United States Patent O 3,188,759 PIVGTED VER'HCAL GATE C D Lowrey, Quitman, La., .assigner to C. l). Lowrey & Company, Inc. Filed Dee. 6, 1962, Ser. No. 242,716 6 Claims. (Cl. 39-82) This invention relates to a novel and useful pivoted gate and more specifically to a gate primarily designed for use as a swingable closure for the rear end of truck bodies.

When loading and unloading stock the driver of a mobile stock pen usually backs up to a stock delivery chute. yIf the mobile stock pen is provided with a conventional type of gate which is swingable about an ups'tanding axis', the driver must stop short'of the discharge end of the deliveryrchute, dismount and open the gate, and then remount the mobile stock pen and back up the remaining distance to the discharge end of the delivery chutes `By providing a gate which is pivoted for movement about an axis extending transversely of the medial plane'of the gate, the mobile stock pen may be backed up to a point' immediately adjacent the discharge end of a stock delivery chute. Then, the driver has only to pivot the gate about its horizontally disposed axis in order to allowstockto travel from the vdischarge chute into the mobile stock pen.

It is accordingly the main object of this invention to provide a new and useful gate which may be utilized as the closure member for the rear end of mobile stock pensand which is mountedfor swinging movement about a horizontally disposed axis extending substantially normalto the 'medial plane ofthe gate.

Another object of this invention, in accordance with the preceding object, is to provide coacting guide means carried by the -swingable gate member and the upstanding gate post to which it is pivotally mounted for guiding ythe free swinging portion of the gate member against movement laterally of its medial plane during its swinging movement between the' upper open position and the lower closed position.y

Stilly another object of this invention, in accordance with the immediately preceding object, is to provide a swingable gate which is also mounted for swinging movement relative to the atom-mentioned' gatey post about an upstanding axis in a conventional manner in order that the gate may also be used as a conventional gate.

Still another object of this invention is to provide a pivoted gate member in accordance with the preceding objects Which will also be readily adaptable for use in environmentsother than as a swingable closure for the rear end of a mobile stock pen.

. A nal object of this invention to be specifically enumerated herein is to provide a pivoted vertical gate in accordance with the preceding objects which will conform-to conventional forms of manufacture,be of simple construction and easy to handle so as to provide a device that will be economically feasible, long lasting and relatively trouble free in operation. j

Referring now more :specifically to the drawings, the` numeral 10 generally designates the flooring of a mobile stock pen which is provided with a pair of upstanding'

sides

12 and 14 including gate posts 16 and 13 respectively at corresponding ends of the s-

ides

12 and 14.

rEhe pivoted vertical gate assembly of the instant invention is generally designated by the reference numeral' and includes a generally rectangular gate member 22; The gate member 22 includes a pair of

upstandingside members

24 and 26 which are interconnected by means of a plurality of generally parallel horizontal members 28. In addition, the horizontal members Z8 are interfl connected by means of an additional pair of vertical brace members which are spaced inwardly from the upstanding side'

members

24 and 26.

The lower end portion of the gate post 16 has a journal block 32 mounted thereon in any convenient manner such as by welding 34 and a pivot pin 36 projects from the inside face of the gate member 22 and is rotatablyl received in the journal block 32. gate member 22 is mounted for swinging movement about a generally horizontally disposed axis extending ttansversely of the medial plane of the gate member `22 de'- iined by the pivot pin 36:

An arcuate guide member 40 is securedin spaced relation to the inside face of the gate member 22 by means of mounting studs 41 secured Ibetween the gate member' ZZ"- and the arcuate guide member 49. A grooved guide WheelY or follower 42 is rotatably journaled from the'upper end of the gate post 16 by means of a pivot pin 44 and it will be noted from FIGURE 4 of the drawings that the grooved guide wheel or roller 42 is disposed in rolling contacting relation with the outer peripheral surface 46' of the arcuate guide member 40 and that the anges 4S and 50 defined by the groove 52 formed in the wheel 42 are disposedV on opposite sides of the arcuate guide member 40. It will be noted that the axis of rotation of the gate memplane indicated by the section line 8 8" In this manner, tlie' t Y i alaaf/se Y ber 22 defined bythe pivot pin 36 defines the center of curvature of the arcuate guide member 40. Additionally, v.

the opposite ends of the arcuate guide memberY 46 yeach have a radially outwardly. projecting abutment d secured thereto for engagement by the wheel orroller 42 yin order to limit swinging movement of thegate member .about the l-ongitudinal axis of the pivot pin 36 in Vbothdrrections.

f 'From yFIGURESIJ 3, and 6 of Vthedrawings, it may be" seen that an upstanding guide bracket 58 is secured tothe gate post18-and defines, together with the latter, an upwardly opening channel in which the lowerV redge of the gate member 22 is receivable ywhen the gate member 22k .Y Xlyr U-shaped members 112 kandV 1:14 secured to the gate post16 and the side member 2,4. The members 112 and V114y include pairs of apertured legs 1.16 and 11S respectively and the

legs

116 and 118 include

registrable Vlbores

120 and 122 respectively through which a locking pin 1.24 may be passed.

VThe upper portions of the rear ends of the

sides

14 and 16 are interconnected by means of an inverted U- shaped brace assembly generally referred to by the reference' numeral 126 including a pair of depending legs 128 and 13 interconnected at their Vupper ends by means of f a bight portion 132.. The

legs

128 and 130 each include isV moved toward its lowered and closed position illus-V ,A

trated in FIGURES 2 and 3 of the dra-wings. The bracket 58 includesl an L-shaped member 59 including horizontal and vertical legs 6i) and 61, the free end of the horizontal leg 6i) is secured to the gate post 1S anda pair of-brace members 62 are secured between the gate postl andV the vetrical leg 611 at points spaced longitudinally thereal-ong. The upper edge of the uppermost brace member t 62 has an upwardly opening notch 63 formed therein in'- whicha generally horizontal hooked.y abutment memberV 64 is -seatingly,engageableffor ldening the closed position of the pivoted gate member 20. In addition,V a camk strapy `65 is providedv and extends between'rportions ofthe gate post 18 and the leg 61 for camming the free edge of the gate member 22 into engagement with the vertical leg 61 as the gate member 22 is pivoted to the closed position. With attention now ,directed tol FIGURES y7 through 9 of the drawings, there will be scenaV modified form of mobile pen generally referred to by the reference numeral- 66 which lincludes a gate post 68 corresponding to the gate post 16. However, the journal block '7d ofthe stock i' pen 66 is fixed to a sleeve 7-2 beingl rotatably supported from the gate post 68. The journal .block 70 corresponds a large diameter tubularl lower leg section 13,4 and an `upper smalldiameterfleg section 136 telescopingly within the upper end ofthe corresponding lower section 134 and removably secured in adjustedpositions by means of a set screw 138 carried by the corresponding lower section 134. t The bight portion 132 ,rigid-ly interconnects the' upper ends of the upper sections 136. y
