Claims priority, application Canada April 19, 1955 4 Claims. (Cl. 214-1) This invention relates to a device for loading bombs or the like.
Previously known bomb loading devices, which have used a hydraulic cylinder acting .to upwardly bias an arm carrying means for supporting the bomb, have been subject to the disadvantage that it has been necessary to adjust the inclination of the means for supporting the bomb after the bomb has been raised. Thus, in my prior Canadian Patent 505,425, dated August 31, 1954, a turnbuckle was used to adjust the inclination of the bomb. Furthermore, it was necessary either continuously to adjust the angle of inclination of the bomb as it was raised, or to fasten the bomb securely to the bomb supporting means so that the bomb would not fall off the bomb supporting means as it was raised.
Bombs are referred to above merely as examples of the type of article dealt with by the apparatus of the invention. The apparatus is also applicable to loading similar articles to bombs such as rockets, torpedoes, guided missiles, other projectiles and weapons and similarly shaped objects such as aircraft jet engines.
One object of this invention, in accordance with one aspect thereof, is to provide means for automatically retaining the bomb supporting means at a constant angle of inclination to the horizontal while it is being raised and lowered. As the bomb supporting means does not tilt as the bomb is being raised, the bomb does not have to be securely lashed to the bomb supporting means for many purposes. It is sufficient that the bomb rest in position on the bomb supporting means under its own weight.
A further disadvantage of previous bomb loading de- J vices was that it was difficult to load the bomb onto the bomb loading device. A further object of the preferred embodiment of this invention is to provide simple and convenient means for transferring the bomb onto the bomb loading device.
Another disadvantage of previous bomb loading devices was that it was necessary to maneuver the entire carriage to make minor adjustments to the position of the bomb so that it would be received by the structure onto which it was being loaded. A further object of this invention, in accordance with its preferred embodiment, is to provide for adjustments of the bomb supporting means in any horizontal direction. Preferably, provision is also included for tilting movement and rotary movement of the bomb about a vertical axis to provide a maximum flexibility of adjustment without it being necessary to move the main carriage.
The manner in which these objects are accomplished, in accordance with this invention, will be apparent from the detailed description which follows and from the appended claims.
In the drawings which illustrate the preferred embodiment of this invention:
Figure l is an elevation view of the bomb loading device.
Figure 2 is a plan view of the device shown in Figure 1;
in Figure 2 the loading boom and its supporting structure have been omitted for clarity of illustration.
Figure 3 is a detailed perspective view partially broken away of the bomb supporting platform and its mountings.
Figure 4 illustrates a general purpose maintenance platform which can be mounted on the bomb supporting means.
Figure 5 is a detailed sectional elevation of part of drums 75 and 76.
Referring now to Figures 1 and 2 of the drawings, the bomb loading device comprises a wheeled carrier which includes front plate It beneath which front wheel 11 is mounted by fork 12. Fork 12 is pivotally mounted beneath plate It) by pin 13. A draw bar 14 is attached to fork 12 for steering the device. The supporting frame members 15 for front plate have rearwardly and downwardly angled portions 16 secured to frame members 17. Frame members and 17 are also connected by members 18. A plate 19 is mounted on the portion of frame members 17 beneath members 15 to provide a mounting for hydraulic motor 20. Frame members 17 diverge rearwardly to provide a broad wheel base for the rear wheels, and are connected together at the rearward portion of the device by transverse frame members 21, 22 and 23. Wheels 24 are mounted on shaft 25 at the rearward end of the device. If desired, stabilizer arms 26 can be provided. These can conveniently be pivotally mounted on flanges 27, which extend laterally from frame members 16 and 17 respectively. The stabilizing members 26 include a stabilizing head 28, an arm 29 of constant length, and an arm 30 the length of which is adjustable by the manipulation of turnbuckle 31. Turnbuckle 31 enables the stabilizing arms to be adjusted with head 28 bearing on the ground and with the stabilizing arms spread into the outwardly diverging position shown in Figure 2. The stabilizing arms provide a useful safety feature if a heavy load is to be raised when the device is on inclined ground, or if the device is to be used on board ship. The stabilizing arms can be folded inwardly to the position shown in Figure 1.
Suitable brakes 32, which are shown only in Figure 1, can be provided to bear on rear wheels 24.
Supporting plates 33 are mounted on each of frame members 16 to provide mountings for the lifting arms. Upper lifting arm 34, which is shown as being a channel shaped member, is pivotally mounted on plate 33 at 35, and extends rearwardly to a pivotal connection at 36 with the mounting base 37 for the bomb carrying platform. A lower lifting arm 38 is pivotally mounted on plate 33 by pin 39, and is pivotally connected to mounting base 37 by pin 40. The pivot points provided by pins 35, 36, 40 and 39 are arranged in the form of a parallelogram so that, as the lifting arms are raised, the mounting base 37 and consequently the platform mounted on it will remain at a constant angle of inclination to the ground. Platform 41 is mounted on mounting base 40, and bomb holding means are provided on platform 41 by rollers 42, which are carried between plates 43 and which are rectangularly disposed so that the bomb will be received between the rollers. Plates 43 are secured to transverse members 44, which in turn are bolted by bolts 45 to transverse members 46 of the platform.
Upper lifting arm 34 has a crank-like extension 47, the end of which is connected to link 48. The links 48 on each side of the device are connected by cross head 49. Hydraulic cylinder 5% is energized by motor 20 and acts to pivot arms 47 rearwardly, causing lifting arms 34 to be raised. Lifting arm 38 is automatically raised with lifting arms 34.
A supporting frame consisting of upright members 51 and 52, transverse member 53, and braces 54, is mounted on frame members 15 at the forward end of the device.
3 A lifting boom 55, which comprises members 56 and 57 connected by bracing member 58 and plate 59, is pivotally connected to the upper end of member 51 by a quickrelease pin 613. At the head portion 61 of the lifting boom there is a pulley 62, over which passes a chain 63 carrying a book 64. A suitable winch 65 controls the length of chain 63 to raise and lower lifting means 64. The winch 65 which has been illustrated is a manually operated winch, but the winch can also be power operated. A hydraulic cylinder 66 is connected to pin 35 and to the lifting boom by quick release pin 67. Cylinder 66 is energized from motor 20 to raise the lifting boom. It will be noted from Figure 1 that when the lifting boom is in a lowered, substantially horizontal position its head extends beyond platform 41 and is disposed rearwardly of the end of the device. When the lifting boom is raised it can be lifted to a position in which its head is inwardly disposed with respect to the bomb supporting platform. This structure enables a simple, inextensible boom of the type illustrated to be used to transfer a bomb from the ground onto the bomb supporting platform. The lifting boom can then be raised to a position in which it normally will not interfere with the loading: operation, or, in some circumstances, it may be desirable to remove the lifting boom. The lifting boom is biased in the same ver- Figure 3 shows the details of the platform and mount- 1 ing base structure. A threaded adjustment member 68 is mounted by collars 69 and 70 in a transverse member 71, which connects the ends of lower lifting arms 38. The threaded portion 72 of member 68 threadably engages a flange 7 3, which is shown partially broken away and which is part of mounting base 37. Pin 40 is mounted on flange 73. Accordingly, rotation of adjustment member 68 changes the position of pivot pin 46 with respect to lift ing arm 38a, causing the platform to be tilted. Member 38 is slotted to receive pin 40. Adjustment members 68 can be used to set a desired angle of inclination of platform 41 with respect to the horizontal before the bomb is lifted, or, alternatively, it can be used to make minor adjustments to the inclination of the bomb when it has been raised into position.
Rotary movement of the platform is obtained by mounting the base plate 74 of the platform on a drum 75, which engages with a corresponding drum 7 6 mounted on mounting base 37. If desired, a roller bearing 75a can be provided between drums 75 and 76 (as is shown in Figure 5 i The drums can be retained by friction, or, if desired, locking means (not shown) can be used to lock the drums with respect to each other. The inclusion of provision for rotary movement of the platform is an important and useful adjunct, as it would be insuflicient'for complete flexibility of adjustment to provide for movement of the platform in any horizontal direction. The direction of the longitudinal axis of the bomb is also an important factor in correctly positioning the bomb.
A side frame 77, consisting of parallel channel-shaped members 78 and connecting members 79, is mounted on base plate 74 for slidable transverse movement by rollers 80 and flanges 81. Flanges 81 have a portion secured to members 78 and a portion 82 which locks under base plate 74. A control member for transverse movement 33 is journalled in frame member 78 and fitted with a pinion 84 which meshes with a rack 85 mounted on base plate 74. Hence rotation of control member 83 will cause the side frame to move transversely with respect to base plate 74. A top plate 86 is slidably mounted on side frame 77 by flanges 87, which have a portion 88 secured to end pieces 79 and a portion 89 overlapping; top plate 86. A control member 90 threadably engages a block 91 which,
is secured to channel-shaped members 78. The end of control member 90 is journalled in a block 92 which is secured to top plate 86. Rotation of the control member for longitudinal movement 90 thus moves top plate 86 forwardly or rearwardly with respect to the side frame. Transverse members 46 for supporting the bomb holding means are mounted on plate 86.
Figure 4 illustrates that, if desired, a maintenance platform 93 can conveniently be mounted on the bomb supporting platform. The maintenance platform shown includes a base member 94, upright members 95, transverse members 96, connecting the upper portions of upright members 95. One or more of transverse members 96 is preferably pivotally mounted as shown at 97 and releasably connected as shown at 98 to provide a gate. Platform 94 has a quick release connection 99 to a chock assembly 100. The chock assembly includes U-shaped members 101, the bases of which are adapted to rest on rollers 42, and quick release connection 102 to plates 43.
