ARTHUR H. JOHNSON, OF JERSEY CITY, NEXV JERSEY.
lNTERLOCKENG DEVICE FOR RAILWAY SVVITGHES AND SIGNALS.
SPECIFICATION forming part of Letters Patent No. 392,734, dated November 13, 1888.
Application filed August 17, 1888. Serial No. 233.016. (No model.)
To all whom if; may concern:
Be it known that I, ARTHUR H. JOHNSON, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and useful Improvement in Mechanism for Interlocking Railway Switches and Signals,ofwhioh the following is a specification, reference being had to the accompanying drawings.
This invention relates to that form of interlocking between switch and signal levers known as special looking or conditional. This form of locking difi'ers from the ordinary locking, inasmuch as the looking or releasing of one lever or levers by another lever or 1e vers is conditional upon the position of athird or other lever or levers.
Figurel is a plan of a very simple example of a system of interlocking tappets and locks illustrating my invention. Fig. 2 represents a section at right angles to Fig. 1 in the line 00 00. Fig. 3 is a face view, and Fig. 4 a side View, of one of the tappets and its appurtenances illustrating a modification of my invention. Fig. 5 is a face view, and Fig. 6 a side view, of a tappet illustrating another modification Fig. 7 is a face view of one of the slides or sliding sections of a tappet illustrating another modification.
Similar letters of reference designate corresponding partsin all the figures.
A A A A Fig. 1., designate four tappets, which-except that A A are fitted with transverse slides or sliding sections B 13 B B"are like those in common use in interlocking apparatus. The said tappets are represented arranged parallel with each other and fitted between projections 01' guides c c on a bed plate, O, in the usual manner, and are intended to be connected in the usual manner at (Z (Z with the operating-levers.
D D D D D D designate miter dogs or looks such as are commonly employed in interlocking apparatus, arranged to slide between the projections or guidesc c of the plate 0 in a direction transverse to the movement of the tappcts for the purpose of engaging with or disengaging from the lit-shaped notches a a or b b in the tappets. The notches a a (shown in the tappets A A) are like those in tappets commonly used.
The slides or sliding tappet-sections B B 13 13 are what constitute the principal feature of like the notches are, correspond in form with k the ends of the miter dogs or looks, the number of said notches being according to the particular special locking to be performed. These slides or sliding sections are fitted to trans verse slideways e c in their respective tappets. The parts of the tappets on which the sliding sections are applied within the slideways are represented as made narrower than the other parts. In the example shown in Figs. 1 and 2 the slideways c c are made within the tappets themselves and the sliding sections are fitted to them with rabbets. In the example shown in Figs. 3 and4= the slideways are formed by gibs bolted to the face of the tappet. In the example shown in Figs. 5 and. 6 the tappet consists of a narrow bar, f, having secured firmly to it by rivets or bolts pieces 9 g,which form the slideways c and the heads d. In the example shown in Fig. 7 the sliding section is shown constructed with two transverse slot-s, h, to slide on pins 2' in the tappet.
In Fig. 1 two examples of special locking are illustrated. In this figure the tappets are shown in their home position in full outline and in their reversed positions in dotted outline. In the first of these examples the tappet A locks A" back and front when A and A are both reversed, but not when either A or A is home. The sliding section B of the tappet A has a notch, 12, which is opposite the miter of the dog or lock D when A is in its home position. Now, it will be understood by reference to Fig. 1 that when the tappet A is reversed A will not be locked either back or front if both or eitherA" or A is in the position shown, because, although the miter at the left hand of the dog D will be made to coincide with one of the notches in the slide B the tappet A is free to be moved because of the side play allowed to the sliding sections B and 13 If, however, both the tappets A and A are reversed, then the dogs D and D will be made to abut with the sliding sections B and B as shown in dotted outline in Fig. 1, so that when A is reversed and the left-hand end of the dog D is made to coincide with either of the notches in the sliding section B the tappet A will be held in that position with its operating-lever in corresponding po- ICO sition because all side movement of D, b, and D is checked. In the other example the tappet A looks A only when A is over or reversed and A is home. If the tappet A", which is fitted with the sliding section B be reversed, and the tappet A carrying the slide B remain in its normal position, then D B" D B D will form or operate in combination with each other to form between the tappets A and A a continuous dog of such length that if the tappet A be reversed said continuous, or, as it may be termed, the combination, dog, will have its miter, which consists of the righthand extremity of D", forced out of the corresponding notch a in the tappet A and its miter formed by the left-hand extremity of D. forced into the corresponding notch a in the tappet A, thus securely holding the lastmentioned tappet in the normal or home position; but this locking of A by A is conditional upon A being reversed and A being home, as it will be readily seen that if the notch in either sliding section B" or B is opposite the dog D" or D then there is a sufiicient lost stroke in the combination-dog to 25 permit A to be reversed at the same time as A".
WVhen the intervolved tappets are not adjacent, as shown in Fig. 1, but remote from each other, I propose to employ the ordinary 3o connectingrods to transmit the action of one dog to another.
\Vhat I claim as niyinvention, and desire to secure by Letters Patent, is
The combination, with the tappets of an in- 5 terlocking switch or signal operating apparatus and dogs between the said tappets for, locking them together, of slides or sliding sections fitted to said tappets for operating said. dogs, substantially as herein described.
ARTHUR H. JOHNSON.
