WINTH BOP C. KELLOGG,'OF WILKINSBURG, PENNSYLVANIA, ASSIGNOR TO MAT I-IIEH N'S GRAVITY CARRIER COMPANY, OF ELLWOOD CITY, PENNSYLVANIA, A CORPORATION V or PENNSYLVANIA.

Original No. 1,226,222, dated To all whom it may concern.-

Be it known that I, Wm'rnnor G. KEL- gheny, State of Pennsylvania, have invented certain new and useful Improvements 1n Reversible Couplings for Gravit -Carriers,

of which the following is-a speci cation.

This invention relates to improvements in couplings designed for the 7' ends of ravity carriers or other devices employing si erails "the claims.

that are coupled together at their ends.

The invention consists generally in the constructions and combinations hereinafter described and particularly pointed-out in In the accompanying drawings forming part of this specification,-'

Figure 1 represents in plan view two sec tions of gravity carrier, separated fromeach other, but havin couplings adapted to have their members brought into engage- Inent,

. present drawing, but

Fig. 2 is a plan view,

Fig. 3 is a side elevation of female coupling members,

F 4 is a plan view,

one of the Fig. 5 is a side elevation of one of the same end of each ycarrler section with two female members and the opposite end of the male coupling members,

Fig. 6 is a side elevation showing two section coupled together with a support under the female coupling member,

Fig. 7 is a similar view showing the support under the male coupling member.

In the drawings 2, 2, represent the side rails of a gravit carrier section. These rails are provide with anti-friction rolls extending across from one rail to the other, with their ends journaled in said rails. The rolls are arranged. any desired distance apart. I have not shown the rolls in the have indicated their position by dotted line. It is thought that it will be unnecessary to shoW the details of the roller construction, as the same is not involved in my present invention.

Inlay prov'ide' the section with two male members, but I pre-I fer to provide each carrier sectionat each end with one female niem ber and one male this arrangement the rails are all exactlv alike, and may be made up in stock without regard to the side. of the carrier at which they are to be used. When the rails are placed in the carrier'sections, each section will be arranged with one male and one female member at each end.

I may permit the member to be on the lower end of the slots 5, and may then engage the hook formed by the recess 11 in the under side of the male coupling over this bolt. In this instance the end of the rail having the female cou ling member may be supported upon sultable supports and the rail having the male member will be hooked over the bolt in .the

I may, however, cause the bolt 6 forest in the 11 per end'of. olt will be 11 supported by a suitable support and the female member will be supported upon the end of said male member. I

'.'.lhe construction is exceedingly simple, be thoroughly practicable 'Any ltwo carrier sections coupled together and the 1 carrier section may be supported upon the end of the adjoining section.

The details of the co "tr uction may be varied without departing from my invention.

Iclaim as v y. invention: I 1-. A couplingg'for avity carriers, coma female mem r composed of bars through said slots, and a male member having upper and lower recesses forming a T-head, either one of said recesses, being arranged to engage therbolt er-tendingthrough the slots member, substantially as described.

for gravity carriers, com-' prising a female member having a vertical recess, a slot extending vertically through a bolt passing through said slots, and a male member arranged to project into said recess and hav-, inga T-head, either side ot the head being arranged to engage through the slots .in the female member, substantially as described.

A coupling, for gravity carriers, com-' prising a member having a vertically e r-I tending-slot with a stud arranged-1n sald slo t, and capable-of vertical adjustment whereby said prising a member-having a comprising a vertica tached to side rail members, and upwardlyin the female 5 prising upwardly and downwardly extendthe bolt extending therein a coiiperating member having upwardly and downwardly extending hooks, stud may be engaged with either of said hooks, and either carrier section support, or be supported by, the other member. 1 v V 4. A coupling, for gravity carriers, coming,vertically-adjustable stud, and a second member, having upwardly and downwardly extending hooks, either of which may engage said stud,whereby either member may support, or be supported by, the other member.

5. A coupling, for ravity carrier sections,

ly adjustable stud atand downwardly extending hooks attached to a side rail member, the upper hook engaging the stud ol' an, adjacent member when said stud is in its upper position and the lower hook engaging said stud when said stud is in its lower position, whereby either member may support, or be supported p by, the other member.

6. A coupling, for gravity carriersections,

comprising upwardly and downwardly extending hooks attached at one end of each ot-parallel side. rails, and a laterally projecting, vertically movable stud attached at the other end ofeach rail.

7. A coupling," for gravity carriers, coming hooksv arranged on" diagonally opposite rail-ends of carrier sections,

section, whereby when the carrier is set up either end of a section maybe connected with and support, or be supported by, the adjoining section.
