SPECIFICATION forming pari; of Letters Patent No. 686,557, dated November 12, 1901.

Application filed February 18, 1901. Serial No. 47,738. (No model.)

The object of this invention is to provide avery simple and efficient tackle-block--a block which may be made largely by stamping out of sheet metal and will be at once very cheap to produce and very strong and durable.

The invention consists in the arrangement and construction of parts which contribute to the above end. It includes the utilization of a supporting-strap to lock the axle in place, broadly, and alsomore specifically, as shown; and it includes other features which contribute to the general result, all of which will be described, and definitely setout in the claims. The drawings clearly disclose my invention. The views on Sheet 1 show various embodiments of my tackle-block assembled. Figure 1 is a side elevation, Fig. 2 an edge elevation, and Fig. 3 a central section, of the tackle- -block having two sheaves, which is the most common form. Fig. 4. is a central section of it with one sheave, and Fig. 5 a central section with three sheaves. Fig. 6 is a fragmentary section of the axle, showing lthe interlocking strap. The remaining views, which are on Sheet 2, show separately all the parts necessary to compose the double tackle-block shown in Figs. 1, 2, and 3. On this latter sheet Fig. 7 represents the frame, Figs. 8 and 9 the separators, Fig. 10 the main supporting-strap, and Fig. 11 the locking-strap, Fig. 12 the axle, Fig. 13 the retaining-bolt and nut, Figs. 14 and 15 the sheaves, and Fig. 16 the becket. One of the purposes of this sheet of drawings is to clearly illustrate the large proportion of the tackle-block which may be stamped of sheet metal.

Referring to the parts by letters, A represents the frame, which is composed of the two outside plates a oand the bridge-plate a2, connecting the two plates at the top. At its lower end the side plates o' a have the inwardly-projecting lips a3 a3. The side plates are dished oroffset outward, as at a4, to provide for the reception of the supporting-strap and to stiften these'side plates. Through these portions a4 is a hole a5 to receive the ends of the axle. The construction of the side plates of the frame is substantially the same whatever the number of sheaves used. The bridge-plate a2 has different openings in it, according to the requirements, as will be explained. The axle (indicated by B) occupies, as stated, the openings a5 and loosely supports one or more sheaves C. The strain is taken directly from the sheaves and axle to the main supporting-strap D, which is of the general U shape and has through its legs d the openings d', which surround the "axle, the strap occupying the space provided by lthe oiiiset a5 of the frame and passing through openings a@ in the bridge.

The construction so far described is substan tially the same in each form ofthe tackleblock.

Where two sheaves are used, I provide a pair of separators F., as shown detached in Figs. 8 and 9, which have openings e, through which the axle may take, which have at their edges strengthening-tiangese and at their upper edges lips e2 and lat their lower edges flanges or projections e3. The lips are adapted to take into Openings, as a7, in the bridgeplate a2 ofthe frame, and the projections e3 are adapted to abut against the side plates o a just within the lips a3. When but two sheaves are' used, the two separating-plates E E are back to back and have their [langes e abutting, as shown in Fig. 2.

When three sheaves are used, as shown in Fig. 5, there is placed between the two separators E a third separator F, the sides of which are formed just like the sides of the separators E, but are connected together at their base by thecross-plate f, whereby a U shape is given to the intermediate separator. If four or more of the sheaves were used, the number of these intermediate separators would be simply increased. The lips ezf at the upper ends of the separators take into openings in the bridge-plate a2, and the separators are held in place thereby and by the axle and by the bolt G, which extends through holes Yas in the side plates and through the holes e4 in the separators and has on its end a riveted head or nut g. Now between the abutting plates E o r the plate E and the plate F, as the case may be, there is a space provided, owing to the flanges on these plates, and this space is occupied by a second strap II. This strap has the two ends h h connected at the upper end by the loop h and having through the two legs the openings 7b2. In the form shown in Figs. 2, 3, and ll these legs are in contact with each other. In the form illustrated in Fig. 5 they are separated, but parallel with each other. In either event the two legs lie in the space between the separators. Now the holes h2 in this strap H are of the right size to allow the passage of the axle B; but in use theyT are out of alinement longitudinally with the holes in the separatorsthat is to say, the distance between the holes h2 and the holes h3, through which the bolt G passes, is greater than the distance between the holes e and the holes e4 or the holes 0.5 and the holes as. When the parts are assembled, the axle is passed through the wheels, separators, and straps before the bolt G is in place, wherefore the holes h2 may be caused to aline with the others. Thereafter the strap II is drawn upward to bring the hole h3 into alinement with the holes e4 a3, and this brings the lower edge of the holes h2 into one or more notches b, formed in the lower side of the axle, and at the same timebrin gs the strap l-I up against the strap D at the upper end, the holes being so positioned that this will take place. When the strap H is brought up against the strap D, the axle is not only locked in place, but it bears on the lower surface of the hole h2 as well as on the holes in the straps D, wherefore each of these straps helps carry the axle, and through it the weight, upon the wheels. Vith the parts in this position the holes h3 aline with the holes e4 and a8, and the bolt G is put in place and locked and there held, whereby the whole tackle-block is locked together.

When but one sheave is used, the strapsD and H are consolidated into one strap, (indicated byJ in Fig. 4.) The holesj, near the lower end of this strap, allow the passage of the axle B and then by elevation take into the notches b therein, the strap being held in this locked position by the bolt G passing through the frame A and the strap and held by a nut or rivet g. This bolt serves the purpose of the bolt G in the former cases in holding the strap so that its holes are out of alinement with the circumference of the axle. At the lower end the frame A is properly held by the bolt G2, passing through the distance-tube G3 and locked by the nut or rivet g2.

A becket L is provided for the attachment of the end of the rope. This becket takes through an opening e5 in one of the separatorlugs and loops around the bolt G.

In assembling the parts the separators are first placed within the frame, the straps putin place with their openings alined, the sheaves put between the separators, and the axle shoved home. The axle is then turned, if necessary, as by a screw-driver in the slot b in its end, to bring the notch or notches b onto the lower side, and the locking-strap is drawn up to lock the axle, whereupon the lockingbolt is shoved home and securely held.

Having described my invention, I claim-- l.
