Letters .Patent No. 101,854, cla-ted .April 12, 187 0.

Thesohedule referred to in these Letters Patent and making part of the same.

ll, OLVER S. GAlumTsoN, of the city of Buffalo,`

mg.- In this case theparts of the pulley cannot be fastened together till the device is fitted in the sash,

which occasions considerable inconvenience and waste of time in handling and putting up the pulleys.

Another method is to secure the parts together by two rivets, and a third by eyelets fitting inlthe holes for the screws which secure the pulley to the casing; the latter mode being described in a patent heretofiu'e granted to me.

My improvement' relates to a method of securing the cap to the face-plate, whereby only one rivetfor the purpose is required.

The in'veution consists of a small lip projection cast with the face-plate, and arranged so as to overlap the edges of 'a'. base fiange at one end ofthe cap arranged thereunder, while the opposite end of the cap is fastened hy a rivet, as will be hereinafter fully dcscri bed.

In. lthe accompanying drawings- Figure I is a vertical section of my improved pulley.

Y Figure II is a plan of the cap, detached.

Figure III a'plan of the'pulley complete.

Like lettersvdesignate 'like parts in each of the figures. v

A is the face-plate cast with standards or side-portions, a, in which are, formed the bearings of the wheel B.

C is the cap having the sides contiguous to thc faceplate, recessed as shown, and cast with auges, c, at each cud of the base, which fit against the face-plate. These flanges-are formed with notches, c c2, having preferably beveled edges, as shown.

eis the lip cast with the face-plate, audso coustructed and arranged as to fit in the notch c, and overlap the edges thereof, whereby the cap at this end is secured against the face-plate, the not-ch preventing lateral displacement. y

The opposite end of the cap is secured by a rivet, i, fitting in notch c2, as clearly represented in Figs. I and III.

Although I prefer to employ the notch c* to prevent lateial displacement of the cap, it is evident that the same result maybe accomplished by casting the face-plate with the seat Nfor the cap depressed, or

by casting one or more indentations therein, to correspond with a tooth or spur cast on the contiguous base of the cap, or by means of a bead or other stop -projectiug from the face-plate at the sides of the cap.

The upper edges of the side portions a ci' the faceplate may be made-to conform to the recess in the sides of thc-cap, or be made so as to leave openings s s, between the contiguous edges, as shownin Fig. I.

Where the cap is attached by means of two rivets, the ilanges c are required to be made of sucient width to enable thel rivet-holes to be formed therein. This construction requires the face-plate to be made correspondingly longer, involving the use of more metal than would otherwise be needed, and producing a less compact article.

By the use of my improvement I avoid these objections and the extra labor of riveting, and am enabled to cast-.and put up the pulleys at a less cost; a slightsaving in the manufacture of this and other light castings, which have to be sold at a low price,

being a matter of importa ce.

'What I claim as my invention is The arrangement of the lip c and rivet c with the flanges c c, so that a cap cast in.oue piece may be secured by a single rivet to the face-plate thereolsui.

stantially as hereinbefore set forth.

OLIVER 'S. GARRETSON.
