This invention relates to improvements in guides for the moving bodies in elevator and dumbwaiter systems. V a
In present day elevator and dumbwaiter installations, the car and counterweight are provided with guides extending the length of the hatchwa-y. These guides are usually constructed of steel channels orof T-rails and A feature of this invention is the provision of a guide'for a moving body in an elevator or dumbwaiter system thatissimple and that is readily and cheaply installed. To this end a continuous metallic tape is provided, which tape extends from the top to the bottom of the hatchway and is suitably secured therein;
This tape may be fastened at both ends under sufficient tension to maintain it straight and vertical. Suitable brackets may be secured to the hatchway at points intermediate the ends of the tape to prevent displacement. Other features and advantages will become apparent'from the following description and appended claims. v
The invention will be described as embodied in a power dumbwaiter system, suitable, for example, for apartment houses. For simplicity the control of the hoisting motor, and other non-essentials to the understanding of this invention, are omitted. It is to be understood that the invention is applicable tofany type of dumbwaiter or elevator system. V
In the drawings 5 Figure 1 is av schematicrepresentation of a power dumbwaiter system illustrating guides for the moving bodies thereof constructed in accordance with this invention;
Figure 2 is an enlarged horizontal section 750 thereof along the line 22 of Figure 1; and
1929.: Serial o. 382,125.
Referring to the drawings, dumbwaiter car 1 is arranged to travel in-the hatchway2 to serve a'plurality of openings The hoisting ropes runs over a sheave 5 and is connected at oneend tothe topof the (3311131116, at the other end to a counterweight 6. The
two car guides 7 and the two counterweight guides 8 are each formed of a continuous fieX- ilole metallic strip held in tension inzthe V hatchway. In the preferred construction, these guide strips are made of cold rolled steel ofthe desiredv gauge and width.' According -to the construction illustrated, the upper'end of each car guide .strip 7 and the corresponding counterweight guide, strip 8'is fastened 'to anend block 10 'whichis appropriately secured to the beam 11 asby the U-strap 12. The lower endof the guide strips, both for the car and the "counter weight, are secured to tensioning bolts '13 which extend through holes in the flanges of the I-beam 14 to the undersidethereofi Nuts 15 on the ends of the tensioning bolts are screwed up against the underside of theI- beam 14 to secure the. guide stripst'o the I-beam. It is to be noted at this point'that the tension, in the guide strips may be regulated by these nuts 15. n 1
At one or more'places betweentheupper and lower ends of the guide strips there are provided U-frames'16. These U-frames are suitably secured along the ;rear hatchway wall so thatthe ends17 thereof. extend outward from the wall. To each ofthese ends "17, and on the inner side thereof, there is fastened, asby a bolt 18, ajspacer block 20. Each block is arranged to fit between a car guide strip 7 and the adjacent counterweight guide strip 8. 'These guide strips are clamped to. the blocks 20 by means of clampj ing plates-21 which are heldin place'by bolts 22. In this manner the guide stripsarestabilized, excessive movement prevented, and
the spacing between guide strips maintained,
constant. 1 v
The car and the counterweight are each provided. with guide shoes 23 suitably: se-
cured thereto; These shoes may be of any v desired type or construction. For the dumb waiter installation shown, it is preferred to use an oil-less typelform-ed of wood or porous metal impregnated with a suitable lubricant. V V
Attention is directed to the simplicity with which theguide strips may be installed. The
guide strips maybe quickly stretched between and secured to the upper beam 11 and the lower I-beamil lq The proper'ten'sion in the strips may be obtained promptly by the'ad-e. justment of the nuts 15. The strips may then v be clamped to the spacer blocks on the U-frames 16 which have been installed along the hatchway. It'is to be noted that there are no joints to be fitted orf filed smoothin order to get straightguides I -As many changes could be made in the above construction and many apparently Widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter ,containedin the above description or shown 1n the accompanying drawings shall be lnterpreted as. lllustratlve ,and not in'a limiting sense,

2. In: an elevator system,-a guide rail 7 7 formed of a continuous piece of metallic; tape extending the height of the elevator hatchway, and a plurality of adjustable clamps posit-ioned-along said hatchway to'maintain the tape in place throughout the height of the ranged to project the remaining width of the flat faces and the edge 'ofthe tape included therebetween into the hatchway as the guiding faces of the guide rail.
