BENJAMIN LEVI, OF NEW YORK, N. Y.

WASHING AND DRYING MACHINE.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed April 24, 1913. Serial No. 763,289.

To all whom it may concern Be it known that I, BENJAMIN LEVI, a citizen of the United States, and a resident of New York, county and State of New York, have invented new and useful Improvements in Washing and Drying Machines, of which the'following is a specification.

The main features of this machine for Washing and drying sheet material consist of a section of a continuous paper carrier consisting of a conveyer upon which the washing is done and which is composed of narrow belts substantially horizontally arranged, with their edges contiguous, thus forming an unbroken surface for the material, generally paper, which when wet is apt to sag and catch between the adjacent edges of the narrow belts forming such conveyers as are now in use; and an incline section of the belt conveyer which receives the material from the washing section of the conveyer; an open face heater for directing heated air to the material on the inclined section of the conveyer; a heated drum which receives the material from the inclined section of the conveyer; a holding belt or apron partly surrounding the drum; and an air blast producing device, as a fan, for directing the leading end of the material from the inclined section of the conveyer to the entrance between the drum and its apron. These parts with other detail features of construction will be fully understood by reference had to the accompanying drawings, in which:

Figure 1 is a verticallongitudinal section of a machine embodying the essential features of this invention, the frame holding the various parts being omitted. Fig. 2 is anenlarged plan view of a portion of the machine, with the preliminary heater and the drum apron removed, and Fig. 3' is a vertical transverse section on line 3, 3, Fig. 1,

showing a portion of the Washing belt bed 'guider rollers.

The washing section of the belt conveyer is composed of narrow belts a and 6 arranged with their edges close together or in contact, said belts being carried by rollers c, d, and 6;

all of the belts pass around the roller 0, and r the alternate sets of belts a and 6 pass around the rollers (11 and 6 respectively. Conveniently arranged to act on the underruns of this belt conveyer are two sets of guide rollers f and g of the same width as the narrow belts a and b and they are carried on the shafts i1. and 71 respectively, arranged so that the rollers of one set will extend in the spaces of the other set, said spaces ofcourse being equal to the widths of the narrow belts, thus providing perfect guides for said belts, insuring their proper action on the carrying rollers to constitute a traveling washing bed of continuous surface, without gaps between the belts ofwhich it is composed. As shown the upper guide rollers f press one set of belts, as belts or, downwardly the other set of alternate belts b passing through the spaces between the rollers f.

A tank y' located beneath the conveyer a, 6,. contains the washing fluid or water, which by a suitable pump 70 is through the pipe Z carried to the sprinkling device m, composed of the requisite number of perforated pipes arranged above the conveyor to thoroughly spray all parts of the sheet material placed thereon. Beneath the conveyer is a trough n arranged to direct all drippings back to the tank j. For the final washing of the sheet material a fresh water sprinkler 0 is provided, the water from which also, after acting on the material passes to the tank j. The washing fluid'by continual use would become saturated with the chemicals washed from the sheet material, when such is chemically. prepared,

but the addition of the fresh washing water terial as it is carried upwardly on the inclined section of the belt conveyer from the horizontal washing section of the conveyer. The heater r is provided with a wire netting front 25 to prevent any paper material being treated from entering the heater and sobeing a source of danger if gas flames, as shown, be used for heating purposes.

The upwardly extending conveyer section 8 is composed of two sets of narrow belts. One set comprising alternate belts pass over the roller 6 and the other set of intervening belts pass over the roller u. The rollers (Z, 6, u are provided with gears and are caused to run in unison by the intermediate gear wheels 2;, one of which may be provided with a driving pulley 'w. The roller 6 is common to one set of belts of each of the section a- Z) and s of the conveyer. This organization is such that there is a continuity in the operative connection of the various devices, which individually show novelty over the citations and which collectively perform special functions in a novel manner. This method of operating the sections of belt conveyers is described and claimed in United States Letters Patent Number 1,052,007, issued to me February 4, 1913.

The upper end of the section 8 of the conveyer is carried on a roller 0: in close proximity to a drying drum 3 the heat of which may be supplied by a gas burner 2 extending in the interior of the drum through a hollow bearing.

Extending partly around the drying drum y is a belt or apron 1 which passes around the roller 2 located beneath the drum and over guide rollers 3, 3, one of which is close to the drum near the roller :0 of the conveyer s, and a portion of this apron is in front of the conveyer s and extends down close to the heater 7, so heat arising therefrom will be directed toward the conveyer s. The roller 2 and drum 3 are connected by gear wheels, and this roller is also connected to the driving pulley w by suitable gearing, as sprocket wheels and a chain 4:, the arrangement being such that the peripheral speed of the drum will slightly exceed that of the section 8 of the belt conveyer.

The paper or other material is delivered from the section 8 to the drum, and when in the formof sheets there is sometimes a liability for the leading edge of a sheet to adhere to the conveyer section instead of passing to the bite of'the drum and the apron. To guard against this a gentle blast of air is caused to play toward the roller :0 being guided by a plate 5 adjacent to the conveyer and a curved plate 6; this plate 6 also acts to discharge the material from the drum. This air blast may be produced by any suitable means, as a small electrically driven fan 7.

vent the paper,"particularly when in the form of a long strip, moving any great distance away from the carrier, thus insuring the proper conveyance of the paper when such tendency of the paper to leave the carrier exists. The part or section a, Z), of the paper carrier provides a horizontal table upon which the material may be conveniently fed and the inclined section or conveyer s properly presents the material to the drying drum.

It has been found that in treating some kinds of paper fine creases or markings due to washing will show when it leaves the drying drum, and all such marks may be eliminated by a spring actuated roller 9 pressing on the apron to produce an ironing effect on the material as it passes between the apron and drum beneath said roller.

I claim:

1. A machine of the character described, comprising a heated drum, an endless apron partly surrounding the drum, means for grinding and controlling the apron, an inclined paper conveyer with itsdischarge end adjacent the drum near the entrance between the drum and apron, a guide plate extending downwardly at the rear side of the paper conveyer for directing the paper away from the drum at the point where the apron leaves the drum, and means for pro ducing an air blast upwardly between the paper carrier and the guide plate.

2. A machine of the character described, comprising a heated drum, an endless apron partly surrounding the drum, means for guiding and controlling the apron, an inclined paper conveyer with its discharge end adjacent the drum near the entrance between the drum and apron, said apron being arranged to extend over the front run of the paper conveyer, whereby the paper is directed to the entrance between the apron and drum.

3. A machine of the character described, comprising a heated drum, an endless apron partly surrounding the drum, means for grinding and controlling the apron, an inclined paper conveyer with its discharge end adjacent the drum near the entrance between the drum and apron, said apron being arranged to extend over the upper portion of the front run of the paper conveyer, and a heater located in front of the lower part of the paper conveyer below the apron. 4. A machine of the character described, comprising a heated drum, an endless apron partly surrounding the drum, means for guiding and controlling the apron, a paper conveyer with its discharge end adjacent the drum near the entrance between the drum and apron, a heater located in front of the paper conveyer to preliminarily dry paper subscribed my name this 21st day of April, 0 carried therein, and a spraying pipe idiEPt- 1913. ed to spray t e paper on the conveyer e ore it passes in front of the heater and having BENJAMIN LEVI 5 a portion located in the heater to heat the In the presence of spraying fluid. WVM J. DoLAN In testimony whereof I have hereunto JAMES A. HUDSON.
