. BERTRAND A. PARKES, OF PHILADELPHIA, PENNSYLVANIA.
DRYING-MACHINE.
To all whom it may concern: 1
Be it known that I, BERTRAND A. Burns, a citizen of the United: States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Drying-Machine, of which the fol lowing is a specification.
My invention relates to the class of devices employed for the drying of stockings, gloves, and other washable articles, which are adapted to be stretched or placed upon forms in their dyed and wet condition, and after having been subjected to heat and a current of air while upon the forms, to be removed therefrom .and replaced by others to be similarly treated.
The principal object of my invention is the provision of an apparatus of the foregoing character in which the articles to be dried, after having been placed upon the forms, are automatically fed into the machine, dried within it and automatically delivered from it.
A further-object of my invention is the organization of an apparatus in which the articles to be dried will becaused to travel close to heated steam of heat, and will be su jected to currents of hot air, steam or kindred heating medium, circulated through the apparatus and against said articles, conveniently by means of a. fan which operates in connection with an exhaust outlet and-"serves not only to drive the hot air against the articles to be dried, re-circulate it and also to force out the moist air. I
A further object of my invention is to so organize my apparatus that it will have a capacity for drying a large number of articles without its taking up a great deal of floor space and.without involving unnecessarily complex mechanism.
lVith the foregoing and other objects in view, my invention comprehends a machine in which a plurality of articlecarrying forms may be introduced successive within a casing inclosing, or being a part of, a drying chamber, and after having made a traverse of such chamber are successively automatically taken out therefrom.
My invention further comprehends specific means associated with the drying chamber for effecting the passage and circulation of hot air through it and the escape of moist air out of it; and, finally, comprehends Specification of Letters Patent.
ipes or other sources,
specific devices in cooperative assemblage for carrying out the objects I have mentioned, typical embodiments of which are represented in the accompanying drawings and hereinafter described, the particular subject matter which I claim as novel being definitel recited in the claims. 5
For t e purpose of illustrating my invention I have shown in the accompanying drawings a certain type 'andembodiment of it wherein the forms are those intended for the drying of stockings, which is at present preferred by me because in practice it willbe found to give satisfactory and reliable results.
It is to be understood, however, that the various instrumentalities in which my invention is represented as embodied can be variously arranged and organized and that w Fig; 3 represents a top plan view of said machine; 7
Fig. 4 represents a transverse, sectional elevation on the line 44& of Fig. 3, of the right-hand or distant-end of the machine; Fig. 5 represents a fragmentary detached view, partly sectional and partly elevational, of a part of one of the form-carrying disks, the rockin ratchet-operating devices which occasion the intermittent rotation of said disk, and apart of one of the article-carrying forms hinged to said disk, and its adjuncts; i

Fig. 9 represents a detached cross-sectional View on the line 9--9 of Fig. 8, through a spindle and its carrying tube;
Similar numerals of reference indicate corresponding parts. 4
Before describing the specific devices which are preferably utilized in the construction and operation of my drying apparatus, it is in point to explain that the general organization of the machine embraces a casing 1, of any preferred construction, the side members of which T designate 2 and 3, the end members a and 5, the base 6, and the cover which is partly longitudinally curved or segmental and designated 7, and partly flat or table-like longitudinally along the edges of the curved portion and designated 8 and 9. The inclosing plates of the side and end members are for clearer illustration of the inclosed parts, omitted.
Within this casing as an entirety, is contained both an interior drying chamber 10,
and longitudinally extending side compartments 11 and 12, within which are contained any system of, for instance, steam pipes'13 and 14, to supply the heat or other drying medium.
The drying chamber 10 is located beneath, and inclosed above by, the curved portion 7 of the cover, and extends longitudinally of the casing and preferably to the left hand side of the center as illustrated in Figs. 1, 2 and 3, while the side compartments 11 and 12 are at opposite sides of and parallel tothe drying chamber.
The machine illustrated is a double machine in which a double set or dual plurality of article-carrying forms 15 are oppositely disposed at each end, so that two operators, one at each end of the machine, can operate simultaneously upon the opposite sets of forms, and,-therefore, do twice the amount of Work that could be done in the machine if it were organized as a single machine to be operated from one end only, by one operator, and with but one set of forms.
The fact that T have illustrated and herein described a double machine in no Wise affects the essential working members of it'when organized as a single machine, be cause, as shown, said members are simply counterparts of each other, and, as in a single assemblage of similar elements, are caused to operate simultaneously by similar but duplicated means. a
In the organization illustrated, there are at each end compartments 16-17 in which are contained the devices which occasion the movement of" the forms to raise themout of the drying chamber of the machine so that the article to be dried can be placed upon them, then to lower them into the drying chamber, so that the articles upon them as may be dried, then to move them through the :neraeea drying chamber, and then, finally, to lift them out of it.
As a general explanation it may he said that the article-carrying forms 15 are fiat or oval, and preferably possess the outline o the article to be slipped over them 5 dried,-ll have illustrated forms for s ings,-and that these forms are hinged their lower ends.
Within the compartments 16 and 17, these forms are assembled, mounted in desired pluralities upon their carrying disks,--a plurality at each end of the machine, and each form is adapted to be turned flatwisc when it is out of the machine so as to be more easily supplied with the article-to be dried, and is further adapted then to he turned edgewise and in such position to be tilted downward and entered through a form-slot in the curved cover of the macc chine, into the drying chamber.
Within said chamber each form is adapted to be carried around lying edgewise and nesting against its neighbors, and then, after having been so carried around within said dryingchamber and its article dried, is adapted to be tilted upward and lifted out of said chamber through another form-slot and is then turned to be stripped of the article which has been upon it and been dried,
r and then supplied with another article to be dried,after which the operation is repeated.
My machine, therefore, comprehends means for successively lifting the forms out of the drying chamber while each is in an edgewise position,-for, while out of the chamber, turning them into a flat'wise position to make it easy to slip the article upon them,and for then again turning theminto edgewise position so that they can be dropped into the chamber.
Further than this, my machine comprehends means for eflecting the rotary movement of the pluralities of forms all lying 1w edgewise next to each other within the drying chamber, and, in addition, means for supplying heat to the drying chamber, all as hereinafter explained.
Referring first to a good means of heating the drying chamber, T find it convenient to employ a rotary fan 18 contained within the larger, 12, of the two heating compartments which I have designated 11 and 12, and which compartment, in effect, is in part a fan chamber and in part a steam chamber.
The operation of this fan is, conveniently, by means of a fan shaft 19 upon which it is mounted and which is housed in bearings 2021 in the frame-work and driven by a band 22 passing over a driven band wheel 23 on said shaft and leading from a driving band wheel 24:.
The fan causes a circulation and recirculation of the heat through and around the drying chamber 10 in the general direction of the arrows in Fig. 3,an inlet 65, see Fig. 2, within which the fan is mounted, being the ingoing aperture for the heat to within the dr ing chamber, and apertures 80 and 81, see --ig. 3, being the outlets therefrom.
109 is an outlet for moisture from within the casing. a
25 designates a driving pulley on the chain shaft 19, by which the machine is actuated, and 26 is a shaft upon which the driving band wheel 24 is mounted.
This shaft 26is mounted in a bearing 27 fast to the frame-work, see Fig. 3, and at-its 'inner end has fastened to it a small beveled pinion 28 in mesh with a larger beveled pinion 29 fast upon a gear shaft 30, see Figs. 2 and 4, mounted longitudinally of the frame-worki'in bearings 31, 32.
The beveled pinion 29 is formed with a hub extension 33 which terminates in a clutch face 34, and both pinion 29 and clutch face 34 are rotatable or loose upon the gear shaft 30, and adapted to be. put into operation by the engagement of a sliding clutch face 35 held against rotation but permitted to slide edgewis'e upon the gear shaft by a key 36.
This sliding clutch face 35 is adapted to be moved longitudinally on the gear shaft 30 by a clutch yoke 37 the forked depending ends of which are entered within a circular channel 38 formed in thehub of the sliding clutch face, and'the yoke itself is affixed to and depends from a shifter rod 39 extending the length of the machine and passing through slide bearings 4041 in the end frames of the machine from either of which it is operated, by being pushed in or out to stop or start the machine.
42 designates the main shaft of the ma;
chine, extending longitudinallv and below,
and concentrically, so to speak, with, the
curved cover 7 of the casing, and being housed in 'bearings-4344 inthe framework .of the machine.
The form-carrying disks and their operation. Upon the ends of the main shaft 42 are mounted the form-carrying disks 45, to which the article-carrying forms 15 are hinged or pivoted, and upon the outer face of each of which is formed or secured a circular side-plate ratchet 46.
In this connection I should explain that while I prefer to employ disks in the proper sense, that is fiat, circular plates, I do not limit myself thereto, because, obviously, ring-like, spoked or skeleton constructions provided with ratchet teeth, are the mechanical equivalents in the assemblage of wo'i'king elements of disks proper.
With this reservation I- hereinafter use the word disk.
the entire periphery of a form-carrying disk 'blage of hinged brackets 47 suflicient to fill is employed, and the number will, of course,
depend upon the number of forms which it is desired to use.
The means by which the form-carrying disks are synchronously rotated in a step by step advance movement, are the following 49 designates a sprocket chain mounted on a, sprocket wheel '50 on the gear shaft 30,
and extending over a chain-tightening sprocket 51, inwardly, or transversely of the machine, and over a pair of sprocket wheels 52.53, of which 52 is provided with a sideface cam 54 which, in the rotat'ion'of said sprocket wheel 52, encounters a cam roller 55, Figs. 1, 4 and 5, and through such encounter is adapted to deflect or rock upon a stud 56 fixed to a housing 63, a rocking frame 57 which carries, as best seen in Fig.
'5, a ratchet .pin 58 slidable within a socket v 59 being a. part ofthe rocking frame, and
held to duty against the teeth of the circular ratchet 46 on the form-carrying disk 45, by a spring 60 which holds it out as shown.
The two sprocket wheels 52 and 53 are respectively mounted in stud bearings 61' and 1 62in a housing 63 at the end of, anderected from, the base "of the machine,.being the same housing or end plate (in duplicate, of
course) in which are mounted the bearings 43 and 44 of the main shaft and the stud 56 for the rocking frame 57 of the cam roller 55. 64 designates a return spring connected with the rocking frame 57. and also with the frame-work of the machine, the object of which is to hold the cam roller 55 to duty against the cam 54 and so to insure the re,- te-ntion, of the ratchet pin 58 against the ratchet teeth.
Itwill be obvious that in the movement of the sprocket chain 49, through the encounter of the cam 54 on the sprocket wheel 52, the cam roller 55 will occasion a predetermined swing of the rocking frame 5?, and that said swing will be accompanied by such swinging of the ratchet pin 58 as will occasion by its contact with a given ratchet tooth of ratchet plate 46, a partial and 'pre-- determined rotation of the form-carrying disk operate-d upon. v v As there are counterpart and similarly operated sprocket chains upon each end of the machine each similarly operating with a form-carrying disk, it will be evident that by the means described both of such disks will be simultaneously rotated step by step to an extent of rotary peripheral movement governed by the dimensions and proportionate circumferential placing of the ratchet teeth.
Having now described a preferred means by which rotary movement is imparted to the form-carrying disks, to the end that the desired rotary or circumferential movement may be given to the forms both when without and when within the drying chamber. 10,
I will first describe a good construction of the forms themselves and then describe an effective means for first holding and then turning said forms first edgewise and then fiatwise, to an angle of 45, while they are outside of the heating chamber and casing, and so as to present them flatwise for the operator to place the article to be dried upon them, and then edgewise for tilting into and through the form-slot through which they pass into, through and out of the drying chamber.
T he article-ca-r-ra ing forms.
Referring now to Figs. 7, 8 and 9, in which a portion of a form-carrying disk 45 is represented, and also a few of the hinge brackets 47 attached to said disk and to which the article-carrying forms are pivoted or hinged,the form proper, 15, itself, is preferably mounted upon a form-head 66, being, conveniently, a plate to which the form is attached by screws 67.
At one of its ends the form-head is so shaped as to extend downwardly as a socket 68 for a spindle 69, which enters and is rotatable within a spindle-carrying tube 70, the lower portion of which is pivotally or hingedly connected by a hinge pin 71, with a hinge bracket 47, and which tube, below said bracket, extends farther downward and angularly outward to form a hook heel 72, the upturned book of which is designated 7 3.
In order to permit of a quarter turn of the article-carrying form, the spindle 69 is rotatable within its carrying tube 70, to a 45 turn, by forming said tube 70 with a 45 slot 74 through which extends a range pin 75 screwed to the spindle, as illustrated in Fig. 9.
The return of the article-carrying form, when turned, to an angle of 45, under the limitation of movement of the range pin, is effected by a coiled return spring 76 on the spindle, fastened at one end, as at 77, to the spindle-carrying tube 70, and at the other end fastened, as at 78, to a collar 79 looked upon the spindle 69, as illustrated in Fig. 8.
Assuming the normal position of the form 15 to be that illustrated in Fig. 7 and in full lines in Fig. 8, it will be understood that said form can be turned to a rightangle, or 45 from the full lines to the dotted lines, and reversely, and it may be further mentioned that this turn is at the proper time accomplished by form cams 101 and 105 on the curved cover 7 of the casing, as hereinafter described.
It will be further understood that the article-carrying form as an entirety is susceptible of being tilted upon its hinge from the vertical position represented in full lines in Fi s. 7 and 8 to the horizontal )osition represented in dotted lines in Fig. 8, and that this tilting is conveniently accomplished through the following means operating upon the hook-heel 72.
The form tilting mechanism and its operation.
Mounted in sockets 82 and 83, or otherwise fixedly secured to the-housing 63, are radially disposed guide rods 84 and 85 upon which respectively travel slides 86 and 87.
The slide 86 through a hook 88 pivoted to it controls the lift or upward tilting of an article-carrying form upon its hinge pin 71, by the engagement of said hook 88 with the hook 73 of the hook-heel 72, see Fig. 8, and said hook 88 is normally held in a relatively vertical end engaging position by a spring 89, see Figs. 1 and 8.
The improper movement of the hook 88,
is preferably limited by a stop 90 as shown in Fig. 1.
From the foregoing it will be understood how a given article-carrying form is tilted from its horizontal position or that shown in dotted lines in Fig. 8 to its vertical position, or that shown in Figs. 7 and 8.
The end for end, or an in and out, movement of the slide 86 upon its guide rod 84 is conveniently effected by a connecting rod 91, best seen in Fig. 4, at its lower end connected with the sprocket wheel 53 by a crank pin 92, and at its upper end connected with said slide 86 by a connecting pin 93.
Obviously, in the rotary movement of the sprocket wheel 53 already explained the slide 86 will be moved upwardly and downwardly on its guide rod 84.
' The movement of the slide 87 on its guide rod 85,which is the movment that tilts an article-carrying form from its vertical to its horizontal position,--is similarly accomplished by a connecting rod 94 which extends from a crank pin 95 on the sprocket wheel 52 to a connecting pin 96 on the slide 87, and by providing said'slide with a latin full lines in Fig. 8 to that represented in dotted lines in said figure. i
The gearing up of the two sprocket wheels 52 and 53, and their common chain 49, and also the placing of the two crank pins .92 and 93, is such as to determine the desired movement of the slides 86 and 87 the one after the other in constant but varying thrust upon their respective connecting The ofiice of these two guiding devices is to assume the maintenance of the articlecarrying forms in their horizontal position, during their traverse through the drying chamber.
Having now' described the means for effecting the tilting of the forms from without to within the drying chamber, and re versely, it remains to explain how they are operated both externally of and within said drying chamber.
Assuming given forms 15, which I have also, in the position they are shown as occupying in Fig. 1, designated 1, 2, and 3, it will be noticed that number 1 is edgewise and numbers 2 and 3 flatwise of the end of.
the machine.
Number 1 occupying the edgewise position which it has been occupying in its travel within and through the drying cham ber, is assumed to have in'such position been lifted through a form-slot 98, see Figs. 1 and 3, extending longitudinally through the curved cover 7 of the casing, into registry or alinement with which slot its form-carrying disk 45, which is rotating in the direc tion of the arrow on it, see Fig. 1, has brought .it,and that it has been lifted through said slot 98 by the action of the hook 88 on the slide 86 at the time when the rotation of its form-carrying disk has been stopped at a step, so-called, occasioned by the regulated movement of the ratchet on said disk.
Assume, further, that in the rotary movement of the form-carrying disk in its next step by step advance, an ensuing turn of the form Wlll be given it so as to adapt-it to enter and travel flatwise in the crossslot 99 which connects the slot 98 with a second longitudinal slot 100 in the casing which parallels said slot 98, it is obvious that in said cross-slot 99 said form will occupy the flatwise position represented by form members 2 and 3, in Fig. 1, so that the operator can take off the article dried and put on an article to be dried.
This turn of the form under consideration from its edgewise to its flatwise position is occasioned by the encounter of the form-head 66 of the form 15 with a cam 101 on the curved cover 7, which effects the turn in opposition to the operation of the return spring 76 on the spindle 69 of said form 15, and it is obvious that when the form in its flatwise position has traversed the cross-slot 99, it will after having had the dried stocking or other article removed from it and a new one put on it be again turned so as to present itself edgewise and in alinement with the slot 100 into which slot by the then upward action of the slide 87 it will be tilted into the drying chamber of the machine.
As the machine described is double, a corresponding operation will take place with the counterpart forms of the formcarrying disk at the right-hand end of the machine, as shown in Figs. 3 and 4, and the turning and lifting and dropping of said forms will be similarly effected in connection with an oppositely disposed pair of parallel slots 102,104, and a connecting or cross-slot 103 upon the curved cover 7, to the right ofthe slots 98 99 and 100 shown upon the left of said cover, in said figures, and with a cam 105, preferably having a s irin 'extension 106 and which 0 erates in connection with said second series of slots and with the right-hand form-carrying disk in a similar way to effect a similar turning of the set of counterpart forms.
Having described in connection with their construction the operation of the several devices which in their assemblage constitute an embodiment of my inventioinit will be unnecessary further to describe the operation of the machine as awh0le,and i will be apparent that my machine as illustrated and described embodies the features of advantage which I have enumerated as desirable to accomplish the objects which I have stated that I have had in View.
It will be understood, moreover, that various changes in the form, proportions, dimensions and minor details of the apparatus as an entirety, may be made without departing from the spirit of my invention or sacrificing any of its advantages.
Although, further, I have described and illustrated my invention in considerable detail, it is to be understood that-it is not limited to such details further than is indicated in the appended claims, and thls because, in its broader aspects, the invention may be embodied in various other forms.
