Specification of Letters Patent. l Patented April 14, 1908. Appiicacionied July a, 1907. serial No. 382,024.
. To all whom it may concern: l
e it known that I, CHARLES H. WILLIAMS, Jr., a citizen of the United States, residing at- `In the drawings, l indicates the brake head j having the 'aws laand the usual lugs usual j f 1l. In the cons ruction shown 1n Fig. 2
a j n a n y Chicago, Cook county, Illinois, have inventedn strengthening webs 2 integral with the brake' a certain.new and useful Improvement in Brake-Heads, of which the following is a full, clear, and exact description, such as will enable others skilledV in the art to which it appertains to make and use the saine, refer--l ence being had to tlieaccoinpanying drawings, forming part of this speciiication, 4in which- Figure l is a detail view brake head; and Fig. 2 is a modified form of brake head. This invention relates to a new and useful improvement in brake heads, the object being to provide a brake head with a strengthen-f ing rib or web across .what might be termed the throat portion of the brake head located between the two jaws.
The brake head shown in the accompanying drawings is what is known as the Christie head, the jaws and lugs conforming to the teinplet re uireinents as prescribed by the Master Car uildersAssociation. Brake j head extend between the lugs 1b, while in Fig. l these strengthening webs aiecontinued between the lugs and the jaw members of the brake head so as to provide a continuous of my improved similar View of a o'f the brake head said anges could project laterally from the side faces of the brake head so as to strengthen the throat portion, but as it is desirable to preserve the sidelines, I prefer the arrangement shown in the drawings. Having thus described the invention, what is claimed as new and desired to be-secured byLetters Patent is:
1'. A brake head provided on its front face with apair of key lugs, and reinforcing'webs connecting said lugs together; substantially as described; 2. A brake head provided adjacent its ends with jaws, keylugs located intermediate said 'aws, and reinforcing webs connecting said ey lugs together; substantially as described. 3. A'brake head provided at its opposite ends with jaws, a pair of key lugs located inin present use are usually made of malleable iron, and in practice it has been determined that either from improper mounting of the brake shoe in the head or improper setting of the brake head on the beam, the jaws of the brake head are subjected to unusual strains which has developed al weakness inA that part of the brakev head indicated at A, which I have designated as the throat or connecting portion between the jaws.
Because the brake heads are made of malleable iron it is im racticabel in practice to increase the thic ness of the metal at the throat portion, due to the liability of the Inalleableized casting to crack, which cracking results from uneven shrinkage. Therefore, I pro ose to provide a strengthening web inthe brake head, which strengthweb may eitherextend between the key ugs or may continue beyond the key` lugs to be lconnected to the jaws.
My invention consists in providing a brake head with a strengthening web or webs whose function is to reinforce the throat pori said lugs being spaced away from each other, tion of the brake head so that said brake and reinforcing webs bridging the space behead can withstand heavy strains imposed .tween said lugs; substantially as described.
- v6. A cast metal brake head comprising a connecting theV lugs together and also connecting the lugs and jaws together substantially as described. y
4.'A cast metal brake head comprising a. body portion provided adjacent its opposite ends with jaws, key lugs arranged intermediate said jaws, and reinforcing webs formed 4integral with the body portionand bridging the space between said lugs; substantially as described.
5. `A cast metal brake head having a concaved front face provided with a pair of integral lugs of approximately inverted U-shape,
ianges project forwardly from the front faceV reinforcement on.each side of the face of the termediate said jaws, and reinforcing webs A body portion provided at its opposite en ds In testimony whereof I hereunto eix my with jaws, a pau' of lugs of approximately msignature inl :Lne presence of two wltnesses7 Verted U-shape on said body portion. inter-Y this 26 day of June 1907 mediate the jaws, and reinforcing webs con- CHARLES H. WlLLIAMS, J R. meeting the lugs together and also connecting Witnesses:
the lugs and jaws together; substantially as i E. B. LEIGH,
described. E. T. WALKER.
