SEWING-MACHINE TABLE.

Specification of Letters Patent. Application filed July 27,1906- flerial No. 328.063.

rammed Feb. 26, 1907.

. My invention relates to-the construction of tables for manufacturing purposes, and more articularlv work-tables for sewing-machines or use in factories; and my invention is to construct such a table so adaptable various sty es or arrangements of table-tops and so that the supports'may be convenientl shipped without packing and yet without anger of breakage.

' drawings, Fi re 1 .In the accompanying is an end elevatlon of a single table. ig. 2 .is a similar view of a double table. Fig 3 is a section on the line 3 3, Fig. 2. Fig. 4 1s an end view of a modified form of double table; and Fig. 5 is a erspective view of the same,

i the bolts and nuts being omitted for the sake of simplicity.

The table legs or frames of sewing-machine or other work-tables for factory use allow of little have usually been made of cast-iron, and these have to'be carefully acked for transportation to prevent brea age. They also or no variation in the positions of the bearings for the counter-shaft. I build my supportingeframes of rolled or otherwise wroug t flanged bars, principally channelbars, of iron or steel, so that they need little or no packing for transportation and they rious types or styles of tables.

allow a wide range of location and adjustment for the shaft-bearings, and similar parts may be made up to constitute frames for va- In each case each supporting-frame is made u of two uprights A, a top cross-piece B,( or B and a lower cross-piece B. Each of these up rights and cross-pieces is composed of two channel-bars or angle-bars, as a a or b 6, arranged back to back and riveted or bolted together, but with a space between the two channel-bars. I prefer to use channel-bars for-the uprights and lower cross-piece and angle-irons for the upper cross-piece. The cross-piece B is united to the uprights by the main object of with a slotted web e corner-webs 7 7 which may be riveted to the crossiece and may be secured to the uprights y bolts and nuts 8, a series of o enings (holes or slots) being formed in t e uprights to enable the cross-piece to be secured at an .desired height. In the difierent views 0 the drawings I have shown this lower cross-piece as,secured at three different heights. The upper crosspiece will vary somewhat in size and shape with the varying style of table-top used. Thus in Fig. 1 I have shown a single table with a fiat top H, and the cross-piece is a short straight iece B, composed of two angle-irons, whic may be riveted together and to intermediate corner-w ebs 9, by which the top may be bolted to the uprights by bolts and nuts 10.

In the case of the double table shown in Fig. 2 the upper cross-piece B is longer and extends conslderably beyond the uprights, to which it is united by double corner-webs 11. In the case of the double table with intermediate trough T the angle-irons of which the upper cross-piece B is composed are bent to accommodate the trough, as shown in Figs. 4 and 5. In addition to thedouble cornerwebs 12 there may be inserted stren theningwebs 13 at the angles of the .troug Fig. 4. In each of these constructions it will be preferable to provide slots in the webs 9, 1 1, and

12 for the passage of the securing-bolts, as

indicated by dotted lines in Fig. 4, to give a suitable range of adjustment as well as convenience in assembling. In the case of the sin 16 sewing-machine table, Fig. 1, Iv hinge to Elie back at a: a delivery-apron D, and to the apron Ipivot one or more braces d, with holes or-slots to receive securing-bolts 14, passing throu h holes in the rear uprights, and so to hold 51c apron at any suitable adjusted anle convenient for the delivery cm the sewing-machines.

One of the principal advantages of my improved construction of table-frame is that it adapts itself to varying positions of the counter shaft, and in connection with the frame I have adopted a special form of hanger for the bearing of the shaft-that is to say, I provide the hanger E (E) of whatever form which may be inserted at any suitable point between the channel-irons of either the cross-beam B or of the goods III l I 5 pairs of flanged bars with c the upright, as shown in Fig l and there seback to back but spaced with hangers for cured by bolts. 15. passing through slots in shaft-bearings having webs adapted to be sethe beam or upright and held by suitable cured between adjacent bars.
