PORTABLE UNIT BUILDING.
Application filed February 7, 1924. Serial No. 691,266.
To all whom it may comem: I
Be it known that I, SAMUEL L. LEWIS, a.
a lurality of compartments formed in the.
building adapted to have the relative size of the compartments increased while the building is in use.
An object of the invention resides in providing a portable unit building structure having a main building section of substantially elongated form, of a size to adapt it to transpor ation from one point to another in which are mounted a plurality of exten sible sections adapted to be housed in the main building structure during transportation, and in such housed position cooperating with the main building to form a plurality of compartments within the same, having communication with one another, rendering the buildings useful in this relation and the sections being extensible to increase the size of the compartment to provide increased housing capacity when the buildin is set up for use at a desired point. Anot er object of the invention resides in providing a three-point suspension for each of the extensible sections, adapting the sections for ready extension and support from the main building.
A further object of the invention resides in providing means cooperating with the supporting structure for the sections and mounted in the main building structure for extending the sections from and returning them to the housed relation relative to the main building structure.
Other objects and improvements in the details of construction and assemblage of the parts are more particularly pointed out in the following description and claim referring to the preferred form of the invention, it being understood. however, that variations may be made from this structure within the scope of the claim.
In the drawings forming a part of this application,
Figure 1 is a side elevation of the improved portable unit building,
Figure 2 is a horizontal sectional view taken on the line 2-2 of Figure 1, showing one of the extensible sections in extended relation, and another similar section in substantially housed relation.
Figure 3 is a vertical longitudinal sectional view-through the unit building.
Figure 4 is a detail sectional view through a portion of the main building structures and one of the extensible sections showing the relationship therebetween, and the operating means for the extensible sections.
Figure 5 is a detail sectional view of the operating means for the extensible section taken on the line 5-5 of Figure 4.
Figure 6 is an enlar ed detail sectional view of the operating means shown in Figure 5 taken at right angles thereto, said view also showing the three art suspension for the extensible section.
Figure 7 is a detail view of one of the supporting rollers. v I
Figure 8 is a detail view of the operating means used in the extension or retraction of one of the extensible sections.
1 indicates the main building structure which is of elongated rectangular form, having sides 2, ends 3, a roof generally indicated at 4, and a bottom or floor section 5.
The section 5 forms the main supporting structure for the building unit and includes longitudinal sills 6 running lengthwise under the sides of the main building structure, which are connected by a plurality of spaced beams or joists 7 to the upper edges of which the floor, indicated by the numeral 8 is secured. The sides and ends are mounted on the floor sections 5 and are provided with a plurality of windows 9 having half sashes and being constructed in any suitab a manner well known in the art, the windows in the side portions being positioned adjacent the ends of the side portions which are formed throughout the central portions with enlarged openings 10 for receiving a pair of extensible building sections 11, having side walls 12, and outer end walls 13,
said side and end walls being provided with Rollers 19 are mounted in the inner ends of the beams 16 adjacent the end member 18 and are ada ted to ride on the floor 8 of the main building structure for providing a point of support for the extensible section. A pair of channel bars 20 are secured to the bar member 15 adjacent the opposite ends thereof and extend through openings 21 the sill 6 and under the floor 8. Rollers 22 are mounted below the opening 21 on the outer sides of the sill 6 and are adapted to support and provide a bearing for' the channel bars 20 intermediate their ends, while the inner ends of the channel bars are positioned over brackets 23 mounted on the under face of the floor 8 which carries rollers 24, which engage the inner ends of the channel bars to provide a second point of support for the channel bars and a third point of support for each of the extensible sections. The inner bottom portion of the channel bar is provided with a plurality of openings 25- for cooperation with the pinion gear 26 mounted on the shaft 27, extending longitudinally of the building and rotatably mounted in the cross beams 7, there being one of these shafts for cooperation with the channel bars of each extensible section. The shafts 27 extend to one end of the buildin as shown, Where they are provided wit ratchets 28 with which cooperate the pawls 29 carried by the operating handles 30 and having spring pressed means 31 for operating the double pawls 29 for cooperation with the ratchet to rotate it in either direction. The operating handle 30 is adapted to extend upwardly through a covered opening 32, so that the sections are extensible and retractible through operation of the shaft 27 from the interior of the building.
It will be noted that the rollers 19, 22, and
24, provide a three point support for the,
extensible sections in order that they may be movable, andat the same time rigidly supported in the main building structure, the inner brackets 23 forming guide brackets for the channel bars to prevent lateral movement thereof in cooperation with the brackets carriedin the rollers 22 so that clined downwardl the extensible sections are always guided in and out in a desirable manner.
Each of the extensible sections 11 is provided with a roof section 33 which is intoward the outer end and provided wit an upstanding projec tion 34 for directing the moisture from the roof of the section onto the corner ortion, the roof in cross section being of arc form, as indicated in Figure 1, so that the moisture will readily drain to the sides of the sections. At the inner open ends of each section, a limiting flange 35 is provided along the upper or roof portion as well as at the side portion for engagement with the side 2 of the building around the opening 10 therein in order to limit the outward movement of each section when being extended to prevent disengagement of the sections from the main building.
Each of the extensible sections 11 is provided across the outer end thereof with a convertible bed 36, adapted to form a lounge or seat for use as indicated in Figure 4, and the end portion of each of the extensible sections 11 is provided with a artition wall 37 at the end ofthe-converti le bed 36 to provide a closet or storage space for clothes or other goods, which is provided with a door 38 for closing the closet.
One end of the building beyond the extensible sections and adjacent thereto is rovided with a partition wall 39 having a cor 40 in the central portion thereof, the compartment 41 formed in the forward end thereof by said partition being provided at one side of the door 40 with a wardrobe 42 having a door 43 communicating with-the interior thereof hinged in the partition 39, access being provided to the wardrobe only when the extensible section 11 at this side of the building is in extended relation.
The compartment 41 adjacent the wardrobe 42 is divided by a partition 44 having the hinged door 45, into a toilet compartment 46, the remainder of the compartment 41 being adapted for use as a kitchen, the stove being indicated at 46 with a shelf at 47. The outer end of the main building provides a compartment 48 which, when the extensible sections are in their outer or extended positions will cooperate to form a large compartment, and when said sections are'in their inner or housed ositions within the main building, the si es of the sections will partition the com artment 48 from the compartment formed y the extension sections and merely leave a passageway providing communications between the sec tions, so that three small compartments are formed in the main building when the extensible sections are in housed relation. A door 49is provided in the front end of the building to form an exit which opens onto a porch 50 rovided as an extensionfrom the end of t e floor section 5 which has the corner posts 51 connecting it with the end of the roof section 4 projecting over the porch, and steps 52, the side' portions of which are hingedly connected with the porch 50 so that the steps maybe moved around the pivots and onto the porch'when the building is being transported from one place to the other. 7
From the above descri tion, it will be seen that a portable buildlng structure has been provided of such a character that it is easily transported from place to place on a flat car or in any other suitable manner, and during transportation may be used, as the partme'nts, and which may be set up at any desired point on suitable supports which are not shown, above the ground, and the extensible parts moved to their outward position to rovide a maximum housing space. It wil also be noted that the extensible sections in having a three point support in the main building structure do not require the provision of any additional supporting structure for the sections while in extended position and that o eration of the handle 30' will quickly an extension of the sections.
What is claimed is:
A portable unit building including a main building of elongated rectangular form having enlarged central openings in the side walls thereof, a pair of extensible. I sections 'movable in the central openings of readily effect a withdrawal or section carried by a pair of spaced rollers.
mounted in the floor section of the main building for guiding and movably supporting said bar and sections, said sections also being provided with rollers along the inner lower edge cooperating with the supporting rollers for the channel bars to provide a.
three point support for each section, and operating means cooperating with the channel bars and mounted in the main building for moving saidsections into extended or housed relation with respect to the main building structure. a
In testimony whereof I affix my signature.
