DUST-GUARD.
Specification of Letters Patent.
Patented Oct. 18, 1910.
Application filed January 24, 1910. Serial No. 539,827.
To all whom it may concern:
Be it known that I, LAOEY Y. WILLIAMS, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented new and useful Improvements in Dust-Guards, of which the following is a specification.
The object of my invention is the provision of an improved dust guard for car journal boxes which shall be adapted to be inserted withina chamber at the rear of the journal box and to frictionally engage the journal, said guard to be of very simple construction, cheap in first cost, durable, and effective in maintaining a close frictional contact with the journal under all conditions, and especially when the edges of the guard have become worn away in service.
The invention consists in certain novelties of construction and combinations of parts as hereinafter set forth and claimed.
The accompanying drawing illustrates an example of the physical embodiment of the invention constructed according to the best mode of procedure I have so far devised for the purpose.
Figure 1 shows in section a journal box and dust guard, and a journal in elevation, also part of an axle. Fig. 2 is a plan view of the com lete guard showing the relative positions of the parts when the same is upon a journal. Fig. 3 is a plan view of the guard removed from the journal and with one corner plate removed to disclose the location of a spring. Fig. 4C is an end view of the guard. Fig. 5 is a perspective view of the spring.
Referring to the figures, the numeral 1 designates a car journal box of well known construction; 2, the journal of a car axle; 3, a dust guard chamber at the back end of the box; 4, a removable wedge for closing the top opening of the chamber; 5, my improved dust guard shown in section within the chamber; 6, the two L-shaped sections of the guard made of any suitable material, preferably of wood, each section being a complement of the other; 7, the long armof a section; 8, the short arm of a section; 9, the semicircular bearing edge of a section; 10, the guide or cover plates secured to the opposite surfaces of the short arms of the sections by screws and being extended so as to overlap the long arms and hold them in planes parallel with the short arms; 11, recesses in the body of the material in the long arms; 12, extensions of the recesses lengthwise of the arms; 13, circular recesses in the short arms adjacent the recesses in the long arms; 14, springs each having a coil 15 located within the recess in the short arm, and a coil 16 with an extension 17 located within the recess and extension thereof in the long arm; 18, a staple passed over the coil 15 and seated in the material of the arm, said staple loosely engaging thewire of the spring when desired so the wire can move within the recess about the axis of the coil and through the staple; 19, a pin passed through the material of the long arm and above the extension 17 to hold the same in place.
It will be observed that each coil 16 of a spring located within the recess in the long arm of a section is so disposed that when the two L-shaped sections are forced apart the coil will be wound up or contracted and in tension, thus insuring the storing up of suflicient energy in the coil to hold the L- shaped sections against the journal.
The two L-shaped sections are oppositely disposed in the same plane, and each of the two springs performs the triple function of uniting the two sections, holding the edges of the long arm in contact with the edge of a shortarm, and also controlling and limiting the longitudinal sliding movement of one section relative to the other section.
It is obvious that the two sections normally will be held in the relative positions shown by Fig. 2 wherein the opening is a circle which conforms to the circumferential surface of the axle journal so that the bearing edges will frictionally engage the journal and prevent the passage of any foreign substance, such as dust and dirt, to the interior of the journal box.
In assembling the parts the guard is placed within the chamber at the back end of the box, and when in position the parts are in the relative locations one to another shown by Fig. 3. The journal is then inserted into the box and forces the sections into the relative positions shown by Fig. 2.
From the foregoing description taken in connection with the drawing it is clear that I have provided a very simple, cheap, dura- I circle and frictionally engage the journal at all points of its circumference and exclude dust and dirt.
hat I claim is:
1. The combination in a dust guard, of two complemental L-shaped sections, each section having a semicircular bearing edge and said sections being oppositely disposed to each other to form a substantially circular opening, said sections having recesses adjacent their meeting edges; and springs each having two coils located within the recesses and overlapping the said meeting edges; the coil of relatively small diameter of each spring being so disposed that When the sec tions are forced apart the coil will be Wound up and under tension.
2. The combination in a dust guard, of
tWo complemental L-shaped sections, each section having a semicircular bearing edge,
and said sections being oppositely disposed to each other to form a circular opening, said L-shaped sections each having recesses open to the edge of the sect-ion; springs each having a coil Within each of the recesses and overlapping the edges of the sections; and means for holding one of the coils so it cannot bodily rotate, the other coil being free to rotate about its axis Within the recess.
In testimony whereof I affix my signature in presence of tWo Witnesses.
