimney at such speed that its surface will move with the type block, so that the design may be printedaround the cylindrical body.

My invention further comprises certain improvements in the arrangement and construction of the several parts embodied in the operation of such a form of apparatus as above generally stated, all of which will be more fully hereinafter set forth and claimed.

To enable others skilledinthe art to make and use my invention, I will describe the same more fully, referring to the accompanying drawings, in which Figure 1 is a plan View of the apparatus; Fig. 2a side view; Fig. 3 is aplan view showing the carriage advanced to its extreme forward position and about toretreat; Fig. 4 is an enlarged side view partly broken away, with the carriage in its advanced position; Fig. 5 isacross-section on line (5 ,5); Fig. 1; Fig. 6 is across-section line (66) Fig. 1, showing the chimney in full lines during the printing operation; Fig. 7 is an enlarged view of device: for conforming the type blocks to shape .of; chimney; Fig. 8 is a face view showing the.

chimney holders removed; Fig. 9 represents opposite side to that shown in Fig.4; Fig. ll

is an enlarged longitudinal section of the longitudinal beams forming the frame and showing the beveled edges of the guide-bars by which the type blocks are canted; Fig. 12 is an enlarged top view, partly broken away, of the frame and the type carrier. Fig. 13 is an enlarged plan view of the forward end of my improved printing machine after the typecarrier has advanced to the front end of the frame and is about to recede;Fig. 14 is across section on the line 14-14, Fig. 13, looking in the direction of the arrow; Fig. 15 is a cross section on the line 151'5, Fig. 13, showing the manner in which the type blocks arejournaled in the type-carrier at the forward end thereof; Fig. 16 is an enlarged View of the sprocket wheel and chain in cross section, together with the crank arm for reversing the direction of the movement of the carriage.

Like letters indicate like parts.

The frame which supports the apparatus consists of the standards A, the longitudinal beams A and the cross-beamsA The sliding carriage a-travels to and fro in the guideways a formed in the longitudinal beams A, and to provide for this advancement and withdrawal of said carriage a in its guides, a crank arm b is journaled at oneend on the bearing b secured to the carriage, the other end of said crank arm being secured to the driving chain c by bolts or other suitable fastening devices. The driving chain c engages with the sprocket wheels 0 0 which are on the same horizontal plane as the bearing 1), the front wheel 0 being secured to the journald at the forward end of the frame, and the rear sprocket wheel 0 secured to the power shaft 01'. By such a construction the carriage is drawn forward by the chain and when the crank arm 19 reaches the sprocket wheel 0 or c it swings on its bearing passing around the wheel, and passing above or below the wheel, and then draws the carriage in the op- .posite direction, the table remaining stationary at one or the other end of its stroke, when wheel.

Mounted on the carriage a and adapted to travel back and forth therewith is the typecarrier e. The type-carrier e is constructed in accordance with the design or ornamentation it carries, and the size and shape of the article upon which it operates to produce the design. In the drawings, 1 have illustrated a type-carrier carrying a design for the ornamentation of lamp chimneys or such like bulbous bodies, the design itself consisting of three bands encircling the chimney, as shown in Fig. 9. The type-carrier e is composed of the side bars e and the end bars 6 It is obvious that to impart the design to the bulbous or convex portion of the lamp chimney, the types embodying the design must conform with the contour of that portion of the chimney to be ornamented. If, however, the type blocks be permanently secured within the type-carrier with their faces in conformity with the surface of the chimney to be ornamented, it will be a matter of much inconvenience to apply the substance to the type blocks which imparts the design to the glass. To provide for this inconvenience, the type blocks are so adjusted within the type carrier that when in position for applying the substance to them to impart the design, the faces of said typeblocks present an even face, but when brought into contact with the chimney they are made to conform thereto in the manner hereinafter set forth.

For this purpose the outer type-blocks f are provided with journals f at the ends thereof bearing in the bearings f in the end bars e of the type-carrier. At the forward ends of the type-blocks fare the pins 9 held normally horizontal by the spring arms 9, said spring arms 9' being attached to the bearings f of the type-carrier e, but when the pins 9 en- .gage with certain guide bars upon the advance of the type-carrier e, as will more fully appear, said pins are raised which act to cant the type-blocks and bring them into conformity with the chimney. Beneath the type blocks f as well as the central type block h are the springs f which act to cushion said type blocks f and h during the printing operation. The central type block it remains stationary, being perman ently secured at both ends to the cross-bars e Just in advance of the type-carrier e and slightly to one side thereof is the rack i, said rack being adapted to slide to and fro in the guides z" formed in the frame of the apparatus. A cord or chain j is secured to the rear end of the rack 73 as at 2' and passes thence over the pulley j secured to the stud 3' of the frame. A weight k is attached to the end of the cord or chain j.

To provide for the advancement of the rack t' in its guides 2", a rodlis carried by the rod in the manner hereinafter described). A cord or chain Z is secured to the rear end of the rodZ to the lug Z and passes forward over the pulley l secured to a depending bracket on the traveling carriage. A weight Z is attached to the end of the cord or chain Z and as will more fully appear in the operation of the apparatus, the weight Z must be heavier than the weight is attached to the cord j.

The racki engages with the pinion m secured to the shaft m mounted in hearings in the arms m said arms being connected by the cross arms m This chimney supporting frame formed by the arms m and cross-arms m is hinged at m to uprights m on the main frame A. This construction permits of the swinging of the supporting frame toward the front end of the machine. The height of this supporting frame may be adjusted by means of the depending lugs m m on the rear cross-arm m The lugs m m are adapted to be moved along the said cross-arm and the lugm is longer than the lugm In traveling along the cross-arm m the lugs m m come in contact with the inclined top of the rib m whereby as said lugs travel up said inclined rib m the supporting frame is raised to correspond to the size of the chimney to be printed on. Secured tothe inner end of the shaft 1% is the bracket 07. which supports the base of the chimney, said bracket n having the curved arms 11' pivoted thereto adapted to embrace the base of the chimney and hold it firmlyin its grasp, and for this purpose the spring n is interposed between the lower ends of said arms at to throw said arms normally around the base of the chimney. To allow for the opening of said arms to remove a chimneyor insert one therein, pins 02 engage with slots n on'said arm's n, the pins a being secured to the bracket n and traveling in the said slots 02, upon the opening of the arms it. On the shaft m is another pinion 0 which -meshes with a pinion 0' on the shaft 19, said shaft extending over the frame of the apparatus to the opposite side and supported in suitable bearings. On the inner end of the shaft p is the pinion p which meshes with the gear wheel q secured to the journal q. A bracket g similar to the bracket 12 on the opposite side is secured to the inner end of the journal q, and said bracket is likewise furnished with curved arms 'r'adapted to embrace the neck of the chimney, after the manner of the curved arms n, being provided with the spring 4" and the slots or engaging with the pins r on the bracket (1 The bracket g is further provided with a head piece 8 to prevent any longitudinal movement on the part of the chimney when held by the arms of the brackets. This head piece 8 is secured at its ends to the pins 8' on the bracket g the coiled springss being interposed between said head piece and the bracket to force said head piece normally into contact with the head or top of the chimney, to aid in the support of said chimney. If de-" ICC Y type carrier 6.

sired thehead piece 8 canbe used in the base holder at as illustrated in Fig. 8.

As hereinbefore set forth the type blocks f are so adjusted within the type carrier as to be capable of being canted in their bearings f in order to bring the face of said type blocks into conformity with the bulbous surface to be decorated. To. provide for this canting of thetype-blocks f guide bars 25 are secured to the top of the frame beginning at points just to the rear of the chimney supports. The guide bars t have suiiicientfspace between them toallow for the passageof the- The rear ends of said guide bars 25 are provided with the inclined faces t while the inner edges of said bars are beveled as at 25 so that on the entrance of the typecarrier e within the said guide bars, the pins 9 of the type blocks f will travel up the inclined faces 25 to gradually cant the said type blocks, and then along the beveled edges t thus cantingsaid type blocks as long as the pins 9 travel along the beveled edges 1?. I

A bar or rod u is secured to the frame below the rack i, said rod having the stops or lugs 11. thereon with which the ends of the rack come in contact, when it moves back and,

forth thereby regulating the distance said. rack is to travel in its guides.

In the operation of myimproved apparatus the several parts are first brought to their respective positions with relation to each other,

as shown in Fig. 1. The substance which imparts the ornamentation to the chimney is applied by a suitable roller to the faces of the type-blocks f andh and a chimneyis inserted in the brackets 71. and V g the base of said chimney embraced by the arms n' and, the neck thereof by the arms 0". Power is then exerted to drive the shaft cl, and through it the driving chain 0. Since the driving chain c is connected to the carriage a by the crank incident with the advance of the carriage, a

and the type-carrier e, the rod Z has also been advancing, and just as the type-blocks are about to pass under the chimney with their faces in contact and conforming therewith, the end of the rod Z collides with therear end of the rack t. Upon the further advance of the carriage a the type-carrierewith its typeblocks f and h in contact with the chimney passes under said chimney, while at the same time the chimney is rotated in its brackets. For as the rod Z advances the rack 21 the pinion 'm rotates the shaftm' and the brackets n holding the base of the chimney,while through positions.

the pinions 0 o'the shaft 10 and pinion p and gear wheel q, a likerotary movement is impartedv to the bracket qdsupporting the neck of the chimney. This simultaneous movement of the type-carrier e, with its type-blocks in contact with the chimney, and the rotation of the chimney, will obviously produce the effect shown in Fig. 9, adesign consisting of three clearly defined bands completely encircling the chimney. The rack t' is made of a length sufficient to impart through the mechanism described one complete revolution to the brackets 42 andfwhich, supportthe chimney. When the type-carrier c has passed beyond the chimney havingimparted the design to its entire circumference, as shown in Fig. 1, the rack 1' has reachedits extreme forward movement and abuts against the forward stop'u'i' on the I'Od/tQ WhilG the weight k which has beengradually elevated by the advanceof the rack t assumes the position shownin- Fig. 4? The carriage a continues to advance a short distance after the stoppage ofthe rack '5 to permitof time to withdraw the chimney before the carriage begins its retreat. It is evident that with the rod Z in contact with the end of the rack 75, the said rod cannot accompany thecar-riagein this further movement. The .weight Z? acts to hold the lug Z on the rod Z in. contact with the adjacent end of the sleeve Z, and said weight Z being heavier than the weightk, the. result is that as the rodZadvancesand meets the rack i saidrod drives forward the rack iand raises the Weight 7a. 7 When the rackvl has reached the extreme limit a of its forward movement, the rod Z is also brought to a standstill, but as the carriage still advances a short distance the sleeve Z willconsequently travel along the rod Z for a short distance, the cord Z sec'u red to said rod passing up over the pulley Z moving with the carriage, thus elevating slightly the weight Z At this stage of the operation the crank arm b passes over the front sprocket wheel 0 when that portion of thedriving chain to which it is secured and which hitherto has been advancing, returns to the rear of the apparatus. Since said crank arm I) is also secured to the carriage a the said carriage together with the type-carrier e and rod Z return to resume their original Upon the first backward movement of the carriage ct the weight Z will be lowered and. the arm Z resumeits former position with respect to thesleeve Z. After this sprocket wheel c' and again carried forward the carriage a, when, a chimney having been inserted in the brackets, the operation just described is repeated with the same result.

Any suitable substance may be employed for printing on the chimneys, either an ink or paste'containing the vitrifiable color, so that the same is applied directly to the chimney, a sticky substance over which the powdered color or etching substance may be dusted, or an etching substance in paste form. Such printing substances may either be applied by means of inking rollers mounted on the machine and inked in the ordinary way, or by means of a hand-inking wheel, the latter being preferable where the sticky substance is applied to the chimney, as one application thereof will be sufficient for inking several chimneys, and the operator can easily attend to the inking.
