This invention relates to improvements in I horse collar oapsor pads and a method of producing the same. Most collar manufacturers demand acllar-cap which is exeeptionally hard and stifi; such aoap being-p oducedby molding the "blank of leath'en-from which the cap is formed, under highpressure; whereby the material-is eoinpressed 'to such a degree that it'fvvi lil; as stated, 'be exceptionally' hardandstifi'; such iaxta however, presents the disadvantage, na1nely,that in riveting the Cap tothe'collafl therivets are liable to break, through the "cap; thereby rendering the same unfi't for use. Thisis v due to the faot that it is necessary that asits object to provide a cap which ma be formed under such degree of pressure that itjwi'l'l possess any desired degree-0f 'ha'rdness' and stiffness such as deniandedhy the manufacturer, "and will, at the same time, be

adapted to be, riveted to the collar Without any likelihood whatsoever of s, the rivets 'lire'aking througlrthe' cap; so that the rivets my he applied-with practieally the same facility as though theeap were'of-asofiter and iiiere pliable nature than that demanded.

"Another object of the invention is to evolve novel "method "whereby a eapripossessingthe advantages above outlined, ma he Conveniently p roduce'd at a low host and, "in acunae greater cost than that involved in the production ofthef ordinary eapjwhich presents the disadvantages referred to.

In the: draWings', tl 1e numeral 1 indicates the collar cap which is, asusuaLofisubstantially" antic lasti'o f orni and which comprises the usual upwardly direetedi front portionifl: and the 13 3 portion 3, andthe depending side portionsor flaps 4;. Ordinarily, in the nianu tacture of horse 1 icol lar caps,\ leather blanks out "to proper i'narginal contounare subjected to pressure in a 'nioldi'so. as to "pant to the blanks:thefdesired ffiomn and, at

"the same-time, so compress" and oompact'the leather eohiprising the blanks as to "render the leather exceptionally stili and: hard, .jthe neral "demands of :the n1anufaoturersof hor'se col'larsheing that the caps purchased by themshall possess these qualities, As

heretofore en alained', however, such ageap presents the disadvantage that, in fastening "the sa ine to the collar, if the securing riivetsq are so firn-i'lvdriven as to 'bringztheir heads substantiall to the surface: of the Leap, the

rivets will hreak through ithe cap, thereby lender'ing the saineunfit for use; illhehieap substantially (on lustra ting a slight modification of tzhe invene'nibodyingthe present inventioniis likewise molded under pressure to the required form, but the lnethod iof the present invention differs very niateiqialfly from the method ilieretofore follovred 'iin that whereas heretofore it has beencustomary to exert high pressure against all portions of the area of the cap so that the same will be of uniform density and hardness throughout its entire area, the blank, by the method of the present invention, for a. definite portion of its area, is not subjected to pressure, thereby providing the finished product with an uncompressed and comparatively soft portion through which the necessary securing rivets may be readily secured and into which the heads of the rivets may be forced and their heads brought substantially flush with the surface of the cap. This portion of the cap, illustrated in Figures 1 and 2 of the drawings, is indicated by the numeral 5, and in this embodiment is of substantially rectangular outline and extends with its longer dimension transversely of the cap substantially at the juncture of the front portion 2 of the cap with the intermediate portion thereof. Referring now to Figure 2, it will be observed that the rivet, which is indicated by the numeral 6, is adapted to be readily secured through the portion 5 of the cap inasmuch as this portion is of substantially the same density as that of the original blank, which blank, before compression, is more or less pliable. It will also be observed by reference to the said Figure 2, thatwhen 'the'cap is riveted to the flap of the collar,

which flap is indicated by the numeral '1", the

heads of the rivets 6 may be brought substantial'ly flush with the surface of the uncompressed portion or area 5 of the cap, thereby insuring against any rubbing of the horses neckto cause sores, which is liable to occur where the rivet heads project to a greater or less extent beyond the surface of the cap. It will be observed by reference to Figure 1, that the dimensions of the uncompressed portion 5 are such that this portion is adapted to accommodate two or more rivets, usually two, which are all that is'necessary to secure the cap to the collar.

In that embodiment of the invention illustrated in Figure 3 of the drawings, the cap,

which in this figure is indicated in general by. the numeral 8, and which is in itself of the same form and same degree of stiffness and hardness as the cap previously described, 18 subjected to pressure except for two or more circular, areas or portions which are indicated'by the numeral 9, which areas or portions are left uncompressed and therefore, possess the original softness of the blank from which the cap is formed. These circular portions 9 are, of course, located and arranged in accordance With the proposed location and arrangement of the securing rivets, each rivet being secured through an individual one of the said portions, and the heads of the rivets, in-the riveting operation, being broughtclose to the surface of the respective portions, as in the first described embodiment. It will be understood, of course, that the invention is not limited to the number of uncompressed portions which may be provided in the cap,

as this will depend upon the number of rivets .hardnessas the previously described caps.

However, in this embodiment, pressure is exerted, during the moldlng operation, against the under side of the cap but no obstruction is present, during the molding operation, at the upper side of the cap, so that the uncompressed portion, which is indicated by the numeral 11, is offset upwardly, thereby providing a shallow recess 1:2 at the under side of the cap, in which the head or heads of the rivetor rivets may be accommodated, thereby bringing them well within the surface ofthe under side of the cap as awhole. The uncompressed portion 11 may have the general shape of the portion 5 of the first described embodiment of the invention, or it may have the shape of the uncompressed portions9 of the embodiment shown in Figure 3.

Figures 5, 6 and 7 of the drawings illustrate the molding or forming dies which are employed in producing the caps shown in .Figures 1 and 2 of the drawings, and in the said Figures 5, 6 and 7, the die members are indicated, one by the numeral 13 and the other by the numeral 14. These members neednot differ materially from the ordinaryniolding die members which are employed in the manufacture of horse collar caps, except in the respects which will be pointed out. The upper side of the die member 13 is provided with a forming surface 15 which is of anticlastic form, and the under side of the die member 14, indicated by the numeral 16, is of corresponding form, so that when a cblank of leather is placed between the members and the members are brought together and pressure exerted, in the manner, andfiunder the conditions attending the molding or shaping of the ordinary collar cap, the leather blank will be caused to assume the desired contour. Ordinarily, however, the pressure exerted upon the leather blank issubstantially uniform throughout all portions of the area of the blank and is sufficiently great to insure of the completed article being exceptionally hard and stiff throughout all portions of its area. In accordance with the present-invention, and in this embodiment thereof, the molding face of the die member 13 is formed with a recess or depression 17 whichis of a contour and dimensions corresponding substantially to the contour. and dimensions of the uncompressed portion with which the completed cap is to be provided, and this recess is, furthermore, of a depth somewhat greater than the distance at which the surface of the portion 5 of the cap is locatedv beyond the under surface of the cap. it i will now be evident that whenthe leather blank is disposed between the die members and the die members are brought together in the usual manner, all portions of the area of the blank will be compressed to a degree to render the completedarticle exceptionally hard and stiff, except that portion of the blank which extends over the open side of the recess 17 is not subjected to compression. As a consequence, as a result of the molding or forming operation, all portions of the leather blank will have been subject ed to great pressure except that portion through which the rivets are to be secured and consequently this portion will retain its original soft and readily penetrable qualities.

. Figure 8 of the drawings, illustrates a die member 18 which does not differ materially from the member 13 except that instead of being provided with a substantially rectangular recess in its forming face, it is provided with circular recesses or depressions 19 which are of such dimensions and so arranged and located that the cap formed by the use of this die will be provided with the uncompressed portions 9 heretofore described and shown in Figure 3 of the drawings.

The mold or forming. die shown in Figure 9, comprises die members and 21 corresponding to the members 13 and 14 of the firstdescribed form, and in this structure. the member 20 is provided upon its forming face with a relatively shallow boss 22, and the member 21 is provided in its corresponding face with a relatively shallow recess 23 which, however, is deeper than the boss 22. The boss 22 and the recess 23 are so located that when the die members are brought together they will be opposite each other and consequently, a leather blank disposed between the die members and acted upon thereby will be provided with the ofiset uncompressed portion 11 and recess 12 heretofore described and as shown in Figure f the drawings.

Having thus described the'invention, what I claim is:

1. A horse collar cap of compressed I leather having a substantially uncompressed portion. for the passage of a securing element.

2. A horse collar cap of compressed leather having a substantially uncompressed portion providing a relatively shallow projecting portion presented at the under side of the article for the passage of a securing element therethrough.

3. A horse collar cap of highly compressed leather, the upper surface of which cap is substantially smootlnthe caphaving a portion of its area substantially uncompressed to afford. a relatively soft portion one side of which is presented at the under side of the cap and through which portion a fastening element may be readily secured with its head substantially embedded in the said side of the portion.

In testimony whereofI aifix my signature.
