CAMPBELL ALLEN HARLAN BY W1! 9 ATTORN Y5 United States Patent MOBILE TOWER WITH ELEVATOR FOR MAKING OVERHEAD ASSEMBLIES Campbell Allen Harlan, Birmingham, Mich. Application December 15, 1952, Serial N0. 326,028
9 Claims. (Cl. 214-103) The present invention relates to apparatus for making overhead assemblies.
It is an object of the present invention to provide apparatus for making overhead assemblies comprising a tower having wheels at its lower end by means of which it may readily be moved over the ground or floor.
It is a further object of the present invention to provide a movable towerhaving at its upper end a platform for supporting a workman and a protective rail surrounding the platform.
It is a further object of the present invention to provide a tower of the character described having a trackway extending from top to bottom thereof along one side, and a carriage movable on said trackway.
It is a further object of the present invention to provide a tower of the character described including a trackway which is inclined inwardly and upwardly.
It is a further object of the present invention to provide Patented Sept. 4, 1956 understood that if desired, larger wheels might be emare track members 24 adapted to support a carriage a tower of the character described including a carriage in which the carriage is provided with track engaging means spaced substantially below the upper side thereof to permit movement of said carriage to a position substantially above the upper end of said trackway. 7
Other objects and features of the invention will become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings, wherein:
Figure 1 is a front elevation of a tower constructed in accordance with the present invention. Figure 2 is a side elevation of the tower shown in Figure l.
Figure 3 is a section on the line 3-3, Figure l.
Figure 4 is an enlarged fragmentary elevation, the upper end of 'the' tower showing the carriage inelevated position.
The apparatus for making overhead assemblies comprises a tower made up of front corner posts 19 which are inclined rearwardly and upwardly, and rear corner posts 12 which are herein shown as vertical. The corner posts are interconnected at their lower ends by horizontal frame members 14 and adjacent their upper ends by horizontal frame members 16. Intermediate the frame members 14 and 16, the corner posts are connected by horizontal frame members 18. Carried by the upper frame member 16 is a floor or platform 20 on which the workman stands. The corner posts 10 and 12 extend upwardly above the platform 20 and are interconnected at their upper ends by horizontal frame members 22, thus providing a protective railing surrounding the platform.
tower structure over the floor or ground and these means are illustrated as caster wheels 23 which are located adjacent the bottom corners of the tower. The caster wheels may be mounted for free angular movement about vertical axes so that the tower may be moved readily in any direction. The size of the ground wheels 23 ilmounted generally at 26. As best seen in Figure 3, the track members 24 may be of generally C-shaped crosssection to receive supporting rollers 28 carried by the carriage 26. p
The carriage 26, as best seen in Figure 4, comprises a shelf 30 connected at its read edge to frame members 32 which extend parallel to and lie between the tracks 24. Brace members 34 extend upwardly from frame members 32 to the forward edge of the shelf. The rollers 28 are carried by the frame members 32 and it will be observed in Figure 4 that the supporting rollers 28 are located substantially below the shelf portion 30 of the carriage. It will also be observed in this figure that the tracks 24 extend upwardly to the railing 22, thus when the upper pair of rollers 28 is at the upper end of the track the shelf portion 30 of the carriage is located substantially above the railing 22. This permits the shelf to be raised high enough to position an article carried thereby at proper elevation for direct attachment to supporting structure while it remains supported on the shelf. At the same time, the carriage may be lowered to permit the tower to be moved under depending structure in a building such for example as previously assembled pipes, girders, or the like.
Means are provided for effecting up and down movement of the carriage 26 and this means comprises a drum 36 driven by an electric motor 33 mounted on the tower. Carried by the drum is a cable 40 which extends downwardly from the drum and beneath a sheave 42 and thence upwardly and over a second sheave 44, and thence downwardly substantially in the plane of the trackway where the end of the cable is connected to the carriage 26 adjacent the lower end thereof.
Preferably, control means such as push button switch means illustrated at 46 is provided, and as seen in the figures, this control-means is conveniently located on the railing 22 so that the workman may control the raisingand lowering of the carriage 26.
The shelf portion 30 of the carriage may be provided,
with roller means adapted to cooperate with the particular type of articles being assembled. Thus for example, in Figure 1 the shelf portion 30 is illustrated as provided with a multiplicity of small rollers 56 on which a relatively heavy article may be supported and moved freely longitudinally of the shelf. The rollers 50 may be of about the size and construction of roller skate wheels positioned so that the upper surface thereof defines a horizontal flat plate over which articles may be moved longitudinally of the shelf.
Alternatively, the shelf may be provided with spaced pairs of rolls such as illustrated at 52 in Figure 4, and these rolls will be spaced apart longitudinally of the platform so as to support an elongated cylindrical article such as illustrated at 54. The article 54 may for example,
- be a section of pipe adaptedto be threaded to a pipe Means are provided to facilitate movement of the lustrated in the figures is suitable for use on a cement floor in a partially completed building and it will be moved'reaidily over the floor or ground to any position.-
where assemblies are to be made. providing a carriage having a shelf which may be elevated substantially above any portion of the permanent tower structure, articles carried by the shelf portion of the carriage may be elevated into substantially the exact position in which they are to be assembled. By providing roller means on the shelf of the carriage, movements of the articles carried thereby into exact position are facilitated and, in the case of the rollers 52, suitable rotation of the members may be provided for to permit threading of the articles into assembled position.
Since the elevation of the carriage 26 is under the control of the operator who is standing on the platform 20, it is possible for him to control the raising of the shelf 30 and the article carried thereby into the exact position of elevation required by the assembly. The rearward and upward inclination of the trackway provides for increased stability since upward movement of the carriage results in inward movement thereof, thus causing the loads carried by the shelf of the carriage to be supported more nearly intermediate all of the ground engaging Wheels of the tower.
The drawings and the foregoing specification constitute a description of the improved apparatus for making overhead asssemblies in such full, clear, concise and exact terms as to enable any person skilled in the art to practice the invention, the scope of which is indicated by the appended claims.
