Application fiiea July 23, 1916'. seriai No. 111,891.
v of Texas, have invented new and useful improvements in Door Operating and Locking Means, of which the following is a specificauo'n.
This invention relates to I an improved means for operating sliding doors, whereby the door may be moved to lock in any de sired position. V
A further object vof the" invention is to provide an ac-tuatiiig and locking means for sliding doors including arack that is connected to oneof the edges of the door and which is actuated by a toothed wheel that coeperates with a plurality of other toothed wheels, the hub of one of the toothed wheels-having arranged thereon a disk pro vided with a spring pressed handle having its head formed with teeth which are adapted to co-engage with teeth upon a circular rack, and means being provided for locking the handle when in engagement with the teeth of the circular rack to prevent the 1011- gitiidinal movement of the rack bar and consequent movement of the door, means being also provided for sustaining the handle at a right angle with relation to the disk to hold the said handle in operative position, and the teeth thereof out of engagement with the teeth, of the circular rack, whereby to permit of the actuation of 1 the toothed wheels and the sliding movement of the" door.
WVith the above and other objects in View the improvement} resides in the construction, combination and arrangement of parts set forth in the following specification and falling Within the scope of the appended claims.
In the drawings: Figure 1 is an elevation illustrating niy improvement upon the side of a car and showing the rack bar connected with the sliding door for the car, Fig. 2 is a greatly enlarged sectional viewapproxiinately on the line 2''.2- of Fig; 1, Fig. 3 is a similar enlarged sectional View approximately on the line 3-3 of Fig.1, Fig. 4 is a sectionel view approximately on the line of Fig. 1, Fig. 5 is a detail View lookingt'oward the outer face of the supporting or bed plate with the protective casing for the" gears removed as is also the toothed wheel having its hub provided with a disk,
Fig. 6 is a plan view of the underface of the disk, Fig; 7 is a sectional view illustrating the manner of retaining the handle in its open position, and Fig. 8 is a plan View of the disk, the lug and the end of the handle engaging with the lug being shown in sec- While in the drawings I have illustrated the improvement in applied position upon the side of the carto operate the door therefor, it is to be understood that the improvemerit is not to be thus restricted in its useful capacity as the same may be employed with efiiciency upon other devices having slidable doors.-
In the drawings,- the numeral 1 designates the side of an ordinary freight car, and 2 the door therefor.- My improvement contemplates the employment of a base or bed plate 3 which is secured in any desired inanher to the side of the car 1. Secured to the plate 3, at a suitable distance from the lower edge thereof is a circular toothed rack 4,
the same being substantially in the nature of a ring member whereby an axle 5 secured to the base or bed plate may extendcentrally. through the rack 4L. Arranged for rotation upon this axle is the hub 6 of a toothed wheel 7 and secured to or formed with the outer end' of the hub 6 is a flat disk 8' of a size to cover the circular rack 4, and
this disk may beprovi'ded with an annular depending flange 9' arranged around the circular tooth rack 4.
The disk 8 adjacent the peripheral edge thereof is provided with a substantially rectangular opening 10' and with a centrally disposed groove 11 which intersects the opening, the said groove 11 adjacent the end thereof opposite the" opening being centrally provided with a lug 12 having one or more transverse openings 13. The operating handle is indicated by the numeral 14 and includes enlarged end in the nature of a head 15 which is disposed in the opening 10 and which is pivotally secured to the side walls provided by the saidopenin'g, as indicated by the numeral 16. The outer end of the head 15, at the portion thereof through which the pivot 16' passes, is centrally bifurcated, whereby a spring 17 may be coiled around the central portion of the pivot to exert a pressure or tension between the disk and the head 15 of the handle to normally swing the handle to within the her, a spring pressed handle upon the disk normally resting upon the outer face of said disk, a slotted lug upon the disk, said handle having a notch to receive the lug and having its sides provided with openings registering with the slots in the lug, said handle having an enlarged end comprising a head member which is pivotally secured to the disk and which has one of its faces provided With teeth which normally engage with the teeth of the circular member,
spring means for normally sustaining the handle against the disk and the teeth thereof in engagement with the teeth of the circular member, a sliding lock upon the head of the handle, a keeper upon the disk to receive the said lock, and whereby the handle is retained at a right angle with relation to the disk, and a plurality of intermeshing toothed wheels one of which engages wlth 20 the teeth of the rack bar.
In testimony whereof I aflix my signature.
RICHARD J. FREEMAN.
