BRONZING-MACHINE.-

SPECIFICATION forming part of Letterslatent No. 702,551, dated June 17, 1902. Application led August 2'7, 1901'. ASerial No. 73,424.V (No model.)

To all whom it may concern:

' Be it known that I, GEORGE HABE, a citizenj of the United States, residing at Los Angeles, in the county of Los Angeles and State'of Cali-V fornia, have invented new and useful Improvements in Bronzing-Machines, of which the following is a specication. Y

This invention relates to machines for applying ornamentalpowder or dust to printed matter, and pertains to means for securing uniform application of the powder to Athe lprinted sheet, improving the appearance of the work done, and-securinggreater economy of time and material, and for preventing'the escape of the bronze-dust or other powder into the open atmosphere.

Itincludes, first, means for applying theA dust or powder to the printed matter at the.

desired place or places with greater evenness'` with the greatest convenience be returned to the bronze-fountain.

The accompanying drawings killustrate my invention.

Figure I is a view of a bronZing-machine embodying my improvement. Portions 'of the machine are omitted to expose the parts in whichl my inventionresides. Fig. II is a' fragmental View showing the sprayer and the sprayer-shaftdetached.l One 4section of the4 sprayer is shown complete and a fragment of another section is shown. Fig. ,III is a section on line III III, Fig. Il, looking right in the direction of the arrow. Fig. IV is an end elevation of the bronzing-machine. The directions in which certain-parts are driven relative to leach other are indicated. Fig. V is a sectional detail on line.V .V, FigIV, to shovv` the means for allowing the apron-rollerto be removed.

box.

2 indicates the ordinary plush fountainroller, which, it is to-loe understood, is driven in thedirection of the arrow by the usual ratchet-and-cam device.

t 3 Al indicate the knives, which, with the 1 indicates the ordinary bronze fountain or l ofA the bronze fountain, receptacle, or box -1 sisting in "a barrel formed in two end disks or heads 6 7, to which is secured at intervals spraying Scrapers or blades 8. 9 indicates the shaft upon which said sprayer is mounted and whichshaft is driven by suitable means at a high speed relative to the speed of the plush' fountain-roller 2. It is to be understood that the sprayer is preferably formed in sections, as indicatedV in Fig. Il, which are detachably mounted on the shaft 9 and held by set-screws a. Any of the sections may be used or omittedrat pleasure, thus to determine the place or places across the printed sheet at which the bronze is to be applied.

The sprayer may be runat any suitable.

speed. I prefer a speed for the sprayer from three to six times as fast as the plush roller 2, so that the sprayer-blades 8 will 'overtake the piles of the plush roller andwill scrape or brushtherefrom the bronze-powder carried by the plush and will project said powder against the printed sheet, (not shown,) which` passes through the bronzing-machine for that purpose.

do not limit myself toany particular con-v struction of the bronzing-machine nor to any specific construction of the parts of my invention. l

l0 indicates the ordinary cylinder of the bronzing-machine, and l1, l2, and 13 the ordinarydusters which are common in the ordinar-y bronzing-machine vand which remove f the bronze-dust is thrown by the dusters ll, 412, and 1,3. A

17 indicates an endless apron or` belt, preferably of plush, having one face arranged in the path of the bronze-dustwhich'is brushed fromthe printed sheet by the dusters 11, 12,

IOO

18 indicates a dust-brush to brush the dust from the endless apron or belt 17.

Preferably the belt 17 runs at a low speed and the dust-brush 1S at a relatively high speed.

19 indicates a removable dust-receiving receptacle in the l'orm of a drawer below the apron and dust-brush to receive the bronzedust which is brushed from the dust-belt 17.

Itis to be understood that the fountainroller 2 is intermittently driven at a low speed by mechanism hidden by the body of the machine in Figs. I and IV. The machine-body is broken to show a part 2O of such mechanism.

2l indicates a higlrsgeed pulley to drive the sprayer 5, 22 a low-speed pulley to drive the dust-receiving belt 17, and 23 a high-speed wheel to drive the dustbrush 1S.

In practical use the bronzing-machine is operated in the ordinary way, the printed sheets being passed in over the table 2t and the cylinder 10 and passing 'through the machine and out at the delivery 25. The slowly and intermittently revolving fountain-roller 2 carries from the bronze-fountain 1 the requisite amount of bronze-powder, which by means of the sprayer 5 is stripped from the piles of the plush roller and projected onto the printed sheet (not shown) in perfectly even and suitable distribution over the desired surface ot' the printed matter. The sheet then passes on between cylinderlO and the dusters l1, 1:2, and 13 and to the felt roller 14, which delivers the sheet to the delivery apron or plate 25. The bronze-d ust remaining on the unprinted portions ot the sheet after it has passed the sprayer 5 is brushed oi by the dusters 11, 12, and 13 and thrown over against the face of the plush belt or apron 17, which face moves slowly toward the revolving dustbrush 1S, which revolves at a sufficiently high speed to brush from the plush apron 17 the bronze-dust carried thereby, thus delivering said dust to the dust-receiving receptacle 19, which from time to time will be removed and its contents poured into the bronze-fountain 1, thus avoiding any inconveience or any such disturbance of the dust as might cause the same to escape into the surrounding atmosphere. This arrangement avoids all necessity of stoppage of machine and presses heretofore necessary for the purpose of clearing the machine of the surplus bronze.

2G indicates screws bywhich the blades 8 of the sprayer are attached to the end disks l, which carry said blades. Preferably the faces of the blades lie tangentially, as indicated in Fig. II, in order that they may be lnost effectively brushed along the piles to remove therefrom the bronze-dust.

Suitable adjusting and releasing devices are provided by means of which the endless apron may be adjusted to appropriate tension and may be released and taken out of the way to allow access to the interior of the bronZing-machine through the rear doors 27.

For this purpose 28 indicates a bearing-plate adjustably fastened to the frame 29 ol the machine by bolts 30, which pass through slots 51 in said bearing-plate. The frame is provided with a hole 32, through which the upper roller for the belt or apron 17 is carried. When it is desired to gain access to the interior of the machine, the bearing-plate 29 will be released, the roller 33 will be withdrawn through the hole 32, thus allowing the endless apron to be lowered out of the way and any accumulations of bronzingdust which may have occurred inside the machine may be removed. Then the roller 33 will be passed back into the machine through the hole and brought into appropriate position in the belt, and the roller-shaft 34 will be inserted in an adjustable bearing on the far ther side of the machine-frame, and then the bearing-plate 2f) will be brought to the appropriate position and secured in place by the screws 30.

lVhat I claim, and desire to secure by Iletters Patent of the United States, is

1. In a bronZing-machine, the combination with a plush fou ntain-roller; of a sprayer provided with blades to remove the dust from the fountain-roller and to throw it onto the surface which is to receive the same.

2. The combination of the fountain-roller, of a spraying-roller, and means for rotating said spraying-roller at a speed greater than that of the fountain-roller.

3. In a bronzing-machine, a sprayer comprising a barrel furnished with Scrapers or blades.

4. A sprayer for a bronzing-machine consisting in heads and blades fastened to said heads to form Scrapers for removing the dust from the piles of the fountain-roller.

5. The combination with the cylinder and duster of a bronzing-machine, of an apron having a face located in the path of the dust thrown by said dusters; m'eans for moving the apron; and means for removing the dust from the apron.

G. In a bronzing-machine, a dust-receptacle; a dust-catching apron arranged in the path of the dust, and means for moving said apron to deliver the dust to the dust-recep tacle.

7. A bronzing-machine furnished with a removable dust-receiving receptacle; a moving apron to receive the dust thrown by the dusters of said machine; means for moving the apron at one speed; and a dustbrush arranged to brush the face of said apron and to deliver the dust therefrom into said removable receptacle.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, at Los Angeles, California, this 21st day of August, 1901.

GEO. HABE.
