GASKET-1,
Application filed November 8, 1926.: serial-11o. 147,079.
This invention relates to gaskets of the character adapted for use as packing around refrigerator doors, as a weather strip for doors, windows, etc., and for various uses where a seal is desired.
One of the objects of this, invention isto provide a gasket of the type in which a roll is closely confined by an envelope whose free edges are extended to provide a tackin lap but in which the tacking lap is secure an reinforced in a simple and effective manner. Another object is to provide a gasket of the character described which is simple in construction, effective in its action, neat 1n appearance, durable and economical to manufacture.
Further objects will appear from the detail description taken in connection with the accompanying drawing in which Figure 1 1s a section through a door and its 'amb illustrating the application of the gaset embodying this invention.
Figure 2 is a view sliowmg the method of ap lying such a gasket when turning corners. Figure 3' is a. perspective view showing. the method .employed in producing a gasket in accordance with one embodiment of thls 1nvention.
Figure 4 is the completed gasket. v
Figure 5 is a perspective view showing the method employed in producin a gasket in accordance with another embo iment of this invention.
Figure 6 is a view showing the completed gasket.
Referring now to the accompanying drawing and more particularly to Figure 1, A designates a gasket which is arranged for placement between the door B and the j amb C, as for instance in a refrigerator. The gasket has a tacking lap D through which fasteners such as tacks 1 may be passed to apply the same. The gasket comprises, generally stated, a roll 2 which is preferably of soft fibrous material such as cotton and enclosed b an envelope 3 which is preferably of flexible water proof material such as rubberized cotton. The free edges of the envelope are extended as shown at 4 to provide a tacking lap D.
In accordance with this invention the roll is enveloped so as to leave the free edges of the envelope extend to provide a tacking lap. A line of stitches 6 is then passed along the envelopeso asto closely confine the roll in order to provide a tight and yielding packing which will freely yield to form an effective seal and when pressure is relieved will return to circular shape. The roll now being closely confined, the extended edges of the envelope which form the ply of the tacking lap are now adhesively secured together.
In accordance with one embodiment of this invention as shown in Figure 3, these plies are vulcanized together, by either utilizing .a layer of rubber 10 placed between the plies or by utilizing the rubber covered surface of the envelope. This vulcanization can be secured in any suitable manner known to those skilled in the art and for illustrative purposes a pair of heated rolls llare shown, although there will be in practice a series of these rolls through which the extended edges 1 of the envelope pass. The object is to vulcanize these extended edges together to form in effect an integral tacking lap and the instrumentalities for securing thls result will be obvious to those skilled in the art. The complete gasket is shown in Figure 4.
In accordance with another embodiment of this invention as shown in Figure 5 the extended edges of the envelope forming the tacking lap are secured together by cement which is shown figuratively a phed by brush 12, although it will be un erstood that in practice the cement may be applied in'any suitable manner. This cement is preferably a water proof cement such as having a rubber base in order that it'will not crack when subjected to heat or moisture, After the surfaces have been cemented the extended edges may be secured together in any suitable manner as being passed through rollers such as 11, Figure 3, which need not however be heated although heating will be useful in certain cases and with certain cements.
The completed gasket can be provided with a series of stitches as shown in Figure 6, and comprising an outside line of stitches 7 and intermediate lines of stitches 8. These stitches serve the useful function of not only rinforcin the tacking lap but also preventin buckling, although it will be understood t at the gasketis entirely serviceable Without the stitches 7 and 8, especially when the tacking lap plies are vulcanized together. I In theapplication of this gasket the fasteners 1 pierce the tacking lap and secure the gasket in place. Where the tacking lap is ormed of plies vulcanized or adhesively secured together, this tacking lap will be stiffened not only transversely but also in its own plane; additional stiffness is secured by the lines of stitches along the tacking lap. In turning corners, as shown in Figure 2, the tacking lap is out 'or notched as shown at 9, Figures 4 and 6, so as to permit suchturning and the lapped portions can then be secured by a fastener as shown in Figure 2. The pro Visions of the inside line of stitches 6 not only permits this notching to be accomplished while still retaining the roll tight at the point of turning, but the initial confining of the roll by this line of stitches permits the ad hesive to be effectively applied and secured. The roll is, therefore, given its original shape and tightness by the inside line of stitches 6 and this roll is retained in shape and tight condition throughout the life of the gasket.
It is obvious that various other changes may beinade in the details of construction Without departing from the spirit of this invention; it is, therefore, to be understood that this invention is not to be limited to the specific details shown and described.
Having thus described the invention What is claimed is: i
1. A gaslret comprising, a roll, an envelope enclosing said roll and having its free edges extended to provide a tacking lap and an inside line of stitches passing through the en- .velope plies along said roll and-adapted to confine the same 1n order to provide a tight but yielding packing, said plies being adhesively secured together beyond said line of stitches in order to stiffen the tacking lap.
2. A gasket comprisin a roll, an envelope enclosin said roll and aving its free edges extended to provide a tacking lap, an inside line of stitches passing through the envelope plies along said roll and adapted to confine the same in order to rovide a tight but yielding packing, said p ies being adhesively secured together beyond said line of stitches and stitches passing through the adhering plies in order to reinforce the tacking lap.
V 3. A gasket comprising, a roll, an envelope enclosing said. roll and having its'tree edges extended to provide a tacliing lap and an insideline of stitches passing through the envelope plies along said roll and adapted to confine the same in order to provide a tight but yielding packing, said plies being vulcanized together beyond said line of stitches in order to stiffen the tacking lap.
1n testimony whereof I aflix my signature this 1st day oi November, W26.
