' Specification of Letters Patent. 7

Patented July 28, 1908 Application filed August 23,1906. Serial No. 331,720.

. I will enable others skilled in the art to which it appertains to make and. use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which'form a part of this specification.

This invention relates to a machine for aplyin gum-liquid or the like to covers, li s and t e like, so as to establish an air-tight closure of tins for conserves, or for other purpos s. l

In the accompanying drawings :Figure 1 is a side elevation of the machine, Fig. 2 is a front elevation thereof, Fig. 3 shows the gum-liquid ap lying-mechanism in longitudinal'section; 1g. 4 is a plan of the'same. Fig. 5, is a detached top or plan view of the pawl, and, Figs. 6 and 7, are sectional views .taken on thelmes 6-6 and 77 of Fig. 3.

The machine consists chiefly of a frame or standard a, driving pulle s b, cord pulleys and guide. pulleys c, d, e and f for driving the vertical shaft 1 whichhas fixedupon it cord pulleys g and it. These latter pulleys drivethe other movable parts of the machine through other cord pullelys i and 7c and endless cords. The vertical s aft Z is supported in the machine frame a and passes centrally through a revolving table m which is also supported by the machine a. The table m is rotated at intervals by means of a click pawl .9 connected to an eccentric or cam t and engaging the teeth of the ratchet-wheel n. The eccentric or cam is rotated by the shaft Z through the bevelwheels 0, p, q and r. The circular table m is formed Wltlt a number of holes a adapted to receive a lower rotating stamp or holder 1; which is elevated-and lowered by means of the roller w and the cam tr.- Thiscam is fasbevel-wheels p and q.- The machine frame a carries an arm 3 with a head-z in which an upper stamp or holder 21 may move up and down and at the same time be rotated through thepulleys 7c and h. Beneath the arm y is situated the gum-liquid applyingmechanism 22, which is adjustable in vertical and horizontal directions by the screws 1 and 2. v

The gum-liquid a plying-mechanism is shown to a larger sca e in Figs. 3 and 4; it

comprises a shaft 3 with a screw-snail 4 and a drlvmg friction wheel 5 which rotates the shaft 3 when it'touches the revolving stamp 21. the stamp '42, with a lid 6 to which the gumliquid is to be applied lying thereon, is elevated so as to bear against the upper stamp and raise the same. The shaft 3 is supported in a casing 7 having a feeding tube 8 for the gum-liquid which is conveyed to the mouthpiece 9 by means of the feed screw 4. mouth-piece 9 is arranged to work a sto per 10 the bearing shoulder 11 of which cibses the outlet, a spring 12 being provided for kpe ing the stopper down. The upper part 0 t the lower part with other grooves 14. The gum-liquid runs out through the grooves 11; and 14. when the stop )er 10 is raised by the 'lid 6. The machine iramc 0. also carries a reservoir 15 for the gum-liquid in which The wheel 5 bears on the stamp 21 when in the 5,

e stopper is 'or'med with grooves 13 and works anshaft 16 having blades 17 rotated in order to stir the gum-solution by means of the rope pulleys'i and g. The shaft 16 is also furnished with a feed screw 18 encircled by an-open cylinder 20 fastened within the reservoir. By means of the screw the gumliquid is raised to the feeding-tube 19 through which it descends to the gum-liquid applying mechanism always under the same amount of ressure.

he machine works in the followin /mannerz-The reservoir is charged with raw gum, benzin or other dissolving-liquid, and other mixing-substances, which, by means of the stirring-mechanism are homogeneously mixed. The tube 19 is then opened and the gum solution allowed to flow to the applying mechanism 22. The lids 6 to be gummed islrotated, a certain portion of the gum solu and in what manner the same is to be performed I declare that What I claim is 1. In a machine of the type recited the combination of mechanism for applying gum liquid or'the like, a reservoir for the gum liqnid, a n outlet pipe from the reservoir to the .applyingmechamsm, a feed screw and its complemental open cylinder arranged with in the reservoir, and means for rotating the feed screw, whereby the gum liquid is fed through the outlet pipe to the applying mechanism at substantially the same pressure.

2. In a machine of'the type recitedthe combination of holders for rotating and raising and lowering the lids, gum liquid applying mechanism including themouth niece and a stopper for opening and closing 1t, the mouth niece being arranged to contact with a lid, an means for adjustably supporting the applying mechanism in such a way that it can be moved in one direction for operation upon lids of different sizes and in another direction for regulating the gum feed,

substantially as described.

3,111 a machine of the type re :ited the combination of a revoluble table having 0 enings therein for supporting lids, rotatab e holders arranged above and below the taplying mechanism, substantially as described.

4. In a machine of the type recited the combmatlon 01 means for elevating and lowermg and rotating lids, gum applylng mechanism including a mouth piece and a stopper arranged therein and in range of the lids and having lengthwise grooved cylindrical surfaces and a bearing shoulder for opening and closing the mouth piece, substantially as described.

5. In a machine of the type recited the combination of means for rotating and raising and lowering lids, a reservoir provided with an open cylinder and with a rotating feed screw arranged therein, gum liquid ap- )lying mechanism provided with a rotating iced screw and with a mouth piece, a pipe for conveying gum liquid from one feed screw to the other, and a normally closed nozzle for the mouth piece arranged to be opened by the raising and lowering of the lid, substantially as described.

In testimony whereof, I aflix my signature, in presence of two witnesses.
