DUST-GUARD FOR PULVERlZlNG-MACl-HNES, 86C.
$PECIFICATION forming part of Letters Patent No. 331,393, dated December 1,1885.
Application filed April '21, 1835.
ToaZZ whom it may concern: 7
Be it known that I, RYERsoN D. Garns, a citizen of the United States, residing at Ohicago, inthe county of Cook and State of Illinois, have invented certain new and useful Improvements in DustGruards for Pulverizing- Machines, 8m, which are fully set forth in the following specification, reference being had to the accompanying drawings, in which- Figure l is an elevation of a pulverizingmachine having my improved dust-guard ap plied thereto; Fig. 2, a vertical transverse sectional view of the same; Fig. 3, a plan of the upper guard, a portion of the shield being broken away to show the construction; and Fig. 4, a plan view of the lower guard.
Like letters refer to like parts in all the figures of the drawings.
My invention relates to dust-guards for shaftbearings, its object being to provide means for effectually preventing the access of dust or small particles of material which would ren der them liable to heat and cut, and thereby be destroyed. V
I will now proceed to describe a construction in which I have practically carried out my invention in one form, and will then specifically point out in the claims the features which I believe to be new and desire to protect by Letters Patent.
In the drawings I have shown my improved dust-guard as applied to a pulverizingma chine of the character set forth in an application filed by me January 21, 1885, Serial No. 153,562, reference to which is made for a description of the said machine. It is obvious, however, that my invention is equally applicable to other machines having a vertical shaft or shafts, the bearings of which it is desirable to protect, as hereinbefore set forth.
In the drawings, A represents a shaft of the machine, having its upper bearing at a, and its lower bearing at a. In order to provide effectual dust-guards for these bearings, I have devised the following means: The guards are essentially the same in their general nature, differing somewhat, however, in detail. The guard for the lower bearing consists of a cup, B, having a circular groove, 1), surrounding the bearing and partially filled with water or other liquid by means of the pipe I), or other- -Serial No. 163,666. (No model.)
ing flange, b", which enters the groove in the cup 13 and extends below the level of the liquid therein, acting in conjunction with the said liquid to form a dust-seal which will ef- 6o fectually prevent any passage of dust from the body of the machine into the bearing in an obvious manner. The guard for the upper bearing consists of a similar grooved cup, 0,
and attached to the frame of the machine in any suitable manner below the said bearing, and supplied with water or other liquid through the medium of the pipe 0, or otherwise. This grooved cup operates in conjunction with a shield or guard, 0, attached to the shaft above the cup and below the bearing. This upper cup, 0, however, is provided with two grooves, the lower one, a, to receive the water which, in conjunction with the depend ing flange c of the shield, forms the dustseal,
and the upper one, 0 to collect the oil which drops from the bearing above it, the guard 0 being provided with an extension or flange, c, which extends over the said groove 0" in order to conduct the oil which falls from the hearing on the upper side of the shield to the groove. In order to prevent this oil from filling the upper groove and overflowing into the lower one, causing that to overflow, and
in order to prevent waste of the lubricating material, the oil as it collects in this groove 0 is withdrawn therefrom by means of a pump, D, connected to the said groove by means of a pipe, d, and driven in any suitable manner,
preferably from the driving-shaft A of the machine, as shown. The pump D withdraws the oil from the groove 0 and returns it, by means of the pipe d to the receptacle D above the upper bearing, a, which contains the lubricant for the said bearing.
It will be observed that the dust-seal of the cup 0 not only prevents any dust from passing from the body of the machine into the upper bearing, but it also prevents any passage of the oil from the said bearing into the body 1C0 of the machine, acting for this latter purpose in conjunction with the pipe D, which returns This 55 the oil from the grooves e to the bearing.
This latter result is a very desirable one, more especially under certain circumsta11cessuch, for instance, as where the machine is being used to pulverize an ore which must subsequently be submitted to other processes to extract the metal therefrom, with which processes the presence of any oil which might drip from bearings would most materially interfere.
It is obvious that although I have shown my improved dust-guard as applied to a particular form of machine, its application is not limited to this particular form, it being indeed applicable, as hereinbefore stated, to any machine having a vertical shaft, the bearings of which it is desirable to protect, as hereinbef'ore set forth. It is also obvious that various mechanical modifications may be made in the details of construction without departing from the principle of my invention, and I therefore do not wish to be understood as limiting myself to the precise details of construction hereinbefore described, and shown in the drawings.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. The combination, with the shaft A, of the double-grooved cup 0, surrounding the same below one of its bearings and having its lower groove filled with water or other suitable liquid, and a shield or guard, G, attached to the said shaft and having its lower edge arranged in the said lower groove below the level of the top of the liquid therein, and provided with a flange, 0, extending over the upper groove, substantially as and for the purposes specified.
2. The combination, with the upper bearing of the pulverizing-shaft A, of a cup arranged below the said bearing to catch the oil which may drip therefrom and a pump con nected with the said cup and with the oil-receptacle above the bearing to return the dripoil to the said receptacle, substantially as and for the purposes specified.
3. The combination, with the upper bean ing of the pulverizing-shat't, of a receptacle arranged below the said bearing to catch the drip therefrom and a water-seal arranged between the said receptacle and the lower portion of the machine to prevent any access of .dust to the bearing, or of oil to the material operated upon, substantially as and for the purposes specified.
