,To all whom it may concern.-

Be it known that I, KARL WESSEL, a subject of the German Emperor, residing at Lan sing, in the county of Cook and State ot Illinois, have invented certain new and useful Improvements in Hay-Curlin g Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a novel construction in hay curling machines and has for its object to provide a device of this character, of simple and durable construction and which will curl or crimp the hay in an effectual manner.

The invention consists in the features of construction and combinations of parts hereinafter fully described and specifically claimed.

In the accompanying drawings illustrating my invention,-Figure 1 is an end elevation of the same. Fig. 2 isa vertical cross section. Fig. 3 is a vertical longitudinal section. Fig. i is a fragmentary detail view.

Referring now to said drawings, A and B indicate the end frames or standards of the machine which are suitably connected and braced together by two beams 1. About midway between the upper and lower ends of the standards A and B are located the journal bearings or boxes 2 that are adapted to receive the hollow journals 3 and i upon the end of a cylinder 5. These hollow journals 3 and 4 communicate with the interior of said cylinder 5 and serve to permit the ingress and egress of steam. The said journals 3 and a extend beyond the bearings 2, and the journal 3 is provided thereat with a drive pulley 6` or the means for'rotating the same. A steamsupply pipe 7 communicates with the end of the hollow journal 3, and a stuffing box 8 serves to form a tight connection between said pipe 7 and journal 3. In this way it will be seen steam can be admitted to the said hollow journal and to the interior of the cylinder 5.` It will, of course, be understood that I can employ a different medium for cylinder, but I have found steam convenient and preferable. The journal i at the other end of the cylinder communicates at its outer end with an outlet pipe 9 and is provided with a stuffing box 10 to form a tight joint therewith, in an obvious manner. The construction of said cylinder 5 is as follows: Two hollow disks 11 that are connected and communicate with thejournals 3 and 4 serve to form the ends of said cylinder, and said disks are connected with each other by a hollow cylindrical casing l2 joined at its ends to said disks as shown in Fig. 3. A series of openings or perforations 13 are made in 4the periphery of each of said disks so that the perforations in eachv disk are in alignment with each other. A series of pipes 14 are provided with inwardly bent ends 15 and these ends are inserted within the openings or perforations 13 in the hollow disks, and secured in such a manner as to make a steam tight joint therewith. In this way it will be seen that the pipes 14 will stand away from the face of the cylinder, but parallel therewith, as shown in Figs. 2 and 3, and that the entire face of the cylinder will be provided with the laterally projecting pipes 14. The said pipes 11i are supported so that they will stand at all times parallel with the face of the cylinder by bars 16 that extend between said pipes and the face of the cylinder and from one end of the cylinder to the other, so that said pipes will be braced along their entire length, as will be manifest. Located between each of said lines of pipes and extending the whole length ofthe same is a 'series' of grooved or transversely curved gutters 17. These gutters 17 are secured along their side edges to the pipes 11i and serve to produce in eect a corrugated cylinder or a cylinder having a series of grooves and intervening ribs or ridges.

To the top of the standards A and B, and concentric with the journals of the cylinder, are arranged a plurality of journal bearings or boxes 18. The said boxes or bearings 18 are located within guides 19 that are readily arranged with relation to the cylinder, and the said boxes 18 have a sliding connection with said guides and are controlled by two screws or bolts 2O and 21 arranged respectively above and below said boxes 18 and bearing against the same, so that by suitably turning said screws or bolts the bearings 18 IOO can be nicely adjusted. Said boxes 1S at 'each end of the machine are arranged in alignment with each other and receive the journals 22 and 23 on the ends of the pressure rollers 24. A plurality of these pressure rollers 24 are employed, as shownfin Figs. 1 and 2, and they are disposed about the cylinder as shown. Each of said pressure rollers 24 is constructed as follows: Connected and communicating with the hollow journals 22 and 23 are the hollow disks 25 and 26 which are "connected with each other by a pipe or tube 27, and said pipe or tube 27 is smaller than the disks 25 and 26, so that said disks project beyond the same. Uponl the inner faces of said disks 25 and 26 a series of perj forations or openings are made which receive the ends of pipes 28, as clearly shown in Fig. 3. The said pipes 28 are located parallel with the face of the tube 27 and are supported in this position by bars 29 that extend the entire length of said tube 27. Located between each of the pipes 28 is a transversely grooved or curved cutter 30 which is secured along its edges to the pipes 28, as clearly shown in Fig. 4. The said pressure rollers 24 are so disposed with relation to the cylinder 5 that the grooves and ridges on saidpressure rollers will intermesh or interiit with the grooves and ridges on the cylinder, so that as said cylinder is turned it will in turn rotate said pressure rollers upon their journals. The devices for introducing steam or other heating medium into said pressure rollers are constructed as follows: The said hollow jour nals 22 and 23 extend beyond their bearing boxes and the journal 22 communicates with an inlet pipe 31 for supplying steam thereto. A stuihng box 32 serves to form a tight joint between the inlet pipe 3l and the said journal. Each of said inlet pipes is connected by a radial pipe 34 to astufting box a on the curved pipe b, to allow longitudinal movement of said pipes 34 when it is desired to adjust the small pressure rollers 24. The other hollow journal 23 of the pressure rollers con1- municates with an outlet pipe 35, and a stufting box 36 is employed to make a tight connection between these parts. The said outlet pipes 35 are similarly connected by radial pipes 34 to stuing boxes aon a curved pipe b for the same reasons. In this way it will be seen that hot steam is admitted through the hollow journal 22 and disk 25 to the pipes 28 of the pressure rollers, so as to heat the same, while at the same time steam is admitted to the pipes 14 of the cylinder to impart heat to these pipes.

As shown in Fig. 1 a shelf or table 37 is secured between the standards A and B of the machine just below the first of the series of pressure rollers and formsat-able or platform upon which the hay can rest while being fed into the machine. Just below the last of the series of pressure rollers, and on the other side of the machine, is arranged a delivering roll 38 which is preferably ribbed, as shown,

and upon which the hay will fall and be de-1 flected outwardly, in an obvious manner.

TWhen the hay is to ybe curled it is fed across the table 37 in a moist and dampened condition, while at the same time the pipes of the cylinder and pressure rollers are heated by the passing of steam therethrough and the cylinder is rotated. As the hay is fed between the I'irst of the series of pressure rollers and the cylinder it will be caught between thesame and moved or fed along so as to pass between each pressure roller and the cylinder. The hot pipes serve to dry the moisture out of the hay, and by reason of the intertting pipes and the corrugated form of the cylinder the hay will also be curled or crimped and pressed into the desired condition and will emerge in this condition from the last pressure roller.

It will, of course, be 'understood that the gutters or curved pieces between the pipes 17 and 28 serve to prevent the hay from entering behind these pipes and clogging the ma-y chine, and it will also be noted that in ac'- cordance with the principle involved by my invention I contemplate omitting such gutters it' it is found desirable, whereupon the supporting bars 16 and 29 which support the pipes 14 and 28 will serve to prevent the hay from clogging behind the said pipes.
