METHOD'OF MAKING REENFORCING UNIONS Filed Jan. 2, 1930 was Patented Jan. 26, 1932 cri es-Tues PATENT OFFICE ROBERT M. cIIEsnEIr, or WARREN, OHIO, nssrenon, :BY MESNE ASSIGNMENTS, r UNITED STATES GYPSUM COMPANY, or CHICAGO, ILLINOIS, A conronarron or ILLInoIs construction boards and, more-especially, the
type of unionshown in my co-pending application, Serial No. 360,731, filed May 6,
' By the use of my invention, I am enabled to make such a union with relatively narrow upperflanges or legs andalso provide said flanges with'the plaster-retaining loops in the process of manufacture.
By the use of my invention, a union of the type shown can be economically manufactured out of sheet metal. 7
Other features and advantagesof my invention will appear more clearly as I proceed with my specification.
In that form ofapparatus shown in the accompanying drawings for carrying out my. invention Figure 1 is. a view in front elevation showing the first step in the process of manufacture;Fig. 2 is a similar view showing the second step; and, likewise, Figs. 3, a, 5, 6 and 7 are similar views showing, respectively, the succeeding stepsin sequence; Fig. 8 is a view in side elevation of the apparatus shown in Fig. 5 or 6, and Fig. 9 is a view in perspec tive of the completed union, showing the same in use.
. It will aid in the understanding of my I invention if I first describe the completed union; type. shown 111 my As stated above',this union is of the co-pending application, Serial no. 360,731, filed May 6, 1929. The completed union is shown in Figs. 7 and 9. It will beseen that itisin; the shape of a channeled section, somewhat like the letter I, and comprises abase 1, web sections 2, 2, andflanges or legs 3, 3.
The base 1 is formed with'flangeshaving a double wall giving it greaterstrength and to furnisha rigid'support for the remaining parts of the union. The web sections 2 are formed a short distance apart so as to leave therebetween a groove 4. The channels lying back to back between the base 1 and the flanges or legs 3 are adapted to embrace the edges of wall boards or construction boards.
A, A, as shown in Fig. 9.
METHOD OF MAKIN G REENFORCING UNIONS The union shown in my co-pending application, above referred to, has the flanges or legs 3 considerably wider than the base 1. The union shown in this application also has the flanges or legs 3 wider than the base 1 but only a very little wider. That is, the flanges or legs 3 of the union here shown are considerably narrower than those shown in my co pending application, but still preferably slightly wider than the base 1. The flanges 3 are provided with projections in the form of outwardly projecting loops 5 which are formed by slitting the flanges and extruding the slitted bands. The loops 5 serve to retain plaster which may be placed over the joint and, also, serve as grounds to insure the placing of plaster of sufficient thickness over the joints. These loops may be formed in any desirable shape and number.
One of the particular features of my invention is the designing of a process permitting the manufacture of a union with relatively narrow flanges or legs 3 in which the loops 5 lie above the base part 1. It will be seen that in such a union, the loops 5 cannot be easily formed after the union is completed, since the projecting flanges of the base 1 will prevent making such loops with rotary cutters. In the practice of my invention, however, I form such loops before u the legs or flanges 3 are bent into horizontal position. These loops are cut and formed into the union when the flanges are in the position shown in Figs. 5 and 6, and it will be seen that when in this position, rotary cutters may be employed, as will be described more in detail hereinafter.
In assembling a wall or composition board, the edges of two adjacent boards A are placed within the channels formed between the base 1 and flanges 3, as shown in Fig. 9. The union may be secured to a frame or stud 6 by driving a nail 7 into the center groove l and through the base 1, as shown in Fig. 9.
I shall now describe more in detail the process of forming the union.
The first step is illustrated in Fig. 1, in which the strip of sheet metal, indicated, in general, by 7, is passed between the two rolls 8 and 9. These rolls, as shown, are formed I to bend the marginal edges of the strip of the bend ll eventually forms the legs or flanges 3, 3. In the second step shown in Fig. 2, the portionsbetween the bends 10 and 11 are bent upwardly at right angles to the base 1. In the step shown inFig. 3, the
in the step shown in Fig, 4, the portions between the bends 12'and 10 are bent downwardly flat against the lower part of thebase to completethe base portion 1. a
The particular feature. of my improved process lies inthe fifth, sixth and seventh steps, illustratedrespectively in Figs. 5, 6 and 7. It willbe seen that after the fourth step, illustrated-in Fig. 4, the union will-be in the form shown in Figs. 5 and 6. It is to be particularly noted that the legs. 3v have been formed but the same are not yet bent downparallel with the base-1. In the fifth and sixth steps, the loops 5 are formed in the flanges 3. Since the flanges 3 are not yet bent down parallel with the base 1 but lie in obtuse angular relation thereto and with each other, the loops 5 can be formed in. said flanges with rotary cutters. Such rotary cutters, for eXample,may-in.clude a. pair of rolls 13 and14 as'shown in Fig. 8, the former being provided with a peripheral groove 13- andthe; latter, with rounded projecting cutters 14 Each flange 8- ispassed between a pair of these rollers, as shown in Figs. 5 and '6, and the cutters 14 cut parallel slits in the flanges E-and eX-trude or stretch out the sl'i'tt'ed band to form the plaster-retaining loop- 5. If the flanges 3 were parallel with the basel, the rotary cutters 1 3 and 1 1. could not be used without making said flanges wide enough sothat-the base 1 would not interfere with the cutters. By cutting these loops when the flanges dam in the angular positionshown, the rotary cutters may be used, even though such flangesl'are narrow, as shown. 1 v j 7 After .the loops 5 have been formed, the flanges 3 are bent down intoparallel relationwith respect tothe base 1 by means. of the roller. 15-, shown. in Fig. 7. This roller is provided with? flanges 15 engaging the extreme edges of the flanges 3. It isalso pro:- vided with a deepcentrally arranged flange l5 adapted to enter the groove 40f the union. The recesses 15 accommodate the loops 5. Numeral 16 indicates alower supsides of the union.
