'LID FOR JOURNAL-BOXES.

Specification of Letters Patent.

Patented May 28, 1907.

Application filed January 9, 1906. Serial No- 295,295.

To all whom it may concern:

Be it known that I, THOMAS HARRISON SYMINGTON, a citizen of the United States of Ame ica, and a resident of the city of Baltimore and State of Maryland, haveinvented certain new and useful Improvements in Lids for J ournal-Boxos, of which the following is a specification.

My invention relates to a lid for a journal IO box designed to cover the front opening of the standard Master Car-Builders journal box, to be so constructed as to exclude dust at the hinge, and to be held in place against its seat by the torsion of a spiral spring.

In the drawings similar reference numerals indicate the same parts of all the fi ures.

I i ure 1 is a front elevation of the lid in osition upon the box. Fig. 2 is a vertical ongitudinal section of the box and lid. Fig. .20 3 is a lan view of the end of the box carrying the lid Fig. 4 is a horizontal section of the lid through the line ;c-r of Fig. I. Fig. 5 is an elevation of the hinge pin or pintle. Fig. 6 is a perspective view of the torsion sprin in the position it occupies when in use and under tension.

Referring to the drawings. 1 is the box.

2 is'a tooled surface around lhc mouth of the box which forms the seat for the lid.

3 is a lug cast upon the top edge of the box and to which the lid is hingwd. This lug is constructed as shown in Fig 3, partly in full and partly in dotted line, having a central portion which is parallel to the lid, and two supporting portions 4 4 at right angles thereto.

The lugs 13 and 4 are perforated horizontally for the admission of a hinge pin or pintle 5. The rear surfaces of the lugs 44 are curved upon a circle whose center is somewhat forward of the center of the 'pintle 5, so that as the lid which is bent (lowninto close contact with the to of thelug when in contact with its scat wi l clear the rear surface of the lugs 4-4 as it is o cried and avoid friction. The sides of the ugs 4-i are beveled from the front rearwardly for the same pur pose. The front edge of the lug 3 forms a cam surface for contact with the spring. by which the lid is held upon its seat.

6 is a vertical portion, having a small area. 7 is a curved portion, struck from about the same center as that of the rear surface of the lugs 44, that is to say, the center of which is in advance of the center of the pintle 5. The maximum point of tension of the spring is attained when the shoeis in contact with the upper edge of the cam surface 6.

8 is the id, provided upon its interior face with a machined surface 9 -9 which makes contact with the seat 22 of the box to close the aperture.

10 is a flange, extending at right angles from the interior face of the lid, just inside of the machined surface 9 on the bottom and two sides. m

In the center of. the lid 8, there is a raised portion or housing 11,.designed to contain the coils of the sprin abov which is a housing 12.which covers t 1e lugs 3 and 44.

1 313 are hinge lugs cast integral with the the lid on each side of the housing 12 and which are provided with central perforations to admit the pintle 5. Upon the rear edge of the housing 12 is a li -14c, which, as shown 1n Fig. 6, stands imme iately over the pintle and contacts with the top of the lug 3.

and the lugs 44. The cover or lid is made of malleable material, and when the lid is in the position shown inFig. 6, thislip 14 is hammered down into close contact with the top of the lug 3 so as to make a practically dust (proof joint. This close joint is preserve by the fact that the curves of the rear surfacespf the lugs 44 are struck from a center in advance of the center of'the intle 5 sothat the moment the lid is raised t e lip 14 begins to clear and friction with the lugs 3 and 4-4 is prevented.

l515--are lips, semi-circular in form,- w lneh project from the rear edges of the hinge lugs 13l3 of the lid, and stand opposite to the inclined surfaces of the lugs 4-4. When the lid is placed in position upon the box, these lips l5-15 are hammered down against the curves of the lugs 44, so as to make a practically dust proof joint therewith. As the lid is raised the bevel of the lugs, shown in full and dotted lines in Fig. 3, will cause the lips 1515 to clear said bevel surfaces and move freely without contact therewith. The bevel surfaces will permit the lid to be raised to a position where there IS a clearance, and then, when the lips 1515 are hammered down into contact with the bevel surfaces, these lips will bend, and bear and the housing 11 of the lid and the free ends 17 -17 are held firmly within the overhanging lugs 1818 which are cast upon theinterior of the lid.

19 is a shoe, secured upon the loop of the spring to take the wear of the cam surfaces 6 The. spring must be placed under torsional tension in order that it may be secured within the lid. The ends are pressed together so .as to engage the lugs 1818, and by their own elasticity, hold themselves in place. The

shoe 19 is then placed in contact with the point 6 of the lug 3, and pressure applied to,

bring the hinge lugs into register. This pressure will compress the spring into tension. The pintle 5 may then.be passedthrough the hinge, and its split end bent'and clenched upon the. recessed boss which forms one side of the ligl portion of the hinge so as to lock it in place and cause it to turn therewith. I 7

It will be noticed that this form of structure enables me to provide my lid with a long, flexible, torsional spring, having a large limitof elasticity and a consequent long life. It also provides a springwhieh is independent and detachable, which may be replaced by another of the same character on the road by any train hand. I

Having thus described my invention, what I claim, and desire to secure by Letters Patout is:

1. Ina journal box the combination of a hinged lid, an independent torsional spring mounted upon the interior oi'the lid, but detachable therefrom, although secured thereto, and which contacts with the cam surface upon the box to hold the lid upon its seat;

2. In a journal box the combination of a lid attached tov the box, with a torsional spring interposed between the lid and the box and a ham on one of said parts co-opcrating with the spring to hold the lid upon the seat.

3. In a journal box, the combination of a lid secured to the box and-bearing upon a seat thereon, with a torsional spring one end of which bears upon the box andaetingiupon a camon the box and the other end upon the lid and holds the lid upon its'seat'.

' -4. In a journal box the combination of a v lid'which is hinged to the box above the opening; a torsional spring attached to the interior surface of the lid, a cam surface upon. the box bearing upon the free end of the" combination of a lid designed to close the opening hinged to the box, the box portion" 0 the hinge being beveled away fromthe lid upon the sides, the lid portion of the hinge being provided with lips which may be; bent into contact with sides of the box por -1'3 vtion when the lid is closed, and which by virtue of the bevels of the sides of'thc. box

portionwill clear them as the lid is openedi 7. In a journal box the combination of a lid with a double torsional spring acting upon a cam on the box, each leg being coded, and

bent so as to form a loop between them, the

free ends being so bent as to hold themselves-- in place by their own elasticity.

8. In a journal box the combination wardly projecting hooked lu of a lid having a central housing and two in s the hooks'be"- ing located opposite each other, with a dollble torsional spring having a central lip a'nd I 1 two coil legs, the coils of the spring being seated in the housing of the lid and the free 1 legs of the spring being seated and held by the hooks upon the interior of the lid, the-lip}- of the sprin being free to exert pressurcupon the box, su stantially as described.

9. A journal box lid hinged to the box, thei pintle of the hinge having its free end] clenched upon the hinge lug of the lid, so as to be fast thereto and to turn therewith.

10. In a journal box the combination of a lid hinged thereto, by a lug on the box and two lugs on the lid, one of the lid lugs beings 9; provided with a ,notch on its exterior surface,"

and a pintle passing through the hinge lugs:

and having its free end clenched into the notch on the exterior of the .lid lug-, whereby the pintle will be secured in the hinge and hold fast to the lid.
