Y Y Serial No. 850,289.
While-a box involving 'my invention is susceptible 'of general use,.it is of particul lar advantage when used combinationl .with or as -part of a telephone pay station;
' this particular useit is adapted to'inclose `ferent types of boxes employed for ,tele-Aj" lphone pay stations, vone ofthose being cast.
certain ofI thev elements'of suchm'achine.'
.There are generally speaking three' dif- .T-his is the kind of box which is most com-` monlyused. l Itis heavy and cumbersome and can be easily broken to rob the instrument. v
A `boxmadel of'sheet metal is the verybest 'kind in that'it possesses' maximum ystrength with minimum weight. There arev two` types l*of sheet metal boxes now. Iin uselone so costly to'manufacture that its use is. practically prohibitive. 'The other box involves the use of rivets in its make-up, but one of this character has disadvantages owing to the presence of joints into which an implement can vbe readily inserted to pry thebox open.A The rivets are also objectionable in that they afect the resonant connection bef tween the signals and the telephone trans-vv mitter. l
I provide a box possessing the two 1mportant points, namely maximum strength and. extreme lightness, and in addition obviate the necessity of rivets and the necessity of any annealing operations.
In the drawings accompanyingk and forming part of the present specification I have f shown in detail one convenient form of embodiment of the invention, which will beset forth in detail in the following description.A

A telephone'pay station box comprises as a r ule what is known as a lower half as2 and an upper half as 3, (Fig. 16)' and it is one of the primary purposes of the method yto form these halves in a simple, inexpensive and rapid manner from sheet metal.
In Fig. 1 I havel shown a flat blank deas to present a main portion-.5 and a supplemental portion 6 projecting substantially centrallyl in the form of a wing fromthe upper edge of said main portion. In the lower edge of the main portion 5 are cut two approximately rectangular notches 7 and 8 which arepractically centrally intersected by the fold or bend lines 9 and 10 hereinafter referred to, and which notches or slots v7 and 8 as will also hereinafter appear are adapted to -receive filling or corner pieces preferably electrically welded in place, although said filling pieces might be otherwise secured in position. When these filling pieces are secured in position by welding or otherwise, ltheir outer surfaces are practically flush with the outer surface of the upper half or box section 3; as a matter of fact in practice when v-the said upper half is japanned or otherwise treated, the joints .between the filling pieces and the box section cannot be seen. f The-fold lines 9 and 10 are continued across the wing or flap 6. In one ofthe side edges ofthe main portion 5 are formed duplicateI apertures 11 and 12 which in the finished box, are adapted to receive fastenings by which the back (not shown) of said box can be held in place.
Inthe wing or flap 6 is formed an elongatedl slot 13 which receives the usual coin gage as it is known. The sides of the wing first diverge outwardly as at 14 and 15 upon equal angles beyond which said sides are straight and in parallelism as at 16 and 17 Initially by the aid of suitable dies in a'v press of proper kind, the wing or flange 6 is bent on itself along its sides to produce the duplicate ,right angular flangesv18, the folds or bends 'being on ythe lines 9 and 10, said flanges 18 as will be understood, extending inwardly. Subsequent` to this the upper portion of the wing 6 is bent inwardly asat 19 along a line as 20, which lme intersectsthe points where the angular portions 11 and 15 merge respectively in the parallel portions 16 and 17. After the wing is bent on itself on saidline20 to produce theslope 21, said wing as a whole is bent down at right 'angles to and where it joins the main portion 5, this particular operation drawlng the side edges of the flanges 18 into line as illustrated in Fig. 3. Succeeding this action the main portion 5 is bent rearwardly at opposite sides on the lines 9 and 10 to form the sides 22 of the upper half 3, the upper edges of said sides 22 being thus brought into contact or abutment with the straight lower edges of the flanges 18 at which time the sides 22 will be welded or otherwise rigidly united to said flanges 18 along the abutting edges of said parts. While I prefer to electrically 'weld said sides 33 and flanges 18, it is conceivable thattheir union can be secured inother ways. At some stage of the process and preferably while the blank l is flat .the lower notched edge thereof is externally beaded in an outward direction. By the formation of the notches 7 and 8 before the main portion is bent, I find that when the lateral portions of said main portion are folded back to produce the sides 22, there is no tendency to distort or otherwise injure the projecting lower beaded p0rtion of the upper half. In Fig. 4 the upper half is shown i practically completed, the only thing remaining to be done being to insert filling pieces such as the frusto-angular parts 23 in the notches 7 and 8, the filling pieces being shaped .to agree with the notchesand consequently as their designation implies, completely filling the notches and being preferably electrically Welded therein although as will be inferred, they might beheld in place in some other way. In Fig. 5 I have shown the blank 24 on one of these-filling pieces, and this blank by the aid of suitable dies and other instrumentalities will be shaped up to conform in extern l nal appearance to or match the beaded lower part of the upper half 3.
In a telephone pay station the upper half 3 consisting of a front, two sides and a top, contains the chute -and the signal mechanism. The flanges 18 to which I have referred, depend from tlfe topv of the half or section 3. The lower half or section 2 contains the coin-box. -Said lower half comprises a body portion as 25 (Fig. 11) and a front or facing portion as 26. In Figs. 8 and 12 I have shown the blanks from which said body portion 25 and facing portion 26 can be respectively made. The body portion blank denoted in a general way by 27, in Fig. 8, is cut by any suitable dies or otherwise, from sheet metal and as will hereinafter appear the `end portions are bent upward at right angles to the intermediate portion along the lines 28 and 29 from which it will be clear that the main part of the body blank is made up of three approximately equal portions each provided with a projecting wmg 30 all of said wings being alike. -In addition to these wings 30 .the ends of the blank 27 have duplicate mareo?? the outer wings 30. Onthis operation the lines 28 and 29 which results in bringing the weldedv or otherwise united as before deribs 33l can be formed on the upper side of the blank 27, these ribs 33 constituting a guide f or the'money-drawer which I vhave not shown. The abutting ends of the wings 31 and the outer wings 30 can now be electrically welded or otherwise secured together. After this operation the end portions of the blank 2.7 are brought up at right angles to the intermediate portion on the beveled ends of the intermediate wing 30 into abutment against the adjacent beveled ends of the two outside wings 30, and when this is accomplished, said wings can be electrically welded o'r otherwise conveniently united. This makes the body portion 25- of the lower half 2. i y
In Fig. 12 I have shown the blank 34 from which the facing or front-26 of the lower half 2 can be made, said blank 34 like the others being cut by the 'aid-y of suitable dies" or otherwise, from iat sheetstock.- When the blank 34 is stamped out, it has Vpreferably simultaneously cut therein the comparatively-large opening 35-and the smaller opening or slot 36. It 1s through this opening 35 that the coin drawer is inserted, while the openingv or slot 36 is-intended for the passage of coins which maybe returned to a subscriber in case he fails to obtain a conback at some stage in the method, tol conl stitute a partition for separating the slot 36 from the coin-drawer opening 35.y 0n' the.
top wall of said opening 35 is a notched projection or lu 438 which at the same `time that the wing v3 is bent back, can be also bent back, to present a keeper for the bolt of the lock of the moneyedrawer. On the bottom of the blank 34 is a substantially rectangular wing 39 while on the sides are wings 40 and 41, the lower-edges of the wings 41 beingat right angles' to the vertical axis of the blank 34, while the upper edges of said wings 40 and 41 arev along outwardly-diverging angles. Onr the -top ,of the blank 34 is the wing 42, the sides of which-are first straight and in parallelism l and are then along outwardly-converging.
similar angles. The wings 39, 40 and 41 This brings the terminals of the wings 40 and 41 and the upper angular ends of the.-
wings 40 and 41 against the parallel end portions of the steep sloping vpart of lthe wing 42 and` where the several wings arey brought together, they` are' electrically scribed. The upper'portion 43 of thevwing ttl.
blank 34 and all the various operations thus far described in connection with said blank 34 can be accomplished simultaneously to produce the article shown in Fig. 13. After `the step thus described has been performed, the wings 37 and 38 can be b entat right angles and `at the` same time there may be formed around the opening 35. the rabbet 44 as shown in Ifig. 14, to receive the front of the money-drawer. This in fact finishes the face portion 26. The edges of the'wings 39, 40, 4l and 43 can then .be fitted against the front edge ofthe body portion 25 and the two electrically welded 'or' otherwise suitably secured together. To facilitate welding I may if desired upset the metal along the parts which are` to be thus joined, ,the
,upset portions-being preferably coextensive front,vsides and a top, the top having one portion at an inclination and another approximately horizontally disposed, "said top having portions bent downward from the sides thereof and rigidly united with. the up- 4per edges l of the sides .of the box section along straight lines at .substantially right angles. to thelongitudinal axis' of .the box 2. A sheet metal box section having a front, v'sides and a top, the top having oneportion at an inclination and another horizontally disposed, said top also having its sides bent .downward and'welded with the upper edges of the first mentioned sides and the inclined portion being'slotted.
3. Azs'heetf metal box section having a front,sides anda top, said section being beaded at its lower portion and notched in .its lower edge at approximately the junction lof theside's with the front, and filling pieces Welded in the notches and conforming tov the shape of thev beading, said top having its front portion at aninclination and its rear portion approximately'horizontally disposed, the sides of the top being bent downward f and being welded lto the `first men tioned sides, said inclined portion being longitudinally slotted. f
