HARROW.

Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed December 16, 1905. Serial No. 292,079.

To all whom, it may concern:

Be it known that I, JAMEs M. ULsH, a citizen of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented a new and useful Harrow, of which the following is a specification.

The invention relates to improvements in harrows.

The object of the present invention is to improve the construction of that class of toothed harrows having automatically-ad justable sections to accommodate the harrow to unevenness of land and to provide a simple and comparatively inexpensive harrow of this character of great strength and durability which will be capable of vertical adjustment to regulate the depth of cut and to elevate and lower the barrow-frame to suit various conditions of soil and in which there will be an increased clearance capacity by eliminating all parts at the center of the harrow that would tend to accumulate rubbish and prevent the free passage of the same therethrougli A further object of the invention is to improve the construction of the harrow-frame and the means for both hinging the sections and mounting the inner ends of the toothbars for rotary adjustment.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claims may be re sorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective View of a spring-tooth harrow constructed in accordance with this invention. Fig. 2 is a central longitudinal sectional view, the central frame bar or member being shown in elevation. Fig. 3 is an enlarged detail sectional view taken transversely of the harrow, illustrating the manner of mounting the inner and outer ends of the rotary toothbars. Fig. 4 is an enlarged detail plan view, partly in section, illustrating the construction for mounting the inner ends of the rear toothe bars. Fig. 5 is a detail elevation illustrating the construction of the adjustable side wheels for raising and lowering the harrow-frame. Figs. 6 and 7 are detail views illustrating the construction of the caster-wheels. Fig. 8 is a detail perspective view of one of the hinge brackets. of the hinge element which cooperates with the bracket.

1 and 2 designate hinge-sections of a harrow-frame, the frame bars or members of which are preferably constructed of channelbars consisting of a vertical web and upper and lower horizontal flanges; but any other form of angle-iron bar may be employed in the construction of the frame of the harrow. The barrow-frame section 1, which is ap proximately U-shaped, is composed of an outer longitudinal frame bar or member 3 and an inner central longitudinal frame-bar 4, which is connected at the front of the harrow-frame with the outer member or side bar 3 by an integral front bar or member 5 and which is common to both sections of the harrow-frame and extends from the front to the back thereof, the inner ends of all of the toothbars 6 and 7 of the harrow being connected with and supported by the said. central longitudinal frame bar or member 4. The harrow-frame section 2, which is approximately Lshaped, consists of a longitudinal side frame bar or member 8 and an integral front frame bar or member 9, which is connected with the section 1 at the front end of the central frame bar or member by a hinge 10 of any preferred construction.

In Figs. 1 and 2 of the accompanying drawings three tooth-bars are shown in each set; but it will be apparent that any number of tooth-bars may be employed 'to provide a harrow of the desired capacity. The toothbars, which are tubular and which are capable of rotary adjustment, have their outer ends journaled in bearings 11, consisting of 1 attachment plates or portions and annular.- f

bearing-flanges 12, which form sockets for Fig. 9 is a detail perspective view IOC the reception of the outer ends of the toothbars. The attachment plate or portion of each bearing extends horizontally in advance and in rear of the socket or bearing portion and is secured to the inner faces of the outer longitudinal frame bars or members by bolts 13 or other suitable fastening devices, which pierce the attachment plate or portion and the webs of the said side bars or members. The inner ends of the front and intermediate tooth-bars 6 of the section 1 are supported by bearings 14, similar in construction to the bearings 11 and composed of attachment plates or portions and. annular bearing-flanges 15, which receive the inner ends of the said tooth-bars 6. The inner ends of the front and intermediate tooth-bars 7 of the harrowsection 2 are connected with the central frame bar or member 4 by interfitting hinge elements, which form a combination hinge and journal to hinge the sections of the harrow-frame together and to afford the toothbar 7 a rotary movement. One of the hinge elements consists of a bracket 16, having an attachment plate or portion and provided with a pair of spaced perforated ears or lugs 17, which receive between them the other hinge element 18. The attachment plate or portion of the bracket is secured to the central longitudinal frame bar or member in the channel thereof by means of bolts 19, each bolt piercing the bracket, the web of the frame bar or member, and the attachment plate or portion of the proximate bearing 14. The interfitting hinge element 18 consists of an eye 20 and a tubular journal 21, the eye being provided with a horizontal bore or opening to receive a bolt 22, which forms a pintle for the hinge and which also passes through the projecting ears or lugs of the bracket 16. The hollow journal fits within the inner end of the contiguous tooth-bar and is provided with an outer end wall 23, having a central perforation 24, through which is passed a tie* rod 25. The tie-rod is provided at its inner end with a head 26, which engages the inner, face of the end wall 23 of the hollow our nal. The eye of the interfitting hinge member 18 is also provided with a central opening 27, which communicates with the tubular journal and which permits the tie-rod to be passed through it and engaged with the end wall of the journal. The outer end 28 of the tie-rod is threaded to receive a nut 29, and it pierces the attachment plate or portion of the proximate outer bearing 11 and the web of the contiguous outer longitudinal frame bar or member. The nut 29 engages the outer face of such frame bar or member, and the tierod maintains the parts in the interlocked relation shown in Fig. 3 of the drawings, the journal being fitted in the inner end of the tooth-bar and the outer end of the latter being fitted in the annular bearing flange or socket of the outer bearing. This construction also admits of the necessary rotary movement of the tooth-bar to effect an ad.- justment of the harrow-teeth 30 and at the same time hinges the sections of the harrowframe together and permits the same to yield or adjust themselves automatically to the unevenness of the land. These harrow-teeth are constructed as shown and described in a copending application filed by me on or about July 29, 1905, Serial No. 271,802.

The rear end of the central frame bar or member terminates short of and is spaced from the inner end of the rear tooth-bar, which extends to and slightly beyond the center of the rear portion of the harrowframe to afford a support for a central rear harrow-tooth 31, which is disposed in longi tudinal alinement with the central longitudinal frame bar or member 4. The inner end of the tooth-bar 6 is connected with the rear end of the central frame bar or member by means of a bracket 32, consisting of an attachment portion 33 and an arm 34, extending rearward and laterally from the central frame bar or member to offset the tubular bearing portion from the longitudinal plane of the said member 4. The inner end of the rear tooth-bar 6 extends inward from the tubular bearing portion of the bracket 32, as clearly illustrated in Fig. 4 of the drawings, and provides a projecting tooth-supporting portion or extension lying immediately in rear of the central frame bar or member 4. The rear tooth-bar 6 is maintained against longitudinal movement in its bearings by means of a suitable key 35, located contiguous to the bracket 32; but any other suitable means may be employed for this purpose. The other rear tooth-bar 7 is supported. by interlocking hinge elements, one of the elements consisting of a bracket 36 and the other hinge element 37 consisting of an eye 38 and a rearwardly-extending arm or body portion, which terminates in a tubular bearing or socket 39, open at the outer end and having an end wal 40 at the inner end to form an abutment for the inner end of the rear tooth-bar 7. The bracket 36 is provided with a pair of projecting ears or lugs 41 to receive the pintle, which passes through the eye 38. The attachment plate or portion of the bracket is secured to the central frame bar or member by means of bolts 42,

which also pierce the web of the frame bar or member and the plate or attachment portion of the bracket 32. The rear toothbar 7 is retained in the bearing of the hinge element 37 by means of a tie-rod 43, which passes through an opening of the said end wall 40 and which also pierces the web of the frame bar or member 8. The head of the tie-rod engages the end wall, and its nut 44 engages the frame bar or member.

The sections of the harrow are supported at the outer sides by means of rear wheels 45, mounted on spindles 46 by L-shaped levers 47, consisting of short approximately horizontal arms and long upwardlyextending arms, which terminate in suitable grips or handles 48. These L-shaped operatinglevers are fulcrumed at their angles on the frame bars or members 3 and 8 by means of bolts 49 and are adapted to be oscillated to raise and lower the harrow-frame for adapting the harrow to different conditions of soil. The levers are secured in their adjustment by bolts 50, which pierce the upright arms of the levers and which also extend through the perforations 51 of the curved bars 52, mounted on the harrow-frame at opposite sides thereof and having vertical arms 53, which are bolted or otherwise secured to the frame bars or members 3 and 8. The perforations of the arcuate bars 52 are arranged at suitable intervals; but any other form of locking device may be employed for securing the levers and the harrow-frame in their adjustment. The sections of the harrow-frame are also sup orted by front caster-wheels 54 and a centra caster-wheel 55. The front casterwheels 54 are located at the front frame bars or members 5 and 9, and each wheel 54 is mounted in a forked or bifurcated standard 56, which is adjustably secured to a vertical pivot or stem 57 by means of a bolt 58 and a tooth 59, which engages a ratchet-face 60 of the vertical pivot or stem 57; but any other suitable means may be provided for effecting this adjustment, as will be readily under stood.

The pivot or stem 57 is arranged in a vertical bearing or eye 61 of a bearing-bracket 62, which is bolted or otherwise secured to the harrow-frame, as clearly shown in Fig. 6 of the drawings. The vertical stem or pivot 57 is retained in the eye or opening of the bearing-bracket by means of a suitable pin or key 63. The caster-wheel 55 is mounted in a similar manner, and its bearing-bracket is bolted to the central frame bar or member 4 in rear of the intermediate tooth-bars, as clearly shown in Fig. 2 of the drawings. The wheels are adapted to readily pass over all rubbish, and they prevent the same from accumulating in front of and being carried forward by the harrow, and in order to afford a maximum clearance capacity at the center of the harrow the longitudinal bar or member 4 is provided between the tooth-bars with upwardly-extending arched portions 64. All parts which might tend to obstruct the free passage of rubbish through the harrow are eliminated at the center, and this, together with the employment of the central wheel and the arched portion 64, greatly increases the clearance capacity of the harrow. The sections of the harrow-frame are independently supported by the caster and side wheels, which do not interfere with the operation of the hinge connection between the sections of the harrow-frame.

The tooth-bars are adjusted by means of levers 65, suitably fixed to the rear toothbars and connected with the intermediate front tooth-bars by means of longitudinal bars 66 and arms 67, which extend upward from the said tooth-bars. The connectingbars 66 also carry toothed segments or ratchets 68, which are arranged to be engaged by spring-actuated dogs or detents 69 of the operating-lever 65. Any other suitable means, however, may be employed for rotating the tooth-bar to adjust the harrow-teeth, and the latter may be of any desired number, and any preferred arrangement of the harrowteeth may be employed.

The front frame-bars 5 and 9 are provided with eyes 70 or other suitable means for the connection of a draft attachment.
