' JOURNAL-BOX HINGE-PIN.
Specification oflletters Patent.
Patented Oct. 11', 1921.
Application filed August 16, 1920. Serial No. 4oc,92a.'
To all whom it may concern:
Be it known that I, WILLIAM F. KmsEL, J r., a citizen of the United States, and residing at Altoona, Blair county, State of Pennsylvania, have invented certain new and useful Improvements in Journal-Box Hinge-Pins, of which the following is a specification.
This invention relates to an" improved hinge pin for pivotally attaching the lids pi ournal boxes of railway cars and the As now generally constructed the lids of journal boxes are secured in position by a solid pivot bolt which passes through alined cylindrical openings in the hinge members of the lid and a similar opening in an ear or lug on the journal box, the bolt being held in place by a flat split key or cotter pin inserted in anopening in the end of the bolt. This construction possesses certain defects anddisadvantages. Workmen frequently neglect to ap ly a ke or the ke becomes worn out or roken, t e pivot bo t consequently dro s out and 1s lost and as a result the lid a so becomes detached and lost and the journal box is open for the access of dirt and grit. The ordinary pivot bolt also becomes worn by use, causing considerable noise and rattling and such .rattlin motion of the parts further wears out the bolt and the lid.
The present invention aims to overcome these difliculties by roviding a pivot pin or bolt with which no astening key is required, the improved pin comprising two spaced resilient arms rigidly secured to ether at one end and having shoulders on t eir outer surfaces near their opposite ends. The arms are so arranged that they can be pressed together and inserted through the cylindrical openings in the lid and journal box and when in position a head on one end of the pin and the shoulders on the other will prevent withdrawal or longitudinal movement of the pin. The outer surface of the arms are constructed to fit the cylindrical openings in the hinge members of the lid and the journal box and are held against the walls of such openings by the spring action of the metal. Various advantages of this construction will be later described.
The invention is set forth'in detail in the following specification and illustrated in the accompanying drawings in which:
Figure'l is a plan view partly in section of a lid and the associated parts of a journal box having the present invention applied thereto;
Fig. 2 is a view in side elevation of the portion of the construction shown at the ri ht in Fig. 1;
ig. 3 is a side elevation of one form of pivot pin which may be employed; Fig. 4 is a sectional view on the line H of Flg. 3;
Fig. 5 is a plan view of the pivot pin shown in Fig. 3;
Fig. 6 is a side elevation of another form of p1vot pin which may be employed for carrying out the present invention.
Referring. to the drawings in detail, 10 represents the lid of a. journal box which is provided with hinge members 12, such hinge members being provide-d with alined cylindrical openings through which a pivot pin is adapted to be inserted. The journal box, generally designated by the numeral 13, is provided with an car 14 shaped so as to fit between the hinge members 12 of the lid. such ear also being provided with a cylindrical opening through which a pivot bolt may be inserted, it being understood that the openingsin the hinge members 12 and the car 14 are adapted to be arranged in line so that the pivot bolt may be insertedthrough the openings in these parts for pivotally securing the lid to the journal box. A spring 15 is secured to the lid 10 in any suitable manner, such spring being of the usual construction and serving to hold the lid in an open or closed position.
The hinge pin which I prefer to employ and which constitutes the novel feature of the present invention consists of two resilient arms 16, 16, which are spaced apart a slight distance and which at one end are rigidly secured together and preferably made of an integral piece of material. Each of the arms 16 near its free end is provided with a shoulder 19 and beyond the said shoulder each of the arms is tapered as shown at 20. The outer surfaces of the arms are curved so as to closely fit the contour of the openings, the pin as a whole therefore being substantially cylindrical in form as will appear from Fig. 4 of the drawing. The pin, if desired, may be pressed from sheet metal, as shown in Figs. 3, 4 and 5, or the same may be constructed of a solid bar split longitudinally throughout its length or if desired, through a part of its len h as shown in Fig. 6. The split should at east extend for a sufficient distance to give the necessary resiliency to the arms lti. It is also apparent that such pins may, if desired, be constructed from half round material bent into proper shape to form a cylindrical pin. suitable head 18 is formed on the pin 0 posite the shoulders 19 heretofore mentioned.
It will be understood that a pin constructed as described may be inserted in the alined openings in a hinge member and journal box by pressing the resilient arms 16 together, the tapered ends of said arms facilitating such insertion. After the pin has been inserted through said openings it will be further understood that the arms 16 will be forced apart by the spring of the metal and that the shoulders 19 on the end of the arms will engage the outer wall of the hinge member 12 and thus prevent withdrawal of the pin in one direction, the head 18 of the pin preventing its withdrawal in the opposite direction. The distance between the head 18 and shoulders 19 is only slightly greater than the combined length of the openings through which the pin is inserted and the head and shoulders thus serve to restrict movement of the pin in such openings.
It will be apparent that hinge pins of the character here described may be easily and quickly applied, that the use of fastening keys is unnecessary, and that loss of the pins with consequent loss of the lids and injury of the journals from dust and dirt is avoided. Furthermore, the spring action of the arms causes the outer Surfaces thereof to closely engage the openings in which the pins are mounted thus preventing noise and rattling and wear of the parts, common in the old forms of construction.
Having thus described the invention what I claim as new and desire to secure by Letters Patent is:
and a lid therefor having alined cylindrical openings, of a hinge pin for pivotally securing the lid to the box, said pin comprising two parallel resilient arms rigidly secured together atone end and arranged in said openings, each of said arms being curved on its outer surface to fit the walls of said openings and each yieldingly engaging with said walls, said pin having a head at one end and one of said arms having a shoulder on its outer surface near the free end thereof whereby longitudinal movement of said pin in said openings is restricted.
3. The combination with a journal box and a lid therefor having alined cylindrical openings, of a hinge pin for pivotally securing the lid to the box, said pin comprising two parallel spaced resilient arms rigidly secured together at one end and arranged in said openings, each of said arms being curved on its outer surface to fit the walls of said openings and each yieldingly engaging with said walls, each of said arms at its free end being provided with a shoulder and a head on the opposite end of the pin whereby longitudinal movement of said pin in said openings is restricted.
1. The combination with a journal box and a lid therefor having alined cylindrical openings, of a hinge pin for pivotally securing the lid to the box, said pin comprising two parallel spaced resilient arms integrally connected at one end and arranged in said openings, each of said arms being curved on its outer surface to fit the walls of said openings and each yieldingly engaging said walls, each of said arms at its free end being beveled and provided with a shoulder and a head on the opposite end of said pin, said head andshoulders serving to restrict longitudinal movement of said pin in said openm s.
The combination with a journal box and lid therefor having alined cylindrical openings, of a hinge pin for pivotally securing the lid to the box, said pin comprising a cylindrical bar split longitudinally to form two spaced resilient arms integrally connected at one end, said arms being arranged in said openings and having their outer surfaces yieldingly engaging said walls, each of said arms at its free end being provided with a shoulder and a head on the opposite end of said pin, said head and shoulders serving to in said openings.
In testimony whereof I afiix my signature.
