Tamper attachment for vibratory plow and method of laying line and cable
First Claim
1. A tamper attachment for a vibratory plow vehicle of the type wherein vibrating means imparts vibrations to a plow which is used to plow a narrow, relatively shallow furrow to receive a line or cable, said tamper attachment comprising:
- (a) attachment means for attaching the tamper to the vibrating means of the plow;
(b) a housing fixedly secured to said attachment means;
(c) a tamper foot positioned below said housing in ground contacting relation for rapidly impacting the ground in response to vibrations transmitted by said vibratory means for closing and tamping the furrow opened by the vibratory plow;
(d) a pair of spaced apart, spring loaded tamper foot guide arms connected to said tamper foot and slidably mounted in said housing for transmitting rapid up and down movement from the vibrating means through the housing to the tamper foot; and
(e) a tamper adjustment arm connected to said tamper foot and mounted in said housing for limiting reciprocatory movement of the tamper foot guide arms.

Abstract
A tamper attachment for a vibrator plow vehicle of the type wherein a vibrator imparts vibrations to a plow which is used to plow a narrow, relatively shallow furrow to receive a line or cable. The tamper attachment comprises attachment means for attaching the tamper to the vibrating means of the plow and a housing fixedly secured to the attachment means. A tamper foot is positioned below the housing in ground contacting relation for rapidly impacting the ground in response to vibrations transmitted by the vibratory means for closing and tamping the furrow opened by the vibratory plow. A pair of spaced apart, spring loaded tamper foot guide arms are connected to the tamper foot and are slidably mounted in the housing for transmitting rapid up and down movement from the vibrating means through the housing to the tamper foot. A tamper adjustment arm is connected to the tamper foot and mounted in the housing for limiting reciprocatory movement of the tamper foot guide arms. A method of laying cable using the tamper is also disclosed.

7. A tamper for closing a narrow, relatively shallow furrow of the type formed in the ground to receive line or cable, said tamper comprising:
-
(a) vibratory means; (b) a housing fixedly secured to said vibratory means; (c) a tamper foot positioned below said housing in ground contacting relation for rapidly impacting the ground in response to vibrations transmitted by said vibratory means for closing and tamping the furrow; (d) a pair of spaced apart, spring loaded tamper foot guide arms connected to said tamper foot and slidably mounted in said housing for transmitting rapid up and down movement from the vibrating means through the housing to the tamper foot; and (e) a tamper adjustment arm connected to said tamper foot and mounted in said housing for adjustably tensioning the spring loaded guide arms for limiting reciprocatory movement of the tamper foot guide arms. - View Dependent Claims (8, 9, 10, 11, 12)
