Application filed June 24, 1926. Serial No. 331,469.

To all wiwm it may concern:

Be it known that I, CHARLES Evsm'rr SWEEm-n?, of the town of Osborne, in the Province of hianitoba, Canada, have invented certain new and useful improvements in Storageins, of which the following is the specification..

The invention relates to improvements in storage bins for domestic use and particularly to an improvement in the storage bin previously 4filed by me and fully shown and described in an application No. 302,798 iled the 9th of June, 1919, and the object of the present invention is to provide a means for positively guiding' the bin carrying roller and preventing the same from end or side shifting'when in use, said means being furher utilized to stop the out-pulling of the With the above object in view the invention consists essentially in a bin, a Vcasing receiving the bin, a roller interposed between the bottom. of the casing and the bottom of the bin, pinions located at the ends of the roller and racks for the pinions secured to the bottoms of the casingr and bin, the parts being arranged andV constructedas hereinaftermore particularly described and later pointed out in the appended claims, reference beingy hadto the accompanying draw.- ing in Which:-

Figure 1 is a sectional view through the casing and showing the binin the inner position. 1

Fig. 5 is a perspective view of one end of they roller.

In the drawing' like characters of reference indicate corresponding parts in the several figures. r

1 is a stationary casing' of any suitable design'providing; the bin compartment 2 entered through the open end 3 of the casing'. 4 is the bin designed to bey stored Within the casingand having' the ends thereofclear of they side walls of the casing and of such a height that there is a clearance space reserved both above and below the inserted bin. AV catch 5 is provided for opening' and closing purposes and the front of the bin is extended as indicated at 6 and 7 to limit the in ward travel and Aform a close Contact between the front of the bin and retaining casini'. The rear upper corners of the bin are'cut away as indicated at 8 to allow it to swing to the open position without striking the top of the casing' and a chain 9 is supplied to prevent the bin from upsetting and pulling entirely away from the casing when the same is opened.

I have not entered into a detailed description of the aforesaid parts as they are the same as described in my prior application above mentioned.

The inserted bin rides on a forward roller 10 which is slightly shorter than the full width of the bin bottom and it is supported rearwardly by a trailing foot piece 11 permanently attached to the bottom of the bin at the back. To each end of the roller attach in any suitable Way a pinion 12, the teeth of which project beyond the circumference of the roller.

In the present instance the pinions are each mounted on a square end spindle 13 driven 'into the end of the roller and tted with a fastening nut 14 and washer 15 permanently holding the pinion in place.

The teeth of the pinions are designed to ridenon upper and lower pairs of racks 16 and 17 countersunk in the bottoms of the bin and the casing and passing in a direction from they front to the back. ln actual practice the pinions. are not designed to carry the weight of the bin, this being carried by the roller, but simply act in conjunction With the racks as guides for the roller.

lt will be obviously necessary'when placing the racks to see that the teeth openings 18 therein are properly alined so that when the roller is put in position the pinions will operate on the racks and maintain the roller at all times in a true position at right angles to the direction of travel ofv the bin.

Once the parts are assembled it will be seen that the roller cannot end shift as the teeth engaging with theends of the teeth openings 18 Will not permit of' any such movement and further one end of the roller cannot get ahead of the otheras the ends of the roller will both advance at. the same time owing to the rack and pinion arrangement.

The front ends 19 of the bottom racks and the rear ends 20 of the upper racks form a positive vstop for the bin when rolling outwardly as it will be obvious that when the pinions reach the vfront position of their travel they would have to climb out of the rack openings 18 and in so doin@ would have to bodily ne, the fun weight 0i the bin and contents.

One can positively prevent any such 0ecurrence by making the clearance space betiveen the top ofthe bin and the top of the casing, such that a small raising of the bin will effect the jamming of the bin against the top of the casing and this before the pinions can ride out of the rack openings.

The operation of this bin is the same as in my prior application asl it simply rolls out on the roller in the same manner as before. The important feature of the present 'torn of the casing and constituting a traveling support for the bin, of pin'ions associated with the roller and racks for the pinions associated with the bottoms of the casing and bin and designed to maintain the roller at all times in a position at right angles to the` direction of travel of the bin.

3. The combination with a receiving carsing, a pullout bin normally contained Within the casing and a carrying roller interposed between the bottom of the bin and the bottom of the casing, of pinionsY secured to the ends of the roller, an upper and lower pair of racks secured to the bottom of the bin and the bottoni of the casing and engaging each pinion and positioned in conjunction with the pinions to positively guide the roller, the Weight of the bin being carried yupon the roller.
