LOUIS E. OWENS, OF PEORIA, ILLINOIS RUG-DRYING APPARATUS Application filed November 23, 1928. Serial No. 321,498.
The present invention relates generally to a rug drying apparatus and more particularly to an improved hoisting construction therefor. The prime object resides in the provision of a single shaft for operating a plurality of drums and means for individually locking the drums to the shaft for rotation therewith.
Another very important object of the invention resides in the provision of an improved structure of this nature which is exceedingly simple, inexpensive to manufacture, easy to assemble and disassemble, com- 15 pact and convenient in its arrangement of parts, strong and durable, thoroughly efficient and reliable in operation, and otherwise well adapted to the purpose for which it is designed.
With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawing:
Figure 1 is an elevation of the apparatus embodying the features of my invention,
30 Figure 2 is another elevation thereof taken at right angles to that shown in Figure 1,
Figure 3 is a sectional elevation showing fragmentarily a plurality of the drums on the shaft,
Figure at is a transverse section taken substantially on the line 4% of Figure 3,
Figure 5 is an enlarged detail section showing the latch in a disengaged position,
Figure 6 is a fragmentary view of the to shaft showing one of the recesses therein,
Figure 7 is a detail section taken substantially on the line 77 of Figure 5.
Referring to the drawing in detail, it will be seen that numerals 5 denote suitable brackets mounted along the lower portion of a side wall 6 of a room and having suitable bearings 7 for rotatably receiving a shaft disposed horizontally and provided at spaced intervals with oblong recesses 8.
I This shaft is operable through suitable gearing 9 and a crank 10. A plurality of drums llare rotatably mounted on the shaft 12 in end to end relation as is indicated to advantage in Figures 2 and 3. Since all of these drums are identical in construe tion only one will be described in detail.
Each drum 11 includes a flange 14-at one end and a ratchet wheel 15 at the'other end. A hub like portion 16' extends beyond the wheel 15 and has threadedly engaged therein a bolt housing 17 in which is slidably mounted a bolt 18 for engaging in the adjacent recess 8. This bolt 18 is spring pressed toward the shaft as is indicated at 19, the spring impinging against the outer end of the casing and a shoulder on the bolt and being disposed about a stem 20 extend ing from the bolt and slidable through the outer end of the casing 17 having threaded on its outer end a knurled knob 22 'held in place by a lock nut 23.
This knob 23 is provided with. an opening 24. A pin 25 projects from the outer end; of the casing 17 and when the bolt is in a released position, the outer end of this pin fits in the recess 25 in the inner surface of the knob 22 but when the bolt is in an en.- gaging position in the recess 8 said pin extends through the opening 24 and a lug 27 projected from the outer end'of the casing 17 is seated in the recess 26.
The locked position is'shown in Figure 3 and the release position is shown in Figure 5. A bracket 28 is mounted on the wall 6 and pivotally supports a pawl 29 engaged with the ratchet wheel 15 so as to prevent unwinding of the drum except when the pawl is released as will be apparent.
In one practical embodiment'of the invention a pair of cables 30 are windable. on the drum and are trained over pulleys 31 suspended from the ceiling 32. A bar 33 is supported by these cables 30.
There are, of course, an equal number of bars with the drums. It will be readily appreciated that one or more rugs may be attachedto the bars 33 in the usual manner and the corresponding drums may be locked to the shaft 12 and then by operating the crank the bars may be hoisted up without disturbing any of the other drums or bars.
The convenience and compactness of this arrangement will be quite obvious. It will further be seen that the mechanism is easy to manipulate, not likely to easily become out of order, simple in constructiomeasy to maintain in proper operation and lubrication because of orifices a0 and 41 and it will also be noted that the interior of the drum intermediate its ends is hollowed out as at 42 to contain or store a proper amount of lubricant.
It is thoughtthat the operation, construction, utility and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof.
The present embodiment of the invention has been disclosed in considerable detail merely for the purposes of exeinplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.
It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing'from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, What I claim as new is:
1. In a mechanism of the class described, a shaft, a plurality of drums, said drums being rotatable on a fixed axis, a bolt housing threaded into each drum, said shaft having a plurality of recesses one adjacent each housing, a spring pressed bolt adjacent each housing, a stem extending from each bolt, a knob on the stem'having an opening, a pin on the housing to project through the opening so that the spring may urge the bolt into the respective recess or the knob may be turned so that the pin Will'hold the knob and the stem in a position with the bolt released from engagement with the recess.
2. Ina mechanism of'the class described, a shaft, a plurality of drums, said drums being rotatable on a fixed axis, a bolt housing threaded into each drum, said shaft having a plurality of recesses one adjacent each housing, a spring pressed bolt adjacent each housing, a stem extending from each bolt, a knob on the stem having an opening, a pin on the housing to project through the opening so that the spring may urge the bolt into the respective recess or the knob may be turned so that the pin will hold the knob and the stem in a position with the bolt released from engagement with the recess, each drum including a flange at one end and a ratchet wheel atthe other end,
and a pivotally mounted pawl associated with each ratchet wheel.
3. In a mechanism of the class described, comprising a single shaft, a plurality of drums rotatably mounted on the shaft, said drums being rotatable on a fixed axis, said shafts being formed with notches, one adjacent each drum, a spring pressed bolt supported on each drum, selectively engageable with said notches, means for holding the bolts disengaged from the respective recesses, a gear on each drum, a pawl engageable with the gear for preventing the drum from unwinding, and means for rotating the'shaft;
In testimony whereof I aflix my signature.
