This invention is concerned withthemanipulation of the massivebooms with which the claims.
street payers and various other chines are equipped. p y 1 Heretofore' it has been the practice to to swing such booms from one position to large maanother by hand, *owi-ng'to the fact that ore dinary poweroperated mechanisn'is will not withstand without 1n ury the severe shocks set up therein by the resistance 'ofthe boom in being started or stopped.
The principal object of the invention is to provide "a power operated boom-swinging mechanism which will absorb within the same all of the severe shocks encounteredin swinging a boom from 'oneposition 'to an other. p p I Other ObJBCtS and advantagesnot specltically referred to in this disclosure will be .1 appreciated by those skilled in'the artupon a full comprehension of the construction, in I rangement and manner of operation of the mechanism. A
F or the purpose of 'exemplilication, one embodimentof the inventionis presented in the accompanying drawings and in the fol lowing detailed description, but as nume'rou's other modified embodiments are also 'ob-,
viouslywithin the purview of the invention,
" the form here presentedisnot to'b'e con sidered as limiting the spirit of the inven' tion short of its intended scope as defined in In the drawings v 5 Fig. 1 is a fragmentary side view of a street paver or other machine equipped with the mechan smof the invention;
and
Fig.3 is a section taken vertically through Y -'wh1ch 1s meshed wlth the gear- 18 and is the center of the mechanism. 7
It will be observed in the drawings that the boom-swinging mechanism of the invention is illustrated in association with a road paver or other large machine having a in a vertical plane aboutits point of attachment with the trunnion. Q The other end of the trunnion 13 extends above the collar by a number of bolts 17.
p A gear 18 is journalled on the trunnion 13 12 and is there connected with a spider 16 between the spider 16 and the collar 12, and
is yieldab'ly connected with the spider by two sets of interleaved friction -dis'ks19 and 20 which are keyed respectively to the gear and the spider. in either direction by a suitable power train".
which will be hereinafterdescribed. The two sets of disks 19 and 20 are pressed into The gear 18 is oscillated which are mounted in the spider. The disks Y and associatedparts may be advantageously housedwithin a sheet metal casing'24 of CYllIlClIlCiLlfOTII].
p v The multiple disk arrangement herein de- SCIlbGdPlOVlClGS a yieldable but effective torque "transmitting connection front the gear 18 to the boom 14, which connection will cause the boom to move as a unit with the gear when no undue resistance is offered by the boom, but will permit, momentary "slippage between the same when any high I resistance is abruptly offered by the boom due to the inertia in starting to swing or to the momentum in stopping. I
The power train for oscillating the gear 18 in either direction to swing the boom may obviously assumeany one of several forms. but is herein disclosed'as including a worm securedon a shaft 26. The shaft 26' is rotated in either-direction by two opposite ro- "which are secured to the shaft, the disks 30 bein shifted axially of the shaft by links 31 whic are carried by sleeves 32 on the shaft, and the sleeves32 in turn being shifted by suitably fulcrumed shifting yokes 33. The
in order to permit operation of the same in yokes 33 may be coupled together by links 3% unison from a control handle 35 located at one side of the machine in a position con venient to the operator.
The gears 27 and 28 are'rotated in opposite directions by two gears 36 and '37 with which they respectivelymesh. The gears 36 and 37 are secured to two axially aligned shafts 38 and 39 which are provided at adjacent ends with opposed bevel gears a0 both of which mesh with a bevel gear 41 on a shaft 42. The shaft 42- is continuously rotated in one direction from a suitable power source mounted on the machine. 7
It will be evident from the construction above described that when the control handle 35 is in a neutral position, both of the gears 27 and 28 will rotate freely on the shaft 26,
and the worm 25 in mesh with the gear 18 will remain at rest;'that when the handle 35 is moved one way, the gear 27 only will be clutched to'the shaft 26, and the worm 25 will rotate in one direction to oscillate the gear 18 slowly and cause the boom to swing as soon as the shock on the power train caused by the 'lIlQItlEL of the boom in starting has been absorbed by the connection between,
the gear 18 and the 'boomyan-d that when the handle 35 is moved the other way, the boom will be swung in the'opposite direction. a a
I claim:
1 A mechanism for swinginga pivotally mounted boom, including a power operate-d gear mounted in axial alignment with the pivotal axis of the boom, aset of friction disks in non-rotatable association with the gear, another coacting set of frictiondisks in non-rotatable association with the boom,
and springs for pressing the disks of one set into frictional engagement withtlie, disks of the other to efiect a frictional torque transmittingconnection between the gear andthe boom. V
2. ,A mechanism for swinging a pivotally disks of'the other to efl'ect a frictional torque transmitting connection between the gear and the boom, and means for adjusting the amount of pressure applied tothe disks by the springs. I I
A mechanism for swinging a pivotally mounted boom, including a bracket having a collar from which the boom is supported, a trunnion journalled in the collar and secured to the boom, a spider secured to the trunnion and provided with a peripheral flange, a
power operated gear journalled on the trimnioii, a thrust ring positioned about the spider in spaced relation to the flange, two interleaved sets of friction disks connected respectively with the spider and the gear,
springs interposed between the friction disks and the ring, and means interposed between the ring and the flange for adjusting the position of the former toward or away from the latter.
4. A mechanism for swinging a pivotally I mounted boom, including a power-operated mountedin axial alignment with the pivotal axis of the boom, a friction disk con nected with the gear, another coacting frictioii disk connected with the boom, and
springs for pressing the disks into frictional engagement with each other to effect a frictional torque transmitting connection between the gear and the boom.
'Intestiinony'whereof I have hereunto sub- I scribed my name.
