Specification of Letters Patent.
Patented April 23, 1907.
Application filed November 1. 1905. Serial No. 285,425.
'0 all iUiI/OTIL it may concern:
Be it known that I, WILLIAM G. DUNIIAM,
' a citizen of the United States, residing at Chito which appertains to make and use the same.
.M' present invention relates to car axle box lids of the general character set forth and broadly claimed in my Patent 803,155 of date October 31st, 1905, entitled Oar axle box lic and is particularly designed as a modification of the device disclosed and claimed in my pending ap lication Serial'No. 285,016, filed of date )ctober 30th, 1905 entitled Car'axle box lid.
The present invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims. v In the accompanying drawings which illustrate my invention, like characters indicate like parts throughout the several views.
Figure 1. is a view principally in side elevation, but with some parts brokenaway and with some parts sectioned, illustrating the invention applied to a car axle box. Fig. 2 is a vertical section taken approximately on the line a m .of Fig. 1, some parts being left in full, and Fig. 3 is a view on the same line as Fig. 2, but showing the lid in an open position, some parts being broken awa The numeral 1 indicates the ax e-box and the numeral 2 a portion of the axle. The box in line with its mouth opening is'formed with a transversely extended upwardly profooting fulcrum rib 3 and with laterally spaced bearing lugs 4--. The lid 5, which is preferably constructed of malleable iron, is bulged inward at 6 and is formed at-its extreiue upper edge with a semi-cylindrical i'ulcrum seat 7 that engages and rotates upon the rounded upper edge of the fulcrum ri'o 3. Said lid is also l'ormed with pcri'oratmi lug 8 that projects inward from its bulge 6. W bs on the sides oi the lid at the ends of the l'ulcruin. seat 7 engage the ends or the fulcrum rib 3 to hold the lid in working position against transverse movements.
The numeral 11 indicates a bolt which is provided with. a transversely extended. shaft or head portion that'is journaled in the per- The belt lid and the box, and 'o disposed tiat its line iorations oi the two bearinp lugs a.
l l l 11 and its head 12 constitute what may be termed the T-bolt. The bolt 11 is pro-- vided with a projecting collar or 'l'langc 14: [and its free end works through the perform tion of the lid lug 8 and is provided below the said lug with a stop pin 15. A coiled spring- 16 is placed on the bolt 11 and is compressed between the collar 14 thereof, and the lug 8 of the lid. in this construction, it will be noted that the axis oi the shaft-like head 12 of the T-bolt is located inward oi the plane of the mouth opening of the box and inward oi the axis of the rounded upper edge of the int crum rib 3. In the closed position oi thc'lid,
the spring 16 of the springthrust device v the plane of the mouth opening of the box and extends below the fulcrum rib 3, so that at such time it tends to hold the .lid closed and tends to hold the lid seated the bottom, top and both sides of the face of the mouth opening of the box. Nhenthe lid is moved from its closed position shown in Fig. 2 into its open position shown in Fig. 3, the line of strain of the spring 16 is carried to and then past a dead center with respect to the axis of the head 12 and the axis of the rounded portion of the rib 3, so that in the open position of the lid, the spring exerts a force tending to hold. said lid open. The spring thrust device made up pi the bolt 1 1 and the spring 16 therefore has an angular movement both in respect to the box and to the lid, when the lid is moved from a closedto an open positiomor vice versa. In all positions of the lid, the said spring exerts a force which tends to i n engagement between the seat 7 of the lid 5 and the fulcrum rib 3 of. the box. The in crum rib 3 and the seat 7,. of courr tute thelid hinge, .the axis of which the axis (if-rotation of the seat upon the said rib. The stop pin 15 in the free end of the bolt 11 engages the lug 8 of the lid to limit the extreme opening movement of said lid, as shown in Fig. 3.
What I claim and desire to secure by Let? tors Pa tent of the United States is follows:
1. The combination'with an axle box a lid hinged thereto, of a spring thrust device too reacting directly against apart rigid with the of force intersects the mouth of the box when the lid is closed, end the spring of which thrustsoutwerd on the lid, to open the same, substantially as described.
2. The combination wit'n an axle box and a lid hinged thereto, of aspring hlI IUSLdGVlCQ, reacting directly against 21 pert rigid withthe lid and against a seat in a fixed base of resist ance inward oi the mouth opening of the lid, said spring thrust device having an angular oscillatory movement both in respect to the lid and the box, and so disposed that its line of force obliquely intersects the mouth of the box when the lid is closed, the spring of l which thrusts outward on the lid to open the same, and said lid and its support being provided withmeans whereby movement of the l lid carries said thrust device from one side to l the other of a dead center, substantially as described. 1' i In testimony whereof I eflix my signature in presence of two witnesses:
