FRAME STRUCTURE FOR BLUE-PRINTING APPARATUS.

Specification of Letters Patent.

Patented Dec. '7, 1909.

Application filed January 18, 1909. Serial No. 472,846.

T 0 all whom it may concern:

Be it known that I, REIRHOLD HERMAN, a citizen of the United States of America, residing at Grafton, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Frame Structures for Blue-Printing Apparatus, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in blue-printing apparatus, and has particular relation to the frame structure thereof by means of which the various cooperating elements of the apparatus may be fixedly and accurately positioned to provide, vith the supporting frame, a substantially unitary or self-contained apparatus. In apparatus of this type, it he generally been the practice to provide a supporting frame form d of separable members adj ustably connected together, but generally removable for the purpose of providing for shipping, etc. The necessity for the separation of the parts for shipping and other purposes, requires, when the apparatus is to be again assembled, a re-adjustment of the parts to provide accurate movement and etlicient service. As such assemblage of parts requires a high order of mechanical skill it is practically a requirement that the assembling be performed by a mechanic familiar with the apparatus, thus necessitating the supplying of a workman by the manufacturer for this purpose, thereby resulting in increased cost to the purchaser. In addition, the fact that there is a requirement of a great amount of adjustment of parts relative to each other prior to the shipment of the apparatus, and for testing purposes, places in the cost of manufacture the element of time involved in such nicety of adjustments with the result that the cost of the apparatus is increased to a considerable extent. Furthermore, the requirement of a frame capable of being taken apart for shipping purposes, necessitates the use of an excessive number of mechanical elements which, in themselves, owing to the fact that they must be secured to the various frames and attachments on the apparatus, form a weakness in structure physically and the additional fact that liability of misplacement of parts is present. For the purpose of overcoming these objections, I provide a supporting structure which forms a rigid support for all of the elements required in the apparatus, which requires but a minimum amount of adjustment of parts, and this adjustment is made permanently at the manufactory before shipment, the apparatus being assembled and tested prior to leaving the manufacturer and prepared for shipment in the condition. in which it was placed during the testing operation, the consignee receiv ing the apparatus in such condition as to require no action on his part, other than the removal of the crating etc, than to connect the lamp circuit with the source of electricity thereby eliminating all requirement of the attention of a mechanic subsequent to leaving the factory. These results are mainly due to the particular form of the frame employed in the apparatus, and my invention therefore has for its principal object the provision of a supporting frame for blue printing apparatus of a form and construction which will permit of a substantially rigid permanent connection of the operative parts of the apparatus.

A further object is to provide a frame of this character consisting of a minimum number of parts requiring but slight if any adjustment in assembling, which is durable in construction, of low cost of manufacture, and of a character capable of being interchangeable to provide for repairs, or for machines of various sizes.

A further object is to provide a novel support for the frame to prevent lateral swinging and to permit of adjustment for inequalities in the surface on which it is placed.

A further object is to provide a supporting frame for blue-printing apparatus adapted to serve as a support for a printing cylinder held stationary relative to the frame, or for a cylinder which may be rotated on a horizontal axis, or a f 'ame which will permit of a rotation on a vertical axis, to permit access to the various surfaces of the printing cylinder where the apparatus is so positioned as to provide norn'ially-inac cessible surfaces of the cylinder.

A further object of the invention is to provide a supportirig-frame which will permit of the placing of the printing cylinder in position without requiring adjustments of the frame members, or the use of additional temporary bracing means.

To these and other ends, the nature of which will be understood as the invention is hereinafter disclosed, my invention consists in the improved construction and combination of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

lln the accompanying drawings, in which similar reference characters indicate similar parts in each of the viewsl igure 1 is a side elevation of the supporting frame of a blue printing apparatus and showing the printing cylinder in position thereon, said view also showing the lamp carried by the frame. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view taken on line 33 of Fig. 1. Fig. 1 is a sectional view taken through one of the end-rings of the printing frame, and showing its position relative to the printing cylinder. Fig. 5 is a top plan view of the supporting frame at the point of juncture of the vertically extending bars, Fig. 6 is a diagrammatic view of the supporting frame used with a printing frame rotatable on a horizontal axis, and Fig. 7 is a vertical section taken on line 7 7 of Fig. 3.

The main portion of the supportingframe embodied in my invention comprises two bars 10, preferably angular in cross sec tion, said bars being of length sullicient to provide a vertically extending portion of greater length than the length of the print- 111g frame, and a curved portion, designated as 11, the free ends of the curved portions of the frame being brought into opposing contact midway between the planes of the two vertically-extending portions. l v hile the curvature of the bars, is such that, when in position, the ends of the bars are located in the position just described, said bars, as segregated elements, are substantial duplicates of each other, thereby requiring the formation of but a single type of bar for the frame.

To provide the bars against lateral movement when placed in position, 1 provide the lower end of each with laterally-extending feet 12, the ends of which are adjustable, the adjustment being provided by suitable means such as a screw-threaded member having a head threaded into an opening within the foot, the face of the head being adapted to contact with the lioor, this structure being provided to secure a true vertical positioning of the bars where the surface on which the apparatus is supported has inequalities which would prevent a normal positioning of the bars.

The curved ends of tl bars 10, are connected together by means of casting 13, which extends over both of the bar. and is secured thereto. The casting may, if desired, be formed with a bearing extending horizontally and having its axis extending at direct right angles to the plane of the vertical portions of the bars, said bearing being adapted to receive a shaft carrying sheaves for the lan'ip-cables, this construction providing a permanent positioning device for the lamp, and which requires no adjustmentto provide an accurate centering of the lamp over the printing frame and insuring a path of movement of the lamp exactly central of the printing-cylinder, and at the same time securing a proper positioning of the frame of the lamp relative to a normal path of travel of the frame of the lamp in order that the lamp-frame will not provide blind portions at unexpected points within the printing cylinder.

'lihe printing frame, shown in l. and 2, con'iprises the printingv cylinder and the end-rings, the latter being designated at 14:. Said end rings are each preferably angular in cross section and providing portions ex tending in horizontal and verticzl planes in 'ty to the top and, bottom edges of the glass sections of the printing cylinder, said rings being cnshion d relative to said sections by means of strips 15 of suitable material, such as felt, preferably arranged as shown in Fig. 1-.

The printing cylinder is com 'iosed of two semicylindrical sections of a combined circumferential length less than the circumferential length of the completed. cylinder, the side edges of the sections being spaced apart by spacing bars 16, preferably formed of wood, each of said tars having its side edges provided with longitudinally extending recesses 1T, each adapt .d to receive a cushioning means '18, such as felt, the particular arrangement of these parts being indicated in Fig. 3 of the drawings.

The end rings of the printing frame are each provided on diametrically opposite sides with a casting 19 having an angular out vvi'irdly-exteiiding portion 2), adapted to lit within the bars 10, said casting having a normal wieth substantially equal to the width of the vertically-extending portion of the ring 1%, and being elongated to provide a projecting portion 21 extending in the plane of the casting, said projecting portion forming a support for the bar 16, to

)revent' a distortion of the cylinder, said castings being secured to the able bolts and to the spacing bars by suitable screws. The outwardly extending portion 20 is preferably of a length to extend above and below the plane of the edges of the ring 1t. and each casting has its portion 20 pro vided with suitable openings adapted to register with openings within the bars 10 for the reception of suitable bolts when the printing frame is completed.

From the above, it will be seen that the end rings of the printing frame perform a double function, via: to serve as the end rings for the printing cylinder, and at the 19's by suit- Cir same time as supporting members for the l therein by a single bolt; for instance, the bars to prevent spreading movement ring may be moved upwardly from its nor of the bars said rings, with t forming a frame of extreme rig manent in character and substan capable of being moved to disturb tire poaitions in which the parts when the frame is assembled.

The sheaves over which the lamp-cables pass (and which form the positioning means for the lamp axially of the printing-cylinder) are designated as 22; the lamp cables 23, and the lamp 24-.

lVhen the frame is to be used in connection with a printing cylinder having a rotatory movement on a horizontal axis, such as shown in Letters-Patent No. 777,096, heretofore granted to me, but slight 111OCllfiCttions need be made, these consisting in using but one bar 10 of complete length, the other bar extending upwardly from the floor a distance slightly greaterthan required to form the bearing for the trunnion of the printing-frame; forming or securing trunnion-bearings to the bars, and connecting the lower ends-of the bars together by the lower end ring, said ring, however, in this arrangement, not forming a portion of the printing frame, but acting as a connecting member for the frames. The frame is braced by forming the t-runnions and bearings therefor of a type which will prevent their relative axial movement. The remaining portions of the apparatus are the same, the casting 13 and sheaves 22 being provided as in the structure heretofore referred to.

To provide a printing-cylinder capable of being rotated on a vertical axis, to enable the apparatus to be stationed in the corner of a room and be moved to permit access to all portions of the cylinder, it is necessary only to place suitable rollers on the feet 12 and the lower ends of bars 10, thereby permitting the entire apparatus to be moved to provide the result obtained by the use of a cylinder having a rotative movement on a vertical axis.

It will now be understood that with either form of apparatus, the supporting frame is substantially the same, and that such me serves to support all of the mechanisms rcqnired in the apparatus. As heretofore pointed out, the parts which heretofore have required considerable time in adjusting to their proper positions, have predetermined positions in which they are placed in the assembling of the mechanism and which require no adjustment; after the apparatus is assembled at the factory for testing purposes, the adjustments are complete and in proper form to be used by the consignee. After testing, the entire apparatus is crated (with the lamp properly positioned therein and braced and secured) and shipment made. When received by the consignee, it is necessary only to remove the crating, attach the connections for the source of electricity to the proper binding posts and the apparatus is ready for operation without adjustment, unless parts should be broken en route, and this would be generally avoided by the form of crating or boxing, the particular form and arrangement of the fame permitting this to be done.
