To all whom it may concern:

e it .knownthat I, ALBERT LESLIE LAM- BERT, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain' new and useful Improvements in Grab-Handles for Car-Seats, of which the following is a specification.

My invention relates to a pressed metal grab-handle adapted tobe secured to a corner of the back of arailway car-seat. Grabhandles have previously been made of cast metal of either ir0n,-steel or brass. Myimproved construction comprises a section of tubing which is notched'at' the ends of'the curved handlepo'rtion, the end portions eX- tending beyond the notches having the walls of the tube pressed together to form arched portions of double thickness adapted to lie against and be secured to the" end and top A cross-member is provided whichis pressed with a die to an arched section with closed ends, the end portions of this cross-member beingformed upwardly. with its ends abutting'the main member at the junctions-of the end portionsand the tubular central or handle portion. The two his position and then ground down, the end portions of the crossmember joining the ends of the central portion of the main member toforma smooth curve. Projecting lugs arealso'preferably made of formed metal and welded to the cross-member, so as to extend into the edge of the seat-back at locate the handle. it

The pressed metal handle as thusformed is much lighter than the cast metal handles as previously made, and further is considerably cheaper in manufacturethan the cast 1 metal handles. A further considerable advantage consists in the fact that a steel handle will take white enamel, particularly porcelain enamel very well, which is not the case with a malleable iron handle. Gray iron will take a white enamel, but must be large and bulky in order to get sufficient strength. Accordingly, my improved design affords a light, cheap and efficient construction which will take a desired finish, which is impossible with other handles which may be considered practicable.

In order that my invention may be more clearly understood, attention is hereby dielevation of This cross-member is positioned.

the corner to properly drawings formand illustrating invention. In Figurel represents a side eleimproved grab-handle applied back, Fig. 2 is an enlarged side the handle before welding the parts together, Fig. 3 is a similar view, showing the parts separated, and Figs. 4 and 5 are enlarged sections taken, respectively, on lines 4 4 and 5-5 of Fig. 2.

eferring to the drawings, the main piece '1 of the handle is made of a section of tubing, preferably of steel, which is notched, as indicated at 2, 2, and bent to the desired curvature. The

end portions

3, 3 extending from the

notches

2, 2 to the ends of the piece are straight and are given the conformation required to enable the same to lie against the end and top edges 4 and 5 of the seat-back 6. This is preferably accomplished by pressing the inner surface of the tubing against the outer portion of the tubing, so as to give the end portions of the piece an arched inwardly curved cross-sew tion of double thickness, asindicated in Fig. 4. This, or" course, insuresrigidity in the portions of the handle which are to lie against and be secured to the seat-back.

Suitable openings

7, 7 are formed through the end portions 3, through which screws 8 may be passed to secure the handle to the back 6. 1

The tubular central portion of member 1, indicated at 9, is preferably flattened somewhat in cross-section, so that itssection is approximately oval. The extreme ends of the central portion, however, are not flattened, so that inwardlyflaring end portions 10 are formed.

he cross-member 11 is also preferably made of steel and pressed in a die to the desired shape, this member being somewhat arched downwardly in cross-section. At its ends, the cross-member is pressed upwardly to form raised top portions 12 and closed end portions 13,

The lugs 14, which are adapted to be inserted in openings of the corner portion of the seat-back, are preferably pressed from sheet-metal and welded to the cross member 11, as shown. These lugs are preferably pressed into the form of cups, as shown in Fig. 5, with flanges 15 which are welded to the cross-member l1.

rected to the accompanying 111g part of this application certain embodiments of my the drawings vation of my to a car-seat The cross-member is positioned across the central tubular portion of the main member with its closed end portions 13 resting in contact with the end portions 3 adj acentrto the notches 2. When so positioned, the raised end surfaces 12 of the cross-member lie in contact with the lower edges of the flared ends 10 of the tubular portion 9. The members are now welded together in this position, after which the welded joint is ground down, so that the outer surfaces of the handle member and the cross-member join together smoothly and continuously, the end portions of the cross-member, and the flared ends 10 .of the handle portion 9 joining to form a smooth curve, as indicated at 16, in Fig. 1. The completed handle may be mounted as indicated in Fig. 1.

\Vhat I claim is 1. A grab-handle of pressed metal comprising a curved member having a tubular central portion and end portions of inwardly arched cross-section, and a cross-member of downwardly arched cross-section with closed ends, welded at its ends to said curved member adjacent the ends of said tubular central portion, the end portions of said cross-member being formed upwardly to join the ends of said tubular portion, substantially as set forth.

2. A grab-handle of pressed metal comprising a curved member formed of tubing, having a tubular central portion and end portions of double thickness, the inner side of the tubing being pressed against the outer side, and a cross-member of downwardly arched cross-section with closed ends, welded at its ends to said curved member adjacent the ends of said central portion, the ends of said central portion and the end portions of said cross member being so formed as to join together, at their inner surfaces, with a smooth curve, substantially as set forth.

3. A grab-handle of pressed metal com prising a curved member having a tubular central portion and straight end portions adapted to be secured to an end and top edge of a seat-back, and a cross-member se- Oopiea of this patent may be obtained for ortions will be Welded to,

cured at its ends to said curved member adjacent the ends of saidcentral portion, said cross-member having end surfaces contacting and secured to said straight end portions, said tubular central portion of the curved member having flared ends, and said cross-member having curved surfaces adjacent its ends which join said flared ends, when said cross-member is secured in position, with a smooth curve, substantially as set forth. a

4. The process of forminga grab-handle for car-seatbacks, comprising, notching a length of metal tubing at a pair of intermediate points, bending the portion between the notches to a desired curvature, pressing down the end portions beyond the notches to form sections adapted to lie against edges of the back, and securing a cross-member across the curved member so that its end portions will lie adjacent to and be continuous with the ends of said tubular curved portion of said curved member, substantially as set forth. 7

5. The process of forming agrab-handle for car-seat backs, comprising, notching a length of metal tubing at a pair of intermediate points, bending the portion between the notches to a the end portions beyond the notches to form sections adapted back, pressing a cross-member of sheet-metal with channel section, pressed-up end portions and, closed end surfaces, and welding the cross member across the curved member,

so that its .end surfaces will be welded to pressed-up end said end portions and its and contlnuous to lie against edges of the desired curvature, forming with, the ends of the tubular curved portion of the curved member,

forth.
