Try this code from my jsFiddle. Think this will help you and adds the functionality to you loading screen. The animation time and borders were added by me to test everything.

HTML:

<div id="outer">
    <div id="jpreBar"></div>
</div>

<input id="input" value="0" />
<button id="button">Update</button>

JS

$(document).ready(function(){
   $('#button').click(function(){
      var per = $('#input').val();

      var height = per;
      backgroundy = -176 + 176 * (per/100);
      margintop = 176 - 176 * (per/100);

      $('#jpreBar').stop().animate({
         'height': height + '%',
         'background-position-y': backgroundy + 'px',
         'margin-top': margintop + 'px'
      }, 5000, 'linear');
   });  
});

CSS

#jpreBar {
 border-radius:0%;
 -moz-border-radius:0%;
 -webkit-border-radius:0%;

 background-image: url("http://50.87.144.37/~projtest/team/design/yellowmedia/images/logo.jpg");
 background-repeat: no-repeat;
 background-position: 0px -176px;
 height: 0%;
 margin-top: 176px;

 animation: progress 2s linear infinite;
 -moz-animation: progress 2s linear infinite;
 -webkit-animation: progress 2s linear infinite;
 -ms-animation: progress 2s linear infinite;
 -o-animation: progress 2s linear infinite; 

 border: 0px solid black;
}

#outer{
 border: 0px solid black;
 height: 351px;
}
