This invention relates't'o improvementsin packsr andpack carrying frames; and has-reference moreparticularly to such packs as those carried by hunters, sportsmen, soldiers, prospectors, etc., for transporting'duffel, or supplies, and-which comprises a frame structure equipped with'a harness wherebyit may be strapped-to the wearer's back,

and a; duffel bag, orsack, that is adapted to be attached to the frame and in which such things as: supplies; bedding and camp equipment, referred to as'duffel, may be carried.

It is the principal object of this invention to provide an improved type of frame structure; one that is exceptionally lightinweight, strong and durable in construction and which will spring or yield in conformity with movements'of the body: Also, a frame to which the duffelbag may be easily afiixed and from which it maybereadily removed without requiringits being unpacked.

Still further objects of the invention residein certain details of construction of the duifelbag; the details of construction of the frame struc' ture; the means for attaching the bag: to the frame, and the combination of" the variousparts intheir functional'use.

In accomplishing these and'other objects of theinvention, I have provided the improved details; of construction, the preferredlforms of which are illustrated" in the accompanying drawings; ,wherein Fig. 1 is aperspective view of the ied by the present invention.

Fig. 2 is a central, vertical section of. the pack, showing, the framev and dufiel. bag as applied thereto.

Fig. 3 is a. cross, sectional view online 3-3 in. Fig. 2.

Fig. 4 is a perspective view of the frame.- structure with the duffel bag removed therefrom.

Fig. 5 is a perspective view of the duffel bag removed from the frame and showing the back side thereof and the attaching tunnels.

Fig. 6 is a cross sectional view taken on line 56 in Fig. 2.

Fig. 7 is an enlarged detail of a portion of the bag showing its means for attachment to the frame.

Referring more in detail to the drawings First, it will be explained that this particular type of pack is designed to be carried on a person's back and to be affixed in place by means of a harness comprising a pair of straps that have pack embodends fixed to the upper part of the pack frame,

with ends thereof arranged to be passed over the wearers shoulders; thenunder the arms and again" fixed to the frame.

The duffel bag isin the nature of a.- sack, and

ofasize to permitit tdcarry a substantial amount of supplies'or' duffel, and which is removably applicable to the frame without requiring that it be unpacked.

The present: invention deals with the novel details of construction of the frame; the details of'construction of the bag; the meansfor attach-- ing the bag to the frame and: the combination and relationship of the parts in use.

Referring more particularly: to Fig: 4- of the drawings, which illustrates, in perspective, the 1. frame structure of the pack; this is constructed of heavy spring steel wire, and it comprises a central, vertical frame: portion which. is formed from a continuous piece of'wirebent back upon itself to form a rounded upper endloopdesignated at 10: in Fig. 6, with the opposite side legs II and H extending dbwnwardly from the end loop; in spaced relationship-t0 the full-length off the frame. In a frameof normalsize, the spacing of the legs I |-ll is approximately six inches apart and the length from the loop end to the lower end's of the. legs is approximately two feet.

Attached tothe central frame portion, comprised'by the loop l b" and legs l lIl-, across theupper" and lower end portions: thereof, are two transverse frames; each of these comprising two horizontal coextensive wires I12 and" I2, spacedapproximately four inches apart, and joined at their ends by'vertical" members l3. These frames are located symmetrically with respect to the central frame; and'the opposite-ends of each extendabou-t five inches beyond each side of the central-frame portion.

Welded to the outerends of the cross frames;

parallel with-- the connecting wires" are vertieali tubular sleeves I 5'. Also, as will be observedbestby reference-- to" Fig. 6-, a cross wire [4 is fixed between the frame legs Hi| and to the upper cross wire l2 of the upper transverse frame, with its central portion offset upwardly from wire l2, and extended about this wire is an elongated strip of canvas or the like, forming shoulder straps l9 and I9, adapted to be passed over the shoulders of the wearer, then downwardly in front of the shoulders and beneath the arms. Attached to the lower ends of these straps I9l9 are extensions 2| of reduced width adapted to be tied at their lower ends about the bottom cross wire of the lower transverse frame as will be understood by reference to Fig. 6.

With the frame so equipped with this harness,

erence to the center frame. In order that theframe andpack may be carried without resting directly against the wearers back, I have extended opposite end portions of cross straps 24 about the sleeves l5. Preferably, there are strips of canvas or the like with their ends joined by lacings as at 25 whereby the straps ar drawn taut. Thus, when the straps are taut, they will rest against the wearer's back and the wire frame and the pack suspended therefrom will be held out from the wearers back. r

The dufiel container or bag, which, in its preferred form, is as shown in perspective view in Figs. 1 and 5, may be in the nature of a sack or bag, of anysuitable material. Preferably this bag would be formed with a back wall 26,,front wall 21, opposite side walls 28-28 and open at,

its upper end. The back member of the bag is extended to form a cover flap 29 which may be drawn over the open end of the bag and downwardly of the front wall, and it is equipped with attaching straps 3I3,| applicable to buckles or loops 32 that are fixed to the front wall of the bag.

By reference to Fig. 5, it will be observed that onthe back wall of the bagalong or near its opposite side edges, are tunnnels or hems 34, stitched thereto. These extend vertically and are in the nature of open endedtubes. V

The length of the tunnels 34 or hems that are sewed to the back of the bag, is equal to the vertical spacing of the cross frames and sleeves l5 that are fixed thereto. Also, in their horizontal spacing, these tunnels, correspond to the length of the cross frames, or distance between the sleeves at their opposite ends.

Also, it will be seen that sewed to the upper end of the back wall at the center thereof, is a downwardly opening pocket 35 which extends up above the top end ofthe bag andis adapted to receive the looped upper end portion In of the center frame therein as a means of attaching and suspending the bag from the frame.

In applying the duffel bag to the frame, the pocket 35 is first applied over the upper looped end portion ll! of the center frame, then the tunnels are registered between the tubular sleeves l5 that are fixed to the opposite ends of the cross frames and rods 40, as shown in Fig. 6, are passed down through the sleeves and through the alined tubes at the ends of th cross frames .50 as to attach the bag to the frame. The rods as at 4| to keep them fromworking down and from the sleeves.

Packs and pack forms of this kind may be made in various sizes and the proportions might be varied somewhat as desired.

Such packs are exceedingly light, easy to carry, strong and lasting. The pack may be easily and readily removedfrom the frame merely by pulling the rods or pins 40 up from the tunnels, and then lifting the bag off the loop l0.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent is 1. A pack of the character described comprising a frame structure with means for securing it upon the back of a wearer, and a pack sack; said frame structure comprising a central vertical frame member mad from a single piece of spring wire bent to form a rounded upper end loop and two spaced vertical legs; cross frames fixed to the legs of the central frame member with opposite end portions extended equally to opposite sides thereof; tubular guidemembers fixed to the ends of the cross members; said tubular guides at'corresponding ends of upper and lower cross members being in axial alinement; said pack sack having a back wall with tunnel strips fastened thereto for registering between alined guide tubes,-a downwardly opening pocket fixed to the back wall and containin said upper end loop of the central frame; therein, and pins extended through alined guides ,and tunnelstoattach the sack to the frame; said pins being removable to release the sack and; said sack being adapted to be lifted to release said pocket from the upper end loop of the central frame member.

2. In a pack ofthecharacter described, a back frame having a body harnessattached thereto,

said frame comprising a central vertical portion formed from a single length of spring wire bent to form a rounded upperend loop and two spaced legs, upper and lower cross frame portions welded to the central frame member at vertically spaced relationship and extended equally to opposite sides thereof; each cross frame portion being made from a single length of spring steel wire bent to form upper and lower cross members and opposite end members, tubular guides fixed to the end members of both cross frames, and cushion" strips extended'about and drawn taut between the tubular members of each cross frame, and a pack sack formed at its upper end Witha downwardly opening pocketpadapted to receive the rounded upper end of the central frame thereinand having tunnel strips fixed thereto for registering between the alined tubular guides ofthe cross frame members, and attaching pins removably applied through alined guide tubes and tunnel strips. j V
