PLATE-IOUNTXNG EQUIPHIENT.

Application filed January 7, 1922. Serial No, 5537546.

To ZZ whom may conce-m lle it known that l? `.aumosti? F. Us' a subject oit the lifting;- oit Sweden, residu St. Paul, in thecounty o'i Ramsey and State ot i "exited new f in common use are. cast iron or wooden bloc rs or lead plates. This equipment is unsatisfactory in that the wood soon becomes distorted by moisture and wear; the cast iron furniture and bases are extremely expensive because each rectangular block must be machined on all sin faces, and the lead turniture and bases soon become worn because of the softness of the material and the frequent cleaning which is necessary. This cleaning gradually removes the surface metal until the plate must be discarded because it is undersize. The metal equipment in common use and especially that made oi lead has the additional fault ci being very heavy so that the speed of the printing presses is greatly reduced, lt is my purpose to obviate these defects and to reduce the amount oi time and labor required in mounting: the equipe ment.

My invention in its preferred embodiment consists of rolled. and cold drawn steel beams or bars oi various widths and uniform standard height (0.759 inch), cut in 'the desired lengths to form bases and furniture of the necessary sizes. In. manufacturing my improved equipment steel bars are irst hot rolled to approximately or slightly over tinished size; are then pickled in a. suitable brine to remove the scalennd the like and are finally cold drawn to the exact nished size,

By this process the equipment is produced at a greatly reduced cost as compared with present equipment and the finished bars more accurate and uniform. Further. the peculiar form and rigidity oi: the bars make them adapted for use as furniture, where the bending force is great, as well as strong enough to wit stand `treat compressing strains as when they are used for a base. lt will be readily understood that by inak- .ing the bars of 1 beam torni in cross section said plates beingindicated .in dottf Fig; 21s a sect1 n taken on the line :2f-2 ci the ,weight rediuedtoa minimum without sacrrcin strength.

1 a( plate being sliownin place on. the base; Fig. shows end views oit three ci the component l beams and Fig. 4- is a detail perspective view of one ot the beams or bars.

Refer-ring; to the drawings, plates 10 and 11 are mounted in the usual chase 12 upon the bases 13., beine' held in place by suitable hooks lll. The chase 12 is filled in byy furniture indicated at 15 and 16.. said furniture being held within the chase 12 usual manner by quoins 17. Ilhe several elements of the bases 13 and furniture 15 and 1G consist of a series of 1 beams or bars 18 of various lengths and widths but oi uniform thickness. The bars 18 are formed with. vertical. webs 18a and horizontal7 'identical 181 and 18c on their upper and lower extremities, respectively. rlhe end surfaces of the flanges 18" and 18 are vertical so that they will bear uniformly one against another when assen bled. As will be readily understood the bars 18 are assembled by placing their flanges 18 on the imposing stone so that the Vflanges 181 present a plain surface upon which the plates are mounted when said bars are used as base. The 'furniture 16 is laidv out in hollow rectangles of the desired size to ll the chase. When laid out as shown in. Fig. 1 with the bars 18 in parallel or vertical relation to each other the quoins 17 hold them 'securely in place, The bases 13, as clearly shown in Figs. 1 and 2, comprise a series of the beams 18 laid in `parallel relation on an imposing; stone or surface 19. p

l prefer to build up the base and turniture from a number of beams, like those illustrated in Fig. 3, viz. of one inch, onehalt inch and one-third inch width so that plates of any desired width in picas may be mounted. rlhe length of the several lv beams differ from each other by multiples of one inch.

Having described my invention what l claim as new and desire to protect by Letters Patent is: l

1. ln plate mounting equipment, al-base comprisine;9 plurality ci bars of uniform height and varying superiieial area adapted to he held 1n parallel relationto each other in a printers forni, each oi said bars being formed with a web and identical flanges projecting at right angles to said web.

rectangular relation tol each other in a printers form, each of said bars being formed With a vertical web and identical ilanges projecting at rightV anglesl to said Web. y

4:. In plate mounting equipment, bases comprising, a plurality of I beams of uniform height and varying flange area adapted to he held in parallel and rectangular relation to each other in a printer-s form.

5. ln plate mounting equipment bases comprising, a plurality of cold drawneteel I beams of uniform height and varying flange area adapted to be held in parallel and rectangular relation to each other in a printers form.

In testimony whereof, I have hereunto signed my name to this specification.
