Application filed July 11. 1907. Serial In. 383,2!6-
forming sheet metal rece tacles, and has for:
its object more especia y to improve the method of connecting the end blank to the body ortion of the receptacle, whereby said end b ank may be quickly secured to the body portion by a joint or seam, that will securely hold the parts together, so that liability of the parts being separated in hanor in trans ortation, is avoided, which joint or seam so may be made perfectly hermetic if desired.
A furtherobject of the invention is to provide a -method of connecting the closing blanks to the body of a receptacle wherein the arts ma be interlocked b the use of simp e expedlents and wherein t re is little or no wear upon the assembling mechanism, and furthermore, wherein the steps are few in number and quickly performed so that the in a given time.
The invention consists in the novel steps hereinafter described and set forth in the claims.
In the drawings which showby .way of receptacles may be made large quantities.
illustration a receptacle made by the present improved method:Figure 1 is a sectional view showing the receptacle body and theclosing blanks before 'bei applied to said body. Fig. 2 is a sectional view of one end of the receptacle wherein a slight amount of pressure has been used in joining the end lank to the body portion of the receptacle, so that said end blank may be removed if desired. 3 shows a sectional view of the end of a receptacle wherein considerable pressure has been used in joining the parts andthe body portion of the receptacle has been crowded entirely into the curl so that the parts are firmly locked together. Fig.4 is an enlarged sectional view of the seam or joint shown in Fig.3. Fig. 5 is a view similar to Fig. 4, wherein a sea material is used so that the seam or joint is made hermetic. Fig. 6 shows in section a seam for a plane of the closing bla receptacle with both inner and outer seal.-
Fig. 7 is a detail sectional view showing the closing blank with thezcompletely curled edge and a sealing material therein as the same is about to be applied tothe can body.
' In out my improvedmethod, I form the body 1 of the receptacle in the usual manner and when making-a round receptacle, the sheet metal ismerely rolled into a cylinderthe meeting edges overlapped and soldered or otherwise secure I The outer- ends 2 and 3 of the cylinder, are 30w ready to receimhle ct) onotr uirean er enor re aration fdi the recegtion of said zil ds ing b an s. The closing blank has a portion-.4 formed of practically the same area as the inside cross sectional area of that portion of the bod V of the'receptacleto which it is. to be a p 'ed. Said closing blank is formed with a sage 5 which extends laterally from. the portion 4- and is bent outwardly and then downwardly blanks and and inwardly: and then upwardly to form acurl 6, which extends entirely around the closing blank. I The inner edge of the curl 6 is slightl spaced from the flange 5; The closing blank is placed on the outer edge of the be y rtion of the rece ifacle, so 'that the e e oifhe rece tacle whic is straight enters tween the ange 5 and the inner edge of's'aid curl 6. Pressure is now applied to the closing blank or to the .receptac e so that the arts are forced together and the edge of the lied. or-. tion of the receptacle is bent by means 0 the curl in the closing blankso that the parts are interlocked. This pressure is preferably a plied in-a direction at ri ht angles to tli nlr and. the entire lank forced. on to the body portion of the receptacle at one time, although it is obvious J that thepressure may be applied in any other way that will secure the result desire The curled flange on the ole blank serves as a die to curl the edge oi the portion of the receptacle.
16o d i.
In ap lying e pressure, the closing blank ma be backed up with a suitable block whic if desired,
may be so formed as to conform to the outer surface of the curled edge on the clo ing.-
blank. From my method of jo' the clos' blank to the body portion of 't ere-1. ceptac c, it will be noted thatthecurledledge on the closing blank serves as a die to curl the therefore, the wear incident to the moving 1rd edge of the body portion of the receptacle and I of the raw edge of the sheet metal upon the curlingA die isreceived by the closing blank and t e supporting block for the closing blank, receives little or no wear.
By a. plying the closing blank directly to the b0 y portion of the receptacle, I am thereby enabled to use a great deal of pressure inassembling the parts, and for this reason, the curled edge on the flange of the closing blank may be made approximately of the same size as the seam, or joint used ordinarily in closing receptacles and therefore, after the parts are assembled, no further pressure is required to close the seam or joint between the parts.
It will be noted that 111 method may be used to apply closing blan s to both ends of the body of the receptacle, and thus com plete the entire rece tacle or the method ma be used to form-t e bottom of the receptac e, while other means is used to place the cover on the same. While I have referred to my receptacle as being cylindrical in shape, it is very evident that said receptacle may be rectangular or of any other shape. I
If only a small amount of ressure is used I in assembling the parts, the ody portion of the can will extend only a slight distance into the curled ed e on the closmg blank as shown in Fig. 2 and the parts thereby will be locked together.
B this form of construction, a suitable imp ement may be ap lied to the cover of the closing blank an the same removed from the body portion of the receptacle. When however, it is desired to form a permanentseam between the parts, considerable pressure is applied and then the ed e of the body portion of the rece tacle wi extend around into the curled e ge on the clos ing edge as shown in Fig. 4 and the parts thereby firmly interlocked, so that they cannot be removed Without practically destroying the closing blank.
When it is desired to hermetically seal the receptacle, I may place in the curled edge of the closing blank a suitable sealing material 7 (see Fig. 5), and as the body ortion is forced into the curled edge of said closing blank, the sealing material will effectively seal the joint thereby providing a seam or joint which is perfectly hermetic, or if desired, a sealing material 8 (see Fig. 4), may be applied to the joint after the parts have been interlocked.
The invention in its broader aspects is not limited to the formation of the particular receptacle herein disclosed, nor to any particular formation of receptacle, nor to any particular form of closing blank, as changes may be made therein without departing from the main principle of the invention, and without sacrificing its chief advantages.
Having thus articularly described my invention, what claim as new and desire to secure by Letters Patent, is: 1. The method of forming sheet metal receptacles, which includes the formation of a finished closing blank, with a com letely curled edge, placing said blank upon t e uncurled edge of the receptacle body, with the edge thereof extending into said curl, applying pressure so that the closing blank is g1ven a movement relative to said body portion, the curled edge of the blank causing the edge of the body portion to be curled and interlocked with said curled edge oil the closing blank.
2. The method of forming a sheet metal receptacle which includes the formation of a finished closing blank with a completely curled edge, providing said curled edge with a sealing material, placing said blank upon the uncurled edge of the receptacle body with the edge thereof extending into said curl, applying pressure so that the closing blank is given a movement relative to said body portion, the curled edge of the blank causing the edge of the body portion to be curled and interlocked with said edge on the closing blank.
In testimony whereof I affix my signature, in presence of two witnesses.
