To all whom it may camera:
Be it known that I, Euemm E. McWAIN,
a citizen of the United States, residing at Glendale, in the county of Los .Angeles, State of California, have invented a new and useful Mounting for Vibrating Machines, of which the following is a specification.
This invention relates to a mounting for" a vibratin machine for example, a concrete brick mac ine. It 1s now customary to v1 brate concrete brick machines so as to facilitate the elimination of water from the molded brick. "The general object of my invention is to produce a mounting for supporting a vibrating machine 1n such a way as to afford a good support for the machine and combination of without in any way restrictin the vibration or reaction of the frame 0 the machine to the vibrating mechanism. a 5
Further ob'ects of the invention Wlll appear hereina ter.
The invention consists in the novel parts parts to be described hereinafter, all of which contribute to produce an efiicient mounting for vibrating machines. a L
A preferred embodiment of the inventlon is described in the following specificatlon, while the broad scope of the invention is pointed out in the appended claims.
In the drawings Figure ll is a perspective of a vibrating machine supported on mountings embodymg my invention. D
Fig. 2 is a vertical section thr-ough a mounting embodying my invention, and iilustrating detailsof the preferred construm tion.
Fig. 3 is a horizontal section through the mounting taken about on the ll iw 3-3 out Fi ure 2.
eferring to the drawings, 1 represents the frame of a vibrating machine of any conventional type. The upper part of the frame supports molding apparatus 2 and the en tire frame of the machine is vibrated by suitable vibrating mechanism. In the present instance this vibrating mechanism includes a horizontal shaft 3 carryinga wheel 4 with an eccentric weight 5. This shaft is continuously rotated at a relatively high speed by means of-a belt 6 assin over a suitable belt pulley 7 secure to t e shaft. The shaft is supported on suitable frame bars 8 secured to the main frame 1 of h machine Accordin to my invention, I support the frame of t is machine on a plurality of mountings 9. These mountings would usually correspond to the number of legs of the frame, that is to say, each leg is sup- PATENT- oFnc j ported on one of my mountings. Each mounting; may consist of a hollow body 10 (see Figure 2) having a substantially vertlcal peripheral wall 11 composed of a resilient material, preferabl soft rubber. This body is Ipereferably simply a short section of rub 1' tube of large diameter. If, desired, the leg of the machine may be provided directly with means for centering it on the upper end of thebody 10, but I-pre'fer to provide a cap 12 in the form of a circular plate which is provided'on its under side with means for receiving the upper end of the block or tube 10. This means, in the present instance, is in theforrn of an'annulargroove 13 which receives the 'vided further with-a flange 14 which projects down around the outer side of the body 10. This cap 12, is preferably unconnected with the foundation 20, but is provided with suitable means for securing it to the leg 15 on the frame 1. For this purpose I provide the cap 12 with a central bolt 116 and the foot of the leg is provided with a slot 17 which enables the bolt to be shoved laterally intopiaee under the foot when the mounting is being put in position. After the bolt is slid into the slot in this we the nut 18 of the bolt should be tightened up so as to fasten the foot securely to cap.
The mounting is provided with a base plate 19 which may be secured to the floor 20 by means of a central holding-down bolt 21.
brations of the machine, especially the lateral vibrations. On account of the resiliency of the rubber, 1t, of course, permits free verti l vibration of the machine and, f r
the same reason, the body 10 will permit free lateral vibrations. 'This freedom of lateral vibration is enhanced by the natural flexibility of the wall of the body 10in other words, the flexibility of the body in a horizontal plane is enhanced by its tubular form.
It is understood that the embodiment of the invention ClQSCIlbQd herein is only one of the many embodiments this invention may take, and I do not Wish to be limited in the practice of the invention, nor 1n the claims, to the particular embodnnent set forth. 3
'What I claim is 1. In a mounting for supporting a vibrating machine, the combination of a foundation, a block consisting of a hollow body having a substantially vertical peripheral Wall composed of a resilient material, and a cap unconnected with the foundation seating on said body and having means for securing the same to the frame of the supported machine. I
2. In a mounting for supporting a ribrating machine, the combination of a foundation, a block consisting of a hollow body having a substantially vertical peripheral wall composed of a resilient material, a cap unconnected with the foundation seated on the upper end of the body, having means for centering itself on the said body and having means for securing the same to the frame of the supported machine.
3. A mounting for supportin a vibrating machine consisting of a tubular body having a substantially vertical peripheral wall composed of a'resilient material operating to permit vibrations in the-supported machine, a cap plate having an annular recess receiving the upper edge of the body to center the cap plate on the body, and a bolt carried by the cap plate for securing the same to the fi ame of the supported machine.
4. A mounting for supporting a vibrating machine, consisting of a tubular body having a substantially vertical Wall composed of a resilient material, a base plate to be secured to a floor having means for centering the body, and a cap plate unconnected with the base-plate having means on its under face for centering it on the tu-- bular body and having means for securing it to the frame of the supported machine.
A mounting for supporting a vibrating machine, on a foundation, consisting of a body of relatively soft resilient material having a cap seating on said body unconnected to the foundation and secured to the frame of the supported machine.
