'HOOP-FORMING. MACHINE.

Application tiled October 25,1915.

compact in construction thereby occupying" a minimum of space, to simplify the construction and reduce the number of working parts, to permit of the several parts being easily gotten at for inspection, or in case of- 4renewal, and generally to adapt the several parts to better perform the functions required of them, and it consists essentially of the improved machine particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawingsz' Figure 1 is a side elevation of the improved hoop machine. Fig. 2 is an end elevation of the same. Fig. 3 is an enlarged detail of the means for adjusting the bending wheels and the belt carried thereby. Fig. 4; is a transverse section on the line 2-2 of Fig. 3.

Like characters of reference refer to like parts in the several drawings.

Referring to the drawings, A represents.

the improved machine comprising the frame 10 provided at one end with a longitudinally extending slot 11 designed to house the lower offset arm of the L-shaped bracket 12. It is desirable that this bracket shouldbe capable of horizontal adjustment, and to this end the set screw 13 is threaded in the frame and rotatably engaged at the end to the bracket 12'to ,which it is secured by the collar 14 or in any other suitable mane ner.

The bracket 12 is provided with a longitudinally extending slot 15 in the lower arm designed to slidably carry the bearing 16 therein, which is adapted to be moved in a horizontal direction under the action of the set screw 17 threaded in the said bracket and contacting at its point with one end of the spiral spring 18, the other end of which engages a recess 19 in the said bearing. The

Specification of Letters Patent.

Serial No. 57,735.

vertical arm of the bracket 12 is also provided with a slot 20 adapted to slidably carry the bearing 21 adapted to be vertically adjusted by the set screw 22, making threaded engagement with the upper end of the said bracket, and coacting at its lower end with the spring 23 which in turn engages the upper end of the bearing.

`In the embodiment illustrated, the bearing 16 carries a stub spindle 2li: provided intermediate of its length with a collar 25 designed to engage with the inner face of the bearing and provided with a threaded outer end with which the nut 26 engages to rigidly secure the spindle in position. The overhanging end of the spindle 24: carries a flanged corrugated bending wheel 27 rotatably mounted thereon adapted to cooperate with the pressure roller 28 rotatably carried by the bearing 21 and located between the flanges of the bending wheel.

That end of the frame 10 remote from the bracket 12 carries a shaft 29 rotatably mounted therein provided on one end with a flanged corrugated bending wheel 30 and on the other end with a pinion wheel 31 designed to mesh with the pinion wheel 32 mounted on the spindle 33 rotatably carried by the frame, the said spindle having a belt pulley 34 mounted on its outer end adapted to be driven from any suitable source of power.

(lo-acting with the under side of the bending wheel 30 is a pressure roller 35 rotatably supported in the bearing 36, adjustably mounted in the bracket 37 formed integral with thel frame and capable of being moved in a vertical directionby the set screw 38` making threaded engagement with the said bracket and engaging one end of the spiral spring 39, the other end of which engages the bearing.

The

bending wheels

27 and 30 are connected by a belt l0 of steel or like resilient material passing therearound, which ene gages on its outer face with` the pressure rollers 28 and 35.

In the operation of the machine, rotary motion is transmitted to the pulley 34 which through the coacting gearing 32 and 31 rotates the bending wheel 30 and drives the belt 40, and the corrugated rollers 28 and are then adjusted until they exert the desired pressure on the said belt. The strips of wood or metal previously cut to the desired lengths are fed between the belt 40 and the

bending wheels

27 and 30 and so formed. It will be appreciated that it is only neces- .sary to engage the point of the strip of wood or metal between the belt 40 and its coacting bending wheel and since the bending wheels are flanged the said strips cannot get out of alinement with the belt. These strips are fed alternately to one end of the machine and then to the other and this operation is performed by a single attendant. As the bent strips travel along the belt 40 they contact with the discharge plate l1 carried by the frame 10 and located between the inner faces of the belt, and are thereby thrown laterally from the machine.

It will be clear that should the belt 40 require tensioning, this can be accomplished by adjusting either of the set screws 13 or 17, the former controlling the L-shaped bracket 12 and the latter the movement of the bearing 16.

Should it be so found desirable to exert a greater pressure between the belt 40 and the

bending wheels

27 and 30, the rollers 28 and 35 are adjusted by their respective set screws to obtain the desired result.

The function of the flanges on the

bending wheels

27 and 30 is to prevent displacement of the belt Ll0, and strips of wood being bent which are subjected to an even pressure-so that the hoops bent are uniform.

Since different sizes of hoops will be bent in one machine, the bending wheels are capable of being replaced by wheels of larger or smaller diameter.

l/Vhat I claim as my invention is:

l. In a machine of the class described and in combination, a frame, flanged bending wheels mounted on the opposite ends thereof, a belt passing around and operatively connecting the said wheels,d means for moving one of the wheels longitudinally of the frame to adjust the tension of the belt, means for rotating the other wheel, and a discharge plate mounted on the frame and located between the inner faces of the belt.

2. In a machine of the class described and in combination, a frame having a slot in one end thereof, an L-shaped bracket provided with a lower odset arm slidably engaging the said slot, a bending wheel rotatably supported by the lower arm of the said bracket, a second bending wheel mounted on the opposite end of the frame, a belt passing around and operatively connecting the bending wheels, means for rotating the second bending wheel, and means for moving the L-shaped bracket longitudinally of the frame to adjust the tension of the belt.

3. In a machine of the class described and in combination, flanged bending wheels mounted on the opposite ends thereof, a belt passing around and operatively connecting the said wheels, an adjustable pressure roller located between the flanges of each of the wheels to engage the belt, the rollers being arranged on diametrically opposite sides of the wheels, means for vertically adjusting the pressure rollers, means for moving one of the bending wheels longitudinally of the frame to adjust the tension of the belt, and means for rotating the other bending wheel.

4. In a machine of the class described and in combination, a frame, an L-shaped bracket slidably mounted therein provided with a longitudinally extending slot in the lower arm, a bearing slidably mounted in the said slot, a bending wheel rotatably supported by the bearing, a second bending wheel rotatably supported at the opposite end of the frame, a belt passing around and operatively connecting the bending wheels, j j

means for rotating the second bending wheel and means for moving the bearing in a longitudinal direction to adjust the tension of the belt.

5. In a machine of the class described and in combination, a frame, an L-shaped bracket slidably mounted therein provided with a vertically disposed slot in its vertical arm, a bearing slidably mounted in the slot, a bending wheel carried by the L-shaped bracket, a bending wheel rotatably mounted on the opposite end of the machine, a belt passing around the bending wheels, a pressure roller carried by the said bearing, a set screw making threaded engagement with the upper end of the L-shaped bracket, a spiral spring located between the set screw and the bearing and means for rotating the bending wheels.

G. In a machine of the class described and in combination, a frame, corrugated bending wheels mounted on the opposite ends of the frame, a belt taking around the said wheels, means for adjusting the tension of the belt and pressure rollers coperating with the pending wheels, as and for the purpose speci- In witness whereof I have hereunto set my hand in the presence of two witnesses.
