DOUBLE-DECKED VEHICLE.

Specification of Letters Patent.

Patented Dec. 30, 1913.

Application filed May 21, 1913. Serial No. 769,030.

To all whom it may concern:

Be it known that I, LUnw1c SPANGLER, a subject of the Emperor of Austria-I-Iungary, residing at Vienna, Empire of Austria-Hungary, have invented certain new and useful Improvements in Double-Decked Vehicles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to double decked vehicles more particularly tram cars and rail- Way cars running on lines with numerous stations closely following each other at each of which many passengers enter and leave the car. The total height of such cars must not in the first instance exceed a certain limit, and further provision must be made for permitting the passengers to enter and leave the car and to reach the upper deck from the lower deck and vice versa rapidly and with out interfering with each other. For this purpose I employ the well known construction in which the floor of the lower deck is located as low as possible between the axles or trucks and the entrance and exit door or doors are located in the lower deck between the axles or trucks. Further I arrange in the lower deck longitudinal benches at the sides of the vehicles with a longitudinal passage way between such benches leading on the one hand to a vestibule in front of the entrance and exit door or doors and on the other hand to the stairs leading from the lower deck to the upper deck and arranged above the axles or trucks.

My invention consists in the particular construction of the upper deck and in the particular arrangement of the benches in the same as hereinafter fully explained and claimed with reference to the annexed drawings in which Figure l is a side elevation of a tram car embodying my invention. Fig. 2 is a plan of the lower deck. Fig. 3 is a plan of the upper deck and Fig. 4: is a transverse section of the same.

The entrance and exit door or doors 2 are arranged between the trucks ,3, i and the stairs 1 leading from the lower deck to the upper one are arranged above the trucks.

The benches 5 of the lower deck are arranged lengthwise with their backs at the sides of the car with a central longitudinal passage way between them which leads from the vestibules provided in the lower deck in front of the entrance and exit door or doors 2 to the stairs. In the upper deck there are provided above the vestibule benches 9 arranged lengthwise at the side walls of the car with a passage way 10 between them. Between the benches 9 and the stairs l lengthwise benches 6 are provided with their backs opposing each other, longitudinal passage ways 7 being left at both sides of this double bench. These passage ways 7 communicate with the central passage way 10 by spaces left between the benches 9 and 6. Each of the stairs 1 leads into one of the lateral passage ways 7. The floor of the upper deck is cut away or suitably raised below the benches 6 in the well known manner whereby the clear height of the central passage way of the lower deck is increased. The central portion of the upper deck might be provided with transverse benches or a single central longitudinal bench below which latter the floor of the upper deck might be raised the same as below the double bench 6.

In the central portion of the car the re quired clear height of the longitudinal passage way of the lower deck is secured by the fact that in this portion the floor of the lower deck is drawn down between the trucks as shown. A step 8 is provided between the central portion and the end portions of the floor of the lower deck as owing to the trucks the latter must be on a higher level than the former.

For reaching the upper deck the passengers entering the vestibule in the lower deck go through the central passage way of the same to one of the stairs 1 (for instance the front one) and over the same to the corresponding lateral passage way 7 of the upper deck to the desired seats. The passengers leaving the car may go down the other stair (for instance the rear one) which they reach through the corresponding lateral passage way 7. In order to enable the passengers to go these ways without interfering with each other the passage ways 7 of the upper deck must be of suflicient width which may be realized by making the upper deck of the car more wide than its lower deck. Now the width of the car must not exceed a predetermined limit as in the case of double track two cars could not pass simultaneously a curve in opposite directions. Therefore I make the width of the upper deck smaller in the central portion of the car than at its ends. This is attained without affecting the free passage of the passengers within the car by arranging the benches 9 in the central part of the upper deck at the walls of the car where the central passage way 10 is just as wide as the central passage way of the lower deck and quite suflicient for the free passage of the pas-e sengers while at the ends the required width of the. lateral passage ways 7 is obtained by increasing the width of the upper deck of the ear.

If the stairs are two fiighted as shown, the floor of the upper deck must be cut away over the bottom flight as shown. One half of the central bench must be correspondingly shorter or it must be bent at right angles as illustrated. But the stairs might be straight and arranged transversely to the car and provided with separate entering and exit doors and outer steps leading thereto. Thereby the space available for seats is increased and the entrance and exit doors for the two decks are separated from each other. The stairs I might also be so arranged that both lateral passage ways 7 and the seats on the double benches 6 are freely accessible directly from the stairs, whereas as shown in the drawings one-half of each of the double benches 6 is accessible only from the center of the upper deck and hence it is suflicient to make only one of the lateral passage ways 7 at each end of the upper deck wide enough for a free passage to the stairs. This may be realized in the arrangement above described at the ends of the car by suitably increasing the width of the upper deck and at the central portion by substituting for the double bench a single central bench as above indicated, thereby providing lateral passage ways. In order to facilitate the communication between the lateral passage ways 7 and the central passage way 10 notwithstanding the reduced width of the upper deck in its central portion I may locate at the end of the longitudinal double benches 6 a transverse bench 6 below which the floor of the upper deck is cut away. I thereby prevent the communication between the inner ends of the passage ways 7 and the central. passage way 10 from being impeded by the feet of the passengers at the inner end of the bench 6.

What claimed is 1. In a double decked vehicle the combination of wheels supporting the ends of the vehicle, a lower deck and an upper deck, the

gitudinal double benches with their backs opposing each other in the end portions of the upper deck, lateral longitudinal passage ways on both sides of such double benches, such lateral passage ways communicating with the central passage way of the upper deck and at least one of such lateral passage ways communicating with the stairs, the width of the upper deck being greater at the said end portions than at its central portion, and the floor of the upper deck being cut away under the said double benches.

3. In a double decked vehicle the combination of a lower deck and an upper deck, longitudinal benches at the sides of the vehicle in the lower deck, a longitudinal passage way between such longitudinal benches, stairs from the lower deck to the upper deck beginning at the ends of such passage way, benches in the central portion of the upper deck, a longitudinal passage way between the last named benches, longitudinal double benches with their backs opposing each other in the end portions of the upper deck, trans verse benches at the inner ends of such double benches, the length of such transverse benches being substantially equal to the width of the double benches, lateral longitudinal passage ways on both sides of such double benches and transverse benches, such lateral passage ways communicating with the central passage way of the upper deck and at least one of such lateral passage ways communicating with the stairs, the width of portions, and the floor of the upper deck being cut away under the said double benches and transverse benches.

In testimony whereof, I atiiX my signa- ARTHUR GAUMANN, AUGUST .FUeena.
