Definitions

  • 187-6 4 Claims ABSTRACT OF THE DISCLOSURE Hoist apparatus comprising a tubular track affixed to a vertical wall and made up of a plurality of reinforced, polygonal-shaped sections, the side walls of the tubular track intersecting in vertical corners within which the wheels of a carriage permanently installed inside of the track are rotatably supported.
  • An elevator car is removably attached to the carriage through a slot extendv ing the length of the tubular track, and a safety, brake mechanism is mounted on the carriage.
  • the brake mechanism includes spring-loaded brake shoes which are urged outwardly into frictional engagement with the inside walls of the tubular track in response to the severing of the lift cable for the carriage.
  • the carriage wheels are rotatably supported on pivotal brackets and are biased outwardly against the inside of the tubular track by shock absorbing springs.
  • An especially significant feature of my invention resides in the utilization of a brake mechanism which is mounted on the permanently-installed carriage, and which incorporates brake shoes which are movable into frictional engagement with the tubular track by an actuating spring which is normally held in a non-braking position by the tension of the lift cable attached tothe elevator carriage.
  • the carriage wheels are pivotally mounted on brackets and are urged into engagement with the track by shock absorbing springs.
  • FIG. 1 is a side, elevation view showing the hoist apparatus mounted against a vertical wall
  • FIG. 2 is a side, elevation view of the carriage for the elevator car
  • FIG. 3 is a front, elevation view of the car carriage
  • FIG. 4 is a top, plan view of the carriage and track assembly
  • FIG. 5 is a side, elevation view showing the tubular track in its upright, installed position
  • FIG. 6 is a horizontal, section view of the track taken along lines 66 of FIG. 5;
  • FIG. 7 is a perspective view of one of the track mounting brackets
  • FIG. 8 is a side, elevation view of the mounting assembly for one of the carriage wheels
  • FIG. 9 is a front, elevation view of the wheel assembly of FIG. 8.
  • FIG. 10 is a horizontal, section view taken along lines 1010 of FIG. 2, and showing the connection between the lower end of the elevator car and the movable carnage.
  • the elevator assembly of this invention is comprised of an elongated, tubular track 1 on which an elevator car assembly 2 is movably mounted.
  • Elevator car assembly 2 is comprised of a passenger or equipment-carrying car 4 and a carriage or dolly 6 which is permanently mounted within tubular track 1, car 4 being removably attached to carriage 6 in a manner explained below.
  • Carriage 6 is movably supported within track 1 by means of cables 8 and 10, only one of which is shown in FIG. 1. These cables form a closed loop around pulleys 12 and 14 at the top and bottom of track 1, and are secured at their free ends to the top and bottom ends of carriage 6.
  • Power is supplied to the lower pulley assembly 14 by a reversible motor 16 housed within a removable power unit 18.
  • Track 1 is shown secured to a vertical wall -3 which may be an upright portion of a building, tower or industrial chimney.
  • the elevator tower of this invention has been particularly designed with a view towards servicing industrial chimneys which may be as high as 600 feet, the hoist apparatus would be equally useful for construction or repair operations on a building or for fire fighting purposes.
  • track 1 is comprised of a plurality of sections 5, 7 and 9 of polygonal cross section. Although three sections are shown, any number of sections could obviously be employed depending upon the height of the tower or building to which the hoist apparatus is to be attached.
  • the individual track sections are provided with reinforcing collar assemblies 20 at spaced points along their lengths in order to rigidify the track assembly and to support tubular track 1 against the outward forces generated by carriage 6 as it moves up and down within track 1.
  • Each collar assembly 20 is comprised of an inner collar 22 which conforms to the polygonal shape of track 1, and an outer reinforcing ring 24.
  • a mounting bracket 26 is secured to each of the reinforcing rings 24 and is provided with vertically extending slots 28 through which fasteners may be attached to wall 3. Slots 28 accommodate a degree of vertical expansion and contraction of the track 1.
  • Bottom and midtrack sections 5 and 7 each have a collar assembly 20 attached to their upper ends, as by Welding, with the upper ends of these track sections terminating substantially at the middle of inner collar 22 in the manner indicated in FIG. 5.
  • Collars 22 slidably receive the next higher track section, and thereby serve as coupling members.
  • a plurality of reinforcing collar assemblies 20 are mounted on each of the separate track sections 5, 7, and 9 at spaced points along their lengths between the coupling joints between sections, and attached to wall 3, in order to provide proper support and strength for the entire track assembly.
  • carriage 6 is comprised of a vertically extending outer shell 30 to which top and bottom walls 32 and 34 are secured.
  • Cable attachment rods 36 and 38 project vertically from top and bottom walls 32 and 34, and are provided with bifurcated end portions 39 and 40 to which cable attachment fittings 41 and 42 are secured.
  • the upper and lower ends of parallel cables 8 and are attached to fittings 41 and 42 respectively through apertures '43 and 44 therein.
  • Cable drive motor 16 may be reversibly operated from elevator car 4 so as to move the car assembly 2 up and down on track 1 by a control cable or by a remote control radio.
  • Four wheels 45 are mounted on carriage top wall 32 by brackets 47, and a similar set of wheels 46 is suspended from carriage bottom wall 44 by brackets 48.
  • Each of the wheels 45 and 46 rotatably engages track 1 along one of the vertical corners 50 formed between the intersecting side walls 52 of polygonal-shaped track 1 in the manner indicated in FIG. 4.
  • Vertically extending corners 50 serve to guide wheels 45 and 46, and the diametrically opposed disposition of each set of wheels 45 and 46, as shown in FIG. 4, supports carriage 6 against vertical, wobbling movement.
  • Each of the track sections 5, '7 and 9 are provided with a vertically extending, longitudinal slot 54, and these slots are aligned when the several track sections are coupled together, thereby providing a continuous slot which runs lengthwise of tubular track 1.
  • the marginal edges of slot 54 are formed by inwardly turned, oppositely directed flanges 56 and 58 formed in each of the track sections.
  • Flanges 54 and 56 cooperate with the adjacent side wall sections 52 of track 1 to form vertically extending breaks or corners 57 and 59 which supportably engage and guide two upper wheels 45 and two of the lower wheels 46.
  • Oppositely directed flanges 54 and 56 bear against wheels 45 and 46 and restrain carriage 6 against lateral movement in either a clockwise or counter-clockwise direction.
  • carriage 6 is provided with projecting bracket arms 60 and 62 which extend outwardly through slot 54 and removably support elevator car 4.
  • Upper bracket arm 60 includes horizontally extending, upright flange 64 which supportably engages complementary channel member 66 of car 4, as shown in phantom lines in FIG. 2.
  • Lower bracket arm 62 is apertured at 68, and is removably connected to bifurcated connector arm 70 of car 4 by pin 71 in the manner shown in FIG. 10.
  • Car 4 may thus be very easily moved from carriage 6 and used on a multiplicity of tower installations incorporating a permanent track and carriage assembly identical to track 1 and carriage 6.
  • FIGS. 8 and 9 depict the mounting assembly for one of the upper, pivotal Wheels 45.
  • the two pivotal upper brackets 47 are provided with integral collars 74 which pivot about pins 76 supported in sleeves 78 secured to top carriage wall 32.
  • Springs 72 mounted within guide cylinders 80 bear against the inner end of brackets 47, thereby urging attached wheels 45 outwardly into engagement with the inner surface of tubular track 1.
  • Brackets 47 are further supported by guide pins 82 which slide back and forth within slotted members 84.
  • Springs 72 also serve to absorb the shock forces generated when wheels 45 and 46 pass over uneven portions of track 1, thus causing brackets 47 to pivot inwardly and downwardly against springs 72.
  • the brake mechanism is mounted entirely on carriage 6, and includes as the braking means a pair of brake shoes 86 and 88. Brake shoes 86 and 88 are pivotally mounted on pins 90 and 9'1,-and include an outer braking surface 92 which is contoured so as to cam against the inner surface of track 1 when shoes 86 and 88 are pivoted downwardly.
  • Brake shoes 86 and 88 are supported and actuated by movable, bifurcated bracket 94 which carries a pin 96 at its lower end extending through slots 98 in brake shoes .86 and 88.
  • Upper, cable attachment rod 36 is slidably mounted through top wall 32 of carriage 6 and is secured at its lower end to bracket 94 by lock nut 95.
  • Spring 100 embraces rod 36 between top wall 32 and the top of-bracket 94, and is enclosed within guide sleeve 102. Spring 100 is compressed, and the downward force which it normally tends to exert on movable bracket 94is countered by the tension force of cables 8 and 10 acting through connecting rod36.
  • spring 100 would then act to force bracket 94 downwardly, thereby pivoting brake shoes 86 and 88 in a downward direction and urging cammed braking surfaces 92 outwardly through apertures 93 in carriage shell 30 into frictional contact with the inner wall of tubular track 1.
  • spring-biased brake shoes responsive to the severing of the hoist lift cable could be applied equallywell to an elevator or hoist structure having the car assembly movably mounted on the outside rather than on the inside of the track.
  • the permanent mounting of the brake mechanism, as well as the carriage and cable assembly, within tubular track 1 not only protects these elements from the corrosive and wearing effects of wind and weather, but also improves the overall appearance of the elevator structure since the only elements visible are the car 4 and track 1. Also, the mounting of the brake mechanism on permanently installed carriage 6 rather than on removable car 4 greatly simplifies the removal and multiple application of car 4.
  • Hoist apparatus comprising:
  • an elongated tubular track adapted to be secured to a vertically extending wall member, said track being of polygonal cross section and having a plurality of side walls intersecting in vertically extending corners;
  • tubular track has an elongated slot extending along the portion thereof facing away from said wall member, and wherein;
