To all whom, it may concern.-
Be it known that 1, PETER DENPHIS, a citizen of the United States, residing at Michigamme, in the county of Marquette and State of Michigan, have invented certain new and useful Improvements in Pressure and Moving Jacks, of which the followingis aspecification.
This invention provides a tool for compressing material to be stored in a small space and for moving heavy articles of merchandise.
The tool is practically designed for compressing paper when packing the same in cars or for shifting boxes or other packages or goods too heavy and bulky to be conveniently moved or handled by one person.
The jack consists of a pressure-head, a detent extended therefrom to hold it after being pushed forward while the operating-lever is returning to a starting or operativeposition preliminary to again being actuated to advance the pressure-head to further compress the material or shift the load, a power-augmenting lever pivoted to the pressure-head, a feed-dog attached to said power-augmenting lever, and an operating-lever linked to the power-augmenting lever and pivoted to the feed-dog.
For a full description of the invention and the merits thereof and also to acquire a knowledge of the detailsof construction of the means for eflecting the result reference is to be had to the following description and accompanying drawings.
While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof,
' still the preferred embodiment is shown in the accompanying drawings, in which Figure 1 is a perspective view of a jack embodying the invention. Fig. 2 is a side view thereof. Fig. 3 is a view of the jack as seen from the lower end. Fig. 4 is a horizontal section on the line as w of Fig. 1.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
The pressure-head 1 may be of any formation, depending upon the design and special use of the implement, and preferably consists of a plate the outer side of which is longitudinally depressed to provide a central space for the passage of a cord or other binding for securing the package or material after being compressed. A detent 2 extends from the rear side of the pressure-plate and also serves as a runner or shoe to support the pressure-head in upright position with reference to the horizontal supporting-surface upon which it rests when the implement is in operation. The detent is of such construction as to make positive engagement with the surface and hold the pressure head when moved forward during the interval of the operating-lever returning to a starting position preliminary to again advancing the pressure-head to further compress the material or to shift the load. The rear end of the detent is pointed, said point being adapted to engage with the surface to hold the pressureplate in the advanced position. In the preferable construction the detent comprises companion members which are transversely spaced and extend in parallel relation, the front ends of said members being laterally deflected to obtain a bearing against the pressure-head to which they are secured by suitable fastenings in any substantial way.
A power-augmenting lever 3 has pivotal connection with the pressure-head, and, as shown, its lower end is received between the members of the detent 2 and is mounted upon a pin 7, supported in transversely-alined openings formed in the members of said detent. A feed-dog 4c is pivotally connected to the lever 3, and to prevent weakening the latter said lever is widened to receive the pin 8, upon which the feed-clog 4: is pivotally mounted. In order to equalize the strain upon opposite sides of the lever 3, the feed-dog is composed of eomplemental members, one being arranged upon each side of the lever 3 and mounted upon projecting ends of the pin 8. The companion members of the feed-clog are rearwardly diverged, the purpose being to enable their lower ends to bite into the surface at widelyseparated points, so as the better to sustain the strain incident to moving the pressure-head forward in the operation of the implement. The members of the feed-dog curve rearwardly and downwardly, their lower ends being cleft to provide claws which readily bite into the surface and hold the dog during the operation of the jack either for pressing material or moving a load.
The operating-lever 5 is pivoted at its lower end to the feed-dog and is connected by a link 6 to the upper end of the power-augmenting lever 3. The lower end of the operating-lever 5 is arranged between the members of the feed-dog and is mounted upon a pin 9, supported in openings of the members comprising said feed-dog. Washers 10 are slipped IIO upon the pin 9 and come between the members of the feed-dog and opposite sides of the operating-lever, so as to properly space said elements. The link 6, like the parts 2 and 4., is composed of companion members which are arranged upon opposite sides of the levers 8 and 5 and are pivotally connected thereto by means of pins 11 and 12. The operating-lever 5 is of a length to enable the person using the jack to occupy a standing position, whereas the parts 1, 2, and 4 rest upon the floor or other supporting surface against which the material to be compressed may be placed or against which the load to be moved may rest. In the operation of the jack, the pressure-head is placed against the material to be compressed or the merchandise or load to be moved and the upper end of the operating-lever 5 is gripped and pressure exerted downward thereon to cause the rear end of the feed-dog 4 to bite into the surface, after which the upper end of the operating-lever is moved rearward or drawn toward the person. This movement causes the upper end of the power-augmenting lever 3 to move away from the material or load and its lower end to advance, said lever turning upon its pivotal connection 7 with the feed-dog 4. During this movement of the jack the pressure-head is advanced and moves the object against which it is placed forward. After the upper end of the operatinglever 5 has been moved rearward a proper distance, it is pushed forward, and at this instant the detent 2 bites into the surface or is held stationary in anymanner, and as the upper end of the operating-lever is moved forward the lever 3 is turned upon its pivotal connection 7 with the detent 2 and draws the dog 4 forward.
It is to be observed that in the operation of the lever 5 pressure is at all times exerted downward thereon to bite into the surface. As the operating-lever is oscillated to and fro the pressure-head and feed-dog receive an alternate or step-like movement.
In the event of the jack being utilized for compressing paper or other material its hollow face admits of the passage of a binder or cord between it and said material for securing the latter after it has been compressed.
Having thus described the invention, what is claimed as new is 1. In an implement of the character described, the combination of a pressure-head, a detent cooperating therewith, a power-augmenting lever having pivotal connection with said head, a feed-dog pivoted to said poweraugmenting lever, and an operating-lever pivoted to said feed-dog and connected to the up per end of the power-augmenting lever.
2. In an implement of the character described, the combination of a pressure-head, a detent extended from the rear side thereof and constituting a shoe or runner for sustaining the pressure-head in upright position, a power-augmenting lever having pivotal connection with the pressure-head, a feed-dog cooperating with said power-augmenting lever,
and an operating-lever pivoted to said feeddog and connected with the power-augmenting lever.
3. In an implement of the character set forth, the combination of a pressure-head, a detent cooperating therewith, a power-augmenting lever having pivotal connection with said pressure-head, a feed-dog pivoted to said power augmenting lever and comprising spaced members which are rearwardly diverged, an operating-lever pivoted between the members of said feed-dog, and means connecting said operating-lever with the poweraugmenting lever.
4. In an implement of the character set forth, the combination of a pressure-head, a detent cooperating therewith, a power-augmenting lever having pivotal connection with said pressure-head, a feed-dog comprising companion members arranged upon opposite sides of the power-augmenting lever and rearwardly diverged, an operating-lever inserted between the members of said feed-dog, means pivotally connecting said operating-lever to the'members of the feed-dog, and means connecting the operating-lever with the upper portion of the power-augmenting lever.
5. The herein-described. jack for the purposes specified, the same consisting of a pressure-head made hollow upon its outer side, a detent extended from the rear side of said pressure-head and comprising. spaced members, said detent forming a shoe or runner, a power-augmenting lever pivotally supported between the members of the detent, a feeddog comprising companion members arranged upon opposite sides of the power-augmenting lever, an operating-lever pivotally supported between the members of said feed-dog, and a link connection between the operating-lever and the upper portionof the power-augmenting lever.
