Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed May 20, 1911. Seria1 No. 628,401.

To all whom it may concern:

Be it known that I, HENRY L. Fninus, a citizen of the United States, residing at Harvard, in the county of McHenry and State of Illinois, have invented a new and useful Improvement in Swinging Tracks and Booms for Litter-Carriers and the Like, of which the following is a specification.

My invention relates to certain new and useful improvements in a swinging track and boom for litter-carriers and the like, and is fully described and explained in the specification and shown in the accompanying drawings, in which:

Figure 1 is a side elevation of my improved device; Fig. 2 is a horizontal section on the line 2 of Fig. 1; Fig. 3 is a detailed side elevation of the parts adjacent to the boom pivots; Fig. 4 is a top plan of the parts shown in Fig. 3; Fig. 5 is a vertical section on the line 5 of Fig. 4; Fig. 6 is a transverse section on the line 6 of Fig. 1; Fig. 7 is a top plan of the parts shown in Fig. 6; Fig. 8 is a vertical transverse section on the line 8 of Fig. 7; Fig. 9 is a section on the line 9 of Fig. 3; Fig. 10 is a horizontal section on the line 10 of Fig. 1; Fig. 11 is a transverse vertical section on the line 11 of Fig. 10; Fig. 12 is a similar section on the line 12 of Fig. 10; Fig. 13 is a side elevation of the guy-supporting device; Fig. 14 is a section on the line 14 of Fig. 13, and Fig. 15 is a transverse section corresponding to Fig. 9 through a modified form of the boom.

Referring to the drawings, 16 is a barn wall provided with a door-opening just above which is a stationary pivot-member 17 arched to embrace a barn-door hangerrail in accordance with what is now approved practice.

18 and 19 are two swinging hinge-members provided with ears 20 engaged by a pivot-pin 21 whereby they receive pivotal support from the stationary hinge-member- 17. The two

members

18 and 19 are each, in the preferred form of construction, rightangled in cross-sections to embrace angleirons which together form the boom. The

members

18 and 19 are provided with laterally-extending ears 22 and are held together by vertically-extending bolts 23.

The two angle-irons, of which the boom proper is composed, are placed with their open sides together and their angles apart with a slot between them vertically. The

. various devices which hold these two angleirons in a solid and substantial construction, are formed so as to embrace their outsides, after the manner of the

members

18 and 19 of the swinging hinge-members, and these various devices are held together by bolts passed between the angle-irons and clamping the various embracing devices onto the separated edges thereof, with the result that the angle-irons are pressed to gether and thus squeeze against the various bolts so that the strongest possible construction is obtained.

The devices which hold the angle-irons together are all, or practically all, so arranged as to serve other purposes as well. Thus the track is supported by brackets 24, each in the form of a bolt having a shoulder 24* below the angleirons of the boom and having its upper end passed therebetween. This bracket construction is fully illustrated in Figs. 3 and 9, where it will be seen that above the shoulder 24 of each bracket is a boom-clamping member 25 embracing the outsides of the angle-irons thereof, along the separated edges, and that above the boom is a similar boom-clamping member 26 held down by a nut 27. These various brackets are spaced at convenient intervals and support the track 28, in the manner illustrated. The track is preferably of the slotted form of a now approved type for feed and litter-carrier use, and it is manifest that by the use of this boom and track in combination, the brackets may be adjusted longitudinally as desired. In addition to the brackets and other attaching means there are provided guy-fastenings, at intervals in accordance with the length of the boom. These consist of lower members 29 and upper members 80, the lower members 29 being like the boom-clamping members which secure the brackets in position, and the upper members being similar thereto but provided with eyes. The two parts of the guy-fastenings are held together by bolts and contribute to the rigidity and strength of the boom. There are also provided trussmembers, each of which has at its center boom-engaging members 31 formed to embrace the boom and to be held together by bolts, as already set forth. Each of the members 31 is provided with a laterallyextending flange in which is a semi-cylindrical groove, the grooves of each two opposing fianges receiving laterally-extending tubes or pipes 32. Each pipe 32 has at its end a vertically-extending cross-bar 3'5 around which is passed a loop 3% threaded at its two ends. A truss-clamp 35 is passed over the two ends of the loop 34 and held in position by nuts on the thread ends of said loop, so as to clamp between itself an the ends of the tubes or pipes 32, a truss rope or wire 36, the inner end of which is secured by a turn-buckle 37 to the ears 22 of the swinging-hinge members of the boom and the outer end of which is secured to bolts 38 at the outer end of the boom. The manner in which these bolts 38 are supported is illustrated in Figs. 10 and 11, where it will be seen that the extreme end bracket has its boom-clamping members 39 and 41-0 extended out-ward to form lateral ears between which the bolts 38 are passed, spread ers being provided around the bolts so as to receive the ends of the truss over the wires.

By the foregoing construction a simple and eflicient device is provided. The boom is exceedingly strong inherently and it is trussed and guyed so as to eliminate any danger of buckling. The track within the barn is connected to the track outside the learn, as illustrated, in accordance with common practice of the present day.

In order to permit the swinging of the boom to occur without unnecessary wear of the guy-ropes, these ropes are secured to a pivoted loop tl which receives its support from a bracket 42 fast on the barn-wall. As the boom is swung the guys on the loop 11 turn therewith so that the guy-ropes do not swing upon any stationary pivot, as has been the case heretofore.

I am aware that considerable variation is possible in the present construction which I have described in detail as the preferred embodiment of my invention. By such detailed description, however, I do not intend to limit myself to the specific form indicated, my intention being on the cont any to claim all the novelty inherent in the construction as broadly as the state of the art will permit.

As one example of the variations in construction which are possible, I have shown in Fig. 15 a modified form of boom which is made of two T-beams, the heads of the T s being placed vertical and adjacent to each other, and the remaining flanges turned outward. This affords a simple construction to which the various mechanisms herein described can readily be applied by modifying the boom-engaging parts after the manner in which the corresponding parts are shown in Fig. 15. Other variations will readily occur to mechanics skilled in the art.

hat I claim as new and desire to secure by Letters Patent, is

1. In combination a track, suspending moans therefor, a pivoted boom supporting the track-supporting means and consisting of two beams spaced apart horizontally and clamping means to hold said beams in fixed relation.

2. In combination a track, suspending means therefor, a pivoted boom consisting of two beams spaced apart horizontally and clamping means to hold the same in fixed relation, the suspending means for the track passing between the two beams and forming part of the clamping means.
