Claims.

This invention relates to toy locomotives and to the production thereof, and has generally in view to provide for the low production-cost of strong, durable toy locomotive bodies closely 5 simulating large or ordinary commercial locomotives.

According to the present invention, a toy locomotive body is formed from sheet metal blanks, in which connection one of the important objects of the invention is to provide for the forming of a complete locomotive body including boiler, cab, frame, cylinders, boiler head, pilot, etc. from only two blanks which are easy to stamp, to bend or otherwise form to shape and to assemble with each other, whereby the finished locomotive body is, as aforesaid, of low production cost.

More particularly, another important object of the invention is to provide a pair of blanks having a novel assembled relationship such that one serves efiectively to hold a part of the other in its bent or formed condition.

Another object of the invention is to provide for anoverlapping relationship of a pair of the elements of one of the blanks when the latter is bent or formed to shape so that by spot welding or otherwise readily and easily fastening said overlapping elements together allvof the adjacent parts of the blank are held rigidly and securely in their bent or formed condition.

With the foregoing'and various other objects in view, which'will become more fully apparent as the nature of the invention is better understood, the same consists in the novel features'of the blanks, the manner of bending or forming them to shape, the cooperative relationship between the blanks when bent or formed to shape and when assembled with each other, and in the various other featuresof combination, arrangement and mode of forming and assembling the blanks as will be hereinafter more fully described, illustrated in the accompanying drawings, and defined in the appended claims.

In the drawings, wherein like characters of reference denote corresponding parts in the different related views:

Figure 6 is a front View of the formed and 5 assembled blanks.

Figure 7 is a side elevation of a complete toy locomotive produced'in accordance with the invention; and

Figure 8 is across section on the line Fig.3.

'Referring to the drawings in detail, first with particular reference to what will be termed the boiler-cab sheet metal blank illustrated in Fig. I l and designated generally as A, it will be obl5 served that said blank comprises two main body portions designated as lfiand ll, respectively, the former of which is ofsomewhat elongated, generally rectangular shape'and extends from the front or left handend of the blank rearwardly to the dotted line l2, and the latter of which is disposed rearwardly of the portion l0 and extends forwardly to the dotted line I3 paralleling the dotted line I? immediately rearwardlythereof, the rear limit of the portion I! being defined by the front edge of a transverse slot l4.

The side limits of the body portion H] are indicated by the longitudinally extending dotted lines l5, l5, and while these lines'may be parallel to each other, they preferably converge somewhat towardsthe front of the blank as shown. On the other hand, the side limits of the body portion Hare indicated by the longitudinally extending dotted lines IE, it, and While these lines may also be parallel to 'each other, they preferably converge somewhat rearwardly. Moreover, thefront end of the portion l l, defined by the dotted line I3, preferably is of somewhat greater width than the rear of the portion [0, defined by the dotted line I2, so that the relativelynarrow, transversely extending strip ll between the portions I0 and H is of rearwardly flaring form. I

The end portions ill of the slot i4 extend from the side limits of the portion ll of the blank inwardly suitable distances, thence rearwardly as at 59 and again inwardly into meeting relationship in a medial portion 28 which opens through the'rear edge of the blank A, medially thereof, as indicated at 2|. Thus, rearwardly of the body 50 portion ii is formed a pair of

tongues

22, 22 having inwardly directed free end portions disposed rearwardly of the rearmost limit of the body portion l I as defined by the medial portion 20 of the slot 14, and also having outer end pors -s of 10 I tions the

forward parts

23, 23 of which are disposed forwardly of the said rearmost limit of the body portion H.

lhe outer ends of the

tongues

22, 22 define the width of the blank A at the rear thereof, and, as shown, this width is somewhat greater than the width of the rear part of the portion ll of the blank extends a short distance forwardly to

fold lines

2, 24 which extend transversely of the blank and divide the forward parts 23 of the tongues 22 from the rear parts thereof. From the points of junction of the

fold lines

24, 24 with the outer ends of the

tongues

22, 22,

other fold lines

25, 25 extend forwardly, somewhat outwardly of and parallel to the side limits of the portion H as defined by the dotted lines l6, 16, to the front end of the blank A. Thereby, narrow strips 2%, 26 are defined between the fold lines 2% and the side limits of the portions l0 and ii of the blank, the portions of said strips contiguous to the body portion i 0 being of forwardly divergent form as is manifest.

Gutwardly of the

strips

26, 25, between the fold lines 25, 2-5 and the side edges of the blank A are strips 27, 2'! which terminate at their rear ends in alinement with the

fold lines

24, 24 and at their forward ends in outwardly directed

tongues

23, 23, respectively, the forward edges of which are alined with the forward edges of the

strips

25, 25 and are disposed somewhat to the rear of the forward edge of the body portion It! so that the forward part of said body portion constitutes in effect a flange 2e projecting forwardly from the blank A as shown.

Extending forwardly from each tongue 28 is a tongue of a shape to simulate the forward end or head of a locomotive steam chest and cylinder, while extending rearwardly from each tongue 28 is a reversely disposed, substantially duplicate tongue 3| of a shape to simulate the rear end of a locomotive steam chest and cyliner. In addition, each tongue 30 is provided with a forwardly directed tongue 32. I

In forming a toy locomotive body from a stamped or otherwise suitably produced blank of the character illustrated in Fig. l the folding of the blank along the various fold lines does not necessarily follow any prescribed order but, on the contrary, may be considerably varied, and, as a matter of fact, some or all of the folds may be produced simultaneously. In any event, the body portions IE] and H are bent by a pressing operation or otherwise into open-bottom substantially tubular form with the portion II stepped upwardly from the portion l8 as permitted by the strip l'l interposed between said portions, the portion i5 thus being caused to simulate a locomotive boiler and the portion H a locomotive cab.

Due to the forwardly convergent shape of the portion l 5, said portion, when bent into substantially tubular form, is of forwardly tapering shape in accordance with commercial locomotive construction. At the same time, due to the drawingv of the metal in producing the stepped formation H, the sides of the cab simulating portion it become parallel or substantially parallel.

In their bent condition, the bottom edges of the portions i0 and H correspond to the fold lines 55 and i5, and from these fold lines the strips 25 are directed outwardly, therebysimulating the walk boards usually located at the sides of a locomotive boiler and cab. On the other hand, the strips 21 are bent downwardly from the strips 25 along the fold lines 25 and serve to stiffen the fabrication and at the same time to simulate the side portions of a locomotive below the boiler, it being pointed out in this connection that the rear portions of the strips 2? in the present instance are shaped and embossed to simulate the sides of a locomotive fire-box.

Either before or after bending of the blank along the

fold lines

25, 25, the tongues 30, 3| are bent to extend laterally inward from the tongues 28 and the free end portions of said tongues 28 are bent around the bottom curved edges of said tongues 30, 3|, thereby to simulate the steam chests and cylinders of a locomotive.

As the body portions Ill, II of the blank are bent into substantially tubular form the portions 23 of the tongues 22 remain in a common plane and are caused to move inwardly relative to each other to simulate a cab floor. At the same time, the tongues 22 proper, which are bent downwardly along the fold lines 24, are caused to assume an overlapping relationship at their free ends so that they may readily be fastened together as by riveting, spot welding or any other suitable manner to hold the rear portion of the body rigidly in shape. 7 I x Either prior to, during or after the blank A is bent orformed to shape, the same preferably is pressed and pinched at desired points to provide for example, simulations .33, 34 cfsteam andsand domes, respectively, cab window openings 35, air

pumps 36, boiler rivets 31 and, if desired, simulations of any other parts of a commercial locomotive as may be desired. In this connection it will be observed that an opening 38 is-punohed in the body portion H! for the reception of a separate Smokestack simulating element 39 and that tongues 40 are formed to project into said opening 38 for use in fastening the smokestaok simulating element to the body portion in. Also, it will be noted that an opening 4! is punched in the body portion ID to receive the post of a bell simulating element 42, and that the tongues 3! are punched to provide piston rod accommodating openings 43.

Referring now to what will be termed the boiler head-pilot blank illustrated in Fig. 2 of the drawings and designated generally as B, it will be observed that said blank comprises a top portion 44 of substantially circular shape having a marginal flange 45; a medial portion of substantially rectangular shape joined to the top-portion 44 by a neck 41 and having at its upper end laterally extending wings 48; a portion 49 of downwardly and outwardly curved form below the medial portion 46 joined with the latter portion along 'a fold'line 5.0 and flanged at its sides as indicated at 5|, and a pilot or cow catcher sim ulating portion 52fbelow and joined to the portion 49 along a fold line 53. 1 r

The blank B is presse'd orotherwise formed to shape by bendingthe flange 45 ,rearwardly, by bending the neck 4 lreafiv'arclly, by bending the medial portion 46.to extend downwardly from the neck 41, by bending the portion il along the fold line 50 to extend forwardly from the portion 46 by bending downwardly the flanges '51 'fromthe portion 49 to stiffen said portion, by bending the portion 52 downwardly from-the portion 49 along the fold line 53, and by bending the portion 52 along the fold lines 54 thereof into cowcatcher shape as illustratedin Figs. 3 to 6 of the drawings.

Prior to, during or after bending the blank B to shape, the same is orjmay be pressed as desired to provide locomotive front end simulatingfore mations, and after said blank has beenforrned to shape it is assembled with-the formed blank A by engaging the flange '45 overthe front end portion 29 of the boiler simulating body of said blank A. Thereby the front end of theboiler simulating body of the blank A is held in shape by the

portions

44, 45 of the blank B as is manifest. Moreover, in the assembled relationship of the formed blanks A and B, the wings 48 of the blank B fit into and close the open front ends of the spaces below the strips 26 and inwardly of the strips 21 of the blank A, and the medial portion 46 of the blank B overlies the tongues 32 of the blank A so thatby riveting, spot welding or otherwise suitably fastenin said tongues 32 and said medial portion 46 together, the entire frontend of the locomotive body is held rigidly and securely in formed condition.

To provide for equipping the locomotive body with a spring motor, electric motor or other driv- 1 ing means, a transversely extending support 55 is riveted, spot welded or otherwise suitably fastened at a desired point between the sides of the body, and a second support 56 is similarly fastened to one of the strips 26 or 21. Then all that is required to complete the toy is to assemble a wheeled spring or electric motor 5'! with the top body through the instrrunentality of screws or other fasteners 58 engaged with the

supports

55, 56.

Preferably, but not necessarily, diagonal reinforcing ribs 59 are produced between the'portions 56 and 46 of the blank B during forming of said blank. Also, preferably, but not necessarily, wires 6i? are suitably fastened to the body A to I simulate the usual hand rails of commercial locomotives.

As is manifest from the foregoing description considered in connection with the drawings, the stamping of the blanks A and B, the forming of said blanks to shape, and the assembling and fastening together of the formed blanks are rela tively inexpensive, simple matters. Consequently, toy locomotives produced in accordance with the invention are of relatively low production cost. Moreover, due to the cooperative relationship between the sections A and B and to the manner of fastening the rear end of the section A and the sections A and B together, the toy is exceptionally strong and durable.

Reverting to the blank A, it is pointed out that due to the forwardly converging relationship of the fold lines 45, 5", resulting in the formed boiler body being of forwardly tapering form, the front, side portions of the blank are drawn inwardly during bending or forming of the blank to shape. For this reason the fold lines 25, 25 are made forwardly diverging so that when the blank is formed to shape, said

fold lines

25, 25 and the depending strips 2'! have a parallel or substantially parallel relationship. Of course, if the fold lines !5, 15 should be parallel the formed boiler body would be cylindrical, in which event the fold lines 25, 25 would be parallel.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will of course be understood that changes in the form, proportion and minor details of con-' struction may be resorted to, without departing from the spirit of the invention and scope of the appended claims.
