Applicatipnflled September 18, 1813. ScriaLIqm 796,404 1'- f' i To all whom. it may. concern Be it known, that I, BneirnennlA. PABKEQ of Philadelphia, in the county i Philadelphia-and State of Pennsylvania, have in- 5 vented: certain new and useful. Improvements in FebrieDrying Machines, whereof the following is a specification, reference being had to-the accompanying drawings.

This invention relates to fabric drying machines of that type in: which the fabric to be dried is hung; in looped form from. an

endless conveyor passing through the drying apparatus," as isshownnnd described in my co-pending application filed April. th, 15 1913,. Serial No. 761,244. In this type of apparatus it is desired to obtain the greatest capacity of. looped-fabric within the drying chamber as possible, andin the use of the apparatiis ofmy' copehding: application,

50. ithas been fonndfthat the web often partielly falls over. the next pole of the conveyer before the loop being formed is. com pleted, thus shortening the length. of the loopbeing-for-med and consequently correspondingly diminishing the capacity of. the

apparatus. Funthermore, at times, too much of the web is fed between, apair of poles, and consequently a longer; loop is formed which drags on the bottom of theappanatus and becomes soiledr -One object of this invention. is, therefore,

to provide means for forming the loops in uniform lengths: and thereby insure a full capacity.

Another object oftheinvention is to provide means 'for preventing. the Web. falling oven the next adjacent. pole until;- the loop being formed is completed;

A further object of; the invention is to 40 provide means for positivel i feeding the web between adjacent poles, and consequently preventing any: possibility of the web falling over the ,nextsncceeding pole T harness 16015 oftliepioper-length."'

The web is fed in advance of the roll '16, and in rear of the roll 17, and these rolls are driven in unison by'intermeshing gears 18, and 19,

upper roll is dispensed with, and a guide respectively mounted on said rolls. The upper roll 16, is provided -with a pulley 20, which is driven by a belt 21, from a pulley 22, mounted on the shaft 23, of the feed roll 10, the shaft 23, being timed with the conveyer to properly feed the web to the latter. The guide and feed rolls 16, and 17, are positioned relative to the clamping roll 12, to feed the proper amount of Web between each pair of poles 7, so that it is impossible for the web to drop upon the next adjacent pole until the loop being formed is completed.

-At the same time, by reason of the rolls 16,

and '17, being positively driven and timed with the conveyer, theproper lengths of fabric will be successively fed to each pair V of poles 'i, of the conveyer. It will be observed that the initial starting of anew loop is not begun until the clamping roll has clampedthe web of the loop last. formed to the last or adjacent pole 7. The clamping rollthus prevents the last loop, which has been previously formed of proper size, from being varied by the formation of a new loop.

In Figs. I and II, I have shown two erolls 16, and 17, for accomplishing the object of my invention, but I do not wish to be liinited to this constructiomas other means such as are shown in Figs. III to VII, inclusive may be employed if desired, and without departing "from the-spirit ofjmy invention. In the construction shown in Fig. III, the

board 24:, is substituted therefor, said board being. suitably supported by the casing, 5. This board guides the web. between each pair of poles 7, and the roll 17, positively feeds said web. V v

. In-Fig. IV,'the' bracket '14:, supports a pivoted and weighted clamping member 25, whose function is identical with thatjo-f the clamping roll 12. In'this figure Ihave; provided the guide board 24:, shown in Fig. EIV.

but have substituted for the feed roll 17, 'of' said figure, an endless eonveyer 26, forgthe web which positively feeds said web between each pair of poles 7, of the main conveyer;

Fig. V, shows the stop or clamping roll 12, and combined feed .and guide rolls 30, and 31, arranged one above the other and engaging one side only of the web.

In the. structure shownin Fig. VI, th feed rolls 10, and 11, are intermittentlyectuated by any suitable means not shown, and the auxiliary feed roll 17, is correspondingly actuated through the belt drive. Associated with this form is the guide board 24, and the web is fed between this board and the roll 17. Each pole 7 is provided with teeth 35, for engaging the web. In operation, when the space between a given pair of poles is in proper position, the

feed rolls 10, 11, and 17, are actuated, thus feeding the proper amount of the web between said poles. The teeth 35, ineffect, perform the same function as the clamping roll 12, previously described, the teeth pressing into the Web as the latter passes under the guide board and thereby retain the completed loop against becoming shortened or lengthened.

The structure embodiedfirrxEig.;.VII, is similar to that shown in Fig. VI, except the feed roll 17, and guide board are removed, and opposed endless conveyers 36,- 36, are substituted and are disposed on the opposite sides of the Web. 7.

From the foregoing 's'will be seen that I have provided means for successively'fonm ing loops of uniform size and that means are provided for preventing the initial starting of the next adjacent loop until the loop being formed is completed, thus causing the machine to always operate in full capacity.

WhileI have described my invention as especially adapted for use in connection with an apparatus for drying fabrics, it will be understood that my improved feeding details of construction and the arrangement of parts may be made without departing from the spirit of the invention, as set forth in the appended claims.

Having thus described my invention, I claim:

A drying apparatus comprising a con tinuouslv traveling endless conveyer, spaced su 'iporting poles fixed to said conveyer from which loops of fabric are to be sus pended, a device for clamping the web against a pole for starting a new loop of fabric, and means. for positively feeding hope of fabric between the poles at a point the poles at a. point close to, said clamping 10 ad acent said clamping devi device.
