HAY-CARRIER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 526,839, dated october 2,1894.

Y Application filed May 22,1893. sentano. 475,301. (Numan.)

To l2f/ZZ whom t may concern.-

Be it known that I, WILLIAM LOUDEN, a citizen of the United States, residing at Fairfield, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement in HayCarrier Apparatus, of which the following is a specification. L

This invention relates to hay carrier apparatus; and consists in means for making the necessary attachments to the head of said rail, so as to economize room and let the carrier pass freely by them; also, in an improved form of suspending hook, andinother details hereinafter set forth.

In the accompanying drawings representing the invention Figure l. is a perspective showing the rail with the attachments secured to it and having a hay carrier andA its tackle block mounted thereon. Fig. 2. is a cross section drawn on the lin-e cc, y, of Fig. l.

Fig. 3. is a cross section drawn on the line z, of Fig. l. Figs. 4 and 5 are modified forms of the end stop.

A` represents the rail, and B the carrier7 which latter may be of any desired construction adapted to run upon the side flanges of the rail, and having a longitudinal opening through the center Lof the upper part of its frame to clear the attachments mounted upon the upper edge of the rail.

C is the splice clamp which unites the ad.

joining sections of the rail, and D is the trip;

stop which operates the lock mechanism of the carrier. f

E and E represent the suspending hooks and F the rafter brackets by which they are.

supported. It will be observed that these attachments are all made in two parts, which are clamped to the upper edge or head hof the rail A by means of bolts G. Plainly shown in Figs. 2 and 3. These dual clamping pieces are made dishing or so as to set to one side of the central line of the rail, where the bolt G passes through them. This feature is shown in Figs. l, 2, and 3,-particularly in Fig. 3, in which the dotted line Q. Q. represents the central line of the rail A.

It is desirable to have the carrier wheels w run upon the side anges of the rail atas nearly equal distances from the central line Q, Q, as practical, so that the weight of the carrier load may bear equally upon both `sides of the rail, that the rail may be held perfectly in line with the upper end of the suspending hooks IE. As ordinary bolts are made the burrs b are always considerably `thicker than the heads a, and vwhen two parallel vplates of equal thickness are bolted t0- gether the point e of the bolt will always stand/farther out from the common center than the head. To give the threads of the bolt a good hold, the point of the bolt should project through the burr b, and in case the head h of the railA should be of small size this would make the points e project through the burrs still more. Naturally the point of the bolt would come closer to the carrier wheels W than the head a, and from its shape would be much. Inore liable to catch on the carrier wheels or frame than the head, even if they were both the same distance away. This requires a`wide opening through the carrier to escape the points of the bolts, and wide flanges on the sides ofthe rail for the carrier wheels to run on, while there will be room to spare on the side having the heads of the bolts. I overcome thisdifficulty and reduce the space re' 'quired 4to the vminimum by dishing the parts of the attachment used to clamp the head of the rai1, so as to set the head a of the bolt out from, and the point e in toward the center line Q, Q. By vthis means the point e will be set in toward the center line and shielded from contact withthe carrier, and

the head a being rounded the carrier will readily slip around it in case of contact. This feature is applicable alike to the suspending clamps E and E', splice clamps C, trip stop D, or any other attachment composed of two pieces and'designed toibe clamped upon the khead of the rail byrmeans of a bolt G in the least possible spaceV to avoid contact with the passing carrier. I

The splice clamp C is composed of the two pieces C and C2 formed and bolted together on the head of the railv A as alreadydescri'bed. The central parts of these pieces are extended downward to embrace ythev central web of vthe rail as shown in the drawings, and the piece C has two pins Cs formed upon its lower section. Holes corresponding to these pins are made in the adjoining ends of therails and also in the part C2 of the clamp. When the pieces C and C? are bolted together these pins O5 will enter ICO the holes in the rail, and also in the part C2, and eiectually hold the ends of the rails together without depending altogether upon the clamping power of the bolts.

The suspending deviceE is composed of the main part L having a hook H at its upper end to catch over the rafter bracket F, and a llange H at its lower end to catch under the head ot' the rail and the clamping part H2 which is also preferably fitted with a flange H3 to catch under the head of the rail. These two parts, L and H2, are held together by the bolt G, and will firmly grip the head of the rail between them. 'lo h'old the pieces comprising the hanger from slipping on each other, a flange or shoulder H4 is formed on the main part L, which liange catches under a shoulder or olfset H5 on the clamping part H2, all of which is clearly shown in Fig. 2. The nut b of the bolt G is set in a recess While the main part of the han ger is strengthened by a flange I'I6 at one or both sides of the nut. This forms a very simple, strong, easily applied hanging device for a hay carrier track rail, and may be tted with any suitable suspending means at its upper end. However, I prefer to use a hook H to catch over the rafter bracket F and to pivot a latch or linger M to the point ot' the hook to close the throat, of the hook and prevent it from getting oft the bracket.

The latch or nger M is preferably pivoted at one end in a slot or opening in the point of the hook, while its opposite end enters an opening in the shank of'the hook, and is held in place by a key K. However, this order may be reversed. and the latch be pivoted in the shank of the hook and secured by the key to the point of the hook as shown in the hanger E in Fig. l, in which the latch is shown open to admit or release the bracket F.

To secure the tackle of the carrier to the rail A, I form a hook I in two parts, J and J, fitted with jaws J2 and J3 to grasp the side flanges of the rail, and a bolt G3 to hold the two parts firmly upon the rail. The pulley P through which the carrier rope passes is hung in this hook, which may also be provided with a latch M similar to that used in the suspending hook E. This hook may be clamped upon the side flanges of the rail at any point on the track and be held by the clamping power of the bolt Gi8 alone, or it may be set at the end of the rail as shown in Fig. l, and a nail or pin be passed through holes N in the jaws .I2 and J3, and made to rest against the end of the rail A and prevent the hook the carrier tackle.

To prevent the carrier from running off the track, and also to keep it from running against and injuring the pulley RI place a stop S upon the lower edge of the rail A, so as to project on either side sufficiently to abut the frame of the carrier and positively arrestits movement along the track. This stop is made of wood or any other material which will not injure the frame of the carrier. It is shown in its simplest form in Fig. 5, in which I use a block of woodhaving two holes, and a U shaped bolt T, passing around the top of the rail and through the holes, so as to clamp the stop to the rail. The holes are made near the back edge of the stop so the carrier wheels will not run against thebolt T. In Fig. l, my preferred form of clamp for the stop is shown, comprising two clamping pieces R, hinged together above the rail, each piece provided with a shoulder r to grasp the head of the rail between them. rlhey are bolted to the stop as shown in the drawings. rlhis form of clamp takes a very firm grip on the rail and holds the stop so it cannot be bumped loose by the carrier. Vhen the stop S is used in connection with the hook I, they should be placed far enough apart so the carrier will strike .the stop before striking the pulley P.

Fig. 4 shows a modified form of stop S having a notch o designed to be used in connection with a rail A having a lower head h2. The clamping pieces R can also be used with this form of stop.
