JIN S. MILLER, OF ST. LOUIS, MISSOURI.
COFFEE-ROASTER.
Specification of Letters Patent.
Patented June 19, 1906.
Application filed March 6, 1906. Serial No. 304,545.
To all whom, it mia/y concern,.-
Beit known that I, JOHN S. MILLER, a citizen of the United States, and a resident of St. Louis, Missouri, have invented certain new and useful Improvements in Coffee- Roasters, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.
My invention relates generallyT to coffeeroasters, and more particularly to a construction which will permit of the ex ansion and contraction of the main shaft t at extends longitudinally through the rotating cylinder. i
The object of my invention is to provide a roller-bearing at the forward end of the shaft, which roller-bearing supports the box on said shaft and permits the same to move longitudinally as the shaft expands or contracts without binding on any of the fixed parts of the roaster.
A further object of my invention is to provide adjustable supports for the head that is positioned in the front end of the roastingcylinder by means of which the strain of said head is removed from the forward end of the shaft and which arrangement also provides for a tight joint between said head and the forward end of the cylinder.
To the above purposes my invention consists of certain novel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of a coffeeroaster embodying my improvements. Fig. 2 is a vertical section taken on the line 2 2 of Fig. 1. Fig. 3 is an enlarged detail section taken on the line 3 3 of Fig. 2. Fig. 4 is an enlarged detail section taken on the line 4 4 of Fig. 1.
Referring by numerals to the accompanying drawings, 1 designates the furnace of the roaster; 2, the front plate thereof; 3, the rear plate, and 4 the horizontally-arranged cylinder that is held for rotation in the fur- `nace between the front and rear plates. The
front end of the cylinder 4 is open, and it terminates in a circular opening 5, formed in the front plate 2. Normally closin the front end of the cylinder 4 `is a circular ead 6, provided on its edge with a fiange 7 and at its upper end with a short spout 8. Formed in the center of the head 6 is a horizontally-arranged bearing 9, in'which is journaled the forward end of the shaft 10, which extends longitudinally through the cylinder 4 and which is journaled at its rear end in a bearing 6o 11, formed on the outer face of the rear wall 3. A head 12 'is fixed in the rear end of the cylinder 4 and is carried by a shaft 10, an a spider 13, fixed upon the forward end of the s ward end of said cylinder. Fixed upon that 'portion of the shaft 10 that is journaled in the bearing 9 and which extends in front thereof is a bushing 14, of brass or analogous material, and held upon said bushin means of a set-screw is a collar 15, whic engages against the front end of the bearing 9 and holds the rear end thereof a ainst the bearing 13, thus maintainin the ead 6 in position in the forward end o the cylinder 4. 7 5
Fixed upon the sides of the front plate 2 and extending outwardly therefrom are brackets 16, the forward ends of which support the cross-bar 17, having formed in its top surface a longitudinally-extending groove 8o 18. Fixed upon the top of the bar 17 at each end of this groove are standards 19,
the upper ends of which are united by a removable cap 20. Arranged to roll transversely within the longitudinally-extending groove 18 is a roller 21, and mounted thereon is a rectan ular bearing 22, throu h which passes the orward end of the sha t 10 and the bushing 14 thereon. A collar 23, held by a set-screw, is fixed upon the end of the shaft 9o 10 outside this bearing 22.
Located on the front face of the front plate 7 a suitable distance to each side of the center thereof is a roller-bearing, which supports the head 6, and each bearing comprises a short plate 24, in which is formed a longitudinally-extending slot 25, and passing therethrou h is a set-screw 26, b means of which the p ate 24 is locked to t e plate 2. The
upper end of each plate 24 carrles a roller 27, rco
on the peri hery of which rests the flange 7 of the hea 6. A lug 28 is formed integral with the plate 2 immediately below each plate 24, and passing throu h said lug and caring against the lower en of the plate 24 ro 5 is an adjusting-screw 29.
The bearin 22, carried by the roller 21, will move bac wardly and forwardly, following the expansion and contraction of the shaft 10, due to the heating or cooling of the 1 1o furnace, and whenever this movement takes place the roller will travel hackwardly and aft 10 inside the bearing 9, carries the for- 65 by 7o and from the periphery of the flange 7 by V ed coffee from the cylinder 4, as shown by rangement provides for an even wear besaid hea and the front end of the cylinder 4.'
forwardly in the groove 18. Thus the expansion and contraction-of the shaft is actuated without undue strain to any of the operating parts of the roaster.
The head 6 is properly centered upon the shaft 10, and the strain or weight of said head is removed from its bearing upon said shaft by the provision of the plates 24, carrying the rollers 25. These plates are adjusted to loosening the set-screws 26 and then manipulating the adjusting-screws 29, after which the set-screws 26 are tightened to lock the plates in proper position. When the head 6 1s reversed in position to discharge the roastdotted lines in Fig. 2, the periphery of the flange 7 rides upon the ,rollers 27. This artween the shaft and the bearing 9 in the cen-L ter of the head 6 and also allows a comparatively t' ht joint to be maintained between- 2. In a coffee-roaster, constructed with a longitudinally-extending shaft and a cylind er@ carried thereby, a journal-box in which the i forward end of the shaft is supported, and a i roller supporting said journal-box; substan- ,l tially as specified. l
3. In a coffee-roaster, constructed with a lonUitudinally-arranged cylinder, a head normally closing the forward end of said cylinder, a flange integral with the edge of said head, and rollers carried by the front wall of the roaster on which rollers said flange engages, and which support said head; substantiallly as specified.
4. In a codec-roaster, constructed with a longitudinally-extending shaft and a cylinder carried thereby, a head normally closing the front end of the cylinder through which head passes the shaft, a Harige inte ral with the edge of the head, plates a justably mounted on the front of the roaster, and rollers journaled on the upper ends of said plates, which rollers are engaged by the edge of the Bange; substantially as specified.
5. In a coffee-roaster, constructed with a Alongitudinally-extending cylinder, a rotating head normally closing the forward end of said cylinder, and means whereby said head is adjustably held in osition within the cylinder independently t ierefrom; substantially as speciied.
6. A cofee-roaster, constructed with a longitudinally-extending shaft, a cylinder carried thereby, a head normally closing the forward end of said cylinder, means whereby said head is held in position inde endent of the cylinder, and a longitudinaliy-moving journal-box supported in front of the head and supporting the forward end of the shaft; substantially as specified.
In testimony whereof I have signed my naine to this specification in presence of two subscribing witnesses.
