DRUM CONSTRUCTION FOR SCALES.
Specification of Letters Patent.
Patented Dec. 19, 1911.
Application filed July 8, 1910. Serial No. 571,007.
To all whom it may concern:
Be it known that I, BENJAMIN D. EMAN- UEL, of Anderson, county of Madison, and State of Indiana, have invented a certain useful Drum Construction for Scales; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings.
The object of this invention is to provide an improved means for the mounting of the cylindrical chart in drum scales, so that said chart will be carried by a single frame mounted on a spindle. The construction of said drums requires a great degree of accuracy in order that they may revolve easily and be truly balanced and not engage the casing which usually surrounds the drum.
The nature of the invention will be understood from the accompanying drawings and the following description and claims.
In the drawings Figure 1 shows a drum which is in section in some parts and other parts are in elevation, the chart being broken away. Fig. 2 is an end elevation on a larger scale. Fig. 8 is a view like that shown in Fig. 1 of a modified form. Fig. 4 is an end elevation of what is shown in Fig. 3.
There is shown herein two drums on a single spindle 10, which has a pinion l1 secured to it whereby power is transmitted to the spindle for revolving the drum. So far as this invention is concerned, the two ends of the two drums in the one construction are arranged in substantially the same way. On the spindle a single chart supporting frame is secured at a point about midway of the ends of the chart 12. This frame in the first two figures is made up of an aluminum casting having what may be called a hub portion 13, a central portion 14 and arms or spokes 15 diverging and extending in opposite directions to the ends of the chart where said arms are secured to rings or bands 17 and the ends of the chart are secured on and about said ends or bands. By forming the frame in one piece of casting, when the rings or bands are secured thereto,
the whole support of the chart on the spindle constitutes one solid single frame, the various parts of which are in rigid relation to each other so that it will hold the chart absolutely true. Some of the arms are provided with slots 18 for holding adjustably sliding weights 19 movable toward or away from the central part of the frame, so that by adjusting said weights the drum can be accurately balanced on the spindle.
In Figs. 3 and 4 showing a modified form, the spindle and chart, rings or bands are unchanged, but the frame on which the rings or hands are mounted is formed by punching the same out of a single sheet of thin metal, that is, a frame with eight arms is punched out of the sheet of metal, so that a side elevation will be substantially as shown in Fig. 4. It has a central web portion 25 and from that the arms 26 are turned alternately at opposite inclinations so that their ends will extend out and be secured to the rings or bands 17. Hence four of the arms will extend to one band or ring, and the other four to the other band or ring. A central hole is punched out for the insertion of the spindle 10, and that punched out portion 27 is in the nature of a hub which is secured to the spindle in the drawings by solder 28, although the same may be secured in any desired manner. Some of the arms have the slots 18 and weights 19 like the other form for the same form of the device and for the same purpose. The weights 19 are placed on the arms of the frame on both sides of the point thereof which is secured to the spindle so that the frame and drum may be balanced longitudinally as well as transversely. The longitudinal balancing is desirable because the frame is secured at a central point midway of the ends of the drum and unless the two ends of the drum are balanced it might not revolve smoothly.
I claim as my invention:
1. A drum for a drum scale including the combination with a spindle and a chart, of a single frame for supporting the chart on the spindle which frame consists of a central portion secured to the spindle about midway of the chart, a series of arms extending from said central portion in opposite and oblique directions, and a band mounted on the ends of each series of arms.
2. A drum for a drum scale including the combination with a spindle and a chart, of a single frame for supporting the chart on the spindle which frame is punched out of a single sheet of metal so as to have a central portion surrounding and secured to the spindle midway of the chart and a series of radial arms which are alternately bent in opposite oblique directions so as to form two diverging series of arms, and a band secured to the ends of each series of arms.
3. A drum for a drum scale including a spindle, a cylindrical chart, a single frame for carrying said chart Which is secured to the spindle, and radially adjustable Weights in connection With said frame for balancing the same.
4. A drum for a drum scale including the combination With a spindle and a chart, of a single frame for supporting the chart on the spindle Which frame consists of a central portion'secured to the spindle about midway of the chart, a series of arms extending from said central portion in opposite and oblique directions, a band mounted on the ends of each series of arms, and an equal number of radially adjustable Weights mounted on said arms on each side of the central portion thereof, whereby the drum may be balanced angularly and longitudinally.
In Witness whereof, I have hereunto affixed my signature in the presence of the Witnesses herein named.
