Description
1319~7~
This invention relates to a winch device, and in particular to a winch device which may be portable or fixed.
The invention is based on the discovery that a simple, readily available off-the-shelf brake slack adjuster can be used in combination with a spool mounted in a frame to provide a simple winch for relatively heavy loads. Brake slack adjusters are well-known, relatively inexpensive, commercially available structures. An example of such a structure is described in U.S. Patent No. 2,156,154, which issued to H.H. Hooker on April 25, 1939. Basically, such structures include an elongated body containing an annular or ring gear, which is driven by a worm, the gear having internal alternating grooves and splines for engaging a splined shaft to rotate the latter.
Winches or lifting devices of generally the type proposed by applicant are described, for example in U.S.
Patents Nos. 2,~33,692, which issued to H.S. Geer on December 30, 1947 and 2,521,191, which issued to J.K. Stanland on September 5, 1950. The Geer and Stanland structures are manufactured from scratch, and consequently are relatively expensive to produce, requiring molded or machine produced components.
The object of the present invention is to provide a relatively simple winch, which is easy to produce using existing, off-the-shelf hardware.
131~6~
Accordingly, the present invention relates to a winch device comerising casing means; spool means mounted for rotation in said casing means; cable means on said spool means for connection to the article to be raised or lowered: and slack adjuster means mounted on sai~lcasing means and connected to said spool means for rotating the latter, whereby the cable means can be wound onto or off of said spool means to tension said cable means or raise or lower on article.
The invention will be dPscribed in greater detail with reference to the accompanying drawings, which illustrate preferred embodiments of the invention, and wherein:
Figure l is a perspective view from above of a winch device in accordance with the peesent invention;
Figure 2 is a front view of the device of Fig. l;
Figure 3 iB a side view of the device of Figs. l and 2 Figure 4 is a schematic, per6pective view of a slack adju~ter used in the device of the present invention;
Figure 5 iB a perspective view from above of a second embodiment of the device of the pre6ent invention; and Figure 6 is a front view of the device of Fig. 5.
Figure 7 i~ a perspective view from one end of a trailer incorporating a third embodiment of the winch device of the present invention;
Figure 8 i~ a per~pective view from one end of the winch device of Fig. 7; and ~3~7~
Figure 9 is a perspective view from the other end of the winch device of Fig. 7.
Referring to Figs. 1 to 3 of the drawings, one embodiment of the winch device of the present invention includes a casing generally indicated at 1. The casing 1 defined by a top wall 2, pair of parallel, spaced apart side walls 3, a bottom wall 4 and a crossbar 5. A spool 6 carrying a cable 7 is rotatably mounted in bearings 9 (one shown) in the side walls 3. A brake for the cable 7 on the spool 6 is defined by a pair of plates 10 (one shown) connected to the crossbar 5 by bolts 12. A swivel hook 13 is suspended from the bottom wall 4 using an eye bolt 14 and a nut 16.
The spool 6 is rotated by a slack adjuster generally indicated at 17. In the present case, the slack adjuster 17 (Fig. 4) is an off-the-shelf item obtained from Brunner-Fleet Products, and includes an elongated body 19 with a row of openings 20 in one end thereof. One of the openings 20 is u~ed in conjunction with a bolt 22 and a nut 23 (Fig. 2) to attach one end of the clack adjuster 17 to one side wall 3 of the casing. The slack adjuster includes an annular gear 25 with internal alternating splines 26 and grooves 27 for connecting the slack adjuster to a splined shaft 29 (Fig. 2) for rotating the spool 6. The teeth 30 on the outer periphery of the gear 25 are engaged by a worm 32, which is connected to a bolt 33 by a coupler 35. Thus, the bolt 33 is in driving connection with the worm 32. The gear 25, the worm 32, the 131~67~
bolt 33 and the coupler 35 are normally housed in the larger end 36 of the slack adjuster body l9. ~he bolt 33 is rotated by means of a simple crank 38 (Figs. 1 to 3), which includes an elongated lever 39 and a handle 40. The outer end 42 of the splined shaft 29 extends beyond the slack adjuster 17, so that the splined portion of the shaft 29 can be moved longitudinally into and out of engagement with the grooves 27 in the gear 25, i.e. the spool 6 can be rendered free wheeling.
The second embodiment of the invention shown in Figs. 5 and 6 is intended for raising and lowering an overhead garage door (not shown). The second embodiment includes a casing generally indicated at 45 of U-shaped cross section.
The casing is defined by a rear wall 46 and a pair of side walls 48 integral with the rear wall 46 for mounting beside a garage door in the location normally occupied by the cable, ~pring and pulley system. A spool 49 carrying a cable 50 is rotatably mounted in bushings ~not shown) in the casing 45.
One end of the cable 50 is connected to a loop 51 on the top end of the rear wall 46 of the casing 45. The cable 50 passes around a pulley system (not shown) and returns to the spool 49, so that the door can be raised or lowered depending on the direction of rotation of the spool 49. A shaft 53 extends through a side wall 48 from one end of the spool 49 into the slack adjuster 17. Because the slack adjuster 17 i8 the same as the slack adjuster used in the first embodiment of the 1 3 ~
invention, no additional detailed description of such slack adjuster is provided. The slack adjuster 17 is connected to the side wali 48 of the casing 45 by a bolt 54 extending through one of the holes 20 and the wall 48 into a nut 55.
With reference to Figs. 7 o 2, a third embodiment of the device of the present invention which is generally indicated at 60 is intended for use on a trailer 61 or other vehicle for tightening straps 62 on a load 63. The device includes a generally U-shaped casing 65 defined by a bottom or rear wall 66 and a pair of side walls 68 and 69 integral with the rear wall 66. A threaded hole 70 (Fig. 9) is provided in the rear wall 66 for receiving a bolt 71 (Fig. 8) for mounting the casing 65 on the trailer 61.
A spool (not shown) carrying a strap 62 is rotatably mounted in the bushings 72 in the side walls 68 and 69. A
shaft (not shown) extends through the side wall 78 into a slack adjuster 17 is shortened by cutting and the bottom free end 73 thereof extends into a rectangular notch 75 in a flange 76 welded to the rear wall 66 of the casing 65.
During use the straps pass over the load 63 to a fixed bracket or clasp (not shown) on the other side of the trailer 61 from the device 60. By actuating the slack adjuster 17 to rotate the spool, the strap 62 is tightened or loosened.
~31~7~
It will be appreciated that the bolt 37 of the slack adjuster 17 can be rotated manually using the crank 38, or mechanically using an electric drill and socket attachment or a pneumatic wrench of the type used to remove and mount vehicle wheels.
In the foregoing description of the preferred embodiment the term "winch device" has been given a broad definition. The basic combination proposed by the present inventor and falling within the definition includes a casing, a spool in the casing, a cable (which may be a strap) on the spool) and a slack adjuster for rotating the spool.
