LOCOMOTIVE DRIVING MECHANISM.

Application filed January Mv invention relates to certain improvements in locomotives of the rack and pinion type. in which the rack mechanism is located between the main driving-wheels.

The invention is particularly adapted for use on narrow-gauge locomotives, where the space is limited.

The object of the invention is to so arrange the main rod and the side rods of the rack engine that the main rod will be directly above the side rods, thus allowing the rack mechanism to occupy a narrow space.

In the accompanying drawings:

Fig. 1 is a side view of a locomotive, showing the. main driving-wheels and frame, as well as a portion of the boiler, in dotted lines, and the rack mechanism in full lines;

Fig. 2 is a plan view illustrating one-half of the mechanisn'i;

Fig. 3 is a detached view of the main rod; and

Fig. rods.

1 is the main frame of a locomotive. 2 is the main axles having the drivingwheels 3 and the usual cranks (not shown). The boiler-t is supported on the main frame 1 in the usual manner. The frame of the rack mechanism is carried by the main axles 2 2. as shown.

Mounted in boxes in the frame 10 are axles on which are secured the pinions (3 which engage the racks on the road-bed of the track. The cranks 7 are secured to or form part of the axles.

Mounted on the wrist-pins 9-9 of the cranks is a side rod 8. The wrist-pin 9 is adapted to an adjustable box 11. which is made in two parts as shown, and back of 'one of the parts is a wedge 12, being capable of adjustment by a bolt 12 Extending upwardly from the side rod 8 is a bearing 13 having: a bushing 14 in the present instance. and extending through this hearing is a pin 15, which connects the main rod 16 with the side rod. This main rod is forked to extend on each side of the bearing 13, as shown in Fig. 2, and is directly above the side rod, so that space is economized, and the two rods are so formed that they will not interfere.

The main rod is coupled by a. pin 17 to a.

cross-head 18, which is adapted to slide on the guide 19. Attached to the cross-head is a piston-rod 20 leading to the piston in the cylinder of the rack mechanism of the locomotive.

The bearing 21 of the main rod is made in the form of a split-box, and is adjusted by means of a wedge 22 or other device. The bearing 23 at the opposite end of the rod 16 has a cylindrical bushing, through which extends the pin 15. It will be understood that the mechanism is duplicated on the other half of the locomotive.

The details of the rods 8 and 16 may be modified without departing from the scope of the invention. which is to so design the rods that the main rods will be located di rectly above the side rods.

By this arrangement, the only rack mechanism between the frames of the rack mechanism are the pinions which are mounted 011 the axles 5. The main rod and side rods are located between the rack frame 10 and the main driving-wheels 3 of the locomotive.

I claim:

1. The combination in a locomotive of the rack type, of rack mechanism including crank-axles and pinions mounted on said axles; side rods; and main rods, said side rods being coupled to the cranks of the axles, and the main rods being pivoted to the side rods and located directly above the side rods, the end of each main rod being connected to a cross-head of the locomotive.

2. The combination in a locomotive of the rack type, of a rack frame; two axles mounted on the frame; pinions mounted on the axles between the frame; cranks on the axles, outside of the frame; a side rod connecting the two parts: an upwardly extending bearing on the side rod; a main rod located directly above the side rod and pivotally connected to said bearing of the side rod; and a cross-head to which the main rod is pivotally connected.

3. The combination of the main frame of a locomotive; main axles; driving-wheels and cranks thereon; a rack frame mounted on the main axles between the drivingwheels; two axles on the rack frame; cranks on said axles; pinions on the axles; a side lit) rod on each side of the rack frame and connecting the cranks of the rack axles; and a main rod mounted above each side rod and connected to the side rod at one end.

4. The combination in a locomotive of the rack type, of a rack frame; tWo axles mounted on the frame; pinions on the axles; cranks on the axles, outside of the frame; 9.

side rod having a bearing at each end, one of said bearings being adjustable, said rod having an upwardly extending bearing near one end; and a main rod located above the side rod and connected to the upwardly extending bearing of said side rod.
