JOSEPH W. FRAZIER, OF NEW YORK, N. Y., ASSIGNOR TO ROSINE F. MONTGOMERY, OF SAME PLACE.
SPECIFICATION forming part of Letters Patent No. 469,444, dated February 23, 1892.
Application filed October 25, 1890. Renewed August 21, 1891. Serial No. 403,281. (No model.)
To all whom it may concern:
Be it known that I, JOSEPH W. FRAZIER, of the city and State of New York, have invented certain Improvements in Burden -Oarrying Devices for Use upon the Person, of which the following is a specification.
The objects of this improvement are to'increase the facility and comfort with which baggage, equipments, or other burdens may be carried upon the person of a traveler, hunter, or soldier.
The invention consists in distributing the weight of the objects to be carried by hangin g them, respectively, directly upon thelower extremities of suspenders composed of two front legs united to or formed in one piece with shoulder straps, which pass over the shoulders of the wearer, and are united to a single rear leg, and in the employment of a waistbelt for lightly holding said objects against the body and thereby preventing the movements of the wearer in walking, running, or jumping from imparting to the suspended objects swinging movements, which, if they were permitted, would result in the infiiction of uncomfortable blows against the person of the wearer. The more bulky portion of the load is carried in a skeleton frame, knapsack, or other receptacle, which is supported at the bottom upon the lower extremity of the rear Suspender-leg and is stayed at the top by straps passing across the shoulders and connected with the suspenders, which prevent the knapsack or otherreceptacle containing the bulky portion of the load from tipping backward. Those parts of the load which are heavy in proportion to their bulk I as, for example, ammunition -pouchesare hung upon the front legs of the suspenders by means of elastic connections composed of appropriately-arranged spiral springs. The knapsack or other receptacle for the more bulky portion of the load may also be supported by an elastic connection at the bottom to the lower end of the rear suspender; but this, although desirable, is not essential, because of the presence of the springs introduced into the connections between the front legs of the suspenders and the objects re-.
spectively hung thereon. Such springs by yielding case any vertical jarring movement By this invention there is provided a suspensory apparatus by means of which the total weight of the load is carried upon the shoulders of the wearer, and is so distributed that its center of suspension is in a vertical line near the longitudinal axis of the body and in a horizontal plane near the height of the shoulders. These results are accomplished without interference with the respiration or with the freedom of action of the limbs and muscles of the wearer during the acts of walking, running, or jumping, and without subjecting the wearer to the unoomforable blows which would be inflicted if the knapsack or other rear load were permitted to acquire swinging movements toward and from the body. Finally, the apparatus affords ample facilities for carrying a large variety of objects in positions where they are convenient of access and from or to which they may be easily removed or restored.
The accompanying drawings of a suspensory apparatus containing the improvements are as follows, namely:
Figure 1. is an isoinetrical perspective showing two ammunition-pouches hung, respectively, upon. the front legs of the suspenders and showing, hung upon the rear leg of the suspenders, the socket-frame for supporting the rear load. Fig. 2 is an isometric-a1 perspective of a skeleton frame for carrying bulky objects adapted for support upon a socket-frame hung upon the rear leg of the suspenders. Fig. 3 is a top view of the rear portion of the waist-belt and rear socketframe. Fig. 4 is an elevation, partly in section, of the rear socket-frame and adjoining portions of the waist-belt, showing the lower extremity of the rear suspender-leg connected to the said socket-frame. Fig. 5 is a rear elevation similar to Fig. 4, but showing the spring-tongue connected to the bottom of the knapsack or skeleton frame and deposited in its socket in the rear socket-frame. Fig. 6 is a transverse vertical section of the rear socket-frame, showing in elevation portions of the waist-belt and suspenders and exhibiting a knapsack supported upon the rearsuspenderleg. Fig. 7 is a longitudinal section illustrating the mode of connection of the shoulderstraps with the suspenders, which is shown in isometrical perspective in Fig. 1.
The drawings represent the suspenders A composed of the front legs A A, each of which is made extensible by means of the return bend and buckle A and each of which is provided at its lower extremity with the hook- A The front legs are respectively united to or formed in one piece with the shoulder-straps A A which are adapted to extend over the shoulders of-the wearer and are united to the rear leg a, the lower extremity a of which is connected with a metallic frame, hereinafter called the rear socket-frame B, in which is formed a socket B for facilitating the support of the knapsack or other receptacle for the more bulky portion of the load directly upon the lower extremity of the. rear Suspender-leg a. The socket-frame B is composed of the metallic strip 1), preferably leather-covered, the central portion of which is outwardly offset to form a recess with outwardly-flaring side walls I) b, united to a rear wall 19 which is parallel with the main portion of the metallic strip 6. A vertical partition b has its vertical edges brazed, riveted, or otherwise secured to the flaring side walls I) b, respectively, and serves as the inner wall of the socket B. The ends 11 b of the metallic strip bare bent inwardly and have riveted to them the vertical bands b 12 respectively, which serve to loosely clasp the waist-belt 0 against the inwardly-turned ends 13 b of the strip b. The Waist-belt is provided in front with the usual clasp O.
Within the bight of the flaring bends of the metallic strip 1) are secured the vertical cylinders 1) 19 in which are inserted the vertical legs 19 19 which are affixed to or formed in one piece with the horizontal bar 19 to which the lower extremity a of the rear suspender-leg is connected. Although not absolutely essential to the successful working of the suspensory structure, it is preferred to introduce within the cylinders 19 b the expanding spiral springs b 5 which abut at their upper ends against the perforated heads of said cylinders and at their lower ends against the transverse keys or nuts 19 19 re spectively, applied to the lower extremities of the vertical legs b o The quality of elasticity is thus introduced into the device con necting the socket-frame B with the lower extremity of the rear Suspender-leg a.
The ammunition-pouches D D are carried, respectively, upon the pouch-frames D D. Each pouch-frame is composed of the metallic strip d, which is preferably leather-covered. The opposite ends d cl of the strip 61 are bent inwardly and secured, respectively, to the vertical cylinders d 01 and have riveted to them the bands (1 d which serve to loosely clasp the waist-belt 0 against the inwardlybentends d d. WVithin the cylinders 61 (l are deposited, respectively, the expanding spiral springs 62 d, which abut at their upper ends against the perforated heads of the cylinders d d and at their lower ends against the transverse keys or nuts d (1 applied, respectively, to the lower extremities of the vertical legs d d, which are united to or formed in one piece with the horizontal bar 01 to which there is attached the eye 01 for engaging one of the hooks A with which the lower extremities of the front suspender-legs A A are respectively provided. The more bulky portion of the load is carried in the rear of the person and may either be contained within the knapsack E, as illustrated in Fig. 6, or within the skeleton frame F. (Illustrated in Fig. 2) The latter preferably consists of a metallic base-frame F, to which is pivotally connected on the side next the body of the wearer a short upright metallic frame f and upon the opposite side a longer upright metallic frame F3. The upper extremities of the two upright frames respectively are provided with the strap-eyes f f and F F Flexible stay-straps G G are permanently secured to the strap-eyes f f respectively, and are led upward therefrom and over the load contained within the skeleton frame through the strapeyes F F and thence forward over the shoulders of the wearer to their points of attachment to the suspenders, such attachment being effected by the engagement of the hooks g g, with which the free ends of the straps G G are respectively provided, with the vertically-adjustable links H H, arranged on the front legs of the suspenders. Each of the said links consists of a rectangular frame It, provided with a central cross-bar h, from which there project laterally two short pins 71. 712, which are adapted for insertion through holes punched in the suspenders. The suspenderstrap in each case is led over the cross-bar h but under the bars of the rectangular frame, which are parallel with the said cross-bar. The front legs of the suspenders are each provided with two rows of holes 0 O'toprovide for the adjustment of the'links H H at different heights.
Instead of making the links H H vertically adjustable, they may be permanently secured to the legs of the suspenders, as illustrated in Fig. 6, in which case the stay-strap for leading over the shoulder and connecting with the load in the rear of the person will be constructed like the stay-strap I, (shown in Fi g. 6,)
which, as will be seen, is made extensible by means of the return-bend v) and buckle i. The stay-straps are intended simply to hold the load at the rear of the person, so as to prevent it from tipping backward. The Weight of such load, whether it be contained in a knapsack or in the metallic frame F or other receptacle, is directly supported upon the lower extremity of the rear Suspender-leg. To that end the bottom of the knapsack or the bottom of the skeleton frame or other receptacle, as the case may be, is provided with a tongueJ, which is adapted for deposit in the socket B.
Although not essential, it is preferred to pivotally connect the tongue J with the bottom of the knapsack, skeleton frame, or other weight-carrying structure, and to employ, in connection with said tongue, a torsion-spring,
by the influence of which the tongue, when removed from the socket B, will be rocked against the bottom of the weight-carrying structure, as illustrated in solid lines in Fig. 2, in which, as will be seen, the tongue J is looped around the horizontal bar K, to which there is applied the spiral spring 7c, the central portion it of which bears against one side of the tongue J, while its opposite ends are affixed to the lugs L L, projecting downward from the inner corners of the base-plate F. The lugs L L may, however, be arranged to project downward from the base-plate midway between its front and rear corners, as illustrated in Fig. 6, in which they are represented as so applied to the bottom 6 of the knapsack E. In such case the tongue J will be bent to a right angle, as shown in Fig. 6, so that when detached from the socket B its torsion-spring 7; will cause its vertical portion to be rocked upward against the outer side of the knapsack E, approximately to the position in which it is represented in dotted lines in Fig. 6. Vhen the tongue is-inserted in the socket B, the resultant effect of the torsionspring 71; is to lightly press the lower portion of the knapsack E or of the skeleton frame F, as the case may be, toward the back of the wearer, so that, although the waist-belt is not clasped tightly around the body,there will be no opportunity for violent lateral swinging motion to be communicated to the lower part of the knapsack or frame by the movements of the wearer.
When a knapsack is employed, the staystraps may be connected with a buckle-eye E, affixed to the top of the knapsack, as illustrated in Fig. 6.
If desired, the socket B may be made of sufficient width to permit the insertion therein of the tongue m of a haversack or pouch M, as illustrated in Fig. 6.
