HAT-FORMING MACHINE.

SIECIFIGATION forming part of Letters Patent No. 739,787, dated September 22, 1903. Application filed February 24,1903. Serial No. 144,862. (No model.)

To all whom it may concern;

Be it known that I, JOHN MARSHALL, a citizen of the United States, residing at 110 Chace street, in the city of Fall River, county of 5 Bristol, and Stateof Massachusetts, have invented. a new and useful Improvement in Hat-Forming Machines, of which the following is a specification.

My invention relates more especially to that class of forming machines in which a predetermined quantity of material is automatically weighed out and delivered upon a feeding-apron, which conveys it to the forming-machine for forming into a hat-body.

These weighouts are delivered upon the apron by a proper feeding mechanism in the form of a thin fiat fleece and the process being automatic are delivered regularly, of a uniform width and length, and with uniform 2o intervening spaces.

former-doors is expected to have the doors closed'on the entry of a weigh-out of material to be formed and to open them and re move the formed hat-body while the apron is making no delivery at the intervening spaces between the weigh-outs. This requires great regularity and activity on the part of the attendant. Sometimes the formed bodies are defective and various things occur which de- 0 lay him in getting the doors closed. An entry of the weigh-out while the doors are open results in loss of material, irregular forming, and a general derangement of the regularity and quality of the goods.

The object of my invention is to overcome this liability of entry of the weigh-out while the former-doors are open by making the opening of the doors act as a check upon the oncoming weigh-out as it is advanced by the up apron and releaslng it. as soon as the doors are closed. I attain this object by the mechanism illustrated in the accompanying drawings, in which Figure 1 shows a feed-apron and formingmachine with its doors closed. Fig. 2 shows the same with its doors open.

The attendant at the being ready to receive it.

Similar figures refer to similar parts in both views. 7

1 is an upright stanchion bolted to the former-door 2.

3 is a rocking lever pivoted in a bracket 4, which is bolted to the former-frame 5 at opposite sides of the feedingapron 6. The rocking lever is formed with a curved arm 7,

which terminates in a parallel bar or gate 8,

. crossing the feeding-apron and similarly supported on both sides of it. The curved arm is supplied with an adjustable stop 9, which prevents the gate when lowered from resting on the moving apron and wearing it. The stop is adjusted to just clear the apron, and it also acts as a weight as the rocking lever is operated and the gate depressed by gravity.

10 is a cord orlight chain connecting the fixed stanchion 1 with the rocking lever 3.. 11 11 are the oncoming weigh-outs spread upon the apron.

12 are the feed-rolls between which the materials pass as they enter the former.

The operation is as follows: The intermittent weigh-outs are moving regularly up to the former. In Fig. 1 the doors are shown closed and a weigh-out is just entering between the feed-rolls. In Fig.2 the doors are shown open, the cord 10 is slackened, and the gate 8 has dropped upon the apron and is holding back the next weigh-out and will continue todo so until the former-doors are closed, when it will be released, the former Having thus described my invention, what I'claim, and desire to secure by Letters Patout, is--- 1. In a hatformingmachine, provided with doors the combination therewith of a suspended gate, arranged above the apron feeding the materials to said former, a connection betweensaid gate and said doors,by

which it is raised or lowered as the doors are closed or opened for the purpose set forth, and substantially as described and shown.

2. In a hat-forming machine provided with doors, the combination of a fixed stanchion bolted to one of the doors, a fixed arm adjoining the feeding-apron bolted to the machine-frame, a rocking 'lever pivoted to the fixed arm, formed with a curved arm terminating in a gate-bar crossing said apron, and similarly supported on the opposite side, a stop adjustably bolted to said curved arm,

and a cord or chain connecting the fixed stanchion with the rocking lever and operid ated by said doors, for the purpose set forth,

and substantially as described and shown.
