and guide rollers 15, 16 and 17 disposed at the I The main objects of this invention are:

First, to provide a drier for printed sheets which is of large capacity and at the same time Compact and simple in structure.

Second, to provide a drier of the class described which may be readily coupled or associated with a printing machine and which is automatic in operation. i

Objects pertaining to details and economies of construction and operation of my invention will definitely appear from the description to follow. The invention is defined in the claims.

A structure embodying the features of my inventionis clearly illustrated in the accompanying drawings, in which:

Fig. 1 is a fragmentary side elevation of my improved drying machine or apparatus, a fragment only ofthe printing machlne being illustrated.

Fig. 2 is a fragmentary plan view partially in section on line'2+2 of Fig. 1.

Fig. 3is a perspective view of one of the conveyor links with its carrier.

Fig. 4 is a fragmentary section of the conveyor.

. Fig. 5 is a side elevation of the apparatus provided with a housing for certain parts.

In the accompanying drawings 1 represents a fragment of a printingmachine and 2 a moving part thereof. My Improveddrying apparatus comprises a frame consisting of the upright members 3,4 and 5 suitably braced and connected to support the moving parts, and the horizontal bed members 6 which are mounted on the upright members 3 and 4.

On the bed members 6. I mount a feed way consisting of the members 7,8 and 9 arranged in spaced pairs to receivetheplunger .10

which is reciprocatingly mounted on the way 11. On these uprights I mount opposed way members 12 and 13 preferably of angle iron and disposed in opposed spaced pairs, the

pairs of way members being downwardly inclined. The horizontally disposed way members 14 extend between the lower ends of the way members 12 and 13. v

These way members are arranged in a triangular relation with conveyor supporting angles thereof. The rollerl'Z is the driving roller of the conveyor,its shaft 18 havinga ratchet wheel 19 at one end thereof. This ratchet-wheel .is driven through the pawl 20 carried by the rocker 21 oscillatingly mounted on the shaft 18 at the inside of the ratchet wheeL, This rocker is connected to the arm 22 on the roc-kshaft 23 by means of the link 24.

The rockshaft is operatively connected to the moving member 2 of the printing machine through the lever 25 pivoted at 26 and connectedto the member 2 by the link 27 and to the arm 28 on the rockshaft 23 by'the link 29. The rockshaft 23 has an arm 30with a' segmental slot 31 therein toreceive the bolt 32 on the adjustable arm This adjustable arm is connected by thelink 34 to thelever 35 pivoted at36 and connected by the link 37 to the plunger. Thus the plunger is driven in synchronism with the conveyor which has' a step by step movement, owing to its. ratchet drivin'g'means. The link 34also hasan ad justable' connection to the lever 35 as indi- I cated so that. the stroke of the plunger may be considerably varied. I I o The conveyor chain is made upof a' plurality of links 38 having spaced rigidarms 39. to which the carrier fingers 40 are secured. Thesefingers are formed of wire and are of considerable spread so as to eftective'lyhold sheets of considerable size. By the term sheets I contemplate cards andthe like.

the sheets are delivered by the plunger they are pushed through the guide members 8 and thereby centered relative to the carriers, a sheet being indicatedbydotted lines at 41, Fig.2. The feed way'isarranged in a plane-radial to the toothed roller 17 so that the sheets are effectively delivered to be picked up by the carrier fingers or flights which pass through openings 42 in the feed I he sheets are carried upbythe forward reach-of; the conveyor, passing over the roller 15 at which' point they are shifted from one flight to the preceding flight, then carried 1 down the rear reach of the conveyorand discharged to the guide chute 43, whichis ar- 1 is sufficiently dry so they.v arenotlikely to oftset. V a

i I have illustrated my improvementsin an embodiment which'I have found very satis-' factory; I have not attempted to illustrate ordescribeother modifications or adaptations which I contemplate as I believe this disclosure willenablethoseskilled in the art to embody or adapt the same as may bedesired.

Having thus described my invention what li clairn as new and desire to secure by Letters Patent is: 1'. Inan apparatus of the class described,
