Referring more in detail to the drawings:

1 designates a frame of a truck or the like having a front axle 2 and a rear axle 3 with dual rear wheels 4' and front wheels 5. The frame of the tractor includes side rails 6 and 7 and mounted thereon is a turntable designated generally at 8' which comprises a gear rack 9. The vehicle includes a platform 10 rotatably mounted upon the gear rack 9, the platform including side rails 11 and 12. The gear rack 9 is located rearwardly of the frame of the vehicle and just in front of the rear wheels as illustrated in Fig. 1. The gear rack 9 has a central opening 13 and rigidly secured to the underneath side of the gear rack over the opening is a plate 14 for mounting a pedestal member or unit 15 for a purpose later described.

Rigidly secured to the underneath sides of the side rails 11 and 12 of the platform 10 is a plate member 16 forming a bearing for the platform and having a central opening 17 aligning with the opening 13 in the gear rack 9 and through which the pedestal 15 extends. The pedestal is provided with an olfset shoulder 18'. The pedestal is externally threaded as indicated at 19 for receiving a ring 20 and a threaded nut 21 for retaining the pedestal in place on the gear rack. The mating faces of the gear rack 9 and the plate 16 are provided with races as indicated at 22 and 23 for receiving ball bearings as indicated at 24.

Mounted upon the platform 10 is an engine 25 with a driving connection as indicated at 26 with pumps 27 and 28 for pumping of fluid from a reservoir 29 (Fig. 14) which may be carried on the vehicle in a suitable manner. A line 30 leads from the reservoir to the pump 28 and a line 31 from the pump 28 to a valve 32 which has connecting

lines

33 and 34 with

valves

35 and 36. The valves used in my fluid system are all four-way open center type. The valve 36 is connected by lines 37 and 38 to motors 39 and 40 carried by the rear and front axles respectively for driving of the vehicle. A return line 41 leads from the valve 3 5 to the reservoir 29.

The steering mechanism for the Wheels. is not shown in detail but is such as is used on four-wheel-drive trucks wherein the steering Wheels are all driven by fluid power.

42 (Fig. 13) designates a steering cylinder for the vehicle connected by lines 43 and 43' to a valve 44, a line 45 leads from the pump 27 to the valve 44. Other valves are connected .in line 45 as will later be shown. .A return line 47 leads from the valve 44 to the reservoir 29.

The front end of the frame 2 has a cross member 48 to which is rigidly secured a U-shaped bracket 49 provided with a bearing opening 50. The bracket engages over the front axle member 51 which is also provided with an opening 52 forming a bearing aligning with the bearing for receiving a pin 53 for securing the frame to the front axle of the vehicle and pivotally mounting the frame thereon.

The platform 10 of the vehicle is provided with a lateral extension 54 upon which is mounted a drivers seat 55 and has a valve panel arrangement as indicated at 56 and a steering lever 57. The valve panel is provided with a plurality of levers as indicated at 58 which are connected to a fluid mechanism as will later be shown,

Pivotally mounted upon the rails 11 and 12 of the platform by pins 59 are spaced arms 60 and 61 forming a standard 61 for boom 62. The arms 60 and 61 are connected by a cross member 63 near the bottom thereof and are tapered inwardly and are connected by cross member 64. Pivotally mounted between the upper ends of the standard 60 and 61 by pins or the like 65 is a tubular member 66 through which the boom 62 is adapted to extend and be moved relatively thereto.

The cross member 64 has rearwardly extending ears 67 to which is pivotally mounted one end of a doubleac'ting cylinder 68 having its other end pivotally mounted to ears 69' on the platform 10. A valve 71 is connected in line 45 and has lines 72 and 73 leading to the doubleacting cylinder or extension member 68 and upon manipulation of the valve 71 by the operator of the apparatus the standard 61' for the boom 62 may be moved forwardly and rearwardly with respect to the turntable as illus trated in Fig. 3.

Mounted on the underneath side of the tubular member 66 are depending ears 74 for pivotally mounting the end of a double acting cylinder 75 one end of which is pivotally connected to ears 76 mounted on the cross bar 63 of the standard 61'. A valve 78 is connected in line 45 and has lines 79 and 80 leading to the double-acting cylinder or extension member 75. By operation of the valve 78 the boom 62 may be raised and lowered by the extension member 75 also, as indicated in Fig. 3, through the pivotal mounting on the pivot pins 65 of the standard 61'.

The outer end of the boom is provided with a transverse shaft or pin 81 upon which is mounted a U-shaped bracket or head 82. Mounted within the U-shaped portion of the head 82 near the upper end thereof are ears 82' to which is pivotally mounted one end of an extension member or cylinder 83 having its other end pivotally mounted to ears 84 on the top side of the boom 62. A valve 85 is connected in line 45 and has

lines

86 and 86 leading to the cylinder 83 whereby upon operation of the pump 27 and valve 85 the extension member 83 may move the head fore and aft on the outer end of the boom as illustrated in Figs. 6 and 7.

Mounted at substantially the center of the bracket 82 by a pin 87 is a housing 88 for a shaft 89 carrying a tamping head 90. The housing 88 has its lower end provided with an open way 91 in which the shaft 89 is adapted to reciprocate. The housing also has

side walls

92 and 93 provided with aligned openings 94 and 95 in which are mounted short shafts 96 and 97 for mounting spaced crank members or pulleys 98 and 99. The crank members 98 and 99 are provided near one edge thereof with aligned openings 100 and 101 for receiving the ends of a shaft 102 upon which is mounted a sleeve arm 103 to each end of which are pivotally attached

arms

104 and 105, the free ends of which are pivotally attached to

helve links

106 and 107 the free ends of which are in turn pivotally attached to

cars

108 and 109 secured in the upper end of the shaft 89 carrying the tamper head 90. A helve spring 110 with its respective ends engaged in keepers 111 and 112 on the respective inner sides of the

arms

104 and 105 as illustrated in Fig. 12 is provided for exerting tension on the helve arms.

The crank members 98 and 99 are in the form of V- pulleys adapted to receive

belts

113 and 114 fitting over

pulleys

115 and 116 which in turn are mounted on a shaft 7 of a motor 118 mounted upon a top plate 119 driving the crank members for movement of the hammer through the helve arms as described.

The valve 35 in the line 33 has lines 120 and 121 8 leading to and from the motor 118 whereby operation of the pump 28 and valve 35, fluid will be added for the motor to operate the tamping head in successive blows through the helve link connection as described, a fluid return line 35 connects the valve 35 to return line 41.

It will be seen the hammer with its housing is rotatably mounted upon the pin 87 for operation of the hammer transversely of the bracket head 82. An arm 122 is at one end rigidly attached to the head 82 and an arm 123 at one end secured to the housing 88 for the hammer and the free ends of the arms are connected by a double acting cylinder or extensible member 124. A valve 125 is connected to line 45 and has lines 126 and 127 leading to the double acting cylinder 124 whereby operation of the pump 27 and valve 125 fluid will be supplied for operation of the extensible member 124 to turn the tamping head transversely of the bracket head 82 as indicated in Figs. 8 and 9.

Mounted upon the side 128 of the telescoping member 66 is a motor 129 having a shaft 130 provided with a worm (not shown) connected with a shaft 131 mounted in bearings as indicated at 132 on the top edges of the sides of the telescoping member 66 as best illustrated in Fig. 5. Mounted on the shaft 131 is a gear 133 meshing with gear or rack teeth 134 on the top of the boom 62. A valve 135 is connected in line 45 whereby the boom may be moved forwardly and rearwardly through the telescoping member 66 by operation of the pump 27 and valve 135 which in turn has lines 136 and 137 leading to the motor 129.

In Figs. 18 to 24, inclusive, 1 have illustrated apparatus whereby a multiple head compactor may be used on the boom in place of the single compactor unit. This form of the head includes a bracket member 138 pivotally mounted on the end of the boom the same as in the single tamping head unit and the same hydraulically operated extension member is used and the same numbers may be applied as in the preferred form. The same apparatus is used for mounting of the housing 139 on the head 138.

The housing 139 has

sides

140 and 141 connected by top plate 142 and a lower member 143 through which the

shafts

144, 145, 146 and 147 are adapted to engage through passageways as in the single unit structure. The

sides

140 and 141 are provided near the upper end thereof with openings 148 and 149 for shafts 150 and 151 upon which are mounted V-

pulleys

152 and 153 over which

belts

154 and 155 run to

pulleys

156 and 157 mounted on

shafts

158 and 159 of

motors

168 and 161 mounted upon the plate housing 142. Mounted upon the bottom plate 143 of the housing and extended upwardly therein are spaced supports 162, 163 and 164 having aligned openings for shafts 165, 166 and 167. Mounted upon the shaft 150 and 151 are helve crank

members

168 and 169. Also mounted upon either side of the supports 162, 163 and 164 and upon the shafts 165, 166 and 167 are crank members 170, 171, 172, 173, 174 and 175. The

crank members

168 and 170, 171 and 172, 173 and 174, and 175 and 169, are provided near their edges with shafts 176, 177, 178 and 179 for connection of

arms

180, 181, 182 and 183 which correspond to the arm 97 in the single tamping unit construction through which is connected the helve arms and link mechanism each one of which is of the same construction as the single unit head.

In Fig. 24 is diagrammatically illustrated the hydraulic mechanism for operating the movable tamping head construction and the reservoir 29 contains the fluid for the pump 181 connected by line 182 to the reservoir and has a line 183 leading to a valve 184 and line 185 to a valve 186 which in turn has lines 187 and 188 leading to

lines

189 and 190 respectively to

motors

160 and 161 for operation of the multiple tamping heads whereby operation of the pump 181 and valve 186 with valve 184 open the motors may be energized for operation of the tamping heads and it will be noted that the

heads

144 and 147 will operate in unison and 145 and 146 also in unison. A return line 191 is connected with valve 186 for return of fluid to the reservoir 29.

Referring to Fig. 16 of the drawings, the pedestal 15 is provided with a central passageway 192 closed at the top by a cap 193 and is connected at the bottom to the line 37 leading to the motors 39 and 40. The passageway 192 has connection with an annular passageway 194 having an opening for attachment with line 34 leading to the pump 28. A second annular passageway 195 is provided in the pedestal which has connection with line 41 leading from the valve 36 back to the reservoir 29 whereby operation of the motors 39 and 40 the driving of the vehicle is accomplished.

An annular passageway 196 is provided in the pedestal 15 having connection with line 33 to the pump 28 leading to valve 35 having connection with lines 120 and 121 to the motor 118 for operation of the hammers carried by the head of the compacting unit. An annular passageway 197 is also provided in the pedestal 15 having connection with line 198 which in turn connects with line 41 for return of fluid to the reservoir 29.

It will be seen in Fig. 16 that the various connections will have the usual packing as indicated at 199. The entire assembly is held in place by a threaded washer 200.

Mounted upon the side rail 11 of the rotatable platform is a motor 201 having a gear reduction housing 202 provided with a shaft 203 upon which is mounted a gear 204 meshing with the teeth 205 on the gear rack 9. The motor 201 is operated by the pump 27 (Fig. 13) forcing fluid through line 45 to a valve 206 having lines 207 and 208 connected with the motor 201. The valve 206 connects with the main return line 47 leading to the reservoir 29. Upon manipulation of valve 206 the motor 201 with connection through the gear 204 meshing with the gear rack will cause the platform to move on its bearing 16 around the gear rack whereby the platform may be moved laterally of the vehicle as illustrated in Fig. 3.

It will be seen that the platform may be rotated on the pedestal while the tamping operation is being performed and the various hydraulic mechanisms operated one independently of the other so that the head on the telescoping boom can be moved in the desired position.

Referring to Figs. 22 and 23 I have shown the compactor unit mounted on a caterpillar type tractor as indicated at 211 having the usual frame 212 and side traction wheels 213 and 21-4 with the gear rack 9 mounted on the frame and the platform 10 mounted on the gear rack as in the preferred form of the invention.

The compactor mechanism has hereinbefore been described.

. The driving of the caterpillar axles is accomplished the same as in the truck type shown in Fig. 1 and for steering the respective traction wheels 213 and 214 a valve 215 is connected in line 182 from the pump 181 and a line 216 leads to a valve 217 which in turn connects with the return line .191.

Lines

218 and 219 are connected with a motor 220 for steering one of the traction wheels and lines 221 and 222 lead from the valve 217 to a motor 223 for steering the other traction wheel. With this type of tractor one wheel may be moved forwardly while the other is reversed as is the usual practice.

It will be obvious from the foregoing that I have provided an improved compactor unit whereby the tractor may be driven to a desired location and the boom 62 moved to the desired position by operation of the motor 129 and the forward end may be raised and lowered by operation of the extensible member 75. The standard 61 may be also moved fore and aft of the tractor by operation of the extensible member 68 to move the boom towards or from the tractor and the head may be rotated transversely of the boom or fore and aft on the boom as desired as hereinbefore set forth. The platform may be rotated on its bearing to work from the side of the vehicle in either form of the invention.

It will also be obvious that the single compactor head may be used in either form of the invention or the multiple head as desired.

What I claim and desire to secure by Letters Patent is:

A compactor of the character described comprising, a mobile vehicle having a frame provided With a gear rack, a platform rotatably mounted on said gear rack, motor means carried by the platform and having a gear connection with the gear rack for swinging said platform around said gear rack, a standard pivotally mounted on said platform and extending upwardly therefrom, a tubular member pivotally mounted on the standard in upwardly spaced relation to said platform, extensible means connected to the platform and to said standard for selectively swinging said standard to fore and aft tilted positions with respect to the platform, extensible means connected to said standard and said tubular member for selectively swinging said tubular member fore and aft with respect to said standard, a boom slidably mounted in said tubular member, said boom having teeth on its upper edge, motor means on the tubular member having a gear cooperating with the teeth in the boom for extending and retracting said boom with respect to the tubular member, a head pivotally mounted on the forward end of the boom for selective swinging of said head on an axis extending transversely of said boom, a compactor housing pivotally mounted on said head on an axis in alignment with the boom and generally normal to said transverse axis, hydraulic extensible means connecting said housing and said head for selectively moving said housing to laterally tilted positions with respect to the head, and hydraulic extensible means connecting said boom and said head for selectively pivoting the head on the forward end of said boom to fore and aft selected positions relative thereto.
