To all whom t may concern:

Be it known that I, ROY T. AXE, a citizenv of theUnited States, and a resident-.of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Spring-Roller, of which the following is a specification. l

VThis invention relates to springl rollers for raising or counterbalancing curtains, Windows, etc., which is particularly simple and economical in construction andhighly eiiicient and durable in use and it consists in the combinations and Constructions hereinafter set forth and claimed.

In describing this invention, reference is hadto the accompanying drawings in.` -which like charactersl designate corresponding parts in all the views.

Figure l isa longitudinal sectional view, partly broken away, of a roller embodying my invention. A

Figs.V 2 and 3 are sectional-views taken ,vrespectively on lines 2 2, and 3-3, Fig. l.

lV designates the body of the roller, which is here shown as tubular throughout.

2 and 3 are, respectively, the heads vatopposite ends Yof the body, in which are supported theaxles 4, 5, one of which as the axle 4 rotates with the roller andthe other of which as 5 is held from rotation, so that the body of the roller-revolvesaround'said axle.

6 is the spring connected at one end to the body of the roller asghereinafter described, and at its other end to a portion of the axle `5, the spring tending to rotate the body of the roller aroundthe axle y5.

Each head y2,3 consists of two -discoidal members, one of which is-formed-.with a cylindrical flange which lits into oneend of the tubular body 1, and the other of which lies contiguous tothe former member with its outer margin lapping the.,end edge of the tubular vbody 1. Each head Yis also formed withan opening for the axle 4.-or 5 of the roller.

7 and 8 designate themembers of the head 2, ,the member 7 having a cylindrical Yflange 9 which Vlits into the end of the-tubular body l, and 4the member 8v beinga fiat; disk,r the outer margin of which lapsat 10 the end of the tubular body 1. The member 7 is held in position by suitable fastening members as screws l1 extending through the wall of the body land into the cylindrical flange y9. Both members 7, 8 are formed with suitable central openingsfor the axle 4. Said axle 4 consists of a rod'extending throughthe central openings of the members 7, 8 of the head 2 and supported at its inner end by-a member12 litting the tubular body 1 opposed to and spaced apart from the head 2. A sleevev 13 is inserted between the disk 12 and the discoidal member 7, said sleeve abutting at its ends against the said parts 7 and 12 and being located in alinement with the central openings thereof. The axle 4 is provided with a flange or shoulder 14 abutting against the outer ends iof the member 8 of the head2andwith a shoulder l5 at its inner end'abutting against the inner face of the disk 12.

Preferably, the central portion of the disk 12 is projected toform a. spherical boss as shown at 16.

17 and 18 designate the parts of the head in which the. axle 5 -is located, the member 17 being similar in construction to the member 7 of the head 2 butv having its central opening of larger diameter than the part of the axle 5 therein. The member` 18 is similar to the member 8 of the head 2 but isl provided with a hub 19 which extends into the central opening of the memberv 17 and which has its inner end spread in the form of a flange at 20 in order to form a peripheral circumferential groove in which-the margin ofthe member 17 around its central opening is held.

The outerA margin of the member 18 laps the end edge of the tubular body at 21.

The peripheries of both

members

8 and 18 are substantially flush with thel periphery of the body l of the roller.

The axle 5 is provided with an annular shoulder 22 which abuts the outer face of the member 18, and said axle includes arstub portion located within the tubular body /1 anda tubularportion'23 mounted onthe stublportion and` securedthereto by akey 24 purpose of the disk 27 is to receive in one of the holes 29, a locking pin inserted through the

holes

30, 31 for the purpose of holding the spring 6 under tension: whent'he roller is dismounted.

The tubular portion 23 of the axle 5 is supported at its inner end by a bearing or lug member 32 which includes a cup-shaped ody having a tubular hub 33 projecting from its bottom 34C and in which the part 23 of the axle 5 is journaled. Said plug member also includes a plate or disk 35 inserted in the cup-shaped' member vagainst the bottom 34, the disk being held in position by shoulders 36 on the cylindrical wall of the cup-shaped part. Said shoulders are formed by indenting the cylindrical wall at intervals so that the indented portions overlie the margin of the disk 35. The member. 32 is held in position by a key 37 extending transversely through the body 1 of the roller Vand through lengthwise slots 38 formed in the lmember 32 and opening through the edge of the cup-shaped part so that said member 32 can be removed and replaced upon axial-movement thereof.

The spring 6 is connectedat one end to the axle 5 or the tubular portion 23 thereof and at its other end to the member 32, it being here shown as having its extreme end portion 39 passed through a loop 40 provided on the member 32. v
