GEORGE ERNSHAW GARRETSON, OF RUSSELLVILLE, KENTUCKY.
RuNNlNe-GEAR FOR VEHICLES.
SPECIFICATION forming part of Letters Patent No. 328,933, dated October 27, 1885.
Application tiled August 3, 1885.
To all whom it may concern.-
Be it known that LGEORGE E. GARRETsoN, a citizen of the United States, residing at Russellville, in the county of Logan and State of Kentucky, have invented a new and useful Improvement in Running-Gear for Vehicles, of which the following is a specication,reference being had to the accompanying drawings.
My invention has relation to improvements in running-gear for vehicles, especially adapted for use in connection with buggies or light wagons; and the novelty consists in the peculiar construction, combination, and arrangement of the various parts for service, substantially as hereinafter fully set forth,and particularly pointed out in the claims.
The object of my invention is to combine simplicity, durability, and strength of construction in a running-gear for vehicles of the side-bar class with cheapness of manufacture, capability of ready detachment of the various parts for repairing, and the necessary resiliency of the springs when traveling on rough roads or streets.
In the drawings hereto annexed, Figure l is a top plan view of a running-gear embodying my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a bottom plan view. Fig. 4 is a detached detail view of the head-block or plate ,of the front axle, showing the means for pivoting the said axle and connecting the perch or reach and springs thereto. Fig. 5 is a detached detail view of the manner in which the rear end of the perch or reach and springs are connected to the rear axle. Fig. 6 is a detailed sectional view of the front end of the reach or vperch and axle, showing the means for permitting the reach or perch to slide or recede under a heavy pressure on the springs.
Like letters of reference indicate like parts in all the figures of the drawings.
y Referring to the drawings, A A designate the front and rear axles respectively, connected together by a perch or pole, B, as will be more fully described presently, the rear axle, A', being arranged on a plane slightly above the plane of the front axle, and braced against lateral play or displacement by side braces,0 G,which are bolted or otherwise connected at their front ends to opposite sides of the perch-pole at about the middle thereof,
Serial No. 173,454. (No model.)
and at their rear ends said braces are secured or bolted to the rear axle, A', by means of clips or bolts, a brace being arranged on each side of the perch-pole and connected thereto and to the outer ends of the said axle, as described.
D D designate the springs, of any preferred construction, said springs being arranged on each side of the perch-pole B, at a short distance therefrom, and running nearly parallel therewith, the springs herein shown having `each an upwardly-curved central portion, del, arranged considerably above the plane of the perch-pole and axles. The front and rear ends of each spring D are located below the plane of the curved portion d thereof, and extend each other and" constituting a single casting for lightness and strength and simplicity. The body e has a central aperture or opening therein for the passage of a king-bolt, E', having a nut, E2, which bears against the lower surface of the body e, said bolt Ffserving as the pivot on which the front axle turns.
The bolt E' passes through the body e, the
axle, a bearing-plate, E3, secured on the `up'- per face of the axle by means of bolts passed through side arms E* thereof, and an upper bearing-plate, E5, adapted to bear on its lower 'surface on the plate E3, and receive on its upper surface the head of the king-bolt E. The plate E5 has projecting ears or lugsh h,arranged parallel with thelug e and platee3 of the headblock E, said lugs h h being perforated for the passage of securing-bolts h h', the upper headed ends Vof which bear on the lugs h h, while the lower screw-threaded ends thereof are passed through apertures formed in the lug-e2 and plate e3 fortheir reception, and receive securi ng-nuts h2 h2, which bear on the lower surface of said lug c2 and plate e3, thus securely and firmly connecting the several parts toroo gether, while permitting of the axle turning f thereon in the movements required to .turn
corners or angles. The outer ends of the side arms e to which the front ends of the springs D are connected, are cut away to provide a pin-0r bearing, around which the ends of the springs may be bent or pivoted, so as to lie flush with the upper surface ofthe remaining portion of the arms e', the springs being prevented from becoming disengaged or misplaced llaterally by means of nuts e2, fitted or screwed on the screw-threaded pin or bearing of the arms d, thus providing a simple, strong, and efficient connection vfor the front ends of the springs D.
The rearwardly-projecting plate e3 is of considerable length, and fits against the lower surface of the reach or perch-pole B. This plate extends to a point at or near the middle of fthe perch-pole to provide a large area of bearing-surface therefor.
The -reach is freeto slide or recede from the front axle when any undue strain or weigh-t comes upon the` springs DD, said reach being provided with downwardly-projecting bolts i, which pass therethrough and work in longitudinal slots t" i', formed in the plate e3, near the ends thereof, a packing or lling of leather or any other suitable material, I, being arranged between the meeting surfaces of the reach and plate to deaden77 the noise incident vupon the movement of the bearing-surfaces of Jthe reach and plate.
The rear plate, F, is of a greater length tha-n the head-block E, and is secured upon the lowe-r surface of the rear axle at the middle thereof by means of clips or bolts F, the outer ends yof said plate being bent downwardly, as at f, and having a reduced or cut-away portionto provide a pin or bearing, f', around which the rear ends of the springs D D are bent Vor pivoted in a manner similar to the` front ends thereof, and prevented from becoming disengaged by nuts f2, screwed on the.
screw-threaded outer vends of said bearingsf.
The rear end of the perch-pole B terminates 1 pins or a shortdistance from the rear axle, and is proj a bent Yor curved portion, fg', and at i-ts rear@ end said .plate -is clipped or bolted to the under surfaeeof the -rear axle, as clearly shown.
H H designate longi-tudinal side bars, arranged above and at one side of leach of the;l springs D D, to which bars the body Yof veg? hicle, whether a wagon or buggy, is secured Iby any proper means-as, for instance, -the body may fbe bolted or clipped in the vusuali way directly to the bars, or it may have `transi verse bars at its front and rear ends, which;l project-beyondthe sides thereof and are bolted or clipped to said side bars, as is obvious.
J J J2 designate transverse supporting or holding bars, 'arranged about the middle ofthe perch, above the same, and extending transversely across the pole, as shown, said bars being bolted or clipped near their outer ends to the elevated curved portion of the side springs, D D, on which they rest and are supported thereby. The middle bar, J, is preferably made straight, while the outer ends of each of the bars J J 2 are curved outwardly, as at j, and away from each other, the extreme outer ends of each of the bars J J J2 being reduced or cut away, as at j2, and fitting under the side bars, H, to which they are secured by means of bolts or clips 7c, having securingvnuts k.
Between the lower surface of each of the bars YJ J2 J and the nuts k is arranged a plate, L, bent as at Z, and secured. at its ends to the lower surface Vof the side bars, H, by bolts vor otherwise, aplate being provided for each side bar, as clearly shown.
The side. bars are connected together to pre;- I
vent displacement'or play thereof, and add strength thereto, by cross braces or bars M M, one being secured at each side of the bars J J' J2 and to the bars H at its opposite ends and on the under surfaces of said bars H by bolts or otherwise.
It will be observed that the necessary re'- siliency is imparted to the body of the vehiele by the movement of the springs, which are pivoted at their ends, as described, to allow -the middle curved portions to give to a greater degree and allow a greater range of movement thereof without affecting the perch-pole; but when any undue weight or strain is imposed on said springs they are forced down still lower, and the perch-pole is caused to slide upon the plate by being drawn backward by the rear ends of the springs forcing the rear axle backward, thus imposing a portionof the ICO vgreatest strain upon the perch -pole and relieving the springs from a portion of the weight, the sliding movement of the perchpole separating the axles to a farther distance apart than their normal position, andallowing a further downward movement of thesprings. A running-gear constructed in accordance f with my invention possesses great durability and strength, is simple in construction, 4efficient -in operation, can be readily taken apart for repairing, Snc., and by reason of its great simplicity and freedom from complex mechanisms it can be vrepaired by any ordinary blacksmith or carriage-repairer.
lThe middle portions of each of the supporting-bars J J J2 fit or abut against each other,
and are 'bolted together by a through-bolt, m,
having a nut, m.
I am aware that heretofore it has been proposed to provide a wagon with a tubular portion rigidly secured to the rear axle and extending ynearly to the front axle and havin glimiting screws, a pole rigidly connected to the 5 fifth-wheel of the front axle and free to slide and rotate in said tubular portion of the rear axle. said pole having limiting recessed por- IIO IIS
tions in which the set-screws work, also, that it is not new to connect the springs pivotally to the axles.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
l. In ajrunninggear, the combination of the axles, plates e F, rigidly bolted to said axles and having reduced supporting-arms, side springs, D, pivotally connected to said axle-plates at the reduced ends thereof, a slotted plate, e3, formed with the plate e of the front axle, a perch-pole, rigidly secured to the rear axle and resting and free to slide upon the slotted plate e3, through-bolts ,to connect said pole and plate together and limit the movement of the pole, and a packing, I, of leather interposed between the pole and plate e3, as set forth.
2. In a running-gear, the combination of the axle, side springs arranged parallel with each other, a perch-pole, a head-block, pivotally connected with the axle and having side arms, e, to which the ends of the springs are connected, an upper bearing-plate secured upon the axle, a plate adapted to bear on the upperplate and connected to the head-block, and a king-bolt passing through the bearingplat-es, axle, and head-block, substantially as described.
3. Ina running-gear, the combination,with the rear axle and the side springs, of a plate boltedto the under side of the axle, and having a bent arm at each side, provided with a bearing for the rear end of one of the said springs, as and for the purpose set forth.
4. In a running-gear, the combination,with the axles ,a perchpole, and the side springs, of a plate secured to the under surface of each axle, and having lateral arms provided with bearings for the ends of the said springs, which are pivotally connected thereto, as set forth.
5. In a running-gear, the combination of the axles, the side springs, a perch-pole rigidly connected at its rear end to the axle and adapted to slide at its front end, a plate secured to the rear axle and having bearings for the rear ends of the springs, and a headblock pivotally secured to the front axle and provided with eud bearings for the springs, and a plate having slots adapted to receive the front end of the perch-pole and its securing-bolts, substantially as described.
6. In a running-gear, the combination of the side springs, the transverse supportingbars bolted together at their middle and to the elevated portions of the side springs, and parallel side bars bolted to the outer ends of the transverse supporting-bars and adapted to support the vehicle-body, substantially as described.
In testimony that I claim the foregoing as my own I have hereto aflixed my signature in presence of two witnesses.
