Appncation mea December s, 1930. l serial No. 500,754.

` This invention pertains to an improvement in pneumaticdispatch carriers and more particularlyrelates to a method of attaching a `skirt to one end of the carrier and to the resulting structure.

Pneumatic carriers having the type of skirt'shown in the patent to Jennings,fNo-. 1,773,360, August 19, 1930, are objectionable due to the fact that the stitches securingthe skirt to the carrier are exposedv and come in contact with the carrier tube 'during the travel of the carrier and consequently quickly wear out. A further objection lies inr the method4 of attaching such skirt portions to the carrier body in that the resulting structure does not o er any protections to the end bumpers andcover when traveling around bends or curves in theV tubes. Consequently premature repairs and replacements are necessitated and the life of the carrier is appreciably shortened.

It is the object of this invention to provide a simple and' eliicient method of attaching the skirt portion to the body of a carrier which willproduce a durable structure and provide the necessary protection to the end and bumpers of the carrier, which will vprotect the stitches or other means securing the skirt to the carrier, and which is generally superior to the old type skirt portions.

Further objects and advantages will be apparent as attributes of this method of attaching such skirt portions to the carrier body and the resulting structure herein shown and j described in connection withthe accompanying drawings which illustrate this invention by way of example and in which; y Fig. 1 is a side elevation partly in section of one end of a carrier embodying this invention;

Fig. 2 is a front elevation of a section of the carrier shown in Fig. 1; and l v Fig. 3 is a plan view of the carrier shown in Fig. 2 the coverV being closed.

Referring to the accompanying drawings, and more particularly to Figs. 1 and 2 thereof, the carrier maybe of any suitable type, whether the access be at the side or at one end, butisv here shown, for example, as having abody portion .or shell l of oval cross section and the' access at its end. y yA suitable cover 2affording access to the interior of the carrier is secured to the body portion 1 by the hinge 5 and normally locked inplace by a strap 6 and a fastener 8. The bumpers 3 and 4 are secured to the cover 2 by the riv- 'ets 7.

The skirt 10 comprises a substantially recytangular piece of leather or other suitable material having a length preferably greater than the circumference of the carrier in order to permitthe sides 12and 13 to overlap v rather than butt,` each other. Preferably the sides 12 and 13 are skived to form a skived joint as indicated by numeral 15 in Fig. 1, rather than a lapped joint. l At predetermined points adjacent to each ofthe edges or sides 12 and 13 circular holes 16 are provided for the reception of rivets 18. Similar j holes are also provided at the center of the yskirt between the sides 12 and 13 for the reception of the rivets 18a. Preferably the end 11 is also skived in order to provide a skived oint with the body portion las indicated y numeral 14 inFig's. 1 and 3. Y

The skirt 10 having beenthus prepared is circumposed around the end "of thepcarrier body with the skin or finished vside, facing inwardly in the position shown by the dot and dash `lines in Figs. 1 vand 2, and with the endl 17 engaging eXteriorly the body portion adjacent the opening therein. While the skirt portion is being held in this position, the ends l 5a of the hinge and 6a of the fastener strap arey inserted between tht-skirt and the body por-' tionA on op osite sides ofthe carrier body, as shown in ,s ig. 1. While being held in this position the portion Vo f the vskirt adj acent the end 17 is stitched or otherwise fastened to the carrier body around'its entire circumference.` `As shown in Fig. 1, this stitching 17L also secures the fastener strap and hinge r*to the body portion. j

A stifener plate 19 comprises'a rectangular piece'of sheet metal, forexample, zinc, or other rigidmaterial, having a length equal to the circumference o f the body portion 1 and provided `with holes at predeterminedpoints for the reception of the rivets 18 and/18% The stiifener plate is circumposed yabout'the body portion subjac-cnt to the end 17 of the skirt 10 and may be heldin position by the rivets 18v and 18a which, preferably at this stage of the assembly, are inserted from the interior of the body portion 1. The free end 11 of the skirt is then pulled down over the stitching 17a, forming a protuberant pocket 20, as shown in 2, and thereby bringing the finished surface of the leather to the outside. This step may beeasily accomplished as the overlapping sides 12 and 13Y at thisstage are free and do not oder the resistance they would if cemented together. At this stage it is preferable to cement thesides 12 and lof the skirt portion. The pocket 20 is then filled with goats7 hair, leather scrap or other suitable material, and is uniformly packed to provide a protuberance or swell of a desired contour around the circumference of the carrier body with the exception of the portions thereof through which the rivets 18 and 18@L project. The skirt portion is then stretched or worked into position in order to permit the rivets 18 and 18a to pass through the openings 16. Washers 21 are applied to the ends of each of the rivets 18 and 18a and secured thereto in the usual manner. Having thus provided the desired contour to the skirt portion, the end 11 is stitched or otherwise secured to the body portion, forming a skived joint therewith as shown by numeral 14 in Figs. 1 and 2. Y

From the foregoing it is apparent that this method of attaching the skirt to the carrier produces a structure wherein the stitching 17 or other fastening 'means is completely concealed and thus protected from wear and damage thereto which would result vfrom being exposed. It is further apparent that the stitching adjacent the end 11 will be similarly protected due to the yprotubera-nce of the adjacent skirt portion. Likewise, the rivets 18 and 18a will be protected and prevented from coming in contact with the tube through which the carrier travels.

A'further feature of this structure is that the protuberant portion of the skirt adjacent the cover will protect the bumpers 3 and 4 when entering a terminal `or other receptacle and also will prevent the bumpers from coming in contact with the` carrier tube when travelling around the bends or curves therein. `While I have shown and described one desirable embodiment of this invention, I wish it to be understood that the application of this method is not limited to the type of carrier here shown, that in practicing this method it is not necessary to adhere to the precise order of steps herein recommended, and that various changes and modifications both in the order of steps and materials employed can be made without departing from the spirit and scope of this invention as set forth in the appended claims.
