Description

In patent number 18345 described double

 g6uennpticheskaya spring for carts ,,

and which cage bottom half springs

middle with a clip of the upper half-springs by means of bolts, nuts of which,

so that the x regulation is resolved

/ p skluressomi, simultaneously rotate from the corresponding transmission.

; proposed modification of a double loulahiptic spring for the purpose of 4 adjusting the distance between

upper and lower olousors, vertical screws, instead of nuts, vertical screws,

& Sch in the fixed nuts, screw with the upper half of the springs. .

 In FIG. 1 depicts the view

On the side of the part of the frame of the wagon with a proposal of a spring &spring; FIG. 2-side view with cha, putaway cut from the footboard

SHIPPING to the roller, which regulates the distance between the no-stressors; FIG. 3-

tr on the other side of the wagon; FIG. four-

 along the JB lines in FIG. one; fig 4-

 according to CD in FIG. four; FIG. 5 - vertical section through the transfer gear box; l FIG. 6 is a vertical section view of the distance by half springs.

The clips 5 of the semi-elliptical spring of the wagon (Figs. 1, 4) are connected by Viits 35 so that their heads are placed in the lower holder and the screwed rods fit into the fortified at the top. nut cage, with screws 35j in col-. l x of simultaneous turning, the days of increasing or decreasing the distance between the semi-springs, you have a chain. The rotation of the screws 35 is made by auto-. mathematically by lowering the basement 4 or 16 when passengers enter or start the carriage. The footboards are the shoulders of the doorways around the bottom-fortified frames, carts, axes 37 (Fig. 2) of the levers, the other shoulders 15 of which are hingedly attached to the vertical rods mi 13, which, when moving, the worm through the spring dogs 10 and the ratchet wheels 7 enclosed in the boxes JJ and F (Figs 1, 2, 3), mounted on the side of the frame:; wagons in bearings 1 and reporting, in their

alternately, via gear through gear 31, 32 to shaft 36. The latter, through a bevel gear 33, 34, informs the rotation of the rod 19 connected by the cardan 28 (Fig. 4) with one of the screws 35., Ratchets 10, 7 the boxes E and I (figs. 1, 2) act in different directions, i.e. if, during the lowering of the step 4, the shaft 30 is rotated in one direction, then during the lowering of the step 16 it will turn in the opposite direction. A safety board 17 (Fig. 2) is attached to the footboards at the bottom to prevent the passenger's foot from getting in between the footboard and the board of the stopper 38. The footboards are held horizontally by the springs 12.

To manually change the distance between the half-springs, there is a handle 24 (Fig. 5) connected through a bevel gear 20, 21 enclosed in the box 23 (Fig. 1 and b) with a rod 19. The distance between the half-springs is shown by a dial mechanism 27 ( Fig. 1 and 6), the movement of the arrow 26 of which is associated with the rotation of the rod 19 through the worm gear 25, 18.

The subject of the patent.

.one. Modification of a double semi-elliptical spring for wagons according to patent No. 18345, differs in that the distance between the upper and the lower position of the upper and lower straight wheels is adjusted. Instead of simultaneously rotated bogged nuts, the vertical screws 35 (Fig. 1 and 4) rotated and in the fixed, fastened with the upper spring compressor, / nuts.

2. The form of the device described in paragraph 1, characterized in that for the automatic actuation of the passengers entering or entering the carriage of the mechanism that changes the distance between the half-springs, vertically pivoting levers and shoulders 16 are used (Fig. 1 and 2) which serve as footboards for wagons, and the others are 15 s, h), with vertical rods 13 (Fig. 2 3), which, when moved, by means of ratchet gears, horizontal shaft 30 mounted along the wagon and, equipped according etstvennymi gears to rotate vertically: th rod 19 (Figures 1 and 4.) associated with the screw 35 spring. , 3, With the device described in p. 1 and 2, the use of an auxiliary device is for driving by hand from inside the carriage of a mechanism that changes the distance between the half springs, consisting of a handle 24 connected to the rod 19 by means of a bevel gear 21 and 20 (Fig. 5).

4. With the device described in p. 1, 2 and 3 the use of a dial pointing mechanism with an arrow 26 (Fig. 6), the movement of which is connected by means of a worm gear 25 and 18 with the rotation of the screw 35 and the handle 24..V E to the additional patent P.N. 18084 A. Orlovsky
