AMBROSE LARKIN MOORE AND GEORGE DANIEL MOORE, OF NEW ORLEANS, LOUISIANA.
STUMP-CUTTING MACHINE.
T 0 all whom it may concern:
Be it known that we, AMBRosE L. MOORE and GEORGE D. MOORE, citizens of the United States, and residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved Stump- Cutting Machine, of which the following is a full, clear, and exact description.
Our present invention is intended more particularly as an improvement on the stump cutting machine forming the subjectmatter of Letters Patent #1,10-l-,535, granted to us on July 21, 1914. In the operation of the said cutting machine a cutter of a particular character is positioned above the stump and gradually fed downward to the latter and given a rotary motion until the complete stump is cut away, leaving minor roots only.
The prime object of the present invention is to provideimproved cutting elements in a machine of the character referred to.
The invention is characterized by a centering cutter to enter the stump to center and steady the cutter head as it advances into the stump.
The invention is further characterized by the provision of an auxiliary cutter element associated with the centering cutter and having relation to the main advance cutter in a way to relieve the latter of strain, the purpose of the relief being to enable us to dispose the main advance cutter knives at an angle of approximately sixty-two degrees, which results in the maximum efficiency and enables us to reduce the driving power to a minimum as well as to shorten the vertical dimension of the said main advance cutter head. i
The invention will be particularly explained in the specific description following.
Reference is had to the accompanying drawings forming part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which:
Figure l is a perspective view of our improved cutting means for stump cutters; and Fig. 2 is a vertical section.
In our improved cutter a head 10 is provided having suitable means to attach the same to the vertical driven shaft 11. In the example shown the head 10 has a socket to receive the lower end of the shaft 11 and is held by a set screw 12. The shaft 11 turns and is adapted to slide in any suitable bear- Specification of Letters Patent.
Application filed April 5, 1915.
PatentedDec. 21, 1915.
Serial No. 19,167.
ing 13 secured in any approved manner to an overhead support 14, which in practice is part of a frame on a wheeled vehicle or tractor, as in our patent above referred to.
At the lower end of the head 10 a centering cutter 15 is secured, preferably by means of a threaded stem 16 thereon which is received 1n a correspondingly threaded socket in the lower end of the head 10. On the head 10 seats 17 are provided having removable knives 18 secured by bolts 19 or equivalent means. The respective seats 17 and their knives 18 constitute the main advance cutter which is of inverted truncated cone shape and generally corresponds with the similar advance cutter in our patented construction above referred to.
An auxiliary advance cutting element 20 is provided in front of the knives 18. The said auxiliary cutter 20 is preferably secured in a transverse hole in the centering bit 15 to project at diametrically opposite sides of said centering bit. The cutting edges 20 of the auxiliary cutter element 20 flare upwardly approximately corresponding with the general disposition of the cutters 18 of the main advance cutter. At the lower side of the cutter element 20 is a depression 20 which presents shoulders 20 on the cutter element, so that a key 21 will serve to rigidly hold the cutter element in position in the bit 15.
Above the main advance cutter knives 18 and their seats 17, outer counter-boring knives 23 are provided which are bolted to the downwardly and forwardly inclined ends 22 of arms 22 on the head 10, the bolts being indicated by the numeral 2 1. In connection with the arms 22 we eniploy'a balance rim 25 which is welded or otherwise secured to the said arms at the ends 22 and serves the function of a balance wheel for the cutter head in addition to bracing and strengthening the arms 22.
The knives 18 of the main advance cutter in the present construction, as well as the outer counter-boring cutter formed by the knives 23, correspond in essentials with the advance and counter-boring cutters in our patent above referred to. In the present construction the auxiliary advance cutter 20 serves to materially relieve the main advance cutter knives 18, so that an advance cutter head of less height may be employed and will require the minimum of driving power, and at the same time enables us to hold the by Letters Patent, is
1. In a stump cutting machine employing a driven shaft adapted to be lowered for cutting away a stump, a cutter head embodying the following elements, to wit: a 15 main advance cutter on the head in general of inverted truncated cone shape, an outer counter-boring cutter following the said" main advance cutter, a centering bit on the cutter head in front of the said main advance cutter, and an auxiliary cutter element transversely disposed on the centering bit. 2. In a cutter head to be driven and loweredfor cutting away a stump, a main advance cutter carrying cutter knives and generally of an inverted truncated cone shape, an outer counter-boring cutter on the cutter head following the said main advance cutter, an auxiliary advance cutter and means to support the said auxiliary'cutter element in front of the said main advance cutter, the said auxiliary cutter element flaring upwardly to conform generally to the inverted truncated cone shape of the main advance cutter.
3. In a cutter head to be driven and lowered for cutting away a stump, a main advance cutter carrying cutter knives and generally of an inverted truncated cone shape, an outer counter-boring cutter on the cutter head following the said main advance cutter, a centering bit on the cutter head in front of the said main advance cutter and formed with a transverse hole therein, and an auxiliary cutter seated in the said hole of the centering bit and projecting at opposite sides thereof, the said auxiliary cutter fiaring upwardly to approximately conform to the inverted truncated cone shape of the main advance cutter.
In witness whereof we have signed our names to this specification in the presence of two subscribing witnesses.
