TOOTH SUPPORT FOR GULTIVATORS.
Application filed December 11, 1926. l' Serial No. 154,141.
My invention relates to improvements in tooth supports for cultivator-s, and the object of the invention is to provide simple means for resiliently supporting theharrow teeth of the type disclosed in my prior Canadian Patent #126,95 l, dated July 12th, 1910, and as disclosed in my prior United Eltates Patent #984,042, dated February 14th, 1911, so that the tooth will readyield either in a lateral direction when brought into engagement-'wit-h an obstruction in the field, such as a stone or root, and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained.
llig. 1 is a perspective view of two frag mentary portions of a barrow frame and a iarrow tooth and means for supporting the tooth between such portions.
Fig. 2 is a transverse sect-ion through the barrow tooth supporting means.
in the drawing like characters of reference indicate corresponding parts in each figure.
1 and 2 are two angle barrow :li'rame which extend parallelly and are provided with brackets 1* and 52* secured thereto, a bracket 1 and 2 being mounted each bar 1 and 2 and provided with aligned orifices 1 and 2.
3 is a bar extending between the members 1 and 2 and bearing against the inner face of each bracket 2* in proximity to each end of thebar 3. g 7
i is a rod secured at its ends in theorifices 1 and 2 and extending freely through an orifice 3 at each endof the bar 3.
5 is a compression spring surrounding each rod t and extending. between the bar 3 and each bracket 1*.
6 and 7 are spacing collars driven into the end of the spring 5 and surrounding the rod at so as to hold the spring in spaced relation thereto.
The brackets 1 are secured to the bars 1 and 2 by means of bolts 8 extending through slots 9 formed in each bar 1 and 2 so as to bar members of a permit of the brackets 1. being adjusted longitudinally of such bars to vary the compression of the springs 5.
lt will thus be seen that when the harrow is drawn in the direction of arrow see Figure 1 and the tooth 10 which is supported in the usual manner by the shank 11 from the bar 3 strikes an obstruction such as a stone indicated at X. lVhen such stone engages with the inclined edge of the tooth it forces such tooth in the direction of arrow A this movement being permitted by the yielding of the bar 3 in an angular direction against the pressure of the springs 5, the bar 3 being tilted during this movement, its upper edge bearing against the brackets .2 and forming the pivotal point of themovement. Should the opposite inclined side of the tooth 1O strike the obstruction it is forced in the opposite direction to that indicated by the arrow A, the lower edge of the bar 3 fulcruming on the brackets 2 so as to proried back to its normal position after such.
obstruction is passed.
What I claim as my invention is: y
1. The combination with two parallel members of a barrow frame, of a bracketsupport carried by each frame ll16l11b1,.t bar forming a harrow tooth carrier and extending between the frame members and bearing against the bracket support, means for mounting the bar member on such bracket supports so that it will swing in either direction using its upper or lower edge as a fulcrum, and resilient means resist-.
ing such movement.
2. The combination with two parallel members of a harrow frame, of opposing brackets carried by each frame member, a rod extending between each of such oppos ing brackets and secured thereto, a bar member extending transversely of the harrow frame members and through the ends of which the aforesaid rod freely extends, a barrow tooth extending from the bar mem-- her, and a compression spring surrounding each rod and bearing at one end against the bar member and at the opposite end against the opposing supporting bracket remote therefrom.
HENRY SMITH.
