BRAKE-BEAM.
SPECIFICATION forming part of Letters Patent No. 636,755, dated November 14, 1899.
' A li ation filed November 22, 1898. Serial No. 697,163. (No model.)
To all whom, it may cmwerze;
Be it known that I, THOMAS E. CARLISS, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Brake-Beams, of which the followingisaspecification,reference being bad therein to the accompanying drawings.
The invention consists in the construction of a brake-beam and in the construction, arrangement, and combination of the various parts, whereby a strong light beam is made with a minimum of labor and at a low cost, all as more fully hereinafter described.
In the drawings, Figure 1 is a sectional plan View of the beam. Fig. 2 is a cross-section centrally through the fulcrum-block. Fig. 3 is a side elevation of a portion of the beam, showing the support for the wheel-guard finger and safety-chain connection. Fig. 4 is a perspective View of the fulcrum-block detached. Fig. 5 is a section on line co m, Fig. 1, looking toward the fulcrum-yoke. Fig. 6 is a section on line y y, Fig. 5. Fig. 7 is a section on line 2 2', Fig. 1. Fig. 8 is a plan View of the brake-beam.
The beam I make of two plates A, substantially fiat, but preferably corrugated longitudinally or of wavy cross-section, as shown in the drawings. This stitfens the beam somewhat against vertical strains. These plates are sufficiently wide to enable me to dispense with a truss-rod. The two plates are separated at the middle by a block B, which preferably has the marginal flanges a, with which the edges of the plates engage. Suitable rivets Z), passing through the plates and block, serve to secure these parts together. On its outer face the block is provided with the circular flange c, with entering-slots d and stops 6, as shown in Figs. 4 and 5.
O is a fulcrum-yoke having hooks Z adapted to be engaged with the slots 01 and then partially turned to lock beneath the flange c. The stops 6 determine the angle at which the yoke should stand to receive its lever for either right or left hand beam. To hold the yoke detachably to the block,I place the headed clamping-bolt D through the block and yoke, and suitable nuts on the rear of the block cause the head of the bolt to'clamp the yoke firmly in position.
E are the brake-heads. They are provided with apertures or sockets of a shape corresponding to the cross-section of the plates, in which the ends of the plates engage. The brake-head thus serves to space apart the ends of the plates, these parts being secured together by suitable rivets or bolts F.
G are spacing blocks or plates. H are other spacing-blocks near the brake-heads which are provided with the transverse and vertical apertures 11 70. These apertures intersect at one side. Through the vertical aperture passes the eyebolt T, its eye serving as a connection for the safety-chains, while the bolt serves to clamp the parts together and to hold in the wheel-guard finger J, which passes through the transverse aperture and is notched at the intersecting point of the bolt T.
A beam thus constructed is Very readily assembled, as all that is required is to take the plates, which may be rolled into proper shape at the mill, and engage them with the brakeheads and central block, insert the intermediate blocks, and then rivet. The fulcrumyoke may then be placed on and clamped by its securing-bolt and the wheel-guards clamped by their eyebolts.
It is evident that in case of breakage or wear of the fulcrum-yoke a new one may be placed in position by simply withdrawing the clamping-bolt and renewing the yoke alone.
What I claim as my invention is- 1. A brake-beam formed of two independent straight substantially fiat plates, brakeheads having separated bearings conforming to the size and shape of the end portions of the plates in which the ends of the plates engage and are secured and a central block secured to and between the plates.
2. A brake-beam, formed of two straight independent plates havinglongitudinal corru= gations, brake-heads having separated sockets or bearings corresponding to the crosssection of the plates and in which the ends of the plates are engaged and secured, a block between the middle portion of the plates tying them together and spacing them apart,
and a fulcrum-yoke connected to said block.
3. A brake-beam comprising two flat plates, brake-heads secured to the ends, an integral spacing-block centrally between the plates and horizontal overhanging flanges on the top IOC- and bottom edges of the block with which the edges of the plates engage, to hold the plates from separating.
4. In a brake-beam composed of two plates brake-heads at the end thereof, a central block between the plates, a flanged socket at the outer end of the block having entering-apertures, and a fulcrum-yoke having hooks adapted to engage said socket, and be locked by a partial rotation.
5. In a brake-beam, a central block, an overhanging circular flange on its outer face having entering-slots, a fulcrum-yoke having hooks adapted to engage behind the flange and a bolt passing through the yoke and block, its head clamping the yoke to the block.
6. In a brake-beam, the combination of the plates, the central block having a circular flange on its outer face, with entering-slots, a fulcrum-yoke having hooks adapted to engage the slots and lock beneath the flange, and stops for the hooks, to determine the angle for setting the yoke.
7. In a brake-beam, the combination of two separated plates, the brake-heads secured to the ends, the central block or blocks between the plates near the brake-heads having vertical and transverse apertures partially intersectin g, an eyebolt passing through the plates and the vertical aperture, and a fingerguard passing through the transverse aperture, the finger-guard having a notch cut at the point of intersection of the bolt, substantially as and for the purpose described.
8. In a brake-beam, the combination of two separated plates connected to the brake-heads, of blocks between said plates near each brakehead having a horizontal aperture, a fingerguard therein, a vertical aperture through the block at the point which will intersect a portion of the finger-guard, a notch at said point of intersection, and an eyebolt passing through the plates and the vertical aperture and engaging the notch, the eye of the bolt forming the safety-chain connection.
In testimony whereof I affix my signature in presence of two witnesses.
THOMAS E. CARLISS.
