APPARATUS FOR SEASONING AND RECTIIIFYING PAPER STOCK.

, Application filed December 17, 1927. Serial No. 240,876.

The present invention relates to improvements on the apparatus for seasoning and rectifying paper stock set forth in my Patent No. 1,325,044 dated December 16, 1919.

My improvements relate, first, to means whereby the apparatus may be keptin substantially continuous operation, thus saving time and increasing output; improved panels which can be adjusted so that they may be brought up to the sides of the suspended paper stock and thus insure-the direct upward passage of the air between the sheets and preventing escape of the air laterally, hence resulting in rapid conditioning of the paper; improved means for effecting ventilation, whereby humidity and temperature may be controlled as desired; an improved arrangement of a plurality of fans and groups of heating units whereby the temperature is varied and the humidity lowered according to requirements of the paper stoclgweather conditions, and condition of the temperature in the room; arrangement and relationship of the means for suspending the paper stock, and the portable cabinet carrying the fans, heating units, and panels, whereby only a relatively small amount of floor space is required for the apparatus, the treatment and handling of the stock is facilitated and it is made possible to practically continuously operate the apparatus.

Other objects and improvements over my patent will appear from the following specification of construction and operation, the

novel features and combinations of the apparatus being set forth in the appended claims.

In the accompanying drawings: I

Fig. 7 is a horizontal detail section showing the manner of guiding and mounting the sectional door; and

Fig. Sis a diagram of the electric appliances and wiring.

The cabinet 1 has supporting wheels 2 which travel on flanged rails, enabling the cabinet to be shifted from the fulllinc position of Fig. 1 to the dotted line position thereof and vice versa.

Unlike the cabinet of the apparatus of my Patent No. 1,325,044, it has no top of its own. \Vhen the cabinet 1 is in its respective positions, it is located underneath one or the other of the stationary or permanent tops 4, 5, said top then serving as the top of the cabinet.

The stationary or permanent tops 4, 5, are rigidly suspended from the ceiling (i of the room in which the apparatus is located by rods or hangers 7 and there may be provided 80 suitable braces as shown at'8, if desired. The tops 4, 5, are preferably interbraced by the horizontal angle iron bars 9 secured to the sides of the tops by the bolts 10. The frame work thus provided for the tops 4, 5, holds them in suspended, rigid. horizontal position, spaced or separated from each other, but arranged above the track or rails 3 so that the cabinet may be shifted from beneath one of the tops to the position beneath the other of said tops and when located beneath one of the tops, the open top of the cabinet lies outside of, and closely adjacent to, the depending, braced skirt or apron 11 as best illustrated in Fig. 8, effectually sealing the joint between the side walls of the cabinet 1 and the depend ing side walls of the top 4:, or 5, as the case may be.

Each top is provided with any suitable, or well-known, means for suspending the sheets of paper stock 12 as illustrated in Figs. 2 and In Fig. 2 only a few of the sheets of paper stock 12 are illustrated but it will be understood that the cabinet is well filled with these suspended sheets. I have illustrated a wellknown form of paper suspending clamp at 13, said clamp being adjustably carried by cross bars 14 secured to the tops 4, 5. I

Each of the tops 4, 5, is provided with a ventilator whose purpose will appear hereinafter. This ventilator may assume different forms but, as shown, it Consists of a pair of hinged doors 15, 16 extending practically the entire length of the top and arranged to overlap each other. The res ective doors may be closed, or partially or ully opened by manipulating pull ropes, wires or chains 17, 18 so that either one or both of the doors constituting the ventilator may be set as desired. The ventilator of each top is controllable indcpendcntly of the ventilator of the remaining top. At the front and rear of each top are depending doors or flaps 19, 20 which are in lowered position when the cabinet is closed as shown in Figs. 1, 2, and 4 to overlap the front and rear sectional doors of the cabinet. When, however, it is desired to shift the cabinet from beneath its top, or to arrange the cabinet beneath the remaining top, these doors may be elevated as shown In connection with the top 5, Fig. 1. Any suitable means may be provided for this purpose; I have illustrated a pull chain or rope 21 in each instance so that each fiap may be arranged as desired.

At the ends of the cabinet there are vertically slidable doors comprising two sections 22, 23. The lower part of the cabinet 1s closed by a fixed wall 24. The sections 22,23 are adapted to slide up and down in guides 25 at the corners of the cabinet, as best illustrated in Fig. 7. The guides 25 may be constructed as desired but, as shown, they are of channel form and are composed of angle iron strips connected to the sides of the cabinet, and flat strips with intermediate filler strips connected to the angleiron strips. The door sections 22, 23 have their edges projecting into the guides and one or'both of said door sections is provided with retaining metal strips 26 which straddle the uides 25 and insure a snug fit as between tile door sections and the cabinet.

The section 23 is raised b the section 22, when the latter is elevated, y reason of the co-operating strips at the overlapping edges of said door sections as illustrated in Fig. 6.

This result may be accomplished in different ways but, as shown, the sections 22 and 23 are provided with angle iron strips 27, 28 arranged horizontally and secured to the overlapping edges of said sections. The section 23 has an a 'le iron strip 29 overlying the upper edge of said section and riveted at 30(to the strip 27 and the section 23. The section 22 has a metal strip 31 riveted at 32 to the lower edge of the said section and to the angle iron strip 28.

The aforesaid construction provides engageable members on the sections 22 and 23 by which the section 23 is elevated by, and travels as a unit with, the section 22 when the section 22 is raised sufliciently, whereas when the section 22 is lowered, the section 23 is lowered with it. The sections 22 and 23 can be raised to the full height shown in Figs. 2 and 4, or lowered to lie infront of the fixed section 24, thus enabling the cabinet to be closed at its ends, or opened up thereat.

Hand lifts 33 are provided on section 22 to enable the operative to elevate or lower the sections 22, 23. Latches 34 are adapted to hold the doors in elevated position.

If desired, other means may be used for raising and lowerin the door sections.

The construction shown in Fig. 6 serves the purpose of a relatively tight joint between the sections of the doors so that the air is confined within the cabinet when the paper is under oing seasoning.

for the purpose of counterbalancing the door sections 22, 23, so that they may be easily raised or lowered, counterbalancing ropes or cables, pulleys, and weights are provided, of which cables 35 are connected to the angle iron pieces 28, run over pulleys 36 mounted on the cabinet 1 and are provided with 'counterweights 37 Other cables 38 are connected to the guide straps 26, run over pulleys 39 carrie by the outside of the cabinet 1, and are provided with counterweights 40 located on the "outside' of the cabinet.

The side panels are shown at 41, said panels havmg feet or supports .42 which are pro-- vided with slots receiving the edges of the horizontal flanges 43 at the upper edges of the fixed sections 24. This mounting for the panels 41 enables them to be slid laterally toward or away from each other so that they may be brought snugly up against the edges of the sheets 12 of paper stock, regardless of the width of said sheets. The panels 41,

when thus brgught up against the edges of the sheets 12, necessitate the air currents blown upwardly between the sheets being brought into contact with the surfaces of the sheets because such air currents cannot escape laterally between the sheets. 7 in greater efficiency than is possible with the hinged anels set forth in my Patent 1,325,044 where t e inclined position of the panels permits a part of the air to divert laterally .before it has risen to the full height of the sheets of paper.

With the present panels, this greater eflicienc is obtained regardless of the width of the sieets 12.

Between the panels 41 and the sides of the cabinet 1 are spaces or diving fines 44 down.

traverse the sheets, thus keeping up the cyclewhich is set forth and claimed in my Patent 1,325,044.

To eliminate dead aim pockets and to facil- This results I itate the travel-of the air currents, the tops 4. 5 are of more or less dome shape, being pro vided with arched corners 45. The lower part of the cabinet is provided with batlle plates 46 or formed in general deflecting shape so that the air currents descending the diving flues 44 to the bottom of the cabinet will be deflected upwardly.

In the bottom of the cabinet 1 is a ventilator, preferably similar to the ventilator 15, 16, comprising the hinged doors 47, 48 which overla and are adapted to be opened upwardly. ny suitable means, not shown, may be provided for setting these ventilator sections 47, 48 many desired position, either fully closed. fully opened, or in intermediate position and each of them may be operated independently of the other one.

In my Patent 1,325,044 I have proposed the use of a single electric fan combined with a plurality of electric heaters located in the lower part of the cabinet and used to heat the air and blow it upwardly between the sheets of paper stock.

As a part of the present improvements, I provide a plurality of electric fans located above the electric heaters and use electric heaters which are arranged in groups, each group having its own controlling switch, as shown in the diagram, Fig. 8. The number of heaters in each group and the total number employed, as also the number of electric fans,

will vary according to the size of the installation. The provision of a. plurality of heating units arranged in different controllable groups, in connection with a plurality of fans, enables different air temperatures to be attained, according to the number of groups of heaters which are utilized. Thus, it is within the control of the operative to meet the existing conditions as to temperature and humidity so that the most rapid and thorough seasoning and rectifying effects may be obtained.

The electric fans appear at 49. Beneath the fans are the electric heating units 50 comprising insulated'bars of resistant material arranged in groups bridged on the main circuit 57 and the branches 52, 53. 54 for the respective switches 55, 56, 57. The main circuit appears at 58 and supplies the current direct to the fans 49. The main control switch appears at and the electric supply circuit at 60.

'hen the switch 59 is closed, all of the fans 49 are set in operation but as many of the heating units 50 may be employed as found desirable. the others being cut out through the control at the switches 55, 56, 57.

The apparatus is adapted to carry out the process set forth in my Patent No."1,325,044 and is used in the following manner.

Assuming that the cabinet 1 is in the position shown by dotted lines, Fig. 1, the sheets 12 of paper stock which are to be seasoned against the edges of the paper stock 12. Thedoors 22, 23 are then raised and latched. 'lhe fans 49 are set in operation by closing the switch 59 and, according to requirements, as many of the electrical heating units 50 are switched on by the use of any or all of the switches 55, 56, 57 as may be necessary. The air is blown upwardly between the sheets 12 and then dives down the tines 44, carrying out the process set forth in my Patent 1,325,044. The air diving down the fines 44 is re-heated and forced upwardly by the fans 49, the cycle continuing as long as necessary to effect the desired results.

As soon as the cabinet is closed when in the full line position of Fig. 1, and the fans and heaters set in operation, the operative may immediately begin to suspend paper from the clamps provided in the cover 5 so that the cover 5 may be fully loaded while the paper suspended from the cover 4 is belng conditioned. Thus, the operative loses no time waiting for the paper to be seasoned and by the use of the two covers 4, 5, arranged adj acent each other, the operation of the apparatus may be kept substantially continuous.

\Vhen the paper suspended from the cover 4 and enclosed in the cabinet 1 has been properly conditioned, the flaps or upper doors 19, 20 of the cover 4 may be raised and the sectional doors 22, 23 at both ends of the cabinet lowered, whereupon the cabinet 1 may be rolled from the position shown in full lines in Fig. 1 to the position shown in dotted lines in Fig. 1, the flap doors 19, 20 of the cover 5 having been raised to enable the cabinet to be located beneath cover 5. The sectional doors 22, 23 may then be raised and i the flap doors 19, 20 of the cover 5 lowered to completely enclose the suspended paper stool; carried by the cover 5, the panels 41 havlng been previously adjusted to bring them up against the edges of the suspended paper.

The operative then sets the fans and heaters in operation, when the closed cabinet is in position to treat the paper suspended by the cover 5, and directs his attention to the seasoned and rectified paper stock remaining suspended from the coveix4. This stock having been removed, fresh unconditioned, paper stock is suspended from the clamps carried by the cover 4. Thus, by the provision of two fixed covers, 4, 5, relatively arranged so that the cabinet can be moved to position it under either one of them, I do away entirely with the removable cover set forth in my patent and greatly increase the capaeity of the apparatus.

The efliciency of the apparatus is increased by reason of the employment of the adjustable panels 41 and the quick-acting doors as also the employment of a plurality oi fans and groups of heating units, more or less of which may be used according to requirements. Furthermore, the ol'tput of the apparatus during a given period is greatly increased. If the ventilators 15, 16 and 47, 48 are kept closed while the pa er is being conditioned, the percentage of umidit is lowered while the heaters are in use. Ift ese ventilators are opened, the temperature of the paper may be reduced, bringing it down to the same temperature as existing in the room.

The use of a plurality of fans affords an even distribution of the air circulation which quiclzens the process of bringing the paper stock into equilibrium with the temperature and humidity existing in the room, provided no heat is used. If heat be used, the humidity content of the paper stock may be lowered to any desired extent and constitutes a practical means for reducing the temperature in such amanner that the paper stock does not attract back to itself the humidity existing in the room when it is removed from the machine.-

Thus, the user can employ heat or dispense with it, as conditions may warrant.

As previously explained, the adjustable panels 41 prevent the air currents from spreading laterally and cause them to travel upwardly past the entire surfaces of the sheets.
