Definitions
- Another object of this invention is to provide a hoisting and transporting apparatus which is adapted to engage and lift one end of the table, such as a sewing machine table, and maintain the elevated table in a level position while the apparatus is moved to the desired new table location.
- a further object of this invention is to provide an apparatus for hoisting and transporting a table including a frame mounted on Wheels for receiving one end of the table and a jack and guiding mechanism mounted on the frame for elevating-and lowering the table and maintaining the table constantly level in all positions.
- FIG. 1 is a side elevation of the invention operatively supporting a sewing machine table in an elevated level position, shown in phantom;
- FIG. 2 is a rear end elevation of the invention disclosed in FIG. 1;
- FIG. 3 is a fragmentary top plan view taken substantially along the line 3-3 of FIG. 2.
- the apparatus 10 is designed to elevate, lower and transport a table, such as the table 11 supporting a sewing machine 12.
- the sewing machine table 11 is provided with legs, such as the right end legs 13 and 14 connected at their upper ends by a channel-shaped transverse beam 15, which also supports the table top 16.
- the apparatus 10 includes a U-shaped frame member 19 including a transverse portion 20 and a pair of longitudinal portions 21 and 22, extending forwardly from opposite ends of the transverse portion 20, and on opposite sides of the table 11 when the apparatus 10 is in operative position for receiving the table.
- a pair of wheels 23 and 24 are afiixed to and depend from the forward extremities of the longitudinal portions 21 and 22.
- a pair of rear wheels or casters 25 and 26 are swivelly mounted to, and depend from, the transverse member 20, so that all the wheels 23, 24, 25 and 26 are adapted to engage a sup- Patented Nov. 22, 1966 porting surface, such as a floor 28, for supporting the frame member 19 in a substantially horizontal position.
- a pair of brace arms 30 and 31 Extending upwardly and rearwardly from the longitudinal frame portions 21 and 22 are a pair of brace arms 30 and 31, disposed on opposite sides of the table 11 in operative position, and connected at their upper ends by a transverse handle bar 32.
- a rack bar 35 Extending in an upright position and fixed to the transverse frame portion 20 is a rack bar 35.
- the upper end of the rack bar 35 is fixed to an upper transverse bar 36, which in turn is secured to the upper extremities of the opposite side braces 30 and 31.
- a conventional jack head 38 Slidably mounted upon the rack bar 35 is a conventional jack head 38 including a ratchet and pawl mechanism for engaging the rack bar 35, and a lever 39 for actuating the jack head 38 in order to move the jack head 38 step-by-step along the rack bar 35 either upwardly or downwardly, depending upon the position of the conventional reversing mechanism 40.
- a conventional automobile bumper jack may be adapted for use as the rack bar 35, jack head 38 and lever 39 incorporated in the apparatus 10.
- Pivotally mounted upon the front face of the jack head 38 is a hook 42 which is adapted to fit beneath and engage the transverse beam 15.
- a transverse bar or axle 44 Spaced below the hook 42 is a transverse bar or axle 44 rigidly fixed between the longitudinal frame member portions 21 and 22.
- the axle 44 supports a sleeve or roller 45 for free rotatable movement.
- the longitudinal spacing of the hook 42 and the roller 45 is such that when the hook 42 engages beneath the flange of the channel member 15, the lower portions of the table legs 13 and 14 will abut against the roller 45, in vertical position, so that the table top 15 will be maintained level while the table 11 is being elevated, lowered or transported by the apparatus 10.
- the rack bar 35 and consequently the plane of the transverse bar 36 and transverse frame member portion 20, are not truly vertical. Instead, the rack bar 35' extends upwardly and slightly forwardly to accommodate the longitudinal spacing of the hook 42 and the roller 45 so that the legs 13 and 14 will be disposed in a vertical plane in operative position.
- the transverse rod 44 is provided with the roller 45 so that the lower portions of the legs 13 and 14 will be in rolling engagement with the transverse rod 44 as the jack head 38, and the table 11, are moved vertically along the rack bar 35.
- the rack bar 35' could be mounted truly vertical bymounting the roller axle 44 closer to the rear of the apparatus 10.
- roller bar 44 must be spaced a sufficient distance above the floor 28 to permit continuous engagement of the legs 13 and 14 with the roller 44 for any desired elevation of the table 11 by the apparatus 10.
- the length of the longitudinal frame portions 21 and 22 must extend sufliciently forwardly to provide stability for the apparatus 10 when it is hoisting and transporting a table 11, and to prevent tilting of the apparatus 10 by the table 11.
- the length of the longitudinal portions 21 and 22 must be such that the sum of the moments about the axis of the wheels 23 and 24 must equal zero. This will of course, depend upon the locations of the center of gravity of the combined table 11 and sewing machine 12 and the center of gravity of the apparatus 10, and the weight of the combined table 11 and machine 12 and the weight of the apparatus 10.
- the apparatus 10 In order to operate the apparatus 10, for example to move the table 11 from an original stationary position to a new location, the apparatus 10 is manually pushed by the handle bar 22 toward and encompassing one end of the table 11, such as the right end disclosed in FIG. 1. The right end of the table 11 is received between the hook 42 can be moved forwardly beneath the beam 15.
- the reversing mechanism 40 on the jack head 38 is switched to the up position.
- the lever 39 is then reciprocated, moving the jack head 38 upwardly upon the rack bar 35 causing the hook 42 to firmly engage and lift the channel beam 15, causing the table 11 to be hoisted.
- the roller guide 45 maintains the legs 13 and 14 in vertical position so that the table top 16 will always be maintained level during the hoisting operation.
- reversing mechanism 40 is changed to the down position, the lever 39 is again manipulated to lower the jack head 38 and the hook 42 in a step-by-step movement until the legs of the table engage the floor 28.
- the downward movement of the jack head 38 is continued until the hook 42 has cleared the transverse beam 15, and the handle bar 32 is grasped to pull the apparatus 10 rearwardly away from the table 11..
- the rack bar 35 is not exactly centered between the brace arms 30 and 31, but is spaced slightly closer to the brace arm 31. This off-center position of the rack bar 35 is designed to balance the various forces acting on the apparatus 10 and the sewing machine table 11, because of the shape of the legs 13 and 14, and also because of the oif-center location of the sewing machine 12 on the table 11.
- An apparatus for hoisting and transporting a table comprising:
- a jack head including a ratchet and pawl mechanism for step-by-step movement along said rack
- hook means on said jack head adapted to engage beneath the top of said table to lift said table upon actuation of said jack head
- transverse member fixed to said frame and spaced below and so located with respect to said hookl means that said transverse member will guide the lower portion of said table vertically to maintain said table top level While said table is being hoisted and transported.
- frame is substantially U-shaped having a transverse por-. tion and a pair of longitudinal-portions extending from opposite ends of said transverse portion, said longitudinal portions being adapted to extend along opposite sides of said table.
- said supporting wheels include a wheel mounted on each longitudinal portion of said frame remote from said transverse portion, and at least onecaster mounted on said transverse portion.
- An apparatus for hoisting and transporting a table comprising:
- a jack head including a ratchet and pawl mechanism for step-by-step movement along said rack
- transverse roller fixed to said frame and extend ing between said longitudinal portions and spaced adjacent said transverse portion for rollably engaging the lower portion of said table, (h) said transverse roller being spaced below said engaging means for guiding the lower portion of said table vertically while said table is being hoisted and transported.
