ADJUSTABLE SWITCH BLOCK Filed Deo. 2l, 1928 Il, I Y Z//vv NTD/1? M W/'r/VESS Y 4 M r E v 77.1.75'r EYE Patented Sept. 20, 1932 UNITED s'rA'rEs PATENT OFFICE y, LEWIS H. HASSELfOF UTICA, NEW YORK, ASSIGrNORy TO SIGNAL ACCESSORIES COR- PORATION, F UTICA, NEW YORK, A CORPORATION OF NEW YORK ADJUSTABLE SWITCH BLOCK Application led December 21, 1928.V Serial No. Y327,672.
This invention relates to an adjustable switch block adapted to be used in connection with railway switches for holding the switch point in its open position in case the switch operating means or any part thereof should be temporarily impaired or otherwise rendered unsafe in its operation.
The switch is usually operated by a bar or similar device attached thereto by one or more bolts extending entirely through the point of the switch and operating bar and one of the objects of the present invent-ion is to provide a switch block capable of being easily and quickly installed in operative position between the rail and point of the switch for positively holding the switch in its open position until the opening means can be repaired.
Another object is to enable the switch block to be adjusted to conform to the throw of different switch points or to different distances between the switch and rail when the switch point is in its full open position.v
Other objects and uses relating to specilic parts of the device will be brought out in the following description.
In the drawing:
Figure l is a perspective view of a portion of a switch and adjacent portion of its operating means, together with the adjacent rail of the track with which the switch point is adapted to cooperate andmyimprovedswitch block in operative position for holding the switch open.
Figure 2 is an enlarged sectional view of the adjustable switch block, the dotted lines indicating portions of the rail and switch point.
Figure 3 is an end face view of the head end of the adjusting bolt of the switch block.
In order that the invention may be clearly understood I have shown a portion of a track rail A and the point of a switch B associated therewith to be moved from its closed position to its open position and vice versa by any suitable operating means including a shifting bar C- which is secured to the switch point by one or more bolts c, Figure l.
These bolts extend through registering openings in the switch B and operating member C so ythat theirheads engage the inner face of the switch point while the nuts are preferably at the outer side of the switch point for convenience of adjustment.
' The rail A may be secured to the'usual ties D in. any suitable manner as, for example, by the conventional spikes d. The adjustable switch block forming the :subject matter of the present invention is adapted to be placed between the adjacent faces of the rail A and switch point B so that one end thereof may engage the web of the rail between the top flange and lower flange while the other end is adapted to engage the'inner face of the switch point B preferably in line with one of the bolts c by 'which the operating member C is securedto the switch.
As illustrated, this switch block comprises a tubular member l, a bolt 2 and a lock nut 3, the tubular member 1 being threaded internally for receiving the 'threaded end of the bolt 2 and permitting the latter to be adjusted according to the distance between the web of the rail and inner face of the switch when the latter is fully open. 4
The outer end of the tubular member -lis provided with a socket tfor receiving the head, as of of one of the bolts c, the socketed end of the tubular member l being adapted' to engage the inner face of the switch B around the head of the adjacent bolt c while the other end is angular in cross section tobe engagedby a suitablewrench by which it may be turned for varying the length ofthe block. u
This peripheral engagement of the socketed end of the tubular member l with the head of one of the bolts c serves to hold the adjacent end of the switch block in operative position against lateral movement.
The outer end of the bolt 2- is enlarged to form a head 2 of sufficientvertical height to allow its lower and upper edges to engage respectively the upper side of the base flange of the rail A and underside of the top or ball of the rail and also to engage the adj acent face of the webvof the rail thereby holding the corresponding end of the switch block against vertical movement relatively to the m0 rail when adjusted for use.
formed with relatively Hat lateral extensions 6 provided with perforations 7 Vby which the entire device may be hung upon a hool, nail or other suitable support when not 1n use. i c
Operation When the switch-operating means is broken or impaired and it is desired to use the switchiblock for holding the switch in its open positiomsaid switch block is first shortened'byproper adjustment of the parts -1 and '-Sf relatively tothe bolt 2 and is then placed between the adjacent faces of the rail A and switch member vB with the socketed endof the tubular member 1 engag. ingthe inner face of the switch member B around the head of the adjacent bolt c whereupon the member 1 may be turned upon the threaded portion of the member --2-- to force the head 2 of the bolt into engagement with the adjacent face ofthe web of the rail A and when the parts are extended sufficiently to force the switch member to its open position, the lock nut 3 may be tightened to hold the parts 1 and 2 in said extended positions with the switch open.
When the switch block is placed in operative position in the manner described it will be in a plane a sufficient distance below the top of the wheel to clear the flange of the wheels of the rolling stock and at the same time will be held in this position by the my hand this 13th day of December 1928.
